H5PikoHow the term vs whole life insurance calculator works
This calculator puts term and whole life side by side so you can see the real price of permanence. It estimates both monthly premiums for the age, coverage amount and term you choose, shows how much you would pay in total, and then estimates what the premium difference could grow to if invested instead.
What the numbers mean
The term premium comes from a simplified pricing curve for a healthy non-smoker. The whole life premium is estimated at about eight times the term premium, which reflects the typical gap seen in the market. Total paid is simply the monthly premium multiplied by the months in your chosen term. These are illustrations, not quotes, because real prices vary by insurer and health class.
The investing comparison
The most useful line is the future value of the monthly difference. The tool treats the gap between whole life and term as a monthly deposit and grows it at the return you enter, compounded monthly. The formula is the standard future value of an annuity: deposit x (((1 + r)^n - 1) / r), where r is the monthly rate and n is the number of months. A return of 6 percent is a reasonable long-run planning figure for a diversified portfolio, but it is not guaranteed, so try lower values such as 3 or 4 percent as well.
How to interpret the result
If the invested difference far exceeds the death benefit growth you would get from whole life cash value, term plus investing tends to be more efficient. But the comparison is not complete. Whole life provides a guaranteed death benefit that never expires and cash value that is protected from market losses. Term cover ends, and if you develop a health problem later you may not be able to buy a new policy. Conversion options on term policies can reduce this risk.
Questions to ask yourself
Will anyone depend on my income after the term ends? Will I actually invest the difference every month, rather than spend it? Do I have an estate or business need that requires permanent cover? Honest answers to these questions matter more than any single number from the tool.
Next steps
Change the term to 10, 20 and 30 years and compare, then request quotes for both types. Ask any agent for the guaranteed cash value schedule, not only the projected one, and check the insurer's financial strength rating before deciding.
