Life Insurance Calculator
Estimate how much life insurance coverage you need using the DIME method — Debt, Income replacement, Mortgage, and Education — minus what you already have.
How the DIME method works
Additional coverage needed = Total need − Existing coverage − Savings
DIME breaks down life insurance need into four concrete categories rather than a single vague income multiple: Debt your family would inherit, Income your dependents would need replaced for a chosen number of years, remaining Mortgage balance, and future Education costs for children. Adding these up — then subtracting what you already have — gives a more tailored number than a generic "10x your salary" rule.
Debt $15,000 + Income replacement ($70,000 × 10 years = $700,000) + Mortgage $220,000 + Education $60,000 = $995,000 total need.
Minus $100,000 existing coverage and $20,000 savings: $875,000 in additional coverage needed.
Debt $5,000 + Income replacement ($45,000 × 15 years = $675,000, a longer horizon since the children are young) + Mortgage $0 (renting) + Education $80,000 (two children) = $760,000 total need.
Minus $0 existing coverage and $2,000 savings: $758,000 in coverage needed — nearly as large as the homeowner example above despite a lower income, because more years of income replacement and no existing coverage offset the smaller salary and absent mortgage.
How each DIME category is typically estimated
| Category | How it's usually estimated |
|---|---|
| Debt | Sum of non-mortgage balances: credit cards, auto loans, personal loans |
| Income replacement | Annual income × years of support needed (commonly 10–20 years) |
| Mortgage | Remaining mortgage balance (zero if renting or the home is paid off) |
| Education | Estimated total college cost per child still to come |
Why a flat income multiple often misses the mark
A common shortcut is "buy 10x your income," but that number ignores your specific mortgage balance, existing debt, and how many years of income replacement your family would actually need — a family with a large remaining mortgage and young children needing college funding has very different needs than someone with a paid-off house and grown children, even at the same income level. DIME accounts for those differences explicitly.
Common mistakes when estimating life insurance needs
- Forgetting to subtract existing coverage. Employer-provided group life insurance counts and should reduce how much additional coverage you need to buy.
- Choosing an arbitrary number of income-replacement years. Consider how long dependents would realistically need support — until children are grown, a spouse retires, or a specific milestone.
- Ignoring future education costs entirely. They're often one of the largest and most overlooked categories in a coverage estimate.
Frequently asked questions
What is the DIME method for life insurance?
Debt, Income replacement, Mortgage, and Education — four categories added together to estimate total coverage need.
Is 10 times my income enough life insurance?
It's a rough rule of thumb; DIME's category-by-category approach tends to be more accurate for most households.
Should I subtract my existing savings and coverage?
Yes — existing coverage and liquid savings reduce the additional amount you need to buy.
Do I need life insurance if I don't have dependents?
Generally less urgent, though some people still carry a small policy for final expenses.
How many years of income replacement should I choose?
Commonly 10-20 years — often until the youngest child is independent or a spouse reaches retirement age.
Does term or whole life insurance matter for this calculation?
No — DIME estimates the coverage amount needed regardless of policy type. Term life is usually the cheaper way to meet that need.
