Interpretation

Over 20 years for $500,000 of coverage starting at age 35, term life premiums total about $8,400 while whole life totals about $100,800. Term life generally has lower premiums; whole life may include permanent coverage and cash value features that this estimate does not model in detail.

Recommendation

In this simplified comparison, term life plus investing the premium difference may grow faster than whole life premiums alone — but term life is not always the better fit. Whole life may suit estate planning, permanent coverage, or forced savings needs that are not modeled here. Compare actual policy quotes with a licensed professional.

Key risk

Whole life policies include fees and surrender charges. Term life is cheaper but expires unless renewed, often at higher rates.

Assumptions

Cash value mechanics are simplified. Fees, surrender charges, dividends, taxes, and policy details are not modeled. This is an educational estimate, not insurance advice.

Term life + investing the difference

Should you choose term life insurance or whole life insurance? This term vs whole life calculator compares total premium costs and estimates what you might accumulate if you buy term life and invest the monthly premium difference — a common educational comparison, not a substitute for personalized insurance advice.

How to use this calculator

  1. Enter the coverage amount you are comparing.
  2. Enter monthly premiums for term and whole life quotes you received.
  3. Enter term policy length, expected investment return, and years to compare.
  4. Review total costs, invested difference growth, and the educational recommendation.

Formula

Total premiums = Monthly premium × 12 × Comparison years (capped by term length). Invested difference = Future value of monthly (whole − term) premium savings at your expected return.

Example

A 35-year-old comparing $500,000 coverage with $35/month term and $420/month whole life over 20 years at 7% return may see term premiums around $8,400 while investing the $385/month difference could grow to a much larger amount — illustrating why many planners discuss buy term and invest the difference.
