What is the DIME method?
DIME is a simple way to estimate life insurance needs by adding four things a family would have to cover: Debts (plus final expenses), Income for a number of years, the Mortgage balance and Education for children. You then subtract coverage and savings already in place. The result is a rough coverage gap.
Keep the components separate so the family can see what drives the estimate. Debts and final expenses are immediate needs. Income replacement covers a chosen number of years at the share entered. Mortgage is the balance you chose to include. Education is the number of children multiplied by the estimated cost per child. Offsets are existing coverage and savings only when the checkbox is on.
The formula is: debts + final expenses + annual income × years × income share + mortgage + children × education cost, minus selected coverage and savings. The gap cannot be below zero. The displayed discussion amount is rounded to the nearest $1,000. Rounding does not make it a recommendation or a carrier-approved face amount.
Use the result to ask a better question: which obligations matter most, for how long and at a budget the family can maintain? The calculation is transparent so you can change an assumption and explain the difference, rather than treating the final number as authority.
- D
Debts to pay off, excluding the mortgage, plus the family’s estimate for final expenses.
- I
Annual income × years needed × the share of income to replace.
- M
The mortgage balance included in the discussion.
- E
Children needing education funds × estimated cost per child.
- Offsets
Subtract existing coverage and available savings when selected. A negative result is shown as a zero estimated gap.
How do you use this calculator with a client?
Run it together during the fact finder, on screen or on the phone. Ask each question in plain words, enter the client's own numbers, and talk through the result. Then compare the estimate with what they can comfortably afford each month, since a policy they keep is better than a bigger one they drop.
Explain each input before entering it. Ask the client what they want the surviving household to be able to do, then use their numbers. Do not increase an education estimate or income period merely to create a larger coverage result. If someone does not know an amount, mark it as an open question and return to it.
Check whether income replacement and mortgage payoff reflect the same intended expense twice. The simple calculator adds what you enter; it cannot decide whether an assumption is appropriate. Discuss work coverage both with and without it if its continuation is uncertain. Include only savings the family would genuinely make available for these obligations.
After the estimate, return to affordability and priorities. A sustainable policy that addresses a clearly understood need may be more useful than a larger amount the family cannot maintain. This tool does not choose a policy, premium, duration or underwriting class. Keep the recommendation and application process with the appropriately licensed professional and the client.
What does the DIME method leave out?
It ignores inflation, investment growth, taxes, Social Security survivor benefits, a spouse's income, childcare costs, and goals like leaving an inheritance or funding a business buyout. It also assumes the family pays everything off at once. Treat it as a starting point and adjust with the client's real situation.
There is no adjustment here for how prices or purchasing power might change, how savings might grow, taxes or the timing of individual expenses. The calculator does not project the surviving spouse’s earnings or childcare needs. It also does not decide whether a family’s emergency reserve should remain untouched.
Social Security survivor benefits may be relevant for eligible family members, but the calculator neither estimates eligibility nor subtracts a benefit. Use the Social Security Administration’s own information for that discussion. Likewise, use the family’s actual education and final-expense assumptions rather than treating a national average as their budget.
A detailed planning conversation can consider those omissions, changing needs over time and the tradeoff between paying a debt at once or funding ongoing payments. Name the assumptions in the summary. When something falls outside your qualifications, involve an appropriate professional instead of adding a confident-looking number to the tool.
What other ways are there to estimate life insurance needs?
Agents also use an income multiple (a set number of years of income), a detailed needs analysis that projects expenses year by year, and the human life value approach, which estimates the present value of future earnings. DIME sits in the middle: quick enough for a first meeting, detailed enough to start a real conversation.
An income-multiple shortcut can be a quick opening question, but it may miss debt, household resources and the number of years support is needed. A detailed needs analysis can model expenses over time, while introducing more assumptions about timing, inflation and other resources. More complicated math is not automatically a more suitable recommendation.
Choose a method you can explain and check. Ask which facts come from the client, which come from documents and which are estimates. Use the same definitions when comparing methods. If one calculation includes mortgage payoff and another assumes ongoing mortgage payments, the different results may reflect different assumptions rather than an error.
DIME is useful when you need an understandable starting framework. It should leave the family with a clearer view of the obligations they want to protect. It should not replace a full fact finder, product analysis or affordability discussion.
How much life insurance does a family need?
There's no single right number. It depends on who relies on the income, the debts and mortgage, the children's ages and plans, existing coverage and savings, and what the family can afford. The calculator gives a starting estimate; the agent and the client decide together, and the carrier decides what it will approve.
The family’s needs can change after a birth, marriage, separation, new mortgage, job change or death in the household. Existing coverage can also change through a new employer or a policy conversion deadline. Review the estimate when meaningful circumstances change rather than treating a saved worksheet as permanent.
A zero estimated gap means selected resources meet this particular arithmetic estimate. It does not prove no insurance discussion is needed; the method leaves out other goals and timing considerations. A large gap does not prove the family should buy that amount immediately. Keep the full picture, budget and carrier requirements in the conversation.

Worked example: example numbers, not typical figures
- Debts and final expenses
$12,000 debts + $10,000 final expenses = $22,000.
- Income replacement
$60,000 × 10 years × 100% = $600,000.
- Mortgage payoff
$220,000.
- Education
2 children × $50,000 = $100,000.
- Estimated total need
$22,000 + $600,000 + $220,000 + $100,000 = $942,000.
- Already in place
$120,000 existing coverage + $30,000 savings = $150,000.
- Estimated coverage gap
$942,000 − $150,000 = $792,000. This is an illustration for discussion, not a coverage recommendation.

About this estimate
This calculator gives a rough estimate using the DIME method. It's a starting point for a conversation, not a recommendation or a quote. It doesn't account for inflation, investment returns, taxes, Social Security survivor benefits or a family's other resources and goals. The right amount depends on the full picture, the budget and what a carrier will approve.
