What is the life insurance needs calculator?

In short

Most financial advisors recommend life insurance equal to 10–12× your annual income, but the DIME method (Debt, Income, Mortgage, Education) gives a more precise figure. On an $80,000 income with a $250,000 mortgage, 20 years of income replacement, and $50,000 in education costs, total coverage needed is roughly $1,685,000 before existing assets.

Uses the DIME method to calculate exactly how much life insurance you need — factoring in income replacement, mortgage, other debts, final expenses, and education costs, minus assets you already have.

How to use this calculator

  1. 1Enter your annual income and how many years your family would need income replacement.
  2. 2Add your mortgage balance, other debts, final expense estimate, and education fund goal.
  3. 3Enter existing savings and any life insurance already in force.
  4. 4The calculator shows your total coverage gap.

The formula

TN=(income×years)+mortgage+debts+education
CN=max(0,TN−EA)
TN = IR + D; CN = max(0, TN − EA)
IR
— Income replacement = income × years
D
— Debts = mortgage + other debts + final expenses + education
TN
— Total needs = IR + D
EA
— Existing assets = savings + current insurance
CN
— Coverage needed = max(0, TN − EA)

Worked example

The scenario

$80,000 income × 20 years + $250,000 mortgage + $20,000 debts + $15,000 final expenses + $50,000 education − $150,000 existing assets.

gives

The result

Total needs: $1,935,000. Coverage needed: $1,785,000.

Common use cases

  • Parents with young children determining term life insurance needs.
  • Homeowners with a mortgage calculating family protection coverage.
  • Anyone reviewing existing life insurance to check if it's adequate.

Limitations & assumptions

  • Does not account for Social Security survivor benefits, which can reduce the coverage needed.
  • Does not model inflation — income replacement in 20 years may need adjustment for purchasing power.
  • The DIME method is a starting point — individual circumstances may require more or less coverage.

Frequently asked questions

The DIME method (Debt + Income + Mortgage + Education minus existing assets) gives a precise figure. A common rule of thumb is 10–12× annual income, but DIME accounts for your specific debts and goals.
