1. What is Quarterly Compounding?

Quarterly compounding is a method where interest is calculated and added to the principal four times per year. This results in higher returns compared to annual compounding due to the more frequent application of interest.

2. How Does the Calculator Work?

The calculator uses the quarterly compounding formula:

\[ A = P \times (1 + \frac{R}{4})^{4 \times T} \]

Where:

$ A $ — Maturity amount ($)
$ P $ — Principal amount ($)
$ R $ — Annual interest rate (as decimal)
$ T $ — Time period (years)

Explanation: The formula calculates the future value of an investment where interest is compounded quarterly, taking into account the principal, annual interest rate, and time period.

3. Importance of Quarterly Compounding

Details: Understanding quarterly compounding is essential for investors to accurately calculate returns on certificates of deposit and other fixed-income investments that compound interest quarterly.

4. Using the Calculator

Tips: Enter the principal amount in dollars, annual interest rate as a percentage, and time period in years. All values must be positive numbers.
