Level, decreasing or family income benefit: which life cover fits?

Checked 21 October 2026. 4 minute read.

Life insurance comes in several shapes, and the cheapest one isn't always the right one. The type you pick decides who is protected, and for how long.

The main types

TypeWhat it paysOften suits
Level termThe same lump sum whenever you die during the termInterest-only mortgages, general family cover
Decreasing termA lump sum that falls over the termA repayment mortgage, where the debt shrinks over time
Family income benefitA regular income from the date of death to the end of the termFamilies whose main worry is replacing a wage
Whole of lifeA lump sum whenever you die, with no end dateLeaving something certain behind, or paying an inheritance tax bill

Level term

The payout stays the same for the whole term. It is the simplest cover, and the easiest to explain to a family. It costs more than decreasing cover for the same starting amount, because the insurer's risk doesn't fall.

It fits a debt that doesn't shrink, such as an interest-only mortgage. It also works as general family cover.

Decreasing term

The sum assured falls year by year, usually in step with a repayment mortgage. It is generally the cheaper option, because the insurer pays out less the longer you live. There is a third version, increasing term, where the cover rises to keep up with inflation.

The match with the mortgage is the point. If the cover shrinks faster than your debt, there's a gap. If you want money left for the family as well as the mortgage, add a separate policy.

Family income benefit

This pays an income to your family, not a lump sum, usually from the date of death until the policy ends. A 20-year policy that you die in year 15 pays for five years.

It suits people whose worry is replacing a salary, not clearing one large debt. The cover period shortens as the term runs, which tends to match a family whose children are growing up. Check how the income is paid and whether it rises with inflation.

Whole of life

A whole of life policy pays out whenever you die, so it is certain to pay. Premiums are generally higher than for term cover, and it is less common. People use it to leave a guaranteed sum, or to pay an inheritance tax bill whenever it arises. Check whether the premiums are guaranteed or can be reviewed upwards.

Single or joint

A joint policy covers two people and usually pays out on the first death. A pair of single policies pays on each death. Joint cover is usually cheaper, but once it pays out the survivor may have no cover left. Which suits you depends on who relies on whom.

How much cover

Add up the debts that would still need paying, mainly the mortgage. Add the income your family would lose, for the years they would need it, and costs such as childcare. Then subtract what they would already have, such as savings, a partner's income and any death-in-service benefit from your employer.

Writing it in trust

A policy that isn't in trust pays into your estate. It can add to an inheritance tax bill, and your family may wait for confirmation before they receive it. Our guide to life insurance in trust in Scotland explains what to check, including the Scottish differences in trust law.

Life cover is one of three main kinds of protection. See also critical illness cover and income protection, which cover illness while you are alive.

Common questions

What is the difference between level term and decreasing term life insurance? +

Level term pays the same sum whenever you die during the policy. Decreasing term pays an amount that falls over the policy, usually in step with a repayment mortgage. Decreasing term costs less, because the insurer’s risk falls each year.

What is family income benefit? +

A policy that pays a regular income, not a lump sum, from the date of death until the end of the policy term. It suits families whose main worry is replacing a wage.

Is a life insurance payout taxable? +

It isn't subject to income tax. It can add to the value of your estate for inheritance tax unless the policy is written in trust.

How much cover do I need? +

Start with the debts that would still need paying, mainly a mortgage. Then add the income your family would lose, for the years they would need it, and costs such as childcare. Subtract what they would already have, such as savings and any death-in-service benefit.
