Term vs Whole Life Insurance Calculator
Compare term and whole life insurance with the "buy term and invest the difference" method over a multi-year horizon. Educational, not financial advice. Runs in your browser.
After 30 years, from your policy illustration.
This models the classic “buy term and invest the difference” comparison: it grows the annual premium gap (whole − term) at your assumed return and compares the result to your whole-life policy’s projected cash value. Term wins on cost and pure investing in most steady-return scenarios; whole life offers permanent coverage, forced savings, and tax-deferred cash value that term lacks. Real outcomes depend on actual returns, dividends, policy fees, and discipline to actually invest the difference. Not financial advice — consult a professional. Everything runs in your browser.
About this tool
Term and whole life insurance solve overlapping but different problems, and the choice between them is one of the most debated questions in personal finance. Term life covers you for a set period (say 20 or 30 years) for a low premium and pays out only if you die during the term — it is pure, temporary protection with no savings component. Whole life is permanent: it never expires as long as premiums are paid, and a portion of each much-larger premium builds tax-deferred 'cash value' you can borrow against, but you pay many times more for the same death benefit. The classic framework for comparing them, popularized by consumer advocates, is 'buy term and invest the difference': purchase cheaper term insurance and invest the premium you would have spent on whole life, on the theory that a disciplined investor ends up with more money than the policy's cash value. This calculator runs that comparison. It takes the annual premium gap between whole and term, grows it at an assumed investment return as an ordinary annuity over your chosen horizon, and compares the result to the whole-life policy's projected cash value (from your policy illustration). In most steady-return scenarios the invest-the-difference side comes out ahead, which is why term plus investing is the standard recommendation for people whose insurance need is temporary (covering working years, a mortgage, child-rearing). But whole life has genuine uses the math here cannot fully capture: permanent coverage for lifelong dependents or estate liquidity, forced savings for those who would not invest the difference, and certain tax and creditor-protection features. Real results hinge on actual returns, policy dividends and fees, and whether you truly invest the difference. This is educational and not financial advice — consult a licensed professional.

Frequently asked questions
- What is "buy term and invest the difference"?
- A strategy of buying lower-cost term insurance and investing the premium you would otherwise pay for whole life. The idea is that the invested difference often grows to more than a whole-life policy's cash value, while still providing coverage during the term.
- How does this calculator compare the two?
- It grows the annual premium gap (whole − term) at your assumed return over the period as an annuity, then compares that future value to the whole-life policy's projected cash value. A positive difference favors term-plus-investing.
- When does whole life make sense despite the cost?
- For permanent needs — a lifelong dependent, estate liquidity, or business succession — and for people who value forced savings, guaranteed cash value, or its tax and creditor-protection features, and who would not reliably invest the difference themselves.
- Why does term usually win the math?
- Whole life bundles insurance with a conservative, fee-laden savings vehicle. Separating them — cheap term plus a low-cost investment account — typically produces higher returns over long horizons, assuming you actually invest the savings.
- What does the comparison leave out?
- Actual (not assumed) investment returns, whole-life dividends and internal fees, the tax treatment of cash value and death benefit, and behavioral discipline. Use your policy illustration for the cash value and treat the result as directional.
