Term life insurance covers you for a set period (say 20 or 30 years) at a low cost; whole life covers you for your entire life and builds cash value, but costs many times more. For most families, term life provides the protection they actually need at a price they can afford.
Quick verdict
Buy term life if your goal is to protect your family while they depend on your income — it's cheap and does exactly that. Consider whole life only for specific needs: lifelong dependents, estate-planning liquidity, or a maxed-out tax-advantaged saver who wants another tax-deferred bucket. For most people, "buy term and invest the difference" wins.

Why term works for most people
The main reason to carry life insurance is to replace your income if you die while others depend on it — typically while you're raising children or paying off a mortgage. Term life matches that need exactly: a large death benefit for the 20–30 years it matters, at a low premium. Once the kids are grown, the mortgage is paid and you've built savings, you may not need coverage at all.
When whole life can make sense
Whole life isn't a scam — it's just the wrong tool for most buyers. It can fit people with a lifelong dependent (such as a child with special needs), those who need guaranteed liquidity to cover estate taxes, or high earners who have already maxed every tax-advantaged account and want another tax-deferred place to put money. For everyone else, the high premiums usually outweigh the benefits.
"Buy term and invest the difference"
The classic strategy: buy cheap term insurance and invest the large premium difference into low-cost index funds, a 401(k) or an IRA. Over decades, that invested difference often grows to more than whole life's cash value — and you keep full control of it.

Frequently asked questions
Is term or whole life insurance better?
For most families, term is better — a fraction of the cost for the same death benefit, covering the years your family depends on your income. Whole life suits a minority with estate-planning or lifelong-dependent needs.
Why is whole life insurance so much more expensive?
It covers your entire life (so it will eventually pay out) and bundles a cash-value savings component — often making premiums 5 to 15 times higher than term for the same coverage.
What is "buy term and invest the difference"?
Buying cheap term insurance and investing the savings versus whole life into low-cost funds. Over time this often builds more wealth than whole life's cash value while still protecting your family.
How much life insurance do I need?
A common guideline is 10–12× your annual income, adjusted for debts, how long dependents need support, and existing savings. A term policy covering those years is usually enough.
