Compound Interest Calculator
Enter the values you know. The value left out will be automatically calculated using the formula : $A = P(1 + \frac{r}{n})^{nt}$ and displayed.
Compound Interest Formula
| A | Total accrued amount i.e. (principal + interest) |
| P | Principal Amount |
| I | Interest Amount |
| 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.
