Life insurance

How much life insurance do you need?

This is different from the premium estimator — it answers “how much coverage”, not “how much will it cost”, using the widely-used DIME method.

Trust & methodology

Last reviewed: July 23, 2026

This tool provides a planning estimate for life insurance coverage using the DIME method — not a substitute for a licensed agent's needs analysis.

How to use this calculator

  • Enter income and years to replace

    How much you earn annually, and how many years dependents would need that income replaced.

  • Add debts and mortgage

    Non-mortgage debt (cards, loans) and your remaining mortgage balance.

  • Add education costs

    Number of children and an estimated education cost per child.

  • Subtract what you already have

    Existing life insurance and liquid savings reduce the net need.

Inputs used

  • Annual income and years of income to replace
  • Non-mortgage debt and remaining mortgage balance
  • Number of children and education cost per child
  • Existing life insurance coverage and liquid savings

Formula basis

  • Gross need = non-mortgage debt + (annual income × years to replace) + mortgage balance + (children × education cost per child)
  • Net need = gross need − existing life insurance − liquid savings

Assumptions and limits

  • Does not account for inflation, investment growth on the payout, or a family's changing needs over time
  • A widely-used starting-point method (DIME), not a substitute for a full financial needs analysis
  • Treats each input as a fixed, known amount rather than a range or probability

Frequently asked questions

DIME stands for Debt, Income, Mortgage, Education — four categories of financial obligation a life insurance payout is typically meant to cover. Adding them up and subtracting existing coverage and savings gives a reasonable starting estimate for how much coverage to buy.

A common range is 5–15 years, depending on how long dependents will rely on that income — for example, until the youngest child finishes school, or until a spouse's own retirement savings are on track.

No. This is a starting point for budgeting the conversation, not a substitute for advice tailored to your full financial picture, tax situation, and existing coverage.
