Your outstanding mortgage balance is a useful starting point when
calculating life insurance — but it is not necessarily the amount of cover
you actually need.
If you died while your mortgage was still outstanding, paying off the mortgage
could remove one of your household’s largest expenses. But your partner,
children or other dependants might still need money for everyday living costs,
childcare, education, other debts and the income your household has lost.
Equally, you may already have savings, existing life insurance, workplace
death-in-service benefits or other resources that reduce the amount of
additional protection required.
This is why there is no universal rule saying that everyone should buy life
insurance equal to their mortgage, a particular multiple of salary or any
other fixed figure. First consider
whether you need life insurance for a mortgage,
then use this guide to estimate how much.
This guide gives you a structured way to estimate your potential
protection gap by looking at what your family might need,
what resources would already be available and how your mortgage is structured.

complete UK guide to mortgage life insurance.

Is there a standard amount of life insurance you need?
No single amount or salary multiple is appropriate for everyone.
You may see rules of thumb suggesting that life insurance should equal a
certain number of years of salary.
Such shortcuts can provide a rough conversation starter, but they do not
automatically reflect your actual financial circumstances.
Two people earning exactly the same salary can need very different amounts
of cover.
Example
| Circumstance | Person A | Person B |
|---|---|---|
| Annual income | £50,000 | £50,000 |
| Mortgage | £80,000 | £320,000 |
| Children | None | Three young children |
| Partner’s income | £60,000 | £18,000 |
| Savings | £150,000 | £10,000 |
| Existing life insurance | £100,000 | None |
| Likely protection need | Potentially relatively modest depending on objectives. |
Potentially substantially higher because of the mortgage, dependants and loss of household income. |
This is why a needs-based assessment is more meaningful than simply multiplying
salary by a fixed number.
What is a life insurance protection gap?
Your protection gap is the difference between:
- the financial resources your dependants might need following your death; and
- the suitable resources already available to them.
Financial need − available resources = protection gap
Potential financial needs
- mortgage;
- personal loans;
- credit-card debts;
- household living expenses;
- childcare;
- education;
- funeral expenses;
- other financial support for dependants.
Potential existing resources
- existing personal life insurance;
- death-in-service benefits;
- savings;
- investments;
- other suitable assets;
- surviving household income;
- relevant pension death benefits.
Not every asset should automatically be deducted pound-for-pound.
Consider whether you actually intend that asset to be used for this purpose,
how accessible it would be following death and whether using it would create
another financial problem.
Step 1: Start with your current mortgage balance
If your main objective is helping your family keep the home, the outstanding
mortgage is usually the most obvious liability to examine.
Use the current amount you owe, not necessarily the amount
you originally borrowed.
Example
You originally borrowed £300,000 five years ago.
Your current repayment-mortgage statement shows an outstanding balance of
£257,000.
If you are calculating the liability today, £257,000 is normally more
relevant than the original £300,000.
Check your latest mortgage statement for:
- current outstanding balance;
- mortgage type;
- remaining term;
- interest rate;
- whether any part is interest-only;
- additional borrowing or secured loans.
How your mortgage type affects the amount of cover
The amount you owe today is only part of the calculation.
You should also understand what is expected to happen to that debt over time.
| Mortgage type | What normally happens to capital? | Protection consideration |
|---|---|---|
| Repayment mortgage | Capital should gradually reduce as scheduled repayments are made. |
Decreasing cover may be considered if the main objective is protecting the reducing debt. |
| Interest-only mortgage | Capital may remain broadly outstanding until it is repaid separately. |
A fixed level of cover may more closely reflect a liability that is not steadily reducing. |
| Part repayment / part interest-only | One part reduces while another may remain outstanding. | The protection requirement may need to reflect both components. |
Read our
Life Insurance for Repayment vs Interest-Only Mortgages
guide for a detailed explanation.
Step 2: Add other debts you want the protection to address
Your mortgage may be your largest debt, but it may not be your only one.
Consider whether you want money available for:
- personal loans;
- car finance;
- credit cards;
- secured borrowing;
- other outstanding financial commitments.
Be careful not to assume that every debt will necessarily transfer directly
to your family following death. The treatment of debts depends on ownership,
agreements and the estate.
The purpose of this calculation is instead to ask:
“Which financial liabilities would I want the people I leave behind
to have resources to deal with?”
Step 3: Consider how much household income would be lost
Paying off the mortgage does not replace the income of the person who died.
Your family may still need money for:
- food;
- energy;
- council tax;
- transport;
- insurance;
- clothing;
- property maintenance;
- childcare;
- education;
- other everyday spending.
Do not simply replace gross salary
Your full gross salary is not necessarily the amount your family would need
to replace.
Some expenses linked specifically to you may disappear or reduce.
At the same time, new costs can arise after death.
A more useful approach is to estimate the household’s likely
income shortfall.
Simple framework
Expected household spending
− surviving household income
= annual income shortfall
You can then consider how many years you would want additional support
to be available.
Step 4: Consider children and other family costs
If you have children or other people financially dependent on you, your
protection calculation may need to extend beyond the mortgage.
Potential costs can include:
- nursery or childcare;
- school-related costs;
- transport;
- clubs and activities;
- university or further education support;
- additional housing costs;
- support for a dependent adult;
- care costs.
Non-working parents can also have a significant financial value
Life insurance need should not be assessed only by salary.
A parent who earns little or no employment income may provide substantial
unpaid childcare, household management or care.
If that person died, the surviving household might need to pay somebody
else to provide some of those services.
Step 5: Consider immediate costs following death
In addition to longer-term financial commitments, death can create short-term
expenses.
These might include:
- funeral costs;
- travel for family members;
- legal or administrative costs;
- temporary childcare;
- time away from work;
- urgent household expenses.
MoneyHelper notes that life insurance can be used to help provide for people
who depend on you financially and can also contribute towards outstanding
debts and funeral expenses.
[2]
Step 6: Subtract existing protection and suitable resources
Once you have estimated what your household might need, consider resources
that may already be available.
| Resource | What to check |
|---|---|
| Existing life insurance |
Amount, term, ownership, beneficiaries and whether the policy is level or decreasing. |
| Death-in-service benefit |
Amount, eligibility, whether it is discretionary and what happens when employment ends. |
| Savings |
Accessibility and whether you actually want those savings used to repay the mortgage. |
| Investments | Current value, accessibility, volatility and intended purpose. |
| Pension death benefits | Scheme rules, nominations and potential benefits. |
| Partner’s income |
How much of the household’s future costs could realistically be supported from that income alone. |
| Other assets |
Whether they are genuinely available and whether selling them would be appropriate. |
The FCA’s current pure-protection suitability guidance specifically states
that, where advice is provided, existing insurance cover should be considered
when establishing a customer’s demands and needs.
[3]
How should death-in-service cover affect your calculation?
Some employers provide life protection as part of an employee benefits package.
This is often called death-in-service benefit and may provide
a payment linked to salary.
MoneyHelper recommends checking whether you already receive this protection
through work.
[1]
Example
If your salary is £50,000 and your employer’s scheme provides four times salary,
the potential benefit might be £200,000, subject to the actual scheme rules.
If your assessed protection need were £500,000, you might initially regard
that £200,000 as one resource when examining the gap.
But do not automatically treat workplace cover as permanent
MoneyHelper specifically warns that employment-based life protection may stop
when you stop working for that employer.
[1]
Consider:
- whether you expect to remain with the employer;
- how the scheme calculates benefits;
- whether cover changes with salary;
- whether the benefit is guaranteed or subject to scheme rules;
- who receives it;
- whether you want independent cover that follows you when jobs change.
Should savings reduce the amount of life insurance you need?
Potentially, but do not simply deduct every pound of savings automatically.
Ask what those savings are intended for.
For example:
A household might have £80,000 in savings, but:
- £30,000 may be an emergency fund;
- £20,000 may be intended for children’s education;
- £30,000 may genuinely be available for other needs.
Treating the entire £80,000 as available for mortgage repayment could therefore
undermine other financial plans.
The same applies to investments and other assets.
Ask:
- Is the money accessible?
- Is its value stable?
- Would selling the asset create other problems?
- Was the money intended for another purpose?
- Would the surviving family realistically want to use it?
Should you rely on State bereavement benefits instead of life insurance?
Some surviving partners may qualify for
Bereavement Support Payment, but eligibility and the amount
available depend on specific conditions.
It should not automatically be treated as a substitute for assessing your
household’s wider protection needs.
Current 2026/27 position
GOV.UK states that eligible claimants receiving the higher Bereavement Support
Payment rate can receive up to:
[4]
- a £3,500 initial payment; and
- 18 monthly payments of £350.
The standard maximum is:
- a £2,500 initial payment; and
- 18 monthly payments of £100.
Eligibility depends on matters including the claimant’s relationship to the
deceased and the deceased’s National Insurance record or certain work-related
circumstances.
[5]
Worked examples: estimating a mortgage life insurance need
These examples are deliberately simplified and are for illustration only.
Example 1: primarily protecting the mortgage
| Outstanding repayment mortgage | £240,000 |
|---|---|
| Other debts to cover | £10,000 |
| Additional family support wanted | £30,000 |
| Existing personal life insurance | −£50,000 |
| Savings specifically available | −£20,000 |
| Illustrative protection gap | £210,000 |
This does not mean £210,000 is automatically the correct insured amount.
It simply illustrates how existing resources can be considered alongside
identified needs.
Example 2: mortgage plus significant family protection
| Outstanding mortgage | £300,000 |
|---|---|
| Other debts | £20,000 |
| Estimated additional family support | £200,000 |
| Immediate / other costs | £15,000 |
| Existing life insurance | −£75,000 |
| Suitable savings | −£25,000 |
| Illustrative protection gap | £435,000 |
In this example, simply buying £300,000 of cover to equal the mortgage
would not satisfy all the financial objectives identified by the household.
Example 3: substantial existing workplace protection
| Mortgage | £250,000 |
|---|---|
| Other identified family need | £150,000 |
| Total identified need | £400,000 |
| Current death-in-service benefit | −£200,000 |
| Existing personal insurance | −£50,000 |
| Illustrative remaining gap | £150,000 |
However, the household should also consider whether it wants to rely on
employment-linked cover that could disappear after a job change.
Should you insure only the mortgage balance?
Sometimes that may reflect the objective.
For example, a couple may decide:
“If either of us dies, our priority is simply to remove the mortgage.
The survivor’s income and our existing assets should then be sufficient.”
Another household may instead decide:
“Repaying the mortgage would help, but the surviving parent would also
lose a large part of our household income and need money for childcare
and everyday living.”
Those are two different protection objectives and may justify very different
amounts of life insurance.
Should mortgage cover be level or decreasing?
The amount of protection you choose and the way it changes are separate
decisions.
Decreasing term life insurance
Decreasing cover reduces over the policy term and is commonly considered
for repayment mortgages.
It can make sense where your principal need is a debt that is also expected
to reduce.
Level term life insurance
Level cover maintains the insured amount during the policy term, unless
you make an allowed change.
It may be worth considering where:
- you have an interest-only mortgage;
- you want money beyond the mortgage;
- family living costs form an important part of the need;
- you want a fixed amount of protection.
Read our
Level vs Decreasing Term Life Insurance
guide for the full comparison.
How long should your mortgage life insurance last?
The amount of cover is only half of the calculation.
You also need to decide how long the financial need exists.
See also
how long mortgage life insurance should last.
Mortgage protection
If the main objective is protecting a mortgage with 25 years remaining,
you might initially consider protection over a similar period.
Family protection
Other needs might end at a different time.
For example, you might want support until:
- your youngest child reaches financial independence;
- your partner reaches retirement;
- a major debt ends;
- sufficient savings are expected to have accumulated.
How much life insurance do couples with a joint mortgage need?
With a joint mortgage, assess the financial consequences of
each person’s death.
See
single, joint and Dual Life Cover
and
Dual Life Cover.
Do not assume both people require exactly the same amount of cover.
Ask:
- how much does each person contribute to household income?
- who pays the mortgage?
- would the survivor continue working the same hours?
- would additional childcare be required?
- what existing protection does each person have?
- would the same amount of debt remain following either death?
Two separate calculations may be useful
| Need | If Partner A dies | If Partner B dies |
|---|---|---|
| Mortgage need | Assess | Assess |
| Lost income | May be higher/lower | May be higher/lower |
| Replacement childcare | Depends on role | Depends on role |
| Existing workplace cover | May differ | May differ |
You can then consider whether single-life policies, joint cover or another
structure appropriately addresses those needs.
Should you only insure the higher earner?
Not necessarily.
Salary does not represent every financial contribution a person makes.
A lower-earning partner may provide:
- childcare;
- care for relatives;
- school transport;
- household administration;
- part-time earnings;
- other unpaid work.
If that person died, the higher earner might need to:
- reduce working hours;
- pay for childcare;
- pay for additional support;
- change employment arrangements.
The economic effect of death can therefore be much larger than the person’s
salary suggests.
How should single parents calculate life insurance needs?
Single parents can have a particularly concentrated protection need because
children may rely heavily or entirely on one parent’s income and financial support.
Consider:
- the mortgage or housing cost;
- who would care for the children;
- how that guardian would meet additional costs;
- education expenses;
- existing savings;
- existing life cover;
- pension and workplace benefits;
- how long the children are expected to remain financially dependent.
MoneyHelper’s general guidance specifically identifies financial dependants
as an important factor when considering the amount of life cover required.
[1]
How much life insurance for an interest-only mortgage?
With an interest-only mortgage, do not assume that years of monthly payments
mean the capital debt has substantially fallen.
See
life insurance for repayment vs interest-only mortgages.
Check the current outstanding capital.
If £300,000 remains outstanding and your objective is to provide enough life
insurance to deal with that debt throughout the relevant period, a policy
deliberately reducing below £300,000 could become mismatched with that objective.
Level term insurance may therefore be more closely aligned with a fixed
interest-only liability.
What happens to your cover if you remortgage or borrow more?
Your insurance does not normally increase automatically because your mortgage does.
See
what happens when you remortgage or move home.
Example
Original life cover:
£220,000
New mortgage after moving home:
£350,000
Unless your existing cover is changed or additional protection is arranged,
the difference could create a substantial new gap.
Review life insurance if you:
- borrow more;
- move home;
- extend the mortgage term;
- switch repayment type;
- take a further advance;
- make major overpayments;
- repay the mortgage early.
A review does not automatically mean an existing policy should be cancelled.
The FCA’s current Pure Protection Market Study is specifically examining
intermediary incentives that could encourage consumers to switch protection
unnecessarily.
[6]
Should inflation affect how much life insurance you choose?
Potentially, particularly where the purpose of the policy extends beyond a
fixed debt.
£200,000 of household support available many years in the future may not have
the same purchasing power as £200,000 today.
This can be relevant where the policy is intended to provide money for:
- many years of living expenses;
- future education;
- long-term childcare;
- other expenses likely to rise over time.
Some policies offer increasing protection.
The way both benefits and premiums increase varies by product.
By contrast, where the main liability is a repayment mortgage expected to
reduce over time, decreasing cover may deliberately move in the opposite direction.
What if the amount of cover you want is too expensive?
Insurance has to be affordable enough to maintain.
If your initial calculation produces an amount of cover outside your budget,
do not automatically conclude that protection is pointless.
Instead, identify priorities.
For example:
- protect the mortgage;
- protect essential household income;
- protect important other debts;
- add broader family protection where affordable.
Depending on your circumstances, different amounts, terms or types of protection
may have different costs. See
how much mortgage life insurance costs.
FCA pure-protection suitability guidance specifically identifies both the
level of cover and cost as relevant factors when advised
recommendations are made.
[3]
Latest FCA position in 2026: why the amount of cover matters
Pure protection has received significant regulatory attention during 2026.
Updated suitability guidance — 26 June 2026
FCA guidance for advised pure-protection sales was updated on
26 June 2026.
It says firms taking reasonable care over suitability should establish the
customer’s demands and needs, including relevant information about existing
insurance.
When considering whether a policy is suitable, relevant factors include:
[3]
- the level of cover;
- the cost;
- relevant exclusions;
- limitations;
- conditions.
The guidance also says customers should be informed about relevant demands
and needs that are not met.
Eligibility guidance — 27 July 2026
FCA guidance updated on 27 July 2026 says firms should take
reasonable steps to ensure customers buy policies under which they are eligible
to claim the relevant benefits.
[7]
Consumer understanding
The Consumer Duty requires firms to focus on good outcomes for retail customers.
Current FCA guidance emphasises that customers should receive clear and
understandable information that enables properly informed decisions.
[8]
This is particularly relevant to life insurance because a very large headline
benefit can look attractive without necessarily explaining:
- whether that amount reflects the customer’s actual need;
- how long the cover lasts;
- whether the amount decreases;
- what exclusions and limitations apply;
- whether the premium remains affordable.
The Pure Protection Market Study
The FCA published interim findings from its Pure Protection Market Study on
29 January 2026.
It found that the market works well in many respects for consumers who purchase
protection, but identified a significant protection gap.
The FCA reported:
[6]
-
58% of adults did not hold a pure-protection product;
and -
of those without protection,
59% had never considered their protection needs.
These statistics relate to pure protection generally and should not be
interpreted as meaning that 58% of mortgage borrowers necessarily require
life insurance.
Instead, they demonstrate why assessing whether a protection gap exists is
currently a major focus for regulators and the protection industry.
As at 19 August 2026, the January 2026 interim report remains
the latest report published on the FCA’s official market-study page.
The FCA says it intends to publish its final report in Q3 2026.
[6]
When should you review the amount of life insurance you have?
Life insurance needs can change substantially over a long policy term.
Consider reviewing your protection when you:
- buy a home;
- move home;
- remortgage;
- increase or decrease borrowing;
- have a child;
- marry or enter a civil partnership;
- separate or divorce;
- change employment;
- lose or gain workplace benefits;
- experience a major income change;
- repay substantial debts;
- build significant savings;
- approach the end of your mortgage.
Reviewing cover does not automatically mean replacing an existing policy.
Existing protection may have been arranged when you were younger or healthier,
and replacement can involve new underwriting, different terms and a different cost.
Mortgage life insurance calculation checklist
Before deciding how much protection to consider, gather the following information.
- Current mortgage balance
- Mortgage type: repayment, interest-only or part-and-part
- Remaining mortgage term
- Other debts you want to address
- Monthly essential household expenditure
- Your take-home income
- Your partner’s or household’s other income
- Number and ages of financial dependants
- Childcare or education costs
- Existing personal life insurance
- Death-in-service cover
- Pension death benefits
- Savings genuinely available for protection needs
- Other suitable assets
- How long financial support would be required
Once you have this information, your assessment becomes much more meaningful
than choosing an arbitrary salary multiple.
Life insurance amounts available from Assura Protect
Assura Protect’s current Term Life proposition offers both
Level Term Assurance and
Decreasing Term Assurance.
According to Assura Protect’s current product information:
[9]
-
up to £1,000,000 of life protection is currently available,
subject to age, health and underwriting criteria; - the maximum policy term is currently 50 years;
- the minimum age to take out a policy is 18;
-
the maximum age for taking out a policy is the day before the
applicant’s 70th birthday; - the policy must currently end before the insured person’s 90th birthday;
-
premiums are fixed for the policy term unless you choose to change
your cover; and -
Term Life policies have no cash or surrender value and provide no
life benefit simply because the insured person survives beyond the
policy term.
The amount available to an individual applicant can therefore be lower than
the headline maximum depending on underwriting and eligibility.
The appropriate amount should be based on the protection need rather than
simply choosing the maximum available amount.
Frequently asked questions
Should my life insurance equal my mortgage?
Not necessarily. Matching the current mortgage balance may be appropriate
where the principal aim is simply to provide money towards clearing that
debt. If your dependants would also need replacement income, childcare or
other financial support, the amount required could be higher. Existing
insurance and suitable assets could also reduce the amount of additional
cover needed.
Should I take life insurance for the original mortgage amount or current balance?
The current outstanding balance is normally the more relevant starting
point when assessing the liability today. Your wider protection objective,
mortgage type and future needs should also be considered.
How many times my salary should life insurance be?
There is no universal salary multiple that is appropriate for everybody.
A needs-based assessment considers your mortgage, debts, dependants,
household income, future financial requirements and existing protection.
Do I need more life insurance than my mortgage?
Potentially. If your family would still have significant financial needs
after the mortgage was repaid, you may want to consider protection beyond
the mortgage balance.
Can I have less life insurance than my mortgage?
Yes, depending on your circumstances and the amount an insurer is willing
to offer. You might already have savings, workplace cover or existing
insurance that reduces the additional amount required. However, if your
objective is to provide enough insurance to clear the mortgage, having
less cover than the outstanding liability could leave a shortfall.
Should I include other debts in my life insurance calculation?
Consider any debts or financial commitments that you would want your
household to have resources to deal with following your death. The legal
treatment of individual debts varies, so this should be viewed as part of
broader financial planning rather than an assumption that every debt
automatically transfers to a family member.
Should death-in-service reduce the amount of personal life insurance I buy?
It can form part of your existing protection and should be considered.
However, employment-based cover may end when you leave that employer,
so consider whether you want to depend entirely on employment-linked
protection.
Should savings reduce how much life insurance I need?
Potentially, if those savings are genuinely available for the financial
needs you are protecting. Do not automatically deduct money intended for
emergencies, education, retirement or another important purpose unless
you are comfortable changing that purpose.
How much life insurance should a couple with a joint mortgage have?
Assess the financial impact of each person’s death separately. The
mortgage liability may be the same, but lost income, workplace protection,
childcare requirements and other financial contributions can differ
substantially between partners.
Does a stay-at-home parent need life insurance?
They may have a significant protection need even without employment income.
Consider the financial cost of replacing childcare, caring responsibilities
and other unpaid services they provide to the household.
How much life insurance does a single parent need?
There is no standard amount. Consider the mortgage or housing costs,
children’s financial needs, future guardian arrangements, childcare,
education, existing assets, workplace benefits and how long financial
support may be required.
How much life insurance do I need for an interest-only mortgage?
Check the actual capital still outstanding. With an interest-only mortgage,
that amount may remain broadly unchanged despite years of monthly interest
payments. Level term insurance may be more closely aligned with a fixed
outstanding debt than protection that deliberately decreases.
Should I increase life insurance when I remortgage?
Review it if your borrowing increases, your mortgage term changes or your
repayment structure changes. Your existing life insurance does not normally
increase automatically when the mortgage changes.
Should I reduce life insurance after making mortgage overpayments?
Not automatically. A lower mortgage may reduce one part of your protection
need, but the policy might still be intended to provide money for family
living costs or other commitments. Review the complete purpose before
changing established protection.
What happens if the amount of life insurance I need is unaffordable?
Identify your most important financial risks and consider the amount,
duration and type of protection within a sustainable budget. Some protection
may still address important needs even if the idealised maximum amount is
unaffordable.
How often should I review life insurance?
Review it when significant financial or family circumstances change,
particularly after buying or moving home, remortgaging, having children,
changing employment, changing borrowing or materially increasing or
reducing your assets.
