Life Insurance Needs Calculator

Life insurance coverage need is calculated to ensure your dependents maintain their standard of living if you die unexpectedly. Several methods exist, each making different assumptions about investment returns, inflation, and what costs truly need replacing.

DIME Method (most comprehensive): Coverage = Debt + Income + Mortgage + Education

Where:

• Debt = all non-mortgage debts: car loans, student loans, credit cards
• Income = annual income × years until youngest child is financially independent (or until retirement age for a spouse)
• Mortgage = remaining mortgage balance (to pay off the home)
• Education = projected college costs for each child

Income Replacement Method: Coverage = Annual Income × 10 to 15

Human Life Value Method: Coverage = Present Value of future earnings = Annual Income × (1 − Tax Rate) × [1 − (1+r)^(−n)] ÷ r

Where r = discount rate (3–5%) and n = years to retirement.

What each variable means:

• Income multiplier (10–15×): Reflects that if proceeds are invested at 5–7%, they generate replacement income indefinitely; lower multiplier for shorter income needs, higher for young families
• DIME vs. simple multiplier: DIME is more precise but requires current debt and mortgage information; the multiplier is a quick estimate
• Term life vs. whole life: Term life (20–30 year term) is almost always the right choice for pure income protection; whole life costs 5 to 15 times more for the same death benefit

Reference: average coverage by life stage:

• Young adult, no dependents: $250,000–$500,000 (covers debts + burial)
• Married, no children: 5–7× income
• Young family with children: 10–15× income + mortgage + education
• Pre-retirement, children grown: 3–5× income to protect spouse

Worked example: 34-year-old, $85,000/year income. Spouse stays home. Two children (ages 3 and 6). Mortgage balance: $280,000. Car loan: $18,000. Credit cards: $7,000. College fund wanted: $100,000 per child. Years of income to replace: 18 (until the youngest finishes college).

This calculator takes one combined debt figure rather than splitting the M out of DIME, so the mortgage and the consumer debt go into the same box:

• Debts including mortgage = $280,000 + $18,000 + $7,000 = $305,000
• Income = $85,000 × 18 = $1,530,000
• Education = 2 × $100,000 = $200,000
• DIME Total = $2,035,000, rounded up to $2,050,000

Which of these three calculators to use. This is the fast version: five fields, with the mortgage folded into one combined debt figure. If you want the mortgage broken out, and want your existing savings and any policy through work subtracted to give the gap you still need to buy, use the full coverage needs calculator. Once you have a target number, the premium estimator turns it into a monthly cost.

A note on the education figure. There is no default here on purpose. A four-year in-state public degree and a private one differ by roughly a factor of three, and both move every year, so any number this page pre-filled would be wrong for most families reading it. Look up the current sticker price for the kind of school you have in mind and use that.
