Compound Interest Calculator

This compound interest calculator helps you visualize how your savings or investments can grow over time with regular monthly contributions and compounding interest.

How It Works

Compound interest means you earn interest not only on your initial investment (principal) but also on the interest that accumulates over time. The calculator takes into account:

• Initial Amount ($): Your starting investment.

• Monthly Investment ($): The amount you add every month.

• Annual Interest Rate (%): The expected yearly return, compounded monthly.

• Years: The total investment period in years.

Every month, the calculator applies interest to the total amount and adds your monthly contribution. This builds up exponentially, showing the power of compounding.
