Whole life cash value typically lags 'buy term + invest the difference' by 30-60% over 20 years. Numbers approximate; actual rates vary by carrier and health.
Term and whole life solve different problems, and the price gap is enormous — whole life often costs 5–15× more for the same death benefit. This calculator puts them side by side over 20–30 years so you can see exactly what the extra premium buys.
It also models the classic "buy term and invest the difference" strategy: what happens if you buy cheaper term and invest the premium savings instead of paying for whole life’s cash value.
How this calculator works
The calculator projects total premiums paid for a term policy versus a whole life policy at the same death benefit, then grows whole life’s cash value at a typical guaranteed rate. In parallel it invests the premium difference (whole life minus term) at an assumed market return, so you can compare whole life’s cash value against the "invest the difference" portfolio at the end of the period.
Assumptions and data behind the estimate
The comparison projects total premiums for a term and a whole life policy at the same death benefit, grows whole life cash value at a conservative guaranteed rate, and separately invests the premium difference at a market return you set — the standard “buy term and invest the difference” test. Results depend heavily on the return assumption and on dividends, which are not guaranteed. It is an illustration for comparison, not a policy quote.
What affects the number
- Death benefit and your age/health (which set both premiums)
- Term length — 20 vs 30 years changes the comparison window
- Whole life’s guaranteed cash-value growth rate
- The market return you assume for investing the difference
- How long you actually need coverage — lifelong vs. only while you have dependents
Frequently asked questions
Is whole life insurance worth it?
For most people, no — term covers your highest-need years far cheaper, and investing the difference usually beats whole life’s cash value. Whole life makes sense for estate planning, a lifelong dependent, or guaranteed lifetime coverage. The calculator shows the math for your numbers.
What does "buy term and invest the difference" mean?
You buy lower-cost term insurance and invest the money you’d have spent on whole life premiums. Over 20–30 years that invested difference often grows larger than whole life’s cash value, while still covering you during the years it matters most.
Why is whole life so much more expensive than term?
Term only pays if you die during the term, so most policies never pay out and premiums stay low. Whole life is permanent, builds cash value, and is guaranteed to pay eventually — so it costs far more.
Can I switch from whole life to term?
Yes, but compare carefully. You may lose accumulated cash value, and a new term policy is priced at your current (older) age and health. Run both scenarios before surrendering a policy.
