How it works
Whole life insurance bundles two products: a death benefit that never expires and a savings account that grows inside the policy. Term insurance sells only the death benefit, for a fixed number of years, at a fraction of the price. The classic comparison — buy term and invest the difference — asks what happens if you buy the cheaper policy and put the premium gap into an index fund yourself. This calculator runs it with your own quotes. It takes the annual difference between the two premiums, compounds it at your assumed investment return for the years you need cover, and sets the result against the policy's cash value compounded at the illustrated rate. Both columns carry the same death benefit during the term, so the difference is purely what the savings portion becomes. Two things load the comparison against whole life. The internal growth rate is low, typically 2% to 4% guaranteed, because the insurer must hold reserves conservatively. And the first years of premium go largely to commission, so cash value in year three is often a fraction of what was paid in — which is why surrendering early recovers so little. Whole life still has a real case: cover that can never lapse, a forced savings habit, and estate planning where the death benefit is the point. The honest answer is that term wins on arithmetic while whole life wins on the specific problems permanent cover solves.Formula
Invested difference = FV(whole premium - term premium, return, years) | Compare against illustrated cash value
Tips
- Get both quotes for the same death benefit before running this — a comparison on mismatched coverage is meaningless.
- Ask the whole life agent for the guaranteed column of the illustration, not the projected one; only the guarantee is a promise.
- Level-term premiums are fixed for the term, then jump sharply — plan for the policy to end, not renew.
- The invested-difference plan only works if you actually invest the difference; if it becomes spending, whole life's forced saving may serve you better.
- Term laddering — several policies ending at different dates — matches falling cover needs and costs less than one long policy.
Frequently asked questions
Is term or whole life insurance better?
For most households needing cover during working years, term plus investing the difference produces more money, because term costs a fraction of whole life and index funds compound faster than policy cash value. Whole life is better when cover must never lapse, for estate liquidity, or for a business buy-sell agreement.
Why is whole life insurance so much more expensive?
Two reasons. It funds a death benefit priced for your whole life rather than a limited term, and it builds cash value, so part of every premium is a deposit. First-year commissions also come out of that premium, which is why early cash value is far below what you paid in.
What return does whole life cash value actually earn?
The guaranteed rate is typically 2% to 4%, and dividend-paying policies may credit more but do not promise it. Because early years carry front-loaded costs, the effective return over the first decade is often near zero or negative even when the long-run illustrated rate looks respectable.
What happens when my term policy expires?
Coverage simply ends and you stop paying. Most level-term policies allow annual renewal at sharply higher rates, and many include a conversion option that lets you switch to permanent coverage without a new medical exam — worth checking before you buy, because conversion rights matter if your health changes.
Can I cancel whole life and get my money back?
You can surrender the policy for its cash surrender value, which in the early years is substantially less than the premiums you paid because of surrender charges and front-loaded costs. Gains above your cost basis are taxable, and a 1035 exchange into another policy defers that tax.
