1. What is the CD Interest Calculator?

The CD Interest Calculator calculates the maturity amount of a Certificate of Deposit (CD) using daily compounding interest. It helps investors understand how much their investment will grow over a specific period.

2. How Does the Calculator Work?

The calculator uses the daily compounding formula:

Where:

• \( A \) — Maturity amount ($)
• \( P \) — Principal investment ($)
• \( R \) — Annual interest rate (decimal)
• \( D \) — Number of days

Explanation: The formula calculates interest compounded daily, providing accurate results for CD investments of any duration.

3. Importance of CD Interest Calculation

Details: Accurate CD interest calculation helps investors compare different investment options, plan for financial goals, and maximize returns on their savings.

4. Using the Calculator

Tips: Enter principal amount in dollars, annual interest rate as a decimal (e.g., 0.05 for 5%), and number of days. All values must be positive.
