Compare term life insurance quotes
Term life premiums vary a lot between insurers for the same coverage. Comparing several quotes for level term can cut your cost meaningfully — leaving more to invest. Want a faith-aligned option? See our halal life-cover guide below.
Estimate your coverage need →How the term vs whole life calculator works
The comparison is simple and deliberately honest. The total premium you pay over the term for each option is just the monthly premium times twelve, times the number of years:
Total cost = monthly premium × 12 × years
Whole life usually costs far more per month than term. The idea behind "buy term and invest the difference" is to buy the cheaper term policy and invest the monthly gap. We compound that gap monthly using your expected annual return:
FV = D · [ (1 + r)n − 1 ] / r
where D is the monthly difference (whole-life premium − term premium), r is the monthly rate (annual return ÷ 12) and n is the number of months (years × 12). The headline figure is that future value at the end of the term. Buying term and investing the difference typically leaves you with more money — but remember the honest trade-off: whole life gives permanent coverage and builds cash value that term does not, and those real values vary by policy. This tool shows the premiums and the hypothetical investment only.
Frequently asked questions
What does "buy term and invest the difference" mean?
You buy cheaper term life instead of pricey whole life, then invest the monthly premium difference. Over the term, those savings can compound — this tool estimates the future value at your assumed return.
Is term or whole life insurance better?
Neither is universally better. Term is far cheaper for a fixed period, so investing the difference often wins on money. Whole life costs much more but gives permanent coverage and cash value you keep for life. It depends on your goals, horizon and discipline to actually invest the savings.
Does this account for whole life cash value and dividends?
No. This is illustrative only. It shows premiums paid and the hypothetical value of investing the difference, but does not model a real policy's cash value, dividends or surrender value — those vary widely and are not guaranteed.
What return should I assume?
Returns are never guaranteed. A long-run diversified stock average is often cited around 6–8% before inflation and fees, but yours could be higher, lower or negative. Try a few rates to see how sensitive the result is.
