How Much Life Insurance Do I Need? The 15-Minute Math
Quick Answer
- A common starting point for life insurance coverage is 10 to 12 times annual income, but the DIME method (Debt, Income, Mortgage, Education) produces a number tailored to a specific household.
- Employer-provided life insurance typically covers only 1 to 2 times salary and usually ends when the job ends.
- Coverage needs are highest during the years a household carries a mortgage and raises children, then typically decline.
- The right amount is a strategy question — the policy type comes after the number, not before.
Most people guess at life insurance coverage the same way they guess at how much water a road trip needs. The difference is that getting this number wrong doesn’t leave anyone thirsty — it leaves a family with a mortgage they can’t pay. The math takes about 15 minutes. Here’s the version worth doing.
What is the DIME method?
DIME adds four numbers to produce a coverage target: Debt, Income, Mortgage, and Education. It takes minutes and beats every rule of thumb.
- Debt — total every non-mortgage balance: cards, auto loans, personal loans, private student loans that don’t discharge at death.
- Income — annual income multiplied by the years the household would need support. Ten years is a common choice; families with young kids often choose more.
- Mortgage — the payoff balance, not the monthly payment.
- Education — a realistic per-child figure for future schooling.
Add the four, subtract existing coverage and liquid savings, and the remainder is the gap a policy needs to fill.
Why isn’t work coverage enough?
Employer life insurance usually pays 1 to 2 times salary — a fraction of what the DIME math produces for most households. It also has a quieter problem: the coverage typically ends the day the job does. A layoff, a career change, or a move to self-employment can erase the entire safety net at exactly the wrong moment. Workplace coverage is a nice bonus. It is not a plan.
Once the coverage number is set, the next decision is the policy type — and the term vs. whole life choice changes the monthly cost by 5x to 15x for the same death benefit.

Life insurance needs follow a curve, not a straight line. Needs peak during the mortgage-and-young-children years, when a lost income would hit hardest and the longest list of obligations remains. As the mortgage shrinks, children finish school, and retirement savings grow, the amount of coverage a household actually needs typically declines. This is why the strategy conversation matters more than the product pitch: the right structure anticipates the curve instead of selling one large number forever.
What about non-working partners?
A stay-at-home parent produces enormous economic value that a survivor would have to replace with paid services: childcare, transportation, household management, and more. Estimates of that replacement cost routinely exceed $100,000 per year. Coverage on both partners, sized to each partner’s economic contribution, is the standard-of-care answer.
The number comes first. The product comes second. That order is the whole point.
Frequently Asked Questions
Is 10 times income enough life insurance?
Ten times income is a rough starting point, not an answer. A household with a large mortgage and young children often needs more, while a household with grown children and low debt may need less. The DIME method produces a more accurate figure.
What is the DIME method for life insurance?
DIME stands for Debt, Income, Mortgage, and Education. Add all non-mortgage debt, income replacement for a chosen number of years, the remaining mortgage balance, and expected education costs. The total is the coverage target.
Does employer life insurance count toward coverage needs?
Employer coverage counts, but typically provides only 1 to 2 times salary and ends when employment ends. Most advisors treat workplace coverage as a supplement, not the foundation.
Do stay-at-home parents need life insurance?
Yes. Replacing the childcare, transportation, and household management a stay-at-home parent provides carries a real annual cost, often estimated well above $100,000 per year. Coverage on both partners is the standard recommendation.
Does life insurance cost more with age?
Yes. Premiums are priced on age and health at the time of application, and rates generally rise every year an application is delayed. Locking coverage earlier is nearly always cheaper over the life of the policy.
