How much life insurance do I need to protect my family?
How much life insurance you need will depend on your personal circumstances, such as whether you have dependents, a mortgage and/or any savings. As a simple starting point, many advisers suggest life insurance cover of around 10 times the salary of the highest earner in your household, then adjusting this up or down once you factor in your mortgage, other debts, regular bills, children, existing savings and any death-in-service benefit from work.
How does the Martin Lewis life cover 10 times salary rule work?
A common Martin Lewis life insurance rule of thumb is to multiply the highest household salary by 10 to get a rough cover amount. So a £45,000 income often points to about £450,000 of life insurance cover before you refine it for your own situation.
When could I need more life cover?
You may want a higher sum assured if you have a large mortgage, several children, plans to help with university fees, or a partner who relies heavily on your income to pay the bills.
When might I need less life insurance for my family?
A lower cover amount could be enough if your mortgage is small or already paid off, you have older children who are financially independent, or you hold significant savings and investments.
How and why should I compare life insurance quotes?
Different insurers price risk differently, especially for people with pre-existing medical conditions, high-risk jobs, or extreme sports. This is why comparing multiple life insurance quotes can help you get the right level of cover at the lowest available price for your age and health.

Our life insurance calculator is designed to give you a guide and suggest a figure for how much life cover you need. This figure will take into account a number of key factors and combine them to display the amount of life insurance that might work for you.
How to work out how much life insurance you need in the UK
Life insurance is there to protect the people who rely on you financially. If you pass away during the policy term, it pays out a tax-free lump sum, known as the sum assured, that your loved ones can use to clear debts, keep up with the mortgage and maintain their standard of living. There is no single right answer for how much life insurance you should have in the UK, but there are straightforward ways to reach a sensible figure that fits your budget.
A widely used guideline is to start with around 10 times the annual income of the main earner. That rough figure is designed to give your family a pot of money that can be drawn on over many years so they do not have to make big cutbacks at a time when they are already dealing with a bereavement. From there, you can adjust the number based on your mortgage balance, your children’s ages, any other debts, and any existing protection you already have in place.
The Martin Lewis 10 times salary life cover rule explained
The Martin Lewis 10 times salary rule is popular because it gives you a quick ballpark figure without needing a calculator. You simply take the highest gross annual salary in your household and multiply it by 10. If your partner earns £40,000 and you earn £30,000, you would usually base the calculation on £40,000, which suggests about £400,000 of cover for them.
This amount is aimed at offering enough of a financial cushion to pay off big debts and support day-to-day costs for several years. For example, if your family needed roughly £25,000 per year to cover bills, food, transport and other essentials, then £400,000 could, in theory, support them for a long period if managed carefully, particularly if your partner still has some income of their own.
However, you should see the 10 times salary rule as a starting point rather than a final answer. Some people will find that this figure is more than they realistically need, while others, especially those with young children or large mortgages, may decide that they need more. The right sum assured should feel reassuring and affordable, not excessive and costly.
A simple step-by-step method (income, debts and goals)
If you want to move beyond a rule of thumb, you can break the decision down into a few simple parts. This gives you a personalised figure and helps you understand what your policy is actually there to do.
1. Cover your mortgage or rent
Many people start by asking whether they would want their mortgage fully cleared if they died. If you have a repayment mortgage with £180,000 remaining, you might choose at least that amount of cover so your family could own the home outright and not face the risk of repossession. If you rent, you might instead think about how many years of rent you would want the policy to pay for, especially if your partner would struggle with this cost alone.
2. Clear other debts
Next, add in any other debts that you do not want to leave behind. This could include personal loans, overdrafts, car finance or credit cards. You do not have to cover every last pound, but many people feel more comfortable knowing that high-interest borrowing could be paid off so their loved ones are not chased by lenders at a difficult time.
3. Replace income for a period of time
Think about how much money your household would need each month without your income. List your regular outgoings, such as energy bills, food, transport, childcare and council tax, then subtract any income your partner would still receive, including their earnings and any benefits. The gap between the two is roughly what your life insurance payout would need to bridge.
Once you know that monthly gap, decide how long you want to provide support for. Some people choose until their youngest child turns 18 or 21, while others prefer a shorter period, such as 10 or 15 years, to give their partner breathing space to adjust. A broker or adviser can help you translate that income need into a realistic lump sum figure.
4. Add future goals and one-off costs
Many UK families like their life insurance to do more than just pay bills. You may want it to help with university costs, contribute to a house deposit for your children, or simply provide a small legacy. At the same time, do not forget immediate one-off costs like a funeral, which can easily run into several thousand pounds. Adding a reasonable allowance for these items can make your cover feel more complete.
5. Subtract savings and existing cover
Lastly, look at what you already have in place. This includes savings, investments and any existing life insurance policies, as well as death-in-service benefits through your employer. Many UK employers offer group life insurance worth around two to four times your salary. While this is a valuable benefit, it may not be portable if you change jobs, and it is rarely enough on its own. Subtracting these existing resources from your target figure stops you from paying for more cover than you actually need.
Example life insurance calculations for UK households
Sometimes it is easier to see how this works in practice. The table below shows three simple examples and how each family might approach their cover amount.
| Situation | Key details | Approximate cover needed |
|---|---|---|
| Couple with young children | Two children under 10, outstanding mortgage £220,000, main earner’s salary £40,000, partner part-time on £12,000 | £180,000 to clear mortgage plus around £200,000 to £300,000 to support living costs and childcare until children are grown, giving a total in the region of £380,000 to £480,000 |
| Single homeowner, no children | Age 35, mortgage £200,000, salary £30,000, wants to leave home to sibling but no dependants | Many people in this position might only cover their mortgage balance and funeral costs, perhaps choosing around £230,000 to £280,000 of cover |
| Older couple, mortgage nearly repaid | A couple in their 50s, small remaining mortgage of £50,000, grown-up children and healthy savings | They may feel comfortable with a relatively small policy focused on paying off the mortgage and funeral costs, maybe in the region of £50,000 to £80,000 |
These numbers are examples only, but they show how very different the right sum assured can be from one household to another. The important thing is to match your cover to your real financial responsibilities, rather than someone else’s target.
How long should your life insurance last?
Deciding the policy term is just as important as choosing the cover amount. In the UK, most people take out term life insurance, which runs for a specific number of years and only pays out if you die during that time. The length of the term should line up with the period when your family would really struggle without your income.
Linking cover to your mortgage
If your main concern is the mortgage, you might simply choose a term that matches the years left on your repayment mortgage. For example, if you have 25 years left, a 25-year term will make sure there will be money to clear the loan if you die early.
Linking cover to your children’s ages
Parents often pick a term that runs until their youngest child is financially independent, such as age 21 or 23. If your youngest is currently three years old, a 20-year term would provide protection until they are 23.
Cover up to retirement
Some people prefer their life insurance to run until their planned retirement age, so their partner has protection while they are still building up pensions and savings. For example, a 30-year-old might choose cover to age 65, which would mean a 35-year policy.
Types of life insurance and how they affect the amount you choose
The type of life insurance you buy in the UK can influence how much cover you go for and how much it costs each month. Broadly, there are three popular choices: level term, decreasing term and whole of life.
| Type of cover | How it works | Key benefits | Underwriting rules |
|---|---|---|---|
| Family life insurance (Level term) | A policy that runs for a set period and pays a fixed lump sum if you die during the term. | Useful for protecting an interest based mortgage, replacing lost income or covering family expenses. | Premiums and terms may be increase depending on your health, medical history, occupation, or sports. |
| Mortgage life insurance (Decreasing term) | Cover that runs for a set term, but the payout decreases over time, usually in line with a repayment mortgage. | A popular way to help make sure your mortgage is cleared if you die before it is fully repaid. | Underwriting is the same as family life insurance and premiums can also increase in the same way for pre-existing medical conditions, occupations, and sports. |
| Whole of life insurance | Provides lifelong cover and guarantees a payout whenever you die, as long as premiums are kept up. | Can fund a guaranteed inheritance or help with future costs such as funeral expenses or unpaid debts. | Usually more expensive than term cover and premiums may be higher for someone with a higher risk of claim. |
| Over 50 life insurance | Guaranteed acceptance policy for UK residents typically aged 50 to 85, with no medical questions or underwriting. | Ideal if you have been declined standard cover due to your health or occupation and you want to leave funds for funeral costs or a small gift. | Your medical history will not affect eligibility, although cover amounts are modest and there is usually a waiting period before full cover starts. |
How much does life insurance cost in the UK?
Many people are surprised at how affordable life insurance can be, especially if they arrange it while they are still relatively young and healthy. Premiums are based on factors such as your age, health, smoking status, cover amount, policy term and type of policy. As a rough guide, healthy non-smokers in their 20s or early 30s can often get a meaningful level of cover for just a few pounds a month.
Because every insurer has their own pricing approach, the same person can see quite a difference in quotes between providers. This is why comparing prices is so important. A broker that works with a wide panel of UK life insurance companies can help you find competitive rates without having to fill in multiple forms on different websites.
Why your personal circumstances matter more than averages
While rules of thumb and online examples are useful, your own circumstances are what really count. Someone with a high income but no dependants may not need a huge policy, while a family on a modest income with several young children might decide that a larger sum assured is essential. The key questions to ask yourself are:
- Who relies on my income or unpaid work, and for how long?
- What large financial commitments do I have, such as a mortgage or loans?
- What would I want my life insurance payout to achieve, in practical terms?
- How much can I realistically afford to pay in monthly premiums?
Using a broker to compare life insurance quotes
Shopping around for life insurance in the UK can feel time consuming, but you do not have to do it alone. A specialist broker can compare quotes from a range of leading insurers on your behalf, using one set of details, and then help you choose the option that best balances cover and cost.
Brokers are usually paid by the insurer, not by you, so there is typically no fee for getting quotes. This means you can benefit from their experience and market knowledge without adding to the cost of your policy. They can also explain the differences between policy types, show you how changing the term or cover amount affects the price, and help you complete the application accurately.
If you want to explore providers directly as well as through a broker, you can look at trusted UK comparison and advice sites such as MoneyHelper for impartial guidance, then use a broker or comparison service to check live prices.
Practical tips for choosing the right level of life insurance
- Start with a realistic budget: There is little point in arranging an ambitious level of cover if the premiums feel like a stretch every month. It is often better to have a slightly smaller policy you know you can keep going.
- Be honest on your application: Insurers rely on accurate information about your health, lifestyle and occupation. Being open does not automatically mean you will pay much more, but it does protect your loved ones from a future claim being turned down.
- Consider inflation: If you are taking a long-term policy, you might want to choose index-linked cover so that the sum assured rises in line with inflation. Alternatively, you can simply choose a slightly higher initial amount to give some extra cushion.
- Review your cover after big life events: Getting married, having a child, taking on a new mortgage or changing jobs are all good times to review whether your life insurance still fits.

FAQ’s – What you need to know about calculating life cover
Is the 10 times salary rule enough life insurance for everyone in the UK?
The 10 times salary rule is only a starting point and will not suit every UK household. It gives you a quick ballpark figure, but the right cover amount should reflect your specific situation, including your mortgage balance, other debts, the ages of your children, and how long your family would need financial support. Some people, such as those with young children or a large home loan, may need more than 10 times salary, while others with no dependants and low debts may be comfortable with less. It is usually best to treat the rule as a rough guide and then adjust the figure up or down based on your real financial responsibilities.
Should I base my life insurance on my salary or my mortgage?
Both your salary and your mortgage are important when working out how much life insurance you need. Your income affects how much financial support your family would lose if you died, which is where the 10 times salary rule can help. Your mortgage, on the other hand, is often a household’s biggest single debt, so many people want enough cover to clear it completely so that their loved ones can stay in the home without worrying about repayments. A simple approach is to start by deciding whether you want the mortgage fully repaid, then add an extra amount to replace part of your income for a number of years and to cover everyday living costs and future goals.
Do I still need life insurance if my employer offers death in service?
Employer death in service benefit is a valuable extra, but it rarely replaces the need for personal life insurance. Many UK employers provide a pay out of around two to four times your salary, which can certainly help your family, but it may not be enough on its own to clear a mortgage, pay off other debts and replace lost income for many years. It is also tied to your job, so you could lose the cover if you change employer or stop working. A common approach is to work out how much your family would ideally need in total, then subtract the value of any death in service benefit and savings so that you can choose a personal policy that fills the remaining gap.
How do I choose the right policy term for my life insurance?
The right policy term depends on how long your loved ones would struggle financially without your support. Many people in the UK choose a term that lines up with major commitments. If your priority is the mortgage, you might match the term to the years left on your repayment loan. Parents often pick a term that lasts until their youngest child is financially independent, for example age 21 or 23. Others prefer cover up to their planned retirement age, so that there is protection while pensions and savings are still building. Thinking about when your big expenses will naturally fall away can help you choose a term that is long enough without paying for cover you no longer need.
How can I keep UK life insurance premiums affordable while still having useful cover?
There are several ways to balance meaningful protection with a realistic budget. First, decide what is essential to cover, such as clearing the mortgage and providing a basic income cushion, rather than aiming for a very large sum that feels unaffordable. Choosing decreasing term insurance just for the mortgage can reduce costs compared with level term cover, because the payout falls as the loan is repaid. You can also adjust the policy term and sum assured to see how these changes affect the premium. Arranging cover while you are younger and in good health usually keeps prices lower, and comparing quotes through a specialist broker can help you find competitive deals without paying a fee. Whatever you choose, it is generally better to have a modest policy you can maintain comfortably than a higher level of cover that strains your budget.
Making life insurance easy and affordable
Life insurance can feel complex, but the basics are straightforward once you focus on what you are protecting. Add up the big commitments such as your mortgage, think about how much your family would need each month without you, and allow for future milestones you would like to support. Use the 10 times salary rule as a quick sense check rather than a strict answer, and then shape the final number to fit your own life.
Life insurance can provide a reassuring financial safety net for your loved ones if the worst were to happen to you. Whether you choose to arrange cover directly or through a broker, the most important step is simply getting started so that the people who matter most to you have protection in place if they ever need it.
