What is the difference between term life and whole life insurance?

Term life covers you for a set period (e.g., 10–30 years) and pays a death benefit only if you die during that term. Whole life covers you for your entire lifetime and builds cash value, but premiums are substantially higher.

How term life insurance works

A term life policy provides a death benefit if the insured dies within a specified period — commonly 10, 15, 20, or 30 years. If the insured outlives the term, coverage ends and no benefit is paid (though some policies offer renewal or conversion). Because term policies build no cash value, the premium goes entirely toward the death benefit, making term the lowest-cost option per dollar of coverage. The III describes term life as providing the greatest amount of coverage for the lowest initial premium.

How whole life insurance works

Whole life (a form of permanent life insurance) remains in force for the policyholder's entire lifetime, provided premiums are paid. In addition to the death benefit, the policy accumulates cash value over time on a tax-deferred basis. Premiums are fixed but significantly higher than term premiums for the same face amount. The III overview of permanent life types covers the full spectrum.

Key differences at a glance

Coverage duration: Term = fixed period; whole life = lifetime (as long as premiums are paid).
Cash value: Term builds none; whole life accumulates cash value over time.
Premium cost: Term premiums are lower initially; whole life premiums are higher but fixed.
Premium stability: Term premiums can increase at renewal; whole life premiums are locked in at issue.
Tax treatment: Cash-value growth inside a whole life policy accumulates tax-deferred (consult a tax professional).

Key takeaways

Term life: fixed period, lower cost, no cash value — death benefit only if you die during the term.
Whole life: lifetime coverage, higher cost, builds cash value over time.
Term is often chosen for needs tied to a specific window (mortgage payoff, children reaching adulthood).
Neither type is universally 'better' — the right structure depends on your goals, budget, and time horizon.
