Term vs Whole Life Insurance: Side-by-Side Calculator

Term life covers a set number of years for a lower premium. Whole life lasts for life and builds cash value, for a much higher premium. The honest comparison uses your own quotes, so this calculator asks for both premiums and shows what the difference could grow to if you invested it.

Term and whole life at a glance

Term life

How long it lasts
A set term. It pays only if you die during that term.
Cash value
Generally none.
Cost
Lower at the start. Renewing after the term usually costs more, and some policies stop renewing at a certain age.
Often suits
A need with an end date: children growing up, a mortgage being paid down.

Whole life

How long it lasts
For life, as long as premiums are paid.
Cash value
Builds over time; the policy illustration shows how much.
Cost
Higher, because part of each premium funds the cash value.
Often suits
A need that never ends, such as final expenses, a lifelong dependent or estate plans.

Descriptions follow NAIC consumer guidance on term and cash value life insurance.

Is term or whole life insurance better?

Neither in general. Term usually costs far less for the same death benefit and suits a need that ends, such as raising children. Whole life suits a need that lasts for life, or someone who values a guaranteed policy and cash value over the lower premium. Which fits depends on how long your family needs the cover and what you can keep paying.

Your two quotes

Match the term length you were quoted.
Your assumption, after fees. Not a forecast.
Optional. Use the guaranteed column of the insurer’s illustration for a cautious view.

NAIC’s own example, run through the calculator

NAIC’s consumer guide uses a 35-year-old buying a $100,000 death benefit, with a whole life premium of $1,800 a year against a term premium of $250. Its premiums are an illustration, not current market prices. The table assumes the $250 term premium stays level for 20 years and the $1,550 difference is invested every year.

Return on the differenceTerm premiums, 20 yearsWhole life premiums, 20 yearsInvested difference after 20 years
3% a year$5,000$36,000$42,899
5% a year$5,000$36,000$53,815
7% a year$5,000$36,000$67,991

To finish the comparison, set the invested pot against the whole life policy’s cash value at year 20 from its illustration.

Two things that table cannot show matter just as much. After 20 years the term buyer has the pot but no cover, and buying new cover at 55 costs more and depends on health. The whole life buyer still has a $100,000 death benefit. NAIC also points out that the plan only works if the difference really is invested, not spent.

What this comparison leaves out

  • Taxes on investment gains, and how a policy’s cash value and death benefit are taxed. Check with a tax professional.
  • Rising term premiums on renewal, conversion options, and riders.
  • Policy loans, surrender charges and dividends on participating whole life policies.
  • Your health. If it changes, new cover may cost more or not be available.

Before buying either, read the policy illustration and ask a licensed agent to explain the guaranteed and non-guaranteed columns.

Common questions

Can I switch from term to whole life later?

Many term policies can be converted to a cash value policy during a conversion period, even if your health has changed, according to NAIC. The new premium will be higher. Check the conversion terms before you buy the term policy.

How much cover should I compare?

Work out the amount first, then compare policy types for that amount. The full coverage needs analysis runs three methods side by side.

How long a term should I quote?

Long enough to cover the years your family relies on your income. The guide how long term life insurance should be sets out a timeline method.
