The DIME Method: Debt, Income, Mortgage, Education

By Amara Taylor · Updated October 13, 2026 · 6 min read

What is the DIME method for life insurance? DIME adds four things your family would have to cover without you: debts (plus final expenses), income for a set number of years, the mortgage balance, and education costs. The total is a rough coverage target. Subtract the life insurance and savings you already have to see the gap.

DIME is one of the most common needs formulas in consumer guides from insurers and personal-finance sites. It is popular because each line maps to a real bill, so you can see exactly what the cover is for.

The four letters

D

Debt and final expenses

Every debt except the mortgage: car loans, student loans, credit cards, personal loans. Add funeral and related costs. Use a quote from a local provider rather than a national average, because prices vary widely.

I

Income

Your yearly income times the number of years your family would need it. This is usually the biggest line. Pick the years from a date, such as when your youngest child turns 18 or finishes college.

M

Mortgage

The amount needed to pay off the mortgage today, not the original loan. Your latest statement shows the payoff balance.

E

Education

What you want set aside for your children’s schooling and college, as a total. Leave it out if it is not a goal.

A worked example

The household below is invented to show the sum. One parent earns $70,000, the children are 6 and 9, and the family wants income covered for 12 years, until the younger child is 18. Final expenses are an assumption for the example only.

LineWhat is countedAmount
D$25,000 car loan and cards + $15,000 final expenses (assumed)$40,000
I$70,000 × 12 years$840,000
MMortgage payoff balance$280,000
E$60,000 for each of two children$120,000
DIME total$1,280,000
Less group cover from work and savings−$150,000
Coverage gap$1,130,000

The income line is two thirds of the total. Cut the years from 12 to 8 and the gap falls by $280,000, the same size as the whole mortgage line. That is why the years deserve more thought than any other input.

Where DIME is weak

  • No growth or inflation. Income is a flat figure times years. A payout invested sensibly would earn something, while prices and tuition would rise. DIME ignores both.
  • It may pay off a mortgage you would rather keep. Some families prefer to keep a low-rate mortgage and cover the payments from income, which lowers the M line.
  • It does not count other support. A partner’s earnings and Social Security survivor benefits can reduce what the policy needs to provide.
  • Gross or take-home. Most versions use pre-tax income. If your family would spend take-home pay, gross income overstates the need a little.

DIME against other methods

A flat multiple of income, often quoted as five to eight times by sources such as NAIC, gave just $200,000 to $410,000 for the same family once existing cover was subtracted, because it ignores the mortgage and the education goal. Human life value, which counts every working year left, gave about $984,000 with the assumptions in our life insurance needs calculator.

When two methods disagree, the gap usually comes from the years of income or the mortgage. Our post on where the income multiple fails shows three households where the rule misses badly.

Run DIME for your own household and see it next to two other methods.
