Buy-term-and-invest-the-difference compares the low cost of term insurance with permanent insurance by investing the premium difference. This shows what that side fund could grow to over your horizon. Permanent policies build their own cash value and last for life, so the right choice depends on how long you need coverage and your discipline to invest the difference. Illustrative, not advice.

Term vs. Permanent Life Insurance

Compares buying term life insurance and investing the premium savings against paying higher whole life premiums, projecting the side fund you could build over time.

The buy term and invest the difference idea

Term insurance covers a set number of years at a much lower premium than permanent whole life, which builds cash value but costs far more. The strategy invests the annual difference between the two premiums at an assumed return, showing the separate side fund you accumulate. Over a long horizon that fund can grow to a meaningful amount, which is the core argument for choosing term. This calculator isolates the premium gap and compounds it, so you can see the trade-off clearly.

What the comparison leaves out

Whole life provides lifelong coverage, a guaranteed cash value, and some tax advantages that a simple side fund does not replicate. Term coverage ends when the term expires, and renewing later can be costly or unavailable. Investment returns are not guaranteed, and the side fund is exposed to market risk while whole life values are more stable. Use this as an illustration, not financial advice, and weigh your health, goals, and need for permanent coverage.

How to use it

  1. Enter the annual term life premium.
  2. Enter the annual whole life premium.
  3. Enter your expected investment return.
  4. Enter the number of years, then review the projected side fund.

Frequently asked questions

Why is term insurance so much cheaper?

Term only covers a fixed period and builds no cash value, so nearly all of the premium pays for pure death benefit protection. Whole life costs more because it lasts your whole life and accumulates value.

Is the side fund guaranteed to beat whole life?

No, the side fund depends on actual investment returns, which vary and can be negative in some years. Whole life offers guarantees that this comparison does not capture.

What happens when the term ends?

Coverage stops unless you renew or convert, and premiums at older ages or with health changes can be much higher. Many people plan for term to end once savings and obligations have shrunk.
