Life Strategies · The D.I.M.E. method

How much life insurance do I need?

Add up Debt, Income, Mortgage and Education, subtract what you already have, and get a ballpark estimate in about a minute.

If someone depends on your income, a simple estimate is a useful place to start. D.I.M.E. is a widely used rule of thumb that turns four big questions into one number: what would need to be paid off, how much income would need replacing, what is left on the home, and what education costs lie ahead. Your result is an educational estimate based only on the numbers you enter.

Understanding the math

The D.I.M.E. method estimates how much money your family might need if your income stopped because you passed away. It does not try to predict the future. It simply adds up four groups of costs that would not go away, then subtracts the resources you already have in place. The result is a rough, educational estimate that can help you start a conversation about income protection.

The formula, step by step

First, the calculator adds your debts to pay off and your final expenses to get Debt. Next, it multiplies your annual income by the number of years you want to replace it to get Income. It then takes your remaining mortgage balance as Mortgage, and multiplies the number of children by the cost per child to get Education. These four amounts are added together to make your D.I.M.E. total need. Finally, it subtracts your personal life insurance, your coverage through work and the savings you would use. If the answer is above zero, that is the estimated additional coverage; if what you have is larger than the total, the result shows $0.

Worked example (the default numbers)

Debt: $20,000 of debts + $15,000 of final expenses$35,000
Income: $75,000 a year × 10 years$750,000
Mortgage: remaining balance$280,000
Education: 2 children × $100,000$200,000
D.I.M.E. total need$1,265,000
Minus personal life insurance ($0), work coverage ($150,000) and savings ($15,000)−$165,000
Estimated additional coverage$1,100,000

In this example, income replacement is the largest piece, at $750,000 of the $1,265,000 total, which is about 16.9 times the $75,000 income. If the $150,000 of work coverage ended, the estimate would rise to $1,250,000.

What the result does not include

The calculator works only with the amounts you type in. It does not adjust for inflation, assume any investment growth, or account for taxes, fees, Social Security survivor benefits, a spouse's income or changes in your family's spending. It also does not check whether income replacement and the mortgage overlap. Treat the result as a starting point: try different years of income or education costs to see how sensitive it is, and revisit it after big life events such as a new child, a home purchase or a job change.

Frequently asked questions

What is the D.I.M.E. method?

D.I.M.E. stands for Debt, Income, Mortgage and Education. It is a simple rule of thumb for estimating how much money a family might need if a breadwinner passed away: pay off debts and final expenses, replace income for a number of years, pay off the mortgage, and fund children's education. This calculator then subtracts life insurance and savings you already have. It is a starting point for a conversation, not a complete needs analysis.

How many years of income should I enter?

There is no single right answer. Many people use the number of years until their youngest child is grown, or until a spouse could reasonably adjust, retire or rely on other income. The default example uses 10 years. Try a few values to see how much the estimate changes; income replacement is often the largest part of the total. The calculator accepts 0 to 60 years, including halves such as 7.5.

Should I count life insurance through work?

You can, and the calculator subtracts it, but it is shown separately for a reason. Group coverage through an employer often ends or changes if you leave, retire or change jobs, and it may not be portable. The results also show what the estimate would be without work coverage. In the default example that is $1,250,000 instead of $1,100,000.

Am I counting the mortgage twice?

Possibly. D.I.M.E. pays off the mortgage balance as its own item, so your family would no longer have mortgage payments. If your income figure is meant to cover those payments as well, the same cost is counted twice. Some people lower the income amount or the number of years to account for this. Either way, the result is an estimate based only on the numbers you enter.

Does this include inflation, investment returns or Social Security?

No. The calculator adds and subtracts the dollar amounts you enter. It does not adjust for inflation, assume any investment growth on savings or a payout, or include taxes, fees, Social Security survivor benefits or a spouse's income. Those factors can make an actual need higher or lower, which is one reason to review your estimate with a licensed professional.

Is anything I enter saved or shared?

No. The calculation runs in your browser. Your numbers are not saved, and they are not sent to NeoPenn or to analytics. If you use the share buttons, the message includes only the link and a general sentence, unless you tick the box to include your estimate. Website analytics, if you accept cookies, record that the calculator was used, without any of your numbers.

Is this a recommendation to buy life insurance?

No. This tool is for general education and information only. It is not financial, insurance, tax or legal advice, and it is not an offer or recommendation to buy any product. Life insurance is subject to underwriting, eligibility and policy terms. If you would like to talk through your situation, you can request an optional appointment with a licensed professional.

How is this calculated?
D Debt = debts to pay off + final expenses I Income = annual income × years to replace M Mortgage = remaining mortgage balance E Education = number of children × cost per child D.I.M.E. total need = D + I + M + E Estimated additional coverage = D.I.M.E. total need − personal life insurance − coverage through work − savings (shown as $0 if the result is below zero) Without work coverage = D.I.M.E. total need − personal life insurance − savings Income multiple = D.I.M.E. total need ÷ annual income

Allowed inputs (anything outside is adjusted, with a note under the field):

  • Debts $0 to $10,000,000 · final expenses $0 to $1,000,000
