About Term vs. Whole Life Insurance Calculator

The Term vs. Whole Life Insurance Calculator models the classic financial strategy: "Buy Term and Invest the Difference", demonstrating how buying inexpensive term insurance and investing the premium savings in index funds yields vastly superior wealth compared to whole life cash value.

Formula & Mathematical Calculation

Monthly Premium Difference = Whole Life Monthly Premium - Term Life Monthly Premium

BTID Wealth in Year 30 = Premium Difference × [ (( 1 + r/12 )^360 - 1) / (r/12) ]

Calculation Example

$500k Coverage (Age 30): Whole Life ($400/mo) = $240k Cash Value at Year 30. Term ($35/mo) + Invest Difference ($365/mo @ 8% return) = $544,000 Investment Portfolio ($304,000 MORE WEALTH than whole life!).

Frequently Asked Questions

It takes the monthly premium difference between a whole life quote and a term quote, then projects what that difference would grow to if you bought term instead and invested the savings at your assumed annual return for the number of years you enter.

Whole life premiums are typically much higher than comparable term premiums. The tool treats the monthly difference as an amount you could redirect into an investment, and compounds that monthly amount at your assumed return over the chosen horizon.

The result assumes the premium difference stays constant every month, your investment return is fixed for the whole period, and there are no taxes, fees, or insurance policy changes. Real investing performance and term renewals will deviate from these idealized numbers.

No. It only quantifies the growth potential of the premium difference under your inputs. Choosing between term and whole life also depends on coverage needs, cash-flow preferences, guarantees, and estate goals that are outside this projection.
