The Quick Rule: 10–12x Your Income
The most common rule of thumb is to carry 10 to 12 times your annual income in life insurance coverage. If you earn $75,000/year, that means $750,000 to $900,000 in coverage.
This rule works well as a starting point, but it doesn't account for your specific debts, dependents, or assets. For a more precise number, use the DIME method below.
The DIME Method (More Accurate)
DIME stands for Debt, Income, Mortgage, and Education. Add these four numbers together for a personalized coverage estimate:
Debt — All debts except your mortgage
Credit cards, car loans, student loans, personal loans, medical debt. Your life insurance should cover these so your family isn't left with them.
Income — Your annual income × years until retirement
If you earn $80,000/year and have 25 years until retirement, that's $2,000,000 in income replacement. Many people use 10 years as a simplified figure.
Mortgage — Your remaining mortgage balance
The full payoff amount so your family can keep the home without the monthly payment burden.
Education — Future education costs for your children
Estimate $100,000–$200,000 per child for a 4-year college education in 2026 dollars, depending on your goals.
Example DIME calculation: Debt $25,000 + Income ($80K × 10 years = $800,000) + Mortgage $280,000 + Education (2 kids × $150K = $300,000) = $1,405,000 in recommended coverage.
Coverage by Life Situation
| Situation | Recommended Coverage |
|---|---|
| Single, no dependents, no debt | $100,000 – $250,000 (final expenses only) |
| Married, no kids, dual income | $250,000 – $500,000 (mortgage + debt) |
| Married, 1–2 kids, single income | $750,000 – $1,500,000 |
| Married, 3+ kids, single income | $1,000,000 – $2,000,000 |
| Married, kids, dual high income | $500,000 – $1,000,000 each |
| Retired, no dependents | $50,000 – $250,000 (final expenses/estate) |
What to Subtract From Your Coverage Need
Your coverage need is reduced by assets your family would already have:
- Existing savings and investments
- Existing life insurance through your employer
- Spouse's income and savings
- Social Security survivor benefits (for families with minor children)
If your DIME calculation comes to $1,200,000 but you have $300,000 in savings and $200,000 in employer coverage, your additional needed coverage is $700,000.
How Long Should Your Term Be?
Choose a term length that covers your longest financial obligation:
- 20-year term — most popular, covers young children through college and most of a mortgage
- 30-year term — ideal if you have young children and a new 30-year mortgage
- 10-year term — good for a specific debt or if you're closer to retirement

The Human Life Value Method
A second approach to calculating coverage is the Human Life Value (HLV) method, which takes an economic perspective on what your life is worth to your family. Instead of looking at debts and expenses, it estimates the total income you would have earned over the rest of your working life.
The formula: (Annual income − personal expenses) × remaining working years
For example: A 35-year-old earning $90,000/year who spends $20,000 on themselves has a net income contribution of $70,000/year. With 30 working years remaining, their HLV is $2,100,000. This gives a more generous coverage target than the 10x rule, which would suggest $900,000.
Financial planners often use the DIME method as a floor and the HLV method as a ceiling, choosing a coverage number that falls between them based on budget and risk tolerance.
Is Employer-Provided Life Insurance Enough?
Most employers offer group life insurance — typically one to two times your annual salary as a free benefit, with optional buy-ups available. This sounds convenient, but it has significant limitations:
- Coverage is usually inadequate. One to two times salary falls far short of the recommended 10–12x. On a $70,000 salary, employer coverage provides $70,000–$140,000 — when your family likely needs $700,000–$900,000.
- Coverage ends when you leave the job. If you're laid off, change jobs, or retire, your group life insurance disappears. If your health has declined in the meantime, you may not be able to replace it at a reasonable cost.
- You can't control the terms. Employer group policies are owned by your employer, not you. Terms and coverage amounts can change at any time.
- Buy-ups can be expensive. Optional group life buy-ups are often priced at blended group rates that may not reflect your individual health, meaning young, healthy employees can typically find better rates on the open market.
Rule of thumb: Treat employer life insurance as a supplement, not a solution. Purchase an individual policy for your core coverage need and let employer coverage be a bonus on top.
The Life Insurance Laddering Strategy
Laddering is a technique where you buy multiple term policies that expire at different times, rather than one large policy that runs through your longest obligation. It reduces total premium cost because you're not paying for coverage you no longer need.
Example for a 35-year-old with a $1.2M coverage need:
| Policy | Coverage | Term | Purpose | Monthly Cost |
|---|---|---|---|---|
| Policy 1 | $500,000 | 30 years | Full income replacement, all obligations | ~$55/mo |
| Policy 2 | $400,000 | 20 years | Mortgage + education costs | ~$30/mo |
| Policy 3 | $300,000 | 10 years | Young children while they're dependent | ~$18/mo |
| Total | $1,200,000 | Various | Right coverage at every life stage | ~$103/mo |
After 10 years, Policy 3 expires and the monthly cost drops to $85/mo. After 20 years, Policy 2 expires and the cost drops to $55/mo. Meanwhile, your mortgage is paid off and your children are independent — so you needed less coverage anyway.
Compare this to buying a single $1.2M 30-year term policy at ~$130/month. Laddering saves ~$27/month for the first 10 years, $45/month in years 11–20, while providing the same total coverage when it's most needed.
Life Events That Should Trigger a Coverage Review
Life insurance isn't a set-it-and-forget-it decision. Your coverage need changes as your life does. These events typically require revisiting your policy:
- Marriage — You now have a dependent (spouse) and potentially shared debts. Coverage should increase significantly.
- First child — This is usually the point when people most urgently need substantial life insurance. The coverage need jumps dramatically.
- Additional children — Each child adds years of financial dependency and education costs to your obligation.
- Home purchase — A mortgage is often the largest single financial obligation in your DIME calculation. Your coverage should match or exceed the payoff amount.
- Significant income increase — A raise from $60,000 to $120,000 nearly doubles your income replacement need. Your existing policy may be inadequate.
- Divorce — May reduce coverage need (no longer covering spouse income) but custody arrangements for children may require maintaining or increasing coverage.
- Aging parents who depend on you financially — If you're providing financial support to aging parents, they become financial dependents who factor into your coverage calculation.
- Business ownership — Business owners have additional needs: key person insurance, buy-sell agreement funding, and business debt coverage that go beyond personal coverage.
- Policy expiration approaching — If your term policy expires in 3–5 years, start planning now. Rates will be higher at your current age than when you first bought, and if your health has changed, you'll want time to shop around.
Common Mistakes When Calculating Coverage Needs
Even people who try to calculate their coverage need carefully often make these errors:
Mistake 1: Using Gross Income Instead of Net
The DIME income calculation should reflect what your family actually spends, not your gross income. If you earn $100,000 but take home $72,000 after taxes and retirement contributions, use the $72,000 figure. Alternatively, some people calculate based on what it would cost to replace their lifestyle, not their gross paycheck.
Mistake 2: Forgetting Non-Working Spouse Coverage
If a stay-at-home parent dies, the surviving parent must pay for childcare, household management, meal preparation, and other services. These costs easily add up to $35,000–$60,000 per year. A non-working spouse should be insured for at least $500,000–$750,000 in most families with young children.
Mistake 3: Not Accounting for Inflation
A policy purchased today will pay out a fixed dollar amount in the future. A $1,000,000 death benefit paid in 20 years has less purchasing power than $1,000,000 today due to inflation. When calculating coverage, consider adding a 20–30% inflation buffer, particularly for long-term income replacement calculations.
Mistake 4: Counting Illiquid Assets
Many people subtract their home equity from their coverage need, thinking a surviving spouse can sell the house. But a surviving spouse with children may not want to — or be able to — sell and move. Count home equity only if you realistically expect it to be liquidated.
Mistake 5: Buying Too Little to Save on Premiums
It seems logical to save money by buying less coverage. But an extra $250,000 in term coverage for a 35-year-old costs roughly $12–$15/month. The cost of being underinsured — your family struggling financially — is far greater than $15/month. Erring slightly high is almost always the better financial decision.
