Life Insurance Coverage Needs Calculator
Calculate life insurance coverage needed from income replacement, outstanding debts, number of dependents, and future expenses including education and housing.
Why life insurance exists
Life insurance isn’t for you — it’s for the people who depend on your income. If no one would suffer financially when you die, you may not need it. If a spouse, child, business partner, or aging parent counts on your income, you do. The number is what would let them maintain their financial life without you.
The DIME method
DIME — Debt, Income, Mortgage, Education — is the financial-planning shorthand for calculating coverage:
- Debt: Credit cards, auto loans, personal loans, co-signed loans. Money your family inherits the responsibility for.
- Income: Annual income × years of replacement needed. Typically 10-20 years for a young family with kids; less if children are nearly grown.
- Mortgage: Full outstanding balance so survivors can keep the home without a forced sale.
- Education: Future college costs for all children.
Coverage gap = total DIME need − existing savings − existing life insurance.
A worked example
Family with $80,000 annual income, $250,000 mortgage, $20,000 other debts, two children needing ~$100,000 of education funding, $50,000 in savings, and a $100,000 group policy through work:
- Income replacement: $80,000 × 10 = $800,000
- Mortgage: $250,000
- Debts: $20,000
- Education: $100,000
- Total need: $1,170,000
- Less existing assets: $150,000
- Coverage gap: $1,020,000
This is the additional term life insurance to buy.
Income replacement years — the contentious variable
Most planners use 10 years as a default. The honest answer depends on:
- Spouse’s earning ability: A working spouse needing 5-7 years to retrain; a stay-at-home spouse may need 15-20 years
- Children’s ages: A toddler is dependent for 18+ years; a teenager for 4-8
- Lifestyle commitments: Mortgage paid off vs 25 years left
- Existing financial cushion: A near-millionaire couple needs less replacement than a paycheck-to-paycheck one
A conservative approach: cover years until the youngest child finishes college plus 2-3 years’ transition.
The 10x income rule of thumb (and why it can be wrong)
Many calculators just multiply annual income × 10. It’s roughly the right ballpark for typical families, but it can be wildly off in either direction:
- A 35-year-old earning $60k with 3 young kids and a $300k mortgage probably needs 15-20x income
- A 50-year-old earning $200k with no kids, a paid-off house, and $1.5M in retirement might need 0-3x income
- A married couple with no children where both work probably needs 3-5x each for the survivor
DIME is far more accurate than 10x. Use 10x only as a sanity check.
Term vs whole life — the major decision
| Type | Premium | Best for |
|---|---|---|
| Term (20-30 year) | $200-$600/yr for healthy 35yo, $1M coverage | 95% of buyers |
| Whole life | $7,000-$15,000/yr for same coverage | Very specific estate planning needs |
| Universal life (UL) | Variable, complex | Sophisticated high-net-worth planning |
| Final expense | Low coverage ($10k-$25k), $30-$80/mo | Elderly without other assets |
Term life is the answer for almost everyone. It’s cheap because it’s pure insurance with no investment component. The “death probability per year” is genuinely low for a healthy 35-year-old, so the math works out to $200-$500/year for $1M of 20-year term.
Whole life is sold heavily because the agent commission is enormous (first-year premium is mostly commission), not because it’s better for buyers. The “cash value” growth is typically 1-3% over 20-30 years — far below what the same money invested in index funds would do. The honest financial planning advice: buy term, invest the difference.
Typical term life premiums (2024, healthy non-smoker)
| Age | $500k 20-year term | $1M 20-year term | $1M 30-year term |
|---|---|---|---|
| 25 | $190 | $300 | $400 |
| 30 | $200 | $320 | $440 |
| 35 | $230 | $370 | $530 |
| 40 | $310 | $510 | $750 |
| 45 | $470 | $790 | $1,200 |
| 50 | $720 | $1,200 | $1,900 |
| 55 | $1,150 | $1,950 | $3,150 |
| 60 | $1,900 | $3,300 | $5,400 |
Smokers pay 2-3x these rates. Pre-existing conditions raise rates 1.5-3x. The cheapest option for almost anyone is buying as young as possible and locking in the rate for the full term.
Group life insurance through work is usually not enough
Most employers offer 1-2x salary in group life as a free benefit. That sounds generous but is typically far below DIME need. Treat it as a small supplement, not a replacement for individual coverage.
Important caveat: group life ends when you leave the job. Don’t make it the only coverage you have.
The “ladder strategy”
A common approach for someone with declining future needs: buy multiple smaller term policies that expire at different times instead of one large 30-year policy.
Example: $1M total need, dropping over time
- $500k 10-year term ($300/yr)
- $300k 20-year term ($200/yr)
- $200k 30-year term ($150/yr)
- Total: $650/yr for $1M coverage now, decreasing to $200k in years 20-30
Compare to flat $1M 30-year: $530/yr for $1M throughout. The ladder is more expensive in early years but cheaper overall if your needs really do decline (kids grow up, mortgage gets paid).
What insurers actually require
For most policies under $1M, a paramed exam (basic health screening at home) plus medical records lookup. Above $1M, usually a doctor’s exam, blood test, urine test, and sometimes an EKG. The underwriting process takes 4-8 weeks.
Issues that increase rates or cause denial:
- Smoker/recent quit (within 12-24 months)
- BMI over 32 or under 18
- Recent diagnosis of cancer, heart disease, diabetes
- Major depression with hospitalization
- Bankruptcy or felony in recent years
- Risky hobbies (rock climbing, private piloting, scuba)
- DUI or significant driving record
Shopping efficiently
Don’t go directly to one insurer’s website — they only sell their product. Use a broker:
- Term4Sale (term4sale.com) — fee-only quote engine, no agents
- Zander Insurance — independent broker, no upselling
- Quotacy — online quotes from 20+ carriers
- Policygenius — heavily marketed but legitimate
Get quotes from at least 3 carriers. The rate variation between insurers can be 20-40% for the exact same coverage on the same person.
Bottom line
Use DIME to set the target. Buy 20-30 year level term from a reputable carrier. Reassess every 5-7 years as life changes (more kids, paid-off mortgage, etc.). Skip whole life unless you have specific estate-planning advice from a fiduciary planner. The whole process for most people is one of the higher-leverage 90 minutes of financial work they’ll ever do.
