Compound Interest Formula

The compound interest is calculated using this formula:$$A = P \times \left(1 + \frac{r}{n}\right)^{n \times t}$$A=P×(1+nr​)n×t

Where:

• A = Final Amount
• P = Principal Amount
• r = Annual Interest Rate
• n = Number of times interest is compounded per year
• t = Time in years

This formula shows how your investment grows faster due to compounding.

How Does Compound Interest Work?

Compound interest works on the concept of “interest on interest.”

Here’s how it works:

1. You invest an initial amount
2. Interest is added after a fixed period
3. The next interest is calculated on the new total
4. This process continues over time

As time increases, the growth becomes faster because your returns also start generating returns.
