Compare term life plus investing the premium difference with whole-life guaranteed and illustrated cash value, fees, taxes, premium schedules, and death-benefit timing.

Death-year scenario

Term coverage is included only if this year is within the selected term.

The death comparison adds the investment account to an active term benefit. Whole-life cash value is not added separately unless the policy illustration explicitly says it is.

Which choice builds more value?

Buying term and investing is ahead by $90,717

Value after 20 years: term plus investments $215,717 vs projected whole-life cash value $125,000. The whole-life projection is not guaranteed.

Term + investments after 20 years

$215,717

$110,400 contributed; modeled net return 6.30%.

Guaranteed whole-life value

$70,000

Difference versus invested balance: $145,717.

Projected whole-life value (not guaranteed)

$125,000

Difference versus invested balance: $90,717.

Investment return needed to tie

1.93%

Gross annual return before the entered fee and tax drag.

If death happens in year 15

Term + investment is higher by $135,212

Term + investments: $635,212. Whole life: $500,000.

Total premiums paid

$9,600 / $120,000

Term first; whole life second. These are cash outflows, not account values.

How this calculator works

The model invests the positive monthly difference between scheduled whole-life and term premiums. After the term expires, it continues investing the avoided whole-life premium through the selected whole-life pay period. Returns compound monthly after investment fees and estimated tax drag.

Whole-life cash value cannot be reconstructed reliably from premium alone. The guaranteed and current illustrated values therefore come directly from your policy document. The living-value result is separate from the death-benefit scenario.

Life insurance comparison guide

Test buy-term-and-invest-the-difference against a policy illustration

Term and whole life solve the same protection need in different ways. Term provides coverage for a stated period; whole life is designed for lifetime coverage and builds cash value.

A fair comparison uses equal death benefits, the real premium schedule, policy-specific guaranteed and non-guaranteed values, and an investment return after fees and taxes.

How to use this tool

  1. Match the death benefit

    Start with comparable coverage amounts so price differences do not reflect different protection.

  2. Copy the illustration

    Use cash values from the exact policy year and distinguish guaranteed from current illustrated values.

  3. Model realistic investment drag

    Subtract fund expenses and any expected annual tax drag from the gross return scenario.

  4. Test death timing

    Move the death year before and after the term expiration to see when coverage changes the result.

Guaranteed and illustrated values are different

Whole-life guarantees are contractual when required premiums are paid. Dividends, credited rates, and non-guaranteed illustration columns can change. Compare the investment account with both figures rather than treating the current illustration as certain.

What the model includes

  • Monthly investing of the positive premium difference
  • Term expiration and limited-pay whole-life schedules
  • Investment expenses and estimated tax drag
  • Living-value comparison at a common horizon
  • Death benefit plus investment balance in a chosen year

Questions to ask before replacing coverage

New underwriting may change the price or eligibility. A replacement can restart surrender-charge periods, contestability provisions, and acquisition expenses. Never cancel existing coverage until replacement coverage is active and reviewed.

Life insurance contracts, taxes, surrender charges, loans, dividends, underwriting, and estate needs vary. This tool compares entered cash flows and is not insurance, tax, legal, or investment advice. Do not replace coverage based only on this estimate.

Frequently asked questions

What does buy term and invest the difference mean?

It means purchasing lower-cost term insurance for the protection need and regularly investing the premium difference instead of using a cash-value policy.

Is whole-life cash value paid on top of the death benefit?

Usually the insurer retains cash value and pays the stated death benefit, though policy riders and structures differ. This calculator does not add cash value to the whole-life death benefit unless you enter a larger benefit that reflects the contract.

What investment return should I use?

Use multiple scenarios after fund expenses and taxes. The required-return result shows the gross return needed to equal the entered illustrated cash value; it is not a forecast.

Can this calculator evaluate an IUL or variable life policy?

It can compare entered values, but it does not model caps, participation rates, cost-of-insurance changes, loans, lapse risk, or subaccount charges. Use the carrier’s guaranteed and non-guaranteed ledgers and review them with a qualified professional.
