How It Works
Understanding compound interest

Compound Interest Formula:

A=P(1+rn)nt+PMT×(1+rn)nt1rnA = P\left(1 + \frac{r}{n}\right)^{nt} + PMT \times \frac{\left(1 + \frac{r}{n}\right)^{nt} - 1}{\frac{r}{n}}

A = Future value of investment

P = Principal amount (initial investment)

r = Annual interest rate (decimal)

n = Number of times interest is compounded per year

t = Number of years

PMT = Regular contribution amount

Compound interest allows your investment to grow exponentially over time. The more frequently interest is compounded, the more you earn. Regular contributions can significantly boost your returns.
