1. What is Quarterly Compounding?

Quarterly compounding is a method where interest is calculated and added to the principal amount four times per year. This results in earning interest on previously earned interest, which can significantly increase your returns over time compared to simple interest.

2. How Does the Calculator Work?

The calculator uses the quarterly compounding formula:

\[ A = P \times \left(1 + \frac{R}{100 \times 4}\right)^{4 \times T} \]

Where:

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

Explanation: The formula calculates how much your investment will grow when interest is compounded quarterly, taking into account the principal, annual interest rate, and time period.

3. Importance of CD Rate Calculation

Details: Calculating CD returns with quarterly compounding helps investors understand the true growth potential of their investments, compare different CD offerings, and make informed financial decisions about where to place their savings.

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. The calculator will show both the maturity amount and the interest earned.
