Term life insurance length calculator

Quick answer: The usual approach is to match the term to your longest financial obligation: until your youngest child is about 22, until the mortgage is paid, or until you stop relying on earned income. The calculator takes the longest of those and rounds up to a standard 10, 15, 20, 25 or 30-year term.

Why not just buy the longest term?

Longer terms cost more each year. If your biggest needs end sooner, a shorter term, or two smaller policies with different lengths (a “ladder”), can cover the same risk for less.

How much coverage?

Length is half the decision. Use the life insurance calculator to size the amount from income, debts, mortgage and education costs.

These are coverage-amount estimates, not quotes or advice. Premiums depend on age, health and insurer; a licensed agent or fee-only planner can review your situation.

Frequently asked questions

Is 20 or 30-year term life better?

Choose the term that outlasts your longest obligation. If your youngest is 8 and the mortgage has 15 years left, 15 years may be enough; a newborn and a new 30-year mortgage point to 25–30 years.

What happens when term life ends?

Coverage stops and premiums end. Many policies let you renew yearly at much higher rates or convert to permanent insurance by a set age.
