Compounding is a very powerful concept in financial planning. You can see it at work on bank fixed deposits and on your bank savings account.

The compound interest formula for periodic compounding is derived from the following function:

Where,
A(t) = Amount function
A(0) = Principal amount (Initial Investment)
t = Total time in years
n = Number of compounding periods per year
r = Nominal annual interest rate
⌊nt⌋ means that nt is rounded down to the nearest integer.
