When most people calculate their life insurance need, they multiply their income by 10 and call it a day. The DIME method is slower — but far more accurate. It breaks your financial obligation into four distinct categories, ensuring nothing gets overlooked.

What DIME Stands For

D

Debt — Everything Except the Mortgage

Add up all your non-mortgage debts: credit card balances, auto loans, student loans, personal loans, and any medical debt. Also include final expenses and estimated funeral costs (typically $12,000–$20,000). If you die, these debts don't disappear — your estate or surviving spouse becomes responsible for them.

I

Income — Present Value of Future Earnings

The income component replaces your salary for the years your family depends on it. Rather than simple multiplication, DIME uses present value: the lump sum needed today, invested at a modest return, to generate your annual income for a specific number of years.

Formula: PV = Annual Income × [(1 − (1+r)⁻ⁿ) / r]

Where r = assumed annual investment return and n = number of years of coverage needed. At 5% return and 20 years of coverage, $75,000/year requires a present value of approximately $935,000.

M

Mortgage — Full Remaining Balance

Include the full remaining mortgage balance so your family owns the home free and clear. Many families underestimate coverage because they forget to explicitly account for this. If you have a $300,000 mortgage, that is $300,000 your family needs to not worry about during what will already be an incredibly difficult period.

E

Education — Per-Child Cost Estimate

Estimate the education fund needed for each child. A conservative estimate for four years of college (tuition, room and board, fees) at a state university is $80,000–$120,000. Private university costs are considerably higher. Multiply by the number of children you want to cover.

DIME vs. 10× Rule: A Real Example

Consider a 38-year-old earning $90,000/year with a spouse and two young children:

10× Rule: $90,000 × 10 = $900,000

DIME Method:

D (Debt + funeral): $42,000 credit cards + auto + student + $15,000 funeral = $57,000
I (Income PV): $90,000 × 20yr at 5% = $1,120,000
M (Mortgage): $320,000
E (Education × 2): $200,000
DIME Total: $1,697,000

The 10× rule produced $900,000 — DIME produced $1,697,000. The difference is significant. After subtracting $250,000 in existing coverage and $80,000 in savings, the gap is $1,367,000 in additional needed coverage.

Subtracting Existing Resources

After calculating the DIME total, subtract what you already have: existing life insurance policies, liquid savings and investments, and employer group coverage (note: employer coverage is typically not portable, so consider whether to include it).

The remaining amount is your coverage gap — what you should purchase in additional term life coverage.

DIME as an Upper Bound

The DIME total represents a comprehensive "fully covered" figure. Most financial planners suggest using it as an upper bound and income replacement as a lower bound — then choosing a policy amount that fits your budget within that range. Partial coverage is better than none.

Frequently Asked Questions

What does DIME stand for in life insurance?
Debt, Income, Mortgage, and Education. Each letter represents a major financial obligation that should be covered by life insurance if the primary earner dies.
How is the DIME method different from the 10× rule?
The 10× rule multiplies annual income by 10 — fast but imprecise. DIME is more thorough: it explicitly accounts for total outstanding debt, present value of income, full mortgage payoff, and education funding for each child. DIME typically produces a higher, more accurate number.
What debts are included in the DIME method?
All debts except the mortgage: credit cards, auto loans, student loans, personal loans, medical debt, and estimated funeral/final expenses. The mortgage is tracked separately under M.
How do I calculate the Income component of DIME?
PV = Annual Income × [(1 − (1+r)^(−n)) / r], where r is an assumed investment return and n is the number of years. At 5% return over 20 years, $75,000/year requires approximately $935,000 in present value.
Should I subtract my savings from my DIME total?
Yes. After calculating the DIME total, subtract existing life insurance, liquid savings, and other liquidable assets. The difference is your actual coverage gap — the additional amount you should purchase.
