Term life insurance gives you a death benefit for a fixed period at a low, predictable premium. A healthy 35-year-old pays roughly $29–$35/month for $500,000 in 20-year term coverage. Whole life is permanent, builds cash value, and costs 8–15 times more for the same death benefit — often $400–$500/month for the equivalent coverage.
Most financial planners favor term life for working families in their income-earning years. But there are specific situations where permanent coverage genuinely fits. The calculator below shows the actual numbers for your age and coverage amount so you can compare both before any conversation with an agent.

For most people, term life insurance is the clear winner on cost: a healthy 40-year-old woman can get a $500,000, 20-year term policy for roughly $28–$45/month in 2026, while comparable whole life coverage can cost 5–10× more. Term is designed to protect your family during the years you need it most (while you have dependents and a mortgage), whereas whole life builds cash value and lasts your lifetime — at a price. Use this calculator to compare the true cost difference and decide which fits your goals.
Term life covers you for a set period — 10, 20, or 30 years — at a fixed monthly premium. If you die during the term, your beneficiaries receive the full death benefit tax-free. If you outlive the term, the policy ends with no payout. No investment component, no cash value, no complexity. For healthy adults under 40, $500,000 in 20-year term coverage typically costs $20–$50/month — affordable protection for exactly the years when your family most depends on your income.
Whole life combines a death benefit with cash value that grows at a guaranteed rate (typically 2–4%) and accumulates tax-deferred. Coverage is permanent and premiums are fixed. The tradeoff is cost: premiums run 10–15 times higher than term for the same death benefit. A disciplined investor putting the monthly premium difference into a diversified index fund has historically earned 7–10% annually — building a significantly larger portfolio than the policy’s cash value over 20 years. The comparison table above runs those exact numbers for your age.
Whole life isn’t bad insurance — it’s often mismatched to the buyer. It genuinely fits in specific situations: high-net-worth estate planning where permanent coverage provides liquidity for estate taxes; business buy-sell agreements requiring a permanent death benefit; parents of a child with a lifelong disability who needs permanent coverage regardless of when the parent dies; and individuals who’ve fully maxed their 401(k), IRA, and HSA and want additional guaranteed, tax-deferred storage. For most working families with a mortgage, dependents, and standard income, the comparison table consistently favors term plus investing the difference — often by a substantial margin over 20 years.

Key insight: In every scenario, investing the premium difference at a modest 7% annual return produces a portfolio substantially larger than the whole life policy's cash value after 20 years. The gap widens the younger you start. This is the foundation of the “buy term and invest the difference” strategy endorsed by most fee-only financial planners.

The term vs. whole life decision is one of the most debated in personal finance, and the right answer genuinely depends on your full financial picture. If your primary need is income replacement for a defined period — the years until your mortgage is paid off, or until your youngest child is independent — the math almost always favors term life. But if you have estate planning goals, a business with succession needs, a child with a lifelong disability requiring permanent coverage, or you've already maxed all tax-advantaged investment accounts and want guaranteed tax-deferred growth, whole life or universal life products may merit a serious look. These cases are complex enough to warrant a fee-only financial planner who doesn't earn insurance commissions — they can model both paths objectively and show you the long-term financial comparison specific to your situation.
For straightforward term life purchases, an independent insurance agent or online comparison platform is entirely adequate. Get quotes from at least 3–4 carriers — the spread between the cheapest and most expensive carrier for identical coverage can exceed 40%. Pay attention to the financial strength ratings of any carrier you're considering (A.M. Best A or better is the standard benchmark) — a life insurance policy may need to pay a claim decades from now, so carrier solvency matters. If you're replacing an existing policy, never cancel the old policy until the new one is fully issued and in force; the conversion option in many existing term policies also has value worth evaluating before walking away.
