Tip
The income leg dominates the DIME total. For a $80k earner replacing 15 years, the income leg alone is $1.2M. Be honest about the actual gap, if the surviving spouse can earn enough to cover ongoing expenses, the income leg shrinks dramatically.
Understanding the DIME Method
D, Debt
Add up every non-mortgage debt: credit cards, auto loans, student loans, personal loans, medical debt. The intent is that your death wipes out the balance sheet for your survivors so they start clean.
I, Income
Multiply annual income by the number of years your family needs replacement. Common picks: until the youngest child reaches financial independence, or until the surviving spouse reaches retirement age. For a $80k earner with kids ages 4 and 6, replacing 18 years gets the youngest through college.
M, Mortgage
The current mortgage balance, so the surviving spouse can pay it off and stay in the home without the monthly payment. This is the most defensible leg of DIME, the number is precise and the benefit is obvious.
E, Education
Projected education cost per child, multiplied by the number of children. $100k/child is a reasonable default for a four-year in-state public university; $200k-$300k/child for private. Some planners use a 529-funded target instead.
Frequently Asked Questions
What does DIME stand for in life insurance?
DIME stands for Debt + Income + Mortgage + Education. It is a four-part formula widely used by fee-only financial planners to size a term life policy. You add up all non-mortgage debt, the income replacement need (annual income × years your family needs replacement), the mortgage balance, and the projected education cost for each child.
How many years of income should I replace with the "I" in DIME?
The conservative answer: until the youngest child is financially independent (typically age 22-24). The aggressive answer: until the surviving spouse reaches full retirement age. Most planners use 10-20 years. Shorter if the surviving spouse has a strong career and lower if you have already accumulated significant assets.
Does DIME include final expenses or emergency fund?
The classic DIME formula does not, but a refined version sometimes adds an "F" for final expenses ($15-25k funeral + final medical) and an emergency-fund top-up. Some advisors call this "DIME-F" or "DIMER". The numbers tend to be small relative to the DIME total but worth including for completeness.
How does DIME compare to the 10x income rule?
DIME is bottom-up: build coverage from actual obligations. 10x income is top-down: pick a multiple. For a family with a $350k mortgage, three young kids, and $40k of debt, DIME usually beats 10x because the mortgage + education legs alone exceed 10x for many earners. For a single high-earner with no debt or dependents, 10x usually overstates need.
Does DIME assume the surviving spouse stops working?
No. DIME measures the income GAP your death would create. If the surviving spouse can fully cover household expenses with their own income, the income leg shrinks to zero. If the deceased was the sole earner, the income leg is full annual income times the replacement years. Adjust the income input to reflect the actual gap.
