How Much Life Insurance Do I Need? Calculate It in Four Steps
The right number does not come from a magic rule. It comes from your debts, your income, your mortgage, and your children's education. Here is the step-by-step calculation with a real example.
How Much Life Insurance Do I Need? Calculate It in Four Steps
0:00 / 0:00
"How much life insurance do I need?" is the question we hear most often, and the short answer is: enough for your family to keep their life if your income disappeared tomorrow. The long answer takes four steps and less than twenty minutes with your numbers in hand.
The quick rule: 10 to 15 times your annual income
A common industry benchmark is to buy 10 to 15 times your annual income. If you earn $45,000 a year, that points to $450,000 to $675,000 of coverage. It is a good first approximation, but it ignores your debts, whether you have young children, and whether your spouse also works. That is why the DIME method is worth the extra minutes.
The DIME method, step by step
DIME stands for Debt, Income, Mortgage, Education. Add up those four items and you have the coverage your family actually needs.
1. Debt and final expenses
Credit cards, car loans, personal or business loans, and the cost of a funeral. According to the National Funeral Directors Association's 2023 General Price List Study, the median cost of a funeral with viewing and burial in the United States is $8,300, rising to almost $10,000 when a vault is required. If your family would want to repatriate your body, add several thousand more.
2. Income
Multiply your annual take-home income by the number of years your family would need it. A practical reference: until your youngest child turns 18 or finishes college.
3. Mortgage
The outstanding balance on your home. If you rent, estimate the years of rent you want covered.
4. Education
An estimate per child. You can use the current cost of a public university in your state as a reference and refine it with an advisor.
A worked example
A family in Texas: a 35-year-old father, take-home income of $48,000, two children aged 4 and 7, and a remaining mortgage of $180,000.
| Item | Calculation | Amount |
|---|---|---|
| Debt and final expenses | $12,000 in debt + $10,000 funeral | $22,000 |
| Income | $48,000 × 14 years (until the youngest turns 18) | $672,000 |
| Mortgage | Outstanding balance | $180,000 |
| Education | 2 children × $40,000 | $80,000 |
| DIME total | $954,000 |
From that total you subtract what you already have: liquid savings, life insurance through work, and your spouse's current coverage. If the family already has $100,000 between savings and group insurance, the real need is about $850,000.
What if I cannot afford that much coverage?
This is where the type of policy matters. A 20-year term policy buys far more coverage per dollar than a permanent policy, and many families pair it with a small permanent policy for final expenses. The priority is covering the full need, even if it is with term; the permanent component can be built later.
Frequent mistakes
- Relying only on work coverage. It is usually one or two times salary and disappears when you change jobs.
- Not insuring the parent who cares for the children. If that person is gone, the family would have to pay for childcare and household work.
- Forgetting inflation. Coverage calculated today is worth less in fifteen years; review the policy every time your life changes: a child, a house, a business.
- Hiding health information. A false statement can void the policy exactly when your family needs it.
How often to revisit the number
Review your coverage when a child is born, when you buy a home, change jobs, marry or divorce, or when a large debt is paid off. A fifteen-minute annual review is enough.
Run the numbers with an advisor
If you would rather have someone calculate it with you, request a free consultation. A licensed FFA advisor reviews your numbers, compares quotes, and shows you how much protection fits your budget. If you are also interested in a retirement savings strategy, learn about indexed universal life insurance.
