Compound Interest Calculator

A "Compound Interest Calculator" is a financial tool that helps users calculate the growth of an investment or loan over time when compound interest is applied. 

Compound interest is the interest calculated on the initial principal amount as well as on the accumulated interest from previous periods.

Here's how a Compound Interest Calculator typically works:

1. Input Parameters: Users provide the initial principal amount, the interest rate per period, the number of compounding periods per year, and the total number of years the investment or loan will be held.

2. Calculate Interest: The calculator uses the compound interest formula to determine the future value of the investment or loan based on the provided parameters.

3. Display Results: The tool shows the total amount accumulated, the interest earned, and the growth of the investment or loan over the specified period.

This calculator is valuable for individuals, investors, and financial professionals who want to understand how their money will grow or how much interest will accrue over time with compound interest. 

It helps users make informed decisions about investments, savings, loans, and other financial matters by providing them with a clear picture of the potential growth or cost associated with compound interest.
