How much life insurance do you need?

The amount of life insurance you need depends on what financial obligations your death would leave behind. A solid starting point is to add up your debts, estimate how many years of income your family would need to replace, and factor in future expenses like education. The result is a coverage amount that provides real protection, not just a round number.

A simple formula

One widely used approach is the DIME method:

  • D – Debt: Total all outstanding debts—mortgage balance, car loans, student loans, credit cards, and any other obligations.
  • I – Income: Multiply your annual income by the number of years your family would need it. If you earn $80,000 and your youngest child is 5, you might want 15 to 20 years of income replacement.
  • M – Mortgage: If not already included in debt, add the remaining mortgage balance so your family can stay in the home.
  • E – Education: Estimate tuition costs for each child. A rough figure for four years of public university is $100,000 to $120,000 per child; private schools cost significantly more.

Add these together, then subtract existing savings, investments, and any employer-provided life insurance. The remainder is your coverage gap.

Rules of thumb vs. real calculations

The "10 times your income" rule of thumb is a quick shortcut, but it does not account for debt levels, the number of children, a spouse's earning potential, or existing savings. Two people earning the same salary can have very different coverage needs. A detailed calculation always produces a more accurate number.

Factors that increase the amount

  • Stay-at-home spouse: Replace the economic value of childcare, housekeeping, and other services.
  • Special needs dependent: Lifelong care costs can require significantly more coverage.
  • Business obligations: Key-person or buy-sell coverage adds to the total.

Factors that reduce the amount

  • Existing savings and investments: A healthy 401(k) or investment portfolio offsets the coverage needed.
  • Employer life insurance: Group coverage through work reduces your gap, though it usually is not enough on its own.
  • Spouse's income: A working spouse who can cover some expenses alone reduces the coverage target.

What Truscott recommends

Getting the amount right matters more than getting the cheapest premium. Too little coverage leaves your family exposed; too much wastes money on premiums you do not need. A Truscott coverage review walks through your specific debts, income, and goals to land on a number that makes sense. Reach out for a personalized assessment.
