Life Insurance Need is the amount of life-insurance capital a household may need if an income earner dies. Life insurance need is a protection-planning question, not a prediction of a family's future. The DIME method gives a transparent starting point by adding debts, income replacement, mortgage obligations, and education costs for dependants. It turns a vague question — “How much cover is enough?” — into a list of obligations that can be checked, updated, and discussed with a qualified adviser.
Enter the annual income you want to replace, the number of replacement years, outstanding non-mortgage debt, the remaining mortgage balance, estimated education costs, and existing life cover. Keep each amount on the same currency basis. Existing cover can include an employer policy, but check whether it would continue after changing jobs. For broader household context, see Retirement Calculator; the assumptions there are different, so do not combine the two results without checking their time period and scope.
DIME stands for Debt, Income, Mortgage, and Education. Debt includes balances that would otherwise fall to the household. Income replacement is a planning allowance rather than a promise to recreate every future pay rise. Mortgage means the balance that would need to be cleared or serviced. Education is an estimate for the support you want to provide, not a fixed tuition invoice. The related Mortgage Calculator page is useful when this distinction affects a household budget, while Emergency Fund Calculator covers the next comparison boundary.
Insurance arithmetic is only as reliable as its boundary. Record whether a number is a premium, eligible claim amount, allowed amount, deductible, fixed copay, coinsurance share, limit, or maximum. Keep the policy year and the currency beside the result. A clean record makes it easier to challenge a surprising claim and to repeat a comparison when the policy renews.
Do not enter a billed charge when the plan uses a negotiated or allowed amount unless you deliberately want to model the higher charge. If a field does not match the policy wording, pause and ask the insurer or a qualified adviser rather than forcing a value into the nearest-looking box.
DIME need = outstanding debt + (annual income × replacement years) + mortgage balance + education costs. Additional need = max(0, DIME need − existing coverage).
Suppose a household enters £25,000 of debt, £60,000 income, 10 replacement years, a £180,000 mortgage, £50,000 education costs, and £100,000 existing cover. The DIME need is £855,000 and the additional gap is £755,000. That is a planning illustration, not a recommended policy size.
The simple DIME total does not discount future income to present value, subtract liquid assets, model tax, include childcare, or decide whether a mortgage should be repaid. Inflation and investment returns can materially change the capital required. A needs analysis should also consider the survivor's housing, care, work, and benefit position. This is why the calculator keeps its inputs visible instead of presenting a single unexplained “insurance cost” number. The output is a transparent scenario that can be audited, not a claim adjudication or a policy quote.
When a policy has more than one cost-sharing stage, calculate in order: identify the covered amount, apply any deductible that remains, apply a fixed copay or percentage where the schedule requires it, then check the relevant limit or maximum. Reversing that order can make a patient share look artificially small or make a coverage limit appear larger than it is.
The first result is the gross capital target. The gap result is more useful when reviewing policies because it shows the shortfall after existing cover. A household with savings, investments, a second income, or a partner who would not need the full income replacement period may need a different target.
Run a conservative and a lower-cost scenario. Shorter replacement years may fit a household whose expenses fall as children become independent; longer cover may be reasonable when a survivor has limited earning capacity. Compare the gap with the policy's term, exclusions, indexation, and beneficiary arrangements before treating the number as a purchase instruction.
A result that looks favourable under one scenario can change when usage, renewal pricing, family composition, provider network, or an exclusion changes. Test the variable you are least certain about first. For a comparison, keep the scenario constant across every plan; for a protection decision, compare the likely cash exposure with the amount you could access without selling an asset or missing a bill.
