A compound interest calculator is a tool used to calculate the future value of an investment or loan that accrues interest over time, with interest being added to the principal balance periodically. Here's a breakdown of how it works:

1. Principal Amount: The initial amount of money invested or borrowed.

2. Interest Rate: The annual rate at which interest is applied to the principal amount.

3. Compounding Period: The frequency at which interest is compounded, such as annually, semi-annually, quarterly, or monthly.

4. Time: The duration for which the investment or loan will be held, usually expressed in years.

5. Formula: The calculator applies the compound interest formula to calculate the future value of the investment or loan:

**Future Value = Principal Amount × (1 + (Interest Rate / Compounding Period))^(Compounding Period × Time)**

6. Input: Users input the principal amount, interest rate, compounding period, and time into the calculator.

7. Calculation: The calculator computes the future value based on the provided inputs.

8. Output: The calculated future value is displayed to the user, showing the total amount that will be accrued or repaid over the specified time period.
Compound interest calculators are valuable tools for individuals and businesses to estimate the growth of investments or the total repayment amount of loans, helping them make informed financial decisions.
