What Is Term Life Insurance and How Does It Work?

Term life insurance pays a death benefit to the beneficiaries you name if you die during the policy term. Terms last 10, 20 or 30 years for most policies; some go up to 40. Your premium (the monthly or annual payment that keeps coverage active) is fixed from day one and won't change. If you're alive when the term ends, coverage stops with no payout made.

Term life doesn't build savings or accumulate value of any kind. You're paying for financial coverage and nothing else. A healthy 30-year-old woman pays $31 a month for $500,000 in 20-year coverage, a fraction of what permanent life insurance costs for the same amount.

Term life locks in your rate at the time of application. You pick the coverage amount and the number of years you want the policy to run. That premium holds from year one through your final payment. A $500,000, 20-year policy costs the same in year one as it does in year 19.

Most insurers ask health questions when you apply, and some require a medical exam based on your age and coverage amount. Once approved, you sign the policy and pay your first premium to activate coverage.  

If you die while the policy is active, the insurer pays your beneficiaries (the people you designated to receive the payout) the full death benefit, tax-free. If you outlive the term, coverage ends. You don't get your premiums back unless the policy includes a return-of-premium rider. From there, you can renew at a higher rate based on your current age, convert to permanent coverage before the term ends, or let the policy lapse if you no longer need it.  

For instance, a healthy 40-year-old woman buys a 20-year, $500,000 policy. If she dies in year 12, her beneficiaries collect the full $500,000 tax-free. If she's alive when the term ends at 60, coverage stops. She can then renew at a higher rate, convert to a permanent policy if her policy includes that option (most do, up to age 65 or 70), or walk away if she no longer needs coverage.

Term life insurance costs five to 10 times less than whole life for the same coverage amount. A 40-year-old woman pays $47 (women) to $59 (men) a month for a 20-year, $500,000 term policy; the same coverage in whole life costs $540 (women) to $574 (men) a month. 

Age and gender affect your rate the most, and term length adds to the difference. The younger and healthier you are when you apply, the less you'll pay for the entire term.

Rates climb steadily through your 30s and 40s, then jump sharply after 50. Insurers price term life using actuarial mortality tables, the statistical models that estimate how likely someone is to die during the policy term. That risk accelerates faster in your 50s and 60s than in earlier decades.   

A 40-year-old woman, for example, pays $47 a month for a 20-year, $500,000 policy. At 50, that same coverage costs $102, a 117% increase in 10 years. A 30-year-old who waits until 40 to buy pays $3,800 more over the life of a 20-year term.  

Smoking raises the rate for the same age and coverage. A 40-year-old female smoker averages $148. For men, the smoker rate averages $194. The gap is $101 per month for women and $153 per month for men.

Term life is the most affordable way to get substantial financial coverage. Its primary limitation is also what keeps the cost low: it expires.

Calculate how much coverage your family needs to replace your income, pay off debts and cover major expenses. A common starting point is 10 times your annual income. From there, adjust based on your outstanding mortgage balance, other debts like student loans and credit cards, your children's future college costs, and the years remaining until your dependents are financially independent.

Another way to estimate coverage is the DIME method, which adds up four specific numbers:

• Debt: Total your non-mortgage debts, such as credit cards, student loans and car loans.
• Income: Multiply your annual income by the number of years your family would need support.
• Mortgage: Add your remaining mortgage balance.
• Education: Add estimated future college costs for each child.

Add those four numbers. The total is your coverage floor, not your ceiling. Use MoneyGeek's life insurance calculator for a personalized estimate.

Pick a term that covers how long your financial obligations will last.

• New parents and young families: A 30-year term covers you until your children are financially independent and outlasts most 30-year mortgages.
• Homeowners in peak earning years: Match the term to your mortgage. A 20-year term covers what's left on a loan taken out in your 30s or 40s.
• Near-retirees with a shrinking mortgage and grown children: A 10-year term covers the final stretch before retirement, when income-replacement needs are at their lowest.
• Empty nesters with no debt and no dependents: A new term policy isn't necessary at this stage. Permanent coverage or a final-expense policy is the better fit if your goal has shifted to estate planning or covering funeral costs.

Term life and whole life insurance differ on two points: how long they cover you and whether they build cash value (a savings component that grows inside the policy over time, which you can borrow against or withdraw). Term covers you for a set number of years and builds no cash value. Whole life covers you for your entire life as long as you pay premiums, and part of each payment builds that cash value over time.

The monthly cost gap is the biggest practical factor for most buyers. On average, whole life insurance costs $493 per month for women and $515 per month for men. 

A common financial approach is to buy term and invest the monthly savings rather than pay for riders to add coverage. The argument for whole life is the cash value component: savings that build inside the policy over time, available to borrow against or withdraw. Coverage also doesn't expire as long as premiums are paid.  

For most buyers with a mortgage, young children and an income to replace, term is the practical answer.

For anyone with dependents or debt, yes. A 30-year-old woman in good health pays $31 a month for $500,000 of 20-year coverage. If she dies in year 11, her family collects the full amount tax-free. That covers a mortgage payoff, years of lost income and childcare costs. If she outlives the policy, she's paid $7,440 over 20 years for coverage she didn't need to use. That's the trade-off.

Term life isn't worth buying if you have no dependents, no debt and have enough savings to cover final expenses without burdening anyone. At that point, the premium doesn't serve a purpose.

Term life gives you the most coverage for the least cost. Rates increase with age, and health problems can make coverage more expensive or harder to get. Applying earlier costs less.  

Choose a 20- or 30-year level term policy with a death benefit large enough to replace your income and pay off major debts. If your situation changes, most policies let you convert to permanent coverage before the term ends, without a new medical exam.
