What this result means

Total term premiums paid: $7,200.

Choosing term life costs $7,200 in total premiums over the term vs. $96,000 for whole life — a savings of $88,800. If you invest the monthly premium difference at your assumed return, it would grow to approximately $192,743. For the whole life policy to break even financially, its cash value would need to exceed that amount. Consult a licensed insurance professional before making a policy decision.

How this is calculated

Term total = term_monthly_premium × term_length × 12. Whole total = whole_life_monthly_premium × term_length × 12. Opportunity cost = monthly_diff × ((1+r)^n − 1) / r, where r = annual_return / 12 and n = term_length × 12 (FV of annuity).

Term life and whole life insurance both pay a death benefit to your beneficiaries — but they work very differently, and choosing the wrong one can cost you tens of thousands of dollars over your lifetime.

Term life: pure protection. A term policy covers you for a set period — typically 10, 20, or 30 years — and pays a death benefit only if you die during that term. Premiums are fixed and dramatically lower than whole life. For a healthy 35-year-old, a 20-year $500,000 term policy often costs $25–$40/month. At the end of the term, the policy expires and you have no cash value.

Whole life: insurance plus savings. A whole life policy covers you for life (as long as premiums are paid) and builds a cash value component over time. That cash value grows at a guaranteed rate and can be borrowed against or surrendered. The trade-off is cost: the same $500,000 of coverage can cost $300–$500/month or more — 10 to 15 times higher than term.

Buy term, invest the difference. The classic personal finance strategy is to buy the cheapest term policy that meets your coverage needs and invest the premium savings in a diversified portfolio. At 7% annual return, $370/month invested over 20 years grows to roughly $228,000 — typically far more than the cash value in a comparable whole life policy. This strategy also gives you flexibility: you can stop, reduce, or redirect those savings at any time.

When whole life makes sense. Whole life is not always the wrong choice. It can be appropriate for high-net-worth individuals who have maximized all other tax-advantaged accounts, need permanent death benefit for estate liquidity, or are funding irrevocable life insurance trusts (ILITs). It may also be appropriate when term coverage is unavailable due to health conditions that make renewal impossible at term expiration.

The cash value hurdle. To justify the higher premium, a whole life policy's cash value must ultimately exceed what you would have accumulated by investing the premium difference yourself. This calculator shows you that hurdle so you can evaluate any whole life illustration against a realistic alternative. Always ask your insurer for a policy illustration and compare the guaranteed cash value column against the invested-difference figure shown here.

Assumptions

  • Premium estimates are illustrative; actual premiums depend on age, health, gender, tobacco use, and insurer.
  • The invested-difference calculation assumes consistent monthly contributions at the stated annual return — actual investment returns will vary.
  • No surrender charges, policy fees, or dividend participation are modeled for the whole life comparison.
  • Whole life cash value projections are not modeled; use the insurer-provided policy illustration for actual cash value figures.
  • This calculator does not constitute insurance or investment advice — consult a licensed insurance professional and a fiduciary financial advisor.

Frequently asked questions

›When should I choose whole life over term?

Whole life makes sense in a narrow set of scenarios: you need permanent coverage for estate planning (e.g., funding an ILIT or covering estate taxes), you have already maxed out 401(k), IRA, and other tax-advantaged accounts and want additional tax-deferred growth, or you have a dependant with a lifelong disability who will never be self-supporting. For the vast majority of people — especially those with a mortgage, young children, or income-dependent spouses — term life is the right product.

›Is whole life insurance a good investment?

Generally, no — not compared to investing the premium difference in a diversified index fund. Whole life cash value grows at guaranteed rates that have historically lagged market returns significantly. Surrender charges in early years can wipe out gains, and the insurance company takes a substantial spread. That said, the comparison is imperfect: whole life offers guarantees and tax-deferred growth, and for certain high-income individuals who have exhausted other tax shelters, it may have a role in a diversified financial plan.

›What happens at the end of my term policy?

When a term policy expires, your coverage ends and the insurer keeps all premiums paid — there is no cash value or refund (unless you purchased a 'return of premium' rider, which is significantly more expensive). You can often renew the policy annually, but premiums increase sharply with age. The better strategy is to plan for term expiration: ideally, by the time your term ends your mortgage is paid off, children are independent, and your investment portfolio is large enough to self-insure. If you still need coverage, apply for a new term policy before the old one expires, while you are still insurable at favorable rates.

›Can I convert my term policy to whole life later?

Many term policies include a conversion privilege that allows you to convert to a permanent policy without a new medical exam, typically before a certain age (often 65) or within the first 10–20 years of the term. This can be valuable if your health declines and you later need permanent coverage. Check your policy documents for conversion options and deadlines, and consider them when choosing a term carrier.

›How accurate are the default premium estimates?

The default premiums ($30/month term, $400/month whole life for $500,000 coverage) are representative industry estimates for a healthy 35-year-old non-smoker as of 2025, based on publicly available rate surveys. Actual premiums vary significantly by age, health, gender, tobacco use, and the specific insurer. Always get personalized quotes from at least three carriers before purchasing any policy. Use this calculator's inputs to plug in your actual quoted premiums for a precise comparison.
