1. What is CD Interest Calculation?

CD (Certificate of Deposit) interest calculation determines the amount of interest earned on a fixed deposit investment over a specified period. It helps investors understand their potential returns before committing funds.

2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Interest earned (currency units)
• \( P \) — Principal amount invested (currency units)
• \( R \) — Annual interest rate (%)
• \( T \) — Time period (years)

Explanation: This formula calculates simple interest, which means interest is earned only on the principal amount and not on previously earned interest.

Details: Calculating CD interest helps investors compare different investment options, plan for future financial goals, and make informed decisions about where to place their savings for optimal returns.

4. Using the Calculator

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