How much life insurance do you really need?
There's no single "right" answer, but the DIME method gives you a structured framework that's more accurate than the popular "10× your income" rule of thumb. DIME stands for Debt, Income, Mortgage, Education — the four financial obligations your policy should cover if you die prematurely.
The DIME breakdown
- Debt: All non-mortgage debt — credit cards, student loans, auto loans, personal loans.
- Income replacement: Enough to replace 70% of your income for the years your dependents need it (typically until the youngest child is 18, or until your spouse reaches retirement age).
- Mortgage payoff: The outstanding balance so your family can stay in the home.
- Education: Estimated college costs per child (currently $80,000–$150,000 for a 4-year public university including room and board).
Term vs whole life
For 95% of families, term life insurance is the right answer — it covers you for a fixed term (10, 20, or 30 years) when your dependents actually need it, and costs 5–10× less than whole life. Whole life policies mix insurance with an investment component that almost always underperforms a simple index fund strategy.
Get quotes from at least three insurers — life insurance rates vary by 30–50% between carriers for identical coverage. Independent brokers (not captive agents) can shop multiple carriers at once.
Frequently asked questions
Term vs whole life — which is better?
For 95% of families, term life is the right answer. Term covers you for a fixed period (10, 20, 30 years) when your dependents actually need it, and costs 5-10× less than whole life. Whole life mixes insurance with a poor-performing investment — avoid it unless you have specific estate planning needs.
How long should my term be?
Long enough to cover your dependents until they're financially independent. Common rules: until your youngest child is 22, until your mortgage is paid off, or until you plan to retire. 20-30 year terms are most common.
What medical exam is required?
Most policies require a free medical exam (blood draw, urine sample, blood pressure, height/weight, medical history questionnaire). 'No-exam' policies exist but cost 20-50% more. Smokers pay 2-4× more than non-smokers.
Should I get life insurance through my employer?
Employer-provided life insurance is a nice benefit but typically limited to 1-2× salary — far less than most families need. Plus, you lose coverage if you change jobs. Buy an individual policy for your core need; use employer coverage as a supplement.
Does life insurance payout get taxed?
Generally no — death benefits are income-tax-free to beneficiaries. However, if the policy is in your estate and your estate exceeds the federal estate tax exemption ($13.99 million per individual in 2025), it may be subject to estate tax. Setting up an irrevocable life insurance trust (ILIT) avoids this.
What happens if I outlive my term policy?
Coverage ends. Most term policies offer 'level term' (rate stays flat for the term), then become annually renewable at much higher rates. Some offer 'return of premium' riders that refund premiums if you outlive the term — but the rider costs 30-50% more.
Can I have multiple life insurance policies?
Yes. Many people 'ladder' policies — e.g., a 30-year $500,000 policy plus a 20-year $250,000 policy plus a 10-year $250,000 policy. This matches coverage to declining needs (mortgage payoff, kids growing up) and costs less than one large 30-year policy.
Glossary of key terms
- Term Life Insurance
- Coverage for a fixed period (10, 20, 30 years). Pays out only if you die during the term. No cash value.
- Whole Life Insurance
- Permanent coverage that builds cash value. Premiums are 5-10× higher than term. Almost always a poor investment.
- Underwriting
- The insurer's process of assessing your risk before issuing a policy. Includes medical exam, history review, sometimes lifestyle questions.
- Beneficiary
- The person(s) who receive the death benefit. Choose primary and contingent beneficiaries. Update after major life events.
- Rider
- An optional add-on to a policy — e.g., waiver of premium, accidental death, return of premium, child term rider.
Common mistakes to avoid
- Buying whole life insurance when term would suffice — wastes thousands per year in premiums
- Naming your estate as beneficiary — subjects the payout to probate and possibly estate tax
- Not updating beneficiaries after divorce, marriage, or children
- Under-insuring — $250,000 sounds like a lot but barely replaces 3-4 years of median income
- Lying on the application — insurers can deny payout if material misrepresentation is found, even years later
Pro tips
- Get quotes from at least 3-5 insurers — rates vary 30-50% for identical coverage.
- Buy term life when you're young and healthy — rates lock in for the full term and increase dramatically with age.
- Ladder policies: e.g., $500K/30yr + $250K/20yr + $250K/10yr — matches coverage to declining needs and saves money.
- If you have significant assets ($5M+), consider an irrevocable life insurance trust (ILIT) to keep the death benefit out of your taxable estate.
- Quit smoking at least 12 months before applying — non-smoker rates are 2-4× cheaper. Some insurers require 5 years tobacco-free.
