- The formula to calculate compound interest is A = P(1 + r/n)^nt.
- Where A is the future value.
- P is the principal, r is the annual interest rate, n is the number of times the interest is compounded per year.
- And t is the number of years the money is invested.

### What is compound Interest?

Compound interest is a type of interest that is earned on top of the initial principal amount that is invested. This type of interest is calculated on a periodic basis and can be reinvested to earn even more compound interest.

**What Is the Difference Between Simple and Compound Interest?**

The difference between simple and compound interest is that simple interest is calculated only on the initial principal, while compound interest is calculated on the initial principal as well as on any accumulated interest. This means that with compound interest, you earn interest on your interest, which can result in a much larger total return over time.

**How do I calculate compound interest in stocks for future years?**

To calculate compound interest in stocks for future years, you need to know the annual rate of return, the number of years, and the initial stock value.

The annual rate of return is the percentage increase in the stock’s value each year. To find this, divide the increase in the stock’s value by the number of years.

The number of years is how many years you want to calculate the compound interest for.

**How does compound interest work when investing in stocks?**
