DIME

The DIME method is a financial planning framework used to calculate life insurance coverage needs systematically. DIME stands for the four components of financial obligation that a working adult's income typically covers:

• D — Debt: All outstanding liabilities other than the mortgage — credit cards, car loans, student loans, personal loans, medical debt. If you died today, these would need to be paid off to prevent financial burden on your family.

• I — Income replacement: Your annual income multiplied by the number of years your family would need replacement income. This is typically the largest component — it accounts for the ongoing living expenses your salary covers until your youngest child is financially independent.

• M — Mortgage: The remaining outstanding balance on your home loan. The goal is that the death benefit could fully retire the mortgage, eliminating housing debt for surviving family members.

• E — Education: Estimated future cost of college or vocational training for all children. A reasonable planning estimate is $150,000–$250,000 per child for a 4-year degree at a public university in today's dollars.

The DIME calculation:

Total Need = D + I + M + E

Net Coverage Needed = Total Need − Liquid Assets

Coverage Gap = Net Coverage Needed − Existing Life Insurance

A positive coverage gap means you are underinsured. Use the Life Insurance Needs Calculator to run the full DIME calculation with your actual numbers, then take the result to the Term Life Insurance Cost Estimator to find the annual premium for that coverage amount.

Total insurance need (DIME):

Total Need = Outstanding Debts + (Annual Income × Years of Replacement) + Remaining Mortgage + Education Costs + Final Expenses

Net coverage needed:

Net Coverage = max(0, Total Need − Liquid Assets)

Coverage gap:

Coverage Gap = Net Coverage − Existing Life Insurance

Positive = underinsured (buy more) · Negative = over-insured (coverage surplus)

Applicant: 38 years old · Spouse: non-working · Youngest child: age 6 · Years to replace income: 20

Annual income: $90,000

DIME breakdown:

• Debt (car loan + credit cards): $35,000
• Income (20 years): $90,000 × 20 = $1,800,000
• Mortgage (remaining balance): $380,000
• Education (two children): $200,000 × 2 = $400,000
• Final expenses: $20,000

Total DIME need: $35,000 + $1,800,000 + $380,000 + $400,000 + $20,000 = $2,635,000

Existing assets to subtract: $75,000 (savings + brokerage)

Net coverage needed: $2,635,000 − $75,000 = $2,560,000

Existing employer group life policy: $180,000 (2× salary)

Coverage gap: $2,560,000 − $180,000 = $2,380,000

A healthy 38-year-old purchasing $2,500,000 of 25-year term life insurance might pay approximately $180–$250/month — leaving the family fully protected.

• Income replacement is the dominant component: For most working-age parents, the I in DIME accounts for 60–75% of the total need. This is why "10× salary" approximates DIME only for people without significant mortgage or education obligations.
• Adjust income years for each stage of life: Revisit the income replacement years as your youngest child ages. A 35-year-old with an infant needs 22–25 years of replacement; the same person at 50 with a 16-year-old needs only 6–9 years. Recalculate every 5 years or after major life events.
• Final expenses add a fixed buffer: Even if all four main components are covered, deaths generate immediate cash needs — funeral costs ($8,000–$15,000), estate legal fees, and estate administration. Including $15,000–$25,000 in final expenses prevents a liquidity crunch at an already difficult time.
• DIME assumes income replacement on a dollar-for-dollar basis: The method does not account for investment returns on the death benefit. A more sophisticated approach (Human Life Value method) discounts the income stream at an assumed investment return — this produces a lower coverage number, but DIME's simplicity and conservatism make it the standard planning tool.
• Run DIME for both spouses: Even a non-working spouse contributes significant economic value through childcare and household management ($40,000–$80,000/year in replacement services). A non-working spouse's death doesn't eliminate the income need — it creates a new childcare and household expense. The DIME method should be applied to both partners, using the replacement cost of services for the non-earning spouse's "income" component.
