Life Insurance Calculator
Life insurance provides a tax-free lump sum to your loved ones if you die during the policy term — but working out how much cover you need, and roughly what it will cost, can feel daunting. Our life insurance calculator gives an instant premium estimate based on your age, desired cover amount, term, and health, so you know roughly what to expect before speaking to an adviser or insurer.

Working Out How Much Cover You Actually Need
A commonly used approach is the “DIME” method — adding up your outstanding Debt (including any mortgage), the years of Income your family would need replacing, the cost of your children’s future Education, and your funeral or other End-of-life expenses. For many people with a mortgage and dependants, this points towards cover in the region of several times their annual salary, though the right figure genuinely depends on your specific debts, family size, and how much financial cushion you want to leave behind.
Why Age Is the Biggest Factor in Your Premium
Life insurance premiums are based on actuarial mortality tables — statistical data on the likelihood of death at each age. Because this risk rises with age, particularly from the late 40s onwards, premiums increase steadily and then more steeply the older you are when you take out a policy. This is exactly why taking out life insurance sooner rather than later, even before you strictly “need” it, is usually cheaper over the life of the policy — locking in a lower rate based on your younger age at application.
Smoking Status: A Major Cost Driver
Insurers price smokers using entirely separate mortality tables, reflecting the well-documented higher health risks involved. A smoker can typically expect to pay more than double the premium of a non-smoker of the same age for identical cover — one of the largest single factors in the entire pricing model, larger even than most health conditions.
Level Term vs Decreasing Term for Life Insurance
Level term life insurance keeps your cover amount fixed for the whole policy, useful if you want the payout to cover more than just a reducing mortgage balance — perhaps replacing income for a number of years, or funding children’s education. Decreasing term cover, by contrast, is specifically designed to track a reducing repayment mortgage balance and is correspondingly cheaper — see our Mortgage Protection Insurance Calculator if that is your primary need.
A Worked Example
A 32-year-old non-smoker in good health taking out £300,000 of level term cover over 25 years might expect a premium in the region of £14–£18 a month. The same cover for a 50-year-old, all else equal, could cost three to four times as much, purely reflecting the higher underlying mortality risk at that age — underlining why arranging cover earlier in life is generally the more cost-effective approach.
Reviewing Your Cover Over Time
Life insurance needs are rarely static — a policy that made sense when you first took out a mortgage may no longer reflect your circumstances a decade later, particularly after having children, taking on a larger mortgage, or seeing your income and financial responsibilities grow. It is worth reviewing your cover at major life events — a house move, a new child, a significant pay rise — rather than assuming your original policy remains adequate indefinitely. Because premiums are generally cheaper the younger and healthier you are when you apply, it is also often more cost-effective to add a new, additional policy for extra cover as your needs grow, rather than cancelling an existing cheaper policy and starting again from scratch at an older age.
Frequently Asked Questions
Do I need a medical before getting life insurance?
Not always — many policies are arranged based on a detailed health questionnaire alone, though insurers may request a medical examination or GP report for higher cover amounts or where certain health conditions are disclosed.
Is life insurance the same as critical illness cover?
No — life insurance pays out on death within the term. Critical illness cover pays out on diagnosis of a specified serious illness, such as certain cancers, heart attack or stroke, while you are still alive. Some policies combine both.
Should I put my life insurance policy in trust?
Writing a policy in trust generally means the payout goes directly to your chosen beneficiaries, faster and outside your estate for Inheritance Tax purposes, rather than being subject to probate. It is worth discussing with your insurer or a financial adviser when you take out cover.
Can I get life insurance with a pre-existing health condition?
In many cases yes, though it may come with a higher premium or specific exclusions. Being upfront and accurate about your health during the application is essential — non-disclosure can invalidate a claim later.
