An educational estimate, not personalized financial advice. Your actual needs depend on factors this simplified method doesn't capture - consider speaking with a licensed financial advisor for your specific situation.

The formula

Coverage need = Debt + (Annual Income x Years of Replacement) + Mortgage + Education - Existing Coverage & Savings D = Debts (excluding mortgage) I = Income replacement (annual income x years your family would need support) M = Remaining mortgage balance E = Education costs for children
Example

$40,000 in debt, $75,000 income replaced for 10 years ($750,000), a $280,000 mortgage, and a $100,000 education fund, minus $50,000 in existing coverage and savings: total coverage need of $1,120,000.

Step-by-step guide

  1. Add up your non-mortgage debts - credit cards, car loans, and any student loans not forgiven upon death.
  2. Estimate income replacement - your annual income multiplied by however many years your family would need that support (often until the youngest child becomes independent).
  3. Add your mortgage balance and education fund goal, then subtract any existing life insurance and liquid savings, to get your estimated coverage gap.

Why DIME beats a simple "10x income" rule

A common shortcut is "buy coverage worth 10x your annual income," which is easy to remember but ignores your actual financial picture. Someone with a paid-off house and no debt needs meaningfully less coverage than someone with a large mortgage and young children, even at the same income - the flat multiple treats both cases identically. DIME accounts for your specific debts, your actual mortgage balance, real education cost goals, and what coverage or savings you already have, producing a number tailored to your household rather than a generic multiple of salary.

Common mistakes

Forgetting to subtract existing coverage and savings - if you already have some life insurance through work or personal savings, your remaining coverage gap is smaller than the full DIME total.
Not revisiting the number after major life events - marriage, a new child, a home purchase, or a significant salary change all shift your real coverage need, so it's worth recalculating every few years rather than setting it once.

Frequently asked questions

How many years of income replacement should I use?

A common approach is to use the number of years until your youngest child becomes financially independent, though some people choose a shorter window if there's a working spouse, or a longer one for extra security. There's no universal right answer - it depends on your family's specific situation.

Does the DIME method account for everything my family might need?

Not entirely - it's a solid, widely-used starting framework, but doesn't automatically account for things like ongoing childcare costs, a stay-at-home parent's replacement value, or your surviving spouse's own retirement savings needs. Many people add a cushion on top of the DIME total for this reason.

Should I buy whole life or term life insurance to cover this amount?

This calculator estimates how much coverage you need, not which product to buy. Term life insurance is generally significantly cheaper than whole life for the same death benefit, which is why many financial planners suggest term coverage matched to the years you actually need protection (like until a mortgage is paid off or kids are grown).
