Compound Interest Formula
|A||Total accrued amount i.e. (principal + interest)|
|R||Annual Nominal interest Rate in percent|
|r||Rate of interest per year r = R / 100|
|t||Time period involved in years(i.e. Calculation period)|
|n||Number of compounding periods per unit|
There is a special case when n -> ∞. This is called continuous compounding.
