How to use this term life insurance calculator
- 1Outstanding debt: everything except your mortgage, which is handled separately below.
- 2Annual income to replace and years of income to replace: how much income support your family would need, and for how long — often until the youngest child is financially independent.
- 3Mortgage balance and future education costs: two of the largest single expenses a policy is commonly sized to cover.
- 4Existing coverage: any current life insurance or liquid savings that would offset the additional coverage needed.
Understanding your results
Additional coverage needed is your DIME total (debt, income replacement, mortgage, and education combined) minus what you already have covered — the amount of new term life insurance to shop for. This is a widely used starting estimate, not a guarantee of the exact right number for your family's specific situation.
The formula
Coverage = Debt + (Annual income × Years) + Mortgage + Education − Existing coverageEach DIME component addresses a specific financial gap: debt and mortgage represent lump sums that would need paying off, income replacement multiplies annual income by the number of years of support needed, and education is a lump-sum estimate for future costs. Summing all four gives the total need, which existing coverage and savings then offset.
A worked example
$15,000 in other debt, $70,000 income replaced for 10 years ($700,000), a $220,000 mortgage, and $60,000 in future education costs total $995,000 in DIME need. With $50,000 in existing coverage and savings, the additional coverage to shop for is about $945,000.
Notes for the UK, US and India
DIME is a widely used starting framework, not a precise personal calculation — factors like a stay-at-home parent's replacement-care costs, final expenses (funeral costs), or a shorter/longer income-replacement horizon than assumed here can shift the real number meaningfully. Many financial advisors also suggest a simpler 'income × 10' rule of thumb as a sanity check alongside DIME.
Frequently asked questions
Why term life instead of whole life insurance?+
Term life provides pure death-benefit coverage for a fixed period at a much lower cost than whole life (which combines insurance with a savings/investment component) — for most people, term life covering the years of highest financial responsibility (raising children, paying off a mortgage) is the more cost-effective choice.
Should I include a stay-at-home parent in this calculation?+
Yes, ideally — even without a salary, a stay-at-home parent provides real economic value (childcare, household management) that would cost real money to replace. Consider a separate policy sized to cover replacement childcare and household help.
Does this account for final expenses like a funeral?+
Not explicitly — consider adding a separate estimate (often $10,000-$15,000) for funeral and final expenses to the debt figure if you want this included in your total coverage estimate.
