For example, consider an

This results in the (correctly) positive value of $189,836.64 (rounded).

THAT ONE doesn't jive with Excel's results...Don't know why either.

You are probably entering incorrect parameters. That calculator
matches my result above (rounded to the dollar) when I enter 12% for
"rate of return", select "compound monthly" and uncheckmark "make
deposits at the start of each period".

If you describe the parameters that you are entering, I might be able
to explain any difference that you see, if the above explanation does
not.

OK, here is my example I am using

Initial investment of $500.00
With $100 per month, every month.
At a return rate of exactly 10%
For a period of exactly 25 years.

thank you
