No one likes shopping for life insurance, yet almost every financial planner agrees that it is the single most efficient way to protect the people who depend on your paycheck. The hard part is not buying a policy — it is deciding how much coverage you actually need. Too little and your family is exposed; too much and you overpay for decades of coverage you will never use.
This calculator uses the DIME method — Debt, Income, Mortgage, Education — the same rule of thumb published by Bankrate, Policygenius and Investopedia. You enter what you owe, how many years your family needs your income replaced, what you still owe on the home, what you have earmarked for college and final expenses, then subtract the savings and investments you already hold. The result is a dollar figure you can take directly to an agent or an online quote engine.
How to Use
- Enter your Annual Income — your gross household salary before taxes. This is the number your family would lose overnight, so use the combined income if more than one earner contributes.
- Set the Income Replacement Years. The classic DIME rule uses 10, but if you have young children or a non-working spouse, 15 to 20 is more realistic; if your kids are grown and your spouse earns the same, 5 is plenty.
- Fill in Remaining Debts (non-mortgage) — car loans, student loans, credit cards, personal loans. These should disappear the day you do.
- Type your Remaining Mortgage Balance — the outstanding principal on your home. If you want your family to stay in the house, this line pays it off outright.
- Add Future Education Costs for each child you expect to put through college. A typical public four-year run today is $100,000–$200,000 per child.
- Set Final Expenses — funeral, burial, legal and estate-settlement costs. A common default is $15,000.
- Subtract Current Savings & Investments — cash, 401(k), IRA, brokerage accounts and any existing group life insurance. Every dollar you already have reduces the policy you need to buy.
The result card breaks the need into the four DIME buckets, shows the savings offset, and highlights the recommended death benefit as a multiple of your income. As a sanity check, a healthy number lands between 8x and 15x annual income.
The DIME Formula Explained
DIME is a four-part sum, followed by one subtraction:
Recommended Coverage = Debts + (Income × Replacement Years) + Mortgage + Education & Final Expenses − Savings
- D — Debts. Every non-mortgage balance you want cleared. Credit cards at 20% interest can ruin a surviving spouse's cash flow within months.
- I — Income replacement. Your annual salary multiplied by the number of years your family would need it. Ten years is the conservative default; longer if you have toddlers, shorter if your children are near adulthood.
- M — Mortgage. The remaining home-loan principal. Paying it off removes the largest monthly expense from your family's budget.
- E — Education & final expenses. College savings plus funeral and estate costs.
Finally, subtract the savings, 401(k) and existing group coverage you already have. If the result is negative, you are already self-insured and may not need an individual policy at all.
Examples
Example 1 — The canonical DIME household. A 38-year-old teacher earns $80,000, wants 10 years of income replacement, owes $200,000 on cars and student loans, has $300,000 left on the mortgage, has set aside $100,000 for the kids' college, expects $15,000 in final expenses, and holds $200,000 in savings and a 401(k). The math: $200,000 debts + $800,000 income + $300,000 mortgage + $115,000 education and final costs = $1,415,000 total need; subtract $200,000 savings = $1,215,000 recommended coverage, roughly 15x income. A 20-year level term policy in that face amount costs most healthy non-smokers under $60 per month.
Example 2 — A young renter with one child. A 30-year-old software engineer earns $120,000, wants 15 years of replacement, owes $15,000 on a car, has no mortgage, has not yet saved for college, expects $15,000 final expenses, and has $40,000 in savings. The total need is $15,000 + $1,800,000 + $0 + $15,000 = $1,830,000; minus $40,000 = $1,790,000. Round up to $1.8M or $2M — the underwriting pricing difference between those two is tiny, and a higher death benefit leaves margin for inflation over the 20-year term.
Example 3 — The near-retirement empty nester. A 55-year-old earns $95,000, wants only 5 years of replacement, has paid off the car and credit cards, owes $80,000 on the mortgage, no college costs left, $12,000 final expenses, and has $600,000 in a 401(k). Total need: $0 + $475,000 + $80,000 + $12,000 = $567,000; minus $600,000 savings = $0. The calculator correctly returns zero recommended coverage — this household is already self-insured.
Example 4 — The high-income breadwinner. A 45-year-old surgeon earns $350,000, wants 12 years of replacement, owes $50,000 in business debt, has a $1,200,000 mortgage, has reserved $200,000 for two children's college, $20,000 final expenses, and has $300,000 in investments. Total DIME need: $50,000 + $4,200,000 + $1,200,000 + $220,000 = $5,670,000; minus $300,000 = $5,370,000. Because single policies cap around $3M–$5M, this buyer should layer two or three term policies, or pair a small permanent policy with a large 20-year term.
FAQ
How much life insurance do I really need?
Most financial planners recommend between 8x and 15x your gross annual income. The DIME method refines that rule by adding your specific debts, mortgage, education costs and final expenses, then subtracting what you already have saved. For a typical household with young children, the result lands between $1M and $2M of death benefit.
What is the DIME method?
DIME stands for Debt, Income, Mortgage, Education. You add your outstanding non-mortgage debts, your annual salary multiplied by the number of years your family depends on it, your remaining mortgage balance, and future education plus final expenses, then subtract savings and investments. It is the most widely published quick-calculation for life insurance coverage.
Is 10 years of income replacement enough?
Ten years is the classic default, but it depends on your family. If you have a toddler, 15 to 20 years keeps the replacement running through college. If your children are teenagers and your spouse earns a comparable salary, 5 years may be more than enough. The slider on this page lets you test the range instantly.
Should I include my mortgage in life insurance?
Yes — if your goal is to keep your family in the home. Adding the remaining mortgage balance to your DIME calculation means the policy pays off the house outright, removing the largest monthly bill. If you would rather your family sell and downsize, you can leave the mortgage line at zero and rely on the income-replacement portion.
Does my 401(k) or savings reduce the coverage I need?
Yes. Every dollar in cash, 401(k), IRA, brokerage account, or existing group life insurance at work offsets one dollar of coverage you have to buy. Many people with 10+ years of retirement savings are already partially self-insured, which is why subtracting that line matters as much as adding the four DIME buckets.
What is the difference between term and whole life insurance?
Term life covers you for a fixed period — usually 10, 20 or 30 years — and costs very little for a large death benefit. Whole life (permanent) builds cash value and costs 10 to 15 times more per dollar of coverage. For most families with dependents, a 20- or 30-year level term policy sized to the DIME result is the most cost-efficient choice; permanent insurance is usually reserved for estate-tax or business-succession planning.
Is group life insurance through work enough?
Usually not. Most employer plans cover 1x to 2x your salary, and the policy disappears when you change jobs. If your DIME calculation recommends $1.2M of coverage and your group plan provides only $100,000, you still need an individual term policy for the remaining $1.1M.
