What Is the DIME Method for Life Insurance?
DIME is a widely-taught, simple framework for estimating how much life insurance coverage a household may need. It stands for Debt, Income, Mortgage, and Education — four major financial obligations that a family could struggle to cover without the deceased person's income. Adding these four components together gives a total coverage need, and subtracting any life insurance you already have (plus liquid savings and investments) shows your remaining coverage gap: the additional amount of coverage that might be worth considering.
How to Use the Calculator
- Enter your non-mortgage debt (credit cards, auto loans, personal loans, student loans).
- Enter your annual income and choose how many years of income you'd want replaced for your family.
- Enter your remaining mortgage balance.
- Enter the number of children and an estimated education cost per child (default $100,000, editable).
- Enter any existing life insurance coverage and liquid savings/investments to see your coverage gap.
The DIME Formula
Why Each Component Matters
- Debt: Non-mortgage debts like credit cards, auto loans, and personal loans don't disappear when someone passes away — they can become a burden on surviving family members or the estate. Covering this debt prevents it from eating into other assets.
- Income replacement: This is usually the largest component. It estimates how many years of your income your family would need replaced to maintain their standard of living, cover childcare, or allow a surviving spouse time to adjust financially.
- Mortgage: Paying off the remaining mortgage balance means your family could keep the home without the added stress of a monthly mortgage payment on a reduced income.
- Education: Setting aside funds for children's future education helps protect long-term opportunities that a lost income could otherwise put at risk. The per-child default here is a rough, editable planning estimate for a four-year public college, not a specific tuition forecast.
Worked Example
Debt: $20,000
Income replacement: $80,000 × 10 years = $800,000
Mortgage: $250,000
Education: 2 kids × $100,000 = $200,000
Total DIME need: $1,270,000
Minus $50,000 existing coverage → Coverage gap: $1,220,000
Limitations of the DIME Method
DIME is a helpful starting point, not a precise calculation of your family's exact needs. It doesn't account for things like final expenses (funeral costs), a spouse's own income and ability to work, inflation over long time horizons, other assets like retirement accounts, or non-financial considerations like childcare needs. It's best used as a conversation-starter with a licensed insurance agent or financial advisor, who can tailor the numbers to your full financial picture.

Frequently Asked Questions
DIME stands for Debt, Income, Mortgage, and Education — four common financial obligations a family might otherwise struggle to cover without a primary earner's income. Adding these together gives a simple, widely-used estimate of total life insurance coverage need.
There's no single right answer — it depends on how long your family would need supplemental income, such as until children are grown or a spouse reaches retirement. Common planning horizons range from 5 to 20 years; this calculator lets you choose the number that fits your situation.
It's a rough, editable planning placeholder representing a general estimate for four years at a public college, not a forecast of your specific child's future tuition. Education costs vary enormously by school type, location, and future inflation, so feel free to adjust this figure up or down to match your own goals.
