This tutorial shows how present value and future value are related using the example below:
In the example shown, Years, Compounding periods, and Interest rate are linked in columns C and F like this:
F5=C9 F6=C6 F7=C7 F8=C8
The formula to calculate future value in C9 is:
The formula to calculate present value in F9 is:
No matter how years, compounding periods, or rate are changed, C5 will equal F9 and C9 will equal F5.
