Life Insurance Calculator

The question behind life insurance is not how much a policy costs, but how much your household would need to keep its standard of living if your income stopped. This calculator estimates that number with the DIME method — Debt, Income, Mortgage, Education — the approach most commonly taught to insurance agents, then subtracts the cover you already hold so you see the real gap.

The method is deliberately simple and conservative. It asks you to add up your outstanding debts, replace a multiple of your annual income for a set number of years, pay off the remaining mortgage balance, and fund the education you intend to provide. From that total you subtract existing life insurance, employer group cover, and liquid savings. What remains is the amount a new policy would need to cover.

The income-multiple component deserves the most thought. A common rule of thumb is ten to fifteen times annual income, but that implicitly assumes a low interest rate and ignores inflation. If you prefer to think in years, replacing income for ten to twenty years gives a similar answer at today's rates. Either way, the goal is to give your survivors enough of a cushion to grieve and adjust without a financial crisis in the same year.

Two structural choices shape the cost. Term life insurance covers you for a set period, typically ten to thirty years, and is by far the cheapest way to buy a large death benefit. Permanent insurance, including whole and universal life, lasts your whole lifetime, builds cash value, and costs several times more for the same face amount. Most households with a mortgage and young children get the most protection per dollar from level term cover.

How the math works

DIME total = debts + (annual income × income-replacement years) + remaining mortgage + education costs.
Cover needed = DIME total − existing life insurance − liquid savings/other assets.
Income replacement of 10–15× annual income is a common default; more years gives a larger, safer buffer.
Term policies price on age, health, term length and face amount; the same benefit costs far less the younger and healthier you are.

Frequently asked questions

How much life insurance do I actually need?

A common starting point is ten to fifteen times your annual income, adjusted for debts, a mortgage and education costs. The DIME method used here adds those explicit needs, then subtracts existing cover and savings, which usually produces a more accurate figure than a flat multiple.

Is term or whole life insurance better?

For most families, level term cover is better value: it delivers the largest death benefit for the lowest premium over the years when children and a mortgage create the most risk. Whole life lasts your lifetime and builds cash value, but costs several times more for the same benefit.

How long should my term be?

Match it to the last obligation you want covered. If your youngest child is five and you plan to fund them to age 22, a 20-year term reaches that point. If the mortgage is the main risk, a term matching the remaining loan years is enough.

Do I count employer group life insurance?

Yes, as existing cover — but with caution. Group cover usually ends when the job does, and it is often only one or two times salary. Many advisers count it for the shortfall calculation but still recommend a personally owned policy for portability.

Does a stay-at-home parent need cover?

Often yes. Replacing childcare, household management and other unpaid work has a real cost, and a policy on a non-earning partner protects the family budget if that work must be purchased.

Will my premium rise over time?

With level term, no — the premium is fixed for the term. With annually renewable term, the price rises each year with your age, which is why level term is usually the better structure for long obligations.
