Term life insurance covers you for a set period, such as 20 or 30 years, and pays out only if you die during that time. Whole life insurance covers you for your whole life and builds a cash value, but costs many times more, often 5 to 15 times as much for the same death benefit. For most families who just need to replace their income, term is the better fit.
Side-by-side comparison
| Term life | Whole life | |
|---|---|---|
| How long it lasts | 10 to 30 years | Your whole life |
| Cost | Low | High |
| Cash value | None | Grows slowly at a guaranteed rate |
| Premiums | Fixed for the term | Fixed for life |
| Best for | Replacing income while kids are young or a mortgage is unpaid | Lifelong needs, estate planning, special-needs dependents |

How term life works
You pick an amount (often 10 to 12 times your income) and a length that matches your biggest obligations, like the years until your youngest child finishes school or your mortgage is paid off. If you outlive the term, coverage ends and nothing is paid. Many policies can be converted to permanent coverage without a new medical exam.
How whole life works
Part of each premium pays for the insurance, and part builds a cash value that grows tax-deferred. You can borrow against the cash value, but unpaid loans reduce the death benefit. In the early years most of your premium goes to costs and commissions, so the cash value builds slowly, and cancelling early often means getting back less than you paid.
“Buy term and invest the difference”
A popular strategy is to buy cheaper term coverage and invest the money you save in a 401(k), a Roth IRA or low-cost index funds. Over 20 to 30 years, that usually builds more wealth than whole life’s cash value, as long as you actually invest the difference.
When whole life can make sense
- You have a lifelong dependent, such as a child with special needs.
- You have a large estate and want money to pay estate taxes or equalize an inheritance.
- You have already maxed out your tax-advantaged retirement accounts.
How much life insurance do you need?
Add up your debts, future costs such as college, and the years of income your family would need, then subtract savings and existing coverage. Many workplaces offer one to two times your salary, which is usually not enough on its own. Make sure your emergency fund is in place too.

Frequently asked questions
What happens when term life ends?
Coverage stops. You can often renew at a much higher price or convert to a permanent policy.
Is whole life a good investment?
Usually not on its own. Its returns tend to be lower than a diversified portfolio after fees.
Can I have both?
Yes. Some people use a small whole life policy for final expenses and a larger term policy for income replacement.
