Life Insurance Needs Calculator (DIME Method)

How this calculation works

The DIME method is a widely taught rule of thumb for sizing term life coverage: Debt + Income replacement + Mortgage + Education, less existing coverage and savings.

It is a starting point, not a recommendation — inflation, Social Security survivors benefits, and family-specific expenses change the ideal number.

How this Life Insurance Needs Calculator (DIME Method) works — 2026 guide

How much life insurance do you actually need? The DIME method gives a defensible starting answer in minutes: add your Debt (mortgage + loans), Income replacement (annual income × years your family would need it), and Education costs, then subtract existing savings and coverage. This calculator walks through each piece and returns a suggested term-life figure — the benchmark that insurance agents, planners, and financial forums all cite, but rarely make calculable.

How to use it in 3 steps

1. Enter your annual income, years to replace, mortgage, other debts, and college costs.
2. Subtract current savings and existing life insurance coverage.
3. Read your DIME-based life insurance need and the breakdown of each component.

Who this is for
