Working out how much protection insurance you need can feel complicated.

You may want enough cover to protect your mortgage, replace lost income and support your family, but you probably do not want to pay for more protection than you realistically need.

The right amount of protection insurance depends on your income, debts, monthly expenses, dependants, savings and future plans.

In this guide, we explain how to calculate your overall protection insurance needs. We cover:

• Life insurance
• Critical illness cover
• Income protection insurance
• Mortgage and debt commitments
• Household expenses
• Financial support for children and other dependants
• Existing savings and workplace benefits

This is an umbrella guide designed to help UK families understand how different types of protection insurance can work together.

What Is Protection Insurance?

Protection insurance is designed to provide financial support if an unexpected event affects you or your family.

The three main types of personal protection insurance are life insurance, critical illness cover and income protection.

Life Insurance

Life insurance normally pays a lump sum if the insured person dies during the policy term.

The payment could help your family:

• Repay a mortgage
• Clear outstanding debts
• Cover everyday living expenses
• Pay childcare or education costs
• Meet funeral expenses
• Replace some of the income your household has lost

Life insurance may be particularly relevant if you have children, a partner who depends on your income or other financial responsibilities.

Critical Illness Cover

Critical illness cover normally pays a lump sum if you are diagnosed with a serious medical condition covered by the policy and meet the insurer’s definition.

The payment could be used to:

• Reduce or repay your mortgage
• Cover household bills
• Fund home adaptations
• Replace income during treatment or recovery
• Pay for additional childcare or care costs
• Support lifestyle changes following an illness

Not every illness is covered, and definitions can vary between insurers. You should always check the policy conditions, exclusions and claim definitions carefully.

Income Protection Insurance

Income protection insurance provides regular payments if illness or injury prevents you from working.

Depending on the policy, payments may continue until you:

• Return to work
• Reach the end of the claim period
• Reach retirement age
• Reach the end of the policy term

Income protection policies commonly replace approximately 50% to 65% of income, although the exact percentage and maximum benefit depend on the insurer and policy terms.

Many families combine life insurance, critical illness cover and income protection because each policy is designed to protect against a different financial risk.

Why Knowing How Much Protection Insurance You Need Matters

Buying too little protection insurance could leave your family with a financial shortfall during an already difficult time.

However, buying more cover than you need could result in unnecessarily high monthly premiums.

Finding the right balance can help ensure that:

• Your mortgage or rent can continue to be paid
• Loans and credit commitments can be managed
• Your family can maintain a reasonable standard of living
• Children’s costs can continue to be covered
• Future expenses can be planned for
• Your income is partly replaced if illness or injury stops you from working
• Your protection premiums remain affordable

There is no single amount of protection insurance that is suitable for every UK family.

Your cover should be based on your personal circumstances, financial priorities and available budget.

How to Calculate How Much Protection Insurance You Need

A protection insurance assessment should consider both your current financial commitments and the costs your family may face in the future.

1. Calculate Your Financial Commitments

Start by listing all your major financial responsibilities.

These may include:

• Outstanding mortgage balance
• Monthly rent payments
• Credit cards
• Personal loans
• Car finance
• Business borrowing
• Household bills
• Council tax
• Utilities
• Groceries
• Childcare costs
• School or university expenses
• Funeral expenses
• Other significant one-off costs

You should also consider whether your partner or family could continue meeting these commitments without your income.

Example: Sarah and John

Sarah and John have:

• A £150,000 outstanding mortgage
• Monthly household expenses of £2,000
• Two dependent children
• Ongoing childcare and education costs

They want to make sure that if either person dies, the mortgage can be repaid and their children can continue to receive financial support.

Their life insurance calculation may therefore include:

• £150,000 to repay the mortgage
• A separate amount to cover household expenses
• Additional money for childcare and education
• Any funeral or immediate family costs

The final amount would depend on their income, savings, workplace benefits and how many years of financial support they want to provide.

2. Consider Your Income and Future Plans

Your income is one of the most important factors when calculating your protection needs.

Consider:

• Your individual income
• Your partner’s income
• How much of your income is used for essential expenses
• Whether your household depends mainly on one income
• How long your family would need financial support
• Whether your income is likely to increase or decrease
• Future costs such as university fees
• Your planned retirement age
• Any maternity, parental or career breaks

You should also check what financial support is already available through your employer.

This might include:

• Employer sick pay
• Death-in-service benefits
• Workplace income protection
• Private medical insurance
• Existing life insurance
• Pension benefits

These benefits could reduce the amount of additional protection insurance you need. However, workplace benefits may end if you leave your employer, so they should be reviewed carefully.

Example: Mike

Mike earns £35,000 a year and has two young children.

His family depends on his income to cover the mortgage and household expenses.

Mike may want:

• Income protection to replace part of his earnings if he cannot work
• Life insurance to provide a lump sum for his family
• Critical illness cover to provide financial support following a covered diagnosis

He should calculate how much income his household would lose, what sick pay he receives from work and how long his savings would last.

3. Review Your Savings, Investments and Existing Cover

Protection insurance should be assessed alongside the financial resources you already have.

Review your:

• Emergency savings
• Cash savings
• Investments
• Pension benefits
• Existing life insurance
• Existing critical illness policies
• Workplace benefits
• Death-in-service cover
• Property or other assets

For example, a household with substantial accessible savings may need less short-term income protection than a household with no emergency fund.

However, relying entirely on savings may not be suitable if those savings are intended for retirement, education or another long-term goal.

4. Decide How Long Your Family Would Need Support

The amount of cover you need also depends on how long the financial support should last.

You might want protection until:

• Your mortgage is repaid
• Your children become financially independent
• Your children complete education
• Your partner reaches retirement
• You reach your planned retirement age
• A specific debt is cleared

A family with very young children may need a longer protection term than a couple whose mortgage is almost repaid and whose children are financially independent.

5. Determine Your Protection Priorities

Not every household will prioritise the same type of protection.

You may place greater importance on life insurance if:

• You have dependent children
• Your partner depends on your income
• You have a large mortgage
• You want to leave a financial legacy
• You have substantial personal or business debts

You may prioritise critical illness cover if:

• A serious illness would create additional expenses
• You would want to reduce your mortgage following a diagnosis
• Your household would need money during treatment or recovery
• You have limited savings

You may prioritise income protection if:

• Your household depends heavily on your monthly earnings
• You are self-employed
• Your employer provides limited sick pay
• You have regular mortgage, rent or debt payments
• You would struggle financially after several months without income

In many cases, a combination of policies can provide more complete financial protection than relying on one policy alone.

Quick Guide: How Much Protection Insurance Do You Need?

The following table provides a starting point. It is not a personalised recommendation, and the appropriate amount will depend on your individual circumstances.

Type of protection insurance	Possible starting point	What the cover may help with
Life insurance	Outstanding mortgage and debts, plus an amount for living expenses, dependants and future costs	Repaying debts and providing longer-term financial support for your family
Critical illness cover	An amount based on your mortgage, household expenses, recovery period and possible lifestyle adjustments	Managing financial pressure following a covered serious illness
Income protection insurance	Commonly around 50%–65% of income, subject to the insurer’s limits and policy terms	Replacing part of your income if illness or injury prevents you from working
Mortgage protection	An amount linked to the outstanding mortgage balance	Helping repay or reduce the mortgage following a covered event
Family income benefit	A regular annual or monthly amount based on your family’s expected expenses	Providing ongoing income to dependants during the remaining policy term

How Much Life Insurance Do I Need?

A common starting point is to calculate:

Mortgage + other debts + family living expenses + future costs − savings and existing cover

Your calculation might include:

• Outstanding mortgage balance
• Personal loans and credit cards
• Ten years of family living expenses
• Childcare costs
• School or university costs
• Funeral expenses
• Other financial commitments

However, using ten years of living expenses is only a general starting point. Some families may need support for a shorter period, while others may require protection until their children become financially independent.

Simple Life Insurance Example

Imagine your household has:

• £180,000 remaining on the mortgage
• £10,000 in other debts
• £25,000 of expected future education costs
• £100,000 needed for longer-term family support
• £20,000 in accessible savings

A basic calculation could be:

£180,000 + £10,000 + £25,000 + £100,000 − £20,000 = £295,000

This does not automatically mean £295,000 is the correct policy amount. It is an illustration of how different financial needs can be combined.

How Much Critical Illness Cover Do I Need?

Critical illness cover should be based on the financial impact a serious illness could have on your household.

Consider including enough to:

• Repay or reduce your mortgage
• Clear short-term debts
• Cover several months or years of expenses
• Pay for home adaptations
• Cover additional childcare
• Support your partner if they reduce their working hours
• Manage travel, treatment or recovery-related expenses

You do not necessarily need critical illness cover equal to your full life insurance amount.

Some people choose enough to clear the mortgage, while others select a smaller lump sum that fits their budget and covers their most important financial risks.

How Much Income Protection Do I Need?

Start by calculating your essential monthly expenses.

These may include:

• Mortgage or rent
• Council tax
• Utilities
• Groceries
• Transport
• Childcare
• Insurance
• Loan repayments
• Essential subscriptions
• Other regular household costs

You should then compare those expenses with:

• Your employer’s sick pay
• Statutory support you may qualify for
• Your partner’s income
• Your emergency savings
• Existing income protection benefits

Income protection usually replaces only part of your income rather than your full salary. MoneyHelper states that policies commonly pay around 50% to 65% of income.

The amount available will depend on your occupation, earnings, tax position, health, insurer and policy terms.

Real-Life Example: Jamie’s Protection Journey

Jamie is 38, married with two children and works as an electrician.

The family relies heavily on Jamie’s income.

Jamie’s financial position includes:

• £180,000 remaining on the mortgage
• 20 years remaining on the mortgage term
• Monthly household costs of £2,500
• £15,000 in savings
• Two financially dependent children

After reviewing the household’s needs, Jamie considers:

Type of cover	Example amount	Purpose
Life insurance	£250,000	To help clear the mortgage and provide additional support for the family
Critical illness cover	£100,000	To help manage the mortgage, household expenses and costs following a covered diagnosis
Income protection	60% of eligible income	To replace part of Jamie’s income if illness or injury prevents Jamie from working

Jamie selects income protection with a term lasting until retirement age 65, subject to the insurer’s terms and eligibility requirements.

This combination is intended to:

• Protect the mortgage
• Support ongoing household expenses
• Provide money following a covered critical illness
• Replace part of Jamie’s income during a valid claim

The figures are only an example. Another person with the same income could need a different amount depending on their debts, dependants, savings, health, occupation and budget.

Factors That Affect the Cost of Protection Insurance

The amount of protection insurance you choose can affect your premium, but it is not the only factor.

Insurers may also consider:

• Your age
• Your health
• Your medical history
• Your occupation
• Your smoking status
• Your lifestyle
• The amount of cover
• The length of the policy
• The type of cover
• The waiting or deferred period
• Whether the benefit increases over time
• Whether the policy covers one person or two people

Applications are subject to underwriting. The insurer may offer standard terms, increase the premium, apply an exclusion, postpone the application or decline cover depending on its assessment.

Important Things to Consider When Choosing Protection Insurance

Review Your Protection Regularly

Your protection needs can change when you:

• Get married
• Separate or divorce
• Buy a home
• Remortgage
• Have a child
• Change jobs
• Become self-employed
• Receive a significant pay increase
• Take on additional debt
• Move house
• Approach retirement

Reviewing your cover every couple of years, or after a major life event, can help ensure it still reflects your circumstances.

Check the Policy Definitions

This is particularly important for critical illness insurance.

A diagnosis alone may not always result in a payout. The condition must normally meet the exact definition stated in the policy.

Policies can differ in:

• The conditions covered
• The severity required
• Partial payment provisions
• Exclusions
• Survival periods
• Children’s cover
• Additional benefits

Understand the Income Protection Waiting Period

Income protection normally includes a deferred period.

This is the length of time you must be unable to work before payments begin.

Common deferred periods may include:

• Four weeks
• Eight weeks
• Thirteen weeks
• Twenty-six weeks
• Fifty-two weeks

A longer deferred period may reduce the premium, but you will need enough savings or employer sick pay to manage your expenses until the benefit starts.

Check the Definition of Incapacity

Income protection policies may assess your ability to work using definitions such as:

• Own occupation
• Suited occupation
• Any occupation

The definition can affect when a claim may be accepted, so it is important to understand how your policy defines incapacity.

Keep Premiums Affordable

The most comprehensive policy is not necessarily suitable if the premiums are difficult to maintain.

Choose a level of cover that:

• Addresses your most important risks
• Fits your monthly budget
• Can remain affordable over the policy term
• Complements your savings and workplace benefits

If your budget is limited, prioritising the largest financial risk may be more practical than trying to cover every possible outcome.

Common Protection Insurance Mistakes

Avoiding common mistakes can help you choose more suitable protection.

These mistakes may include:

• Covering only the mortgage and forgetting household expenses
• Assuming employer sick pay will continue indefinitely
• Relying entirely on savings
• Failing to account for childcare costs
• Ignoring a non-working partner’s financial contribution
• Choosing cover based only on the cheapest premium
• Not checking critical illness definitions
• Selecting an unsuitable income protection waiting period
• Forgetting to update cover after a major life event
• Cancelling existing protection before replacement cover is active
• Failing to provide complete and accurate information during the application

Frequently Asked Questions

Is Life Insurance the Same as Protection Insurance?

Life insurance is one type of protection insurance.

Protection insurance is a broader term that can include:

• Life insurance
• Critical illness cover
• Income protection
• Family income benefit
• Mortgage protection
• Business protection

Do I Need Life Insurance and Income Protection?

The two policies protect against different risks.

Life insurance normally pays following death during the policy term. Income protection provides regular payments if illness or injury prevents you from working.

A person may need one policy, both policies or a combination of several protection products.

Should My Life Insurance Cover My Full Mortgage?

Some homeowners choose enough life insurance to repay the full outstanding mortgage.

However, you should also consider:

• Other debts
• Household expenses
• Dependants
• Childcare
• Education costs
• Existing savings
• Your partner’s income
• Existing workplace benefits

Covering only the mortgage may still leave your family without enough money for everyday living costs.

How Often Should I Review My Protection Insurance?

Review your protection after major financial or family changes.

It can also be useful to review your policies every couple of years to check that:

• The cover amount remains suitable
• The policy term is still appropriate
• Beneficiary arrangements remain correct
• Your income protection benefit reflects your earnings
• Your premiums remain affordable

Can I Have More Than One Protection Policy?

You can hold more than one protection insurance policy.

For example, you could have:

• Life insurance linked to your mortgage
• Separate family life insurance
• Critical illness cover
• Income protection through a personal policy
• Death-in-service cover through your employer

However, income protection claims are normally subject to maximum benefit limits. Existing policies and employer benefits may be considered when calculating how much can be paid.

Does Protection Insurance Always Pay Out?

Protection insurance does not automatically pay in every situation.

A claim must meet the policy terms, definitions and eligibility requirements.

Claims may be affected by:

• Policy exclusions
• Inaccurate or incomplete application information
• The cause of the claim
• Whether premiums have been maintained
• Whether a critical illness meets the required definition
• Whether the policy is active
• Income protection benefit limits

Always read the policy documents carefully and answer application questions fully and accurately.

Not Sure How Much Protection Insurance You Need?

Calculating how much life insurance, critical illness cover or income protection you need can feel overwhelming.

Online calculators and general guides can provide a useful starting point, but they cannot fully assess your household’s individual circumstances.

A protection adviser can review:

• Your mortgage
• Your income
• Your debts
• Your household expenses
• Your savings
• Your dependants
• Your employer benefits
• Your future financial plans
• Your available monthly budget

At BSL Assured, we help UK families understand their protection insurance options without unnecessary jargon or pressure.

We explain how different policies work, what they may cover and how much protection could be appropriate for your circumstances.

• Add up your mortgage, debts and other financial commitments
• Calculate your essential monthly household expenses
• Decide how many years your family may need support
