Whole of Life Insurance Calculator

Indicative Whole of Life Premium Rates by Age — UK 2025/26

The calculator above is built on a transparent age-band rate table expressed as an indicative monthly cost per £1,000 of guaranteed whole of life cover for a healthy non-smoker. Rates rise steeply with age because whole of life cover is certain to pay out. Smoker rates are typically 1.5–2× higher; reviewable premiums start lower but can increase at review.

Whole of Life Insurance in the UK — A Complete Guide

Whole of life insurance (often called "whole life" or "whole of life cover") is a protection policy that pays out a guaranteed lump sum whenever you die, with no fixed end date. Unlike term insurance — which only pays out if you die within a set period such as 20 or 25 years — a whole of life policy is designed to last for the rest of your life, which means it is certain to pay a claim at some point. That certainty is exactly why it costs more than term cover, and why estimating the premium accurately matters before you commit to decades of payments.

This page explains how our whole of life insurance calculator works, walks through a worked example with real numbers, and sets out the rules and factors that shape your premium for the 2025/26 tax year. It is written for UK residents and references guidance from the Association of British Insurers (ABI), the Financial Conduct Authority (FCA) and GOV.UK.

How the calculator works

Our estimator does not pull live quotes from insurers — no honest calculator can, because real premiums are individually underwritten on the basis of your full medical history, occupation, family history and lifestyle. Instead, it uses a transparent rate table: an indicative monthly cost per £1,000 of cover for each age band, derived from published market averages and the well-understood relationship between age and mortality risk. The calculation has four steps:

1. Find the base rate. The calculator selects an age-band rate (a low and a high figure in £ per £1,000 of cover) based on your age. The bands climb steeply with age because the older you are, the sooner a guaranteed payout is statistically expected, so insurers charge more.
2. Scale by the sum assured. The per-£1,000 rate is multiplied by your chosen cover divided by 1,000. So £100,000 of cover uses the rate × 100.
3. Apply the smoker loading. If you smoke or have used nicotine in the last 12 months, the premium is multiplied by roughly 1.5× at the low end and 1.8× at the high end, reflecting the higher mortality risk insurers price in.
4. Apply the premium-basis adjustment. If you choose a reviewable basis, the starting premium is reduced by around 15–20% to reflect that reviewable policies are cheaper at outset — with a clear warning that the premium can rise at review.

The result is presented as a low–high indicative monthly range rather than a single figure, because genuine premiums vary widely between insurers and depend on factors a calculator cannot see. The range is deliberately honest: think of it as the ballpark you should expect to see when you obtain real quotes.

Worked example

Suppose Priya is a 55-year-old non-smoker in good health who wants £100,000 of guaranteed whole of life cover to leave a tax-efficient legacy and meet an expected inheritance tax bill. Here is how the calculator arrives at her indicative premium:

• Age band 50–59: indicative rate of £0.45–£0.75 per £1,000 of cover per month.
• Sum assured of £100,000: that is 100 units of £1,000, so the monthly cost is 100 × £0.45 to 100 × £0.75 = £45 to £75 per month.
• Non-smoker: no smoker loading applied.
• Guaranteed basis: no reduction applied — the premium is fixed for life.

Priya's indicative range is therefore £45–£75 per month for guaranteed cover. If Priya smoked, the calculator would apply the smoker loading and the range would rise to roughly £68–£135 per month. If she chose a reviewable basis instead of guaranteed, her starting premium would be around 15–20% lower (roughly £36–£64 per month for a non-smoker), but the insurer could increase it at the next review. These figures align with the market average of about £102 per month at £128,000 of cover, scaled down for her lower sum assured.

Whole of life vs term life — which do you actually need?

This is the single most important decision, because choosing the wrong product can cost thousands of pounds. The rule of thumb is simple: match the product to the duration of the need.

• Temporary need → term insurance. If you are protecting a repayment mortgage, or replacing income only until your children are independent, the need disappears after a fixed period. Level or decreasing term insurance is far cheaper for these purposes — often a fraction of the cost of whole of life — because the policy may never pay out.
• Permanent need → whole of life insurance. If the need will still exist whenever you die — leaving a guaranteed inheritance, covering an expected inheritance tax bill, providing for a dependant with a lifelong disability, or meeting funeral costs — then whole of life is the appropriate product, because it is guaranteed to pay out.

If you are simply trying to work out how much cover you need before deciding on a product, start with our life insurance cover calculator, which uses the 10× salary rule and a needs-based DIME assessment.

Guaranteed vs reviewable premiums

Whole of life policies come on one of two premium bases, and understanding the difference is essential because it affects the cost over your whole lifetime:

Guaranteed premiums are fixed at outset and never change, no matter how long you live or what happens to investment markets. You know exactly what you will pay every month for the rest of your life. This certainty is valuable, especially in retirement on a fixed income, and is why most advisers recommend guaranteed premiums for buyers who want peace of mind.

Reviewable premiums start lower — commonly around 10–25% cheaper at outset — but the insurer reviews them at set intervals (typically every 5 or 10 years) and can increase them based on investment returns and claims experience. At early reviews the increase may be modest, but at later reviews, when you are older, premiums can rise sharply and in some cases become unaffordable, forcing people to reduce cover or lapse the policy at the very time they most need it. The FCA expects insurers to communicate review outcomes clearly, but the risk sits with you. Our calculator shows a reviewable starting premium roughly 15–20% below the guaranteed figure, with this warning attached.

What changes your premium

Several factors determine the premium an insurer will actually offer you:

• Age: the biggest single factor. Premiums are based largely on your age and expected mortality when the policy starts, which is why cover taken out at 50 is much cheaper per month than the same cover started at 65.
• Sum assured: the higher the guaranteed payout, the higher the premium, broadly in proportion.
• Smoker status: smokers and recent nicotine users typically pay around 1.5–2× the premium of non-smokers. Stopping for a continuous 12 months usually allows you to re-apply at non-smoker rates.
• Health and lifestyle: your weight (BMI), medical history, family history, alcohol consumption and any hazardous hobbies or occupations all feed into underwriting.
• Premium basis: guaranteed vs reviewable, as explained above.
• Gender — no longer a factor. Under the EU Gender Directive, which has applied to all new UK insurance contracts since 21 December 2012, insurers must use unisex pricing. Your premium does not depend on whether you are male or female, so our calculator deliberately uses unisex rates.

Whole of life insurance and inheritance tax

One of the most common reasons to buy whole of life cover is inheritance tax (IHT) planning. IHT is normally charged at 40% on the value of an estate above the available nil-rate bands. For 2025/26 the standard nil-rate band is £325,000, with an additional residence nil-rate band of up to £175,000 where a main home is passed to direct descendants — figures and rules are set out on GOV.UK. By taking out a whole of life policy for the expected IHT liability and writing it in trust, the payout falls outside your estate and gives your beneficiaries a guaranteed lump sum to settle the tax bill, rather than having to sell the family home or other assets in a hurry.

Because such a policy is certain to pay out, premiums are higher than term cover, but for larger estates the cover can be very cost-effective relative to the tax it covers. You can estimate a potential liability with our inheritance tax calculator. Trust arrangements should be set up with the help of a solicitor and an FCA-regulated financial adviser.

Over-50s guaranteed acceptance plans

A simplified form of whole of life cover is the over-50s guaranteed acceptance plan, widely advertised in the UK. These accept applicants aged roughly 50–80 with no medical questions, pay a fixed lump sum (often modest — typically £1,000 to £25,000) and are mainly used to cover funeral costs. They usually carry a 12–24 month initial period during which only premiums (sometimes plus interest) are returned on death from natural causes. They can be good value for older applicants in poor health who would struggle with full underwriting, but for healthy applicants a fully underwritten whole of life policy often provides more cover per pound. If this is your situation, see our dedicated over-50s life insurance calculator.

Should you add critical illness cover?

Whole of life insurance pays out on death. It does not pay out if you are diagnosed with a serious illness but survive. Many people pair life cover with critical illness cover, which pays a lump sum on diagnosis of a specified serious condition such as cancer, a heart attack or a stroke. Adding critical illness increases the premium, but it protects against a far more likely event than death during your working years. Whether to combine the two depends on your circumstances and budget — an FCA-regulated adviser can model the options.
