More on choosing the right cover
How the Calculation Works
The calculator uses a widely-used approach sometimes called DIME — Debts, Income, Mortgage, Education. In plain terms, it adds up what you'd want to protect and subtracts what you've already got:
➕ What you'd want to cover
- Outstanding mortgage
- Other debts (loans, cards)
- Income replacement (annual income × years)
- Children's costs (childcare, education)
- Funeral & final expenses
➖ Cover you already have
- Existing life insurance
- Employer death-in-service (often 3–4× salary)
- Savings & assets you'd use
The result is an estimated shortfall — a starting point for the sum assured you might consider. It's deliberately simple: it doesn't model inflation, tax nuances or your whole financial plan, so treat it as a guide, not a final figure.
How Much Life Insurance Do You Actually Need?
There's no single right answer — it depends on your circumstances. Two common approaches:
- Multiple of income: a quick rule of thumb is around 10× your annual salary. Fast, but rough.
- Needs-based (this calculator): add up your actual responsibilities and subtract existing cover. More tailored, and usually more accurate.
If you're mainly covering a mortgage, your need may reduce over time (a repayment mortgage shrinks), which is where decreasing term cover fits. If you're replacing family income, a level amount often makes more sense. For the different policy shapes, see term life insurance and whole of life.
What Affects the Amount You Need
- Dependants: children or a partner reliant on your income push the figure up
- Mortgage size & term: usually the biggest single component
- Existing cover: employer death-in-service can cover a chunk already
- Life stage: needs differ for parents, couples, the single, self-employed and over-50s
- How long cover should last: see how long to get cover for
What About the Cost?
💡 This tool estimates cover, not price
The calculator works out how much cover you might need — the sum assured — not the monthly premium. The price of a policy depends on your age, health, whether you smoke, the cover amount and the term, and only an insurer can give an accurate figure. Any general price ranges you see online are illustrative, not a quote for you. See what affects term life cost, or how cover works for smokers.
Generally, term life is the cheapest cover and buying younger and healthier locks in a lower premium. To get real numbers, get a personalised quote and compare — see the best UK life insurers.

Frequently Asked Questions
How does a life insurance calculator work?
A life insurance calculator estimates how much cover you might need by adding up your financial responsibilities — such as your outstanding mortgage, other debts, income you'd want to replace, and future costs like childcare — then subtracting any cover you already have, for example death-in-service from an employer. The result is a guide figure for the lump sum that could protect your family. It's an estimate for guidance, not a personal recommendation.
How much life insurance do I need?
A common rule of thumb is around 10 times your annual income, but it's better to add up what you're actually protecting: your mortgage and debts, the income your family would need for a set number of years, and costs like childcare and education, minus any existing cover. The right figure depends on your circumstances, so treat any calculator result as a starting point and consider advice from a regulated adviser.
Is this life insurance calculator accurate?
It gives a reasonable estimate based on the figures you enter, but it's a simplified guide, not a precise or personalised calculation. It doesn't account for every factor, such as inflation, changing circumstances or your full financial plan. Use it to get a sense of the cover you might need, then confirm the right amount and policy with a personalised quote or a regulated financial adviser.
Does the calculator tell me how much my policy will cost?
No. This calculator estimates how much cover you may need — the sum assured — not the monthly premium. The price of a policy depends on your age, health, whether you smoke, the cover amount and the term, and only an insurer can give an accurate quote. Any premium figures you see quoted generally are illustrative market ranges, not a quote for you.
Should I include my partner's income?
It depends on how your household relies on each income. Many couples calculate cover for each person based on the income and responsibilities that would need protecting if that person died. If you share a mortgage, you might consider a joint policy or two single policies. A calculator can help you estimate each person's need separately, which is often more accurate than a single combined figure.
Does this calculator store my information?
No. This calculator runs entirely in your browser and does not send, save or share any of the figures you enter. Nothing is stored once you leave the page. It's designed purely to give you a private, instant estimate of the cover you might need, with no personal data collected.
Is a life insurance calculator financial advice?
No. A calculator provides general guidance and estimates based on the numbers you enter — it is not regulated financial advice and not a personal recommendation to buy any particular policy. For advice tailored to your circumstances, speak to an FCA-regulated financial adviser, who can recommend a suitable amount, type and provider of cover.
