In case your capital generated now could be $100 placed within the a bank saving membership that’s to make focus at the 5%, than just P = $a hundred and you can r = 0.05. Under these standards, F step 1 = $105, extent to get obtained in one 12 months.

This new $a hundred establish expenses is called the current property value the newest $105 total end up being acquired in one season. It is very known as the discount value of tomorrow $105 acknowledgment.
