How much life insurance do I need?
A common starting point is 10 to 15 times your annual income, refined using the DIME method: add up your outstanding Debt, the Income you want to replace for a set number of years, your remaining Mortgage balance, and future Education costs for any children, then subtract existing savings and coverage. The right number depends on your specific dependents, debts, and goals more than any single rule of thumb.
- The income-multiple rule of thumb (commonly 10-15 times annual income) is a fast starting estimate, not a precise calculation tailored to your situation.
- The DIME method — Debt, Income replacement, Mortgage, Education — adds up your actual financial obligations for a more specific number.
- Existing coverage (employer-provided group life insurance, other personal policies) and liquid savings should be subtracted from your calculated need, not ignored.
- Your needed coverage amount typically changes over time as debts are paid down and children grow up, which is why many people choose term lengths matched to a specific need (like the years remaining on a mortgage) rather than a single number for life.
The Quick Estimate: Income Multiples
A More Precise Method: DIME
Why Your Number Changes Over Time
Case Study: A DIME Calculation for a Young Family
Scenario: A couple with a young child and a 25-year mortgage wanted a specific coverage number rather than relying on a generic income-multiple rule of thumb.
Resolution & Judicial Outcome: Using the DIME method, they added their remaining mortgage balance, an estimated $18,000 for their child's future four-year education, 15 years of income replacement, and $12,000 in other debt, then subtracted their existing retirement savings and a small employer-provided group life policy, arriving at a specific 20-year term coverage amount tailored to their actual obligations.
What You Should Do: Step-by-Step Action Plan
Critical Mistakes to Avoid
- Relying solely on a generic income-multiple rule without adjusting for your specific debts and dependents.
- Forgetting to subtract existing employer-provided group life coverage from your calculated need.
- Assuming you need the same coverage amount for your entire life rather than matching term length to a specific financial timeline.
- Not accounting for future education costs for children when calculating total need.
