How Much Life Insurance Do You Actually Need

Last updated July 2, 2026

The rule of thumb of carrying ten times annual income in life insurance is a starting point, not a ceiling. The real calculation is more specific: what income would your dependents need to replace, for how many years, and what assets already exist to cover that gap? A 38-year-old with two children, a mortgage with $280,000 remaining, $45,000 in savings, and a $70,000 salary has a very different coverage need than a 55-year-old with grown children, a paid-off house, and $400,000 in retirement savings. The DIME method, which stands for Debt, Income, Mortgage, and Education, offers a more structured approach: add your outstanding debts, the income your family would need multiplied by years until your youngest is financially independent, your mortgage balance, and estimated education costs. That sum minus existing assets gives you your coverage gap.

Term life insurance is almost always the right product for working-age adults with dependents. A 20-year level term policy covering a 35-year-old in good health runs $25 to $45 per month for $500,000 of coverage. The same death benefit through whole life insurance costs four to ten times more monthly, with the premium difference going toward a cash value component that accumulates slowly and is rarely the most efficient use of the premium dollars. The exception is for estate planning or business succession purposes, where permanent insurance serves specific tax and liquidity functions that term cannot replicate.

The life insurance calculation starts with actual numbers: income replacement years, outstanding debts, mortgage balance, and education costs, then subtracts existing assets. For most families with dependents, that number falls between $500,000 and $1.5 million and is best covered by level term insurance at a fraction of the cost of permanent coverage.
