The DIME Method: A Structured Approach

DIME (Debt + Income + Mortgage + Education) is the most commonly used structured framework for calculating life insurance needs: D = all non-mortgage debts + final expenses; I = annual income × years until youngest child is financially independent; M = remaining mortgage balance; E = estimated education costs for all children. Sum = your total coverage need, minus existing assets and insurance.

📊DIME Calculation for a 35-Year-Old Parent

D (Debt + final expenses): $45,000 + $20,000 = $65,000. I (Income replacement): $75,000 × 20 years = $1,500,000. M (Mortgage): $280,000. E (Education, 2 children): $200,000. Total DIME: $2,045,000. Less 401(k) ($120,000) and existing insurance ($100,000) = Net need: $1,825,000.

The Income Multiplier Method

A simpler approach: multiply annual income by 10–15. At $75,000 income: $750,000–$1,125,000 coverage. This rule of thumb is useful for quick estimates but misses mortgage debt, education needs, and the specific age of dependents. The DIME method is more accurate for people with complex situations.

How to Read the Calculator Output

The calculator’s output is your recommended death benefit — the face value of the policy to purchase. Compare this to existing coverage (employer group life, any policies you own). The gap is what you need to buy. Remember: most group life insurance (1–2× salary from employers) is drastically insufficient and non-portable (you lose it when you change jobs).
