Compound Interest Formulas & Calculation Steps
View All Math Formulas Handbook →Future Value Formula ($A$)
Total accrued amount with compounding:
$$ A = P \left(1 + \frac{r}{n}\right)^{nt} $$
Total interest earned:
$$ I = A - P = P \left[\left(1 + \frac{r}{n}\right)^{nt} - 1\right] $$
Continuous Compounding Formula
When compounding frequency approaches infinity:
$$ A = P \times e^{rt} $$
Effective annual rate (EAR):
$$ \text{EAR} = \left(1 + \frac{r}{n}\right)^n - 1 $$
