The calculator uses the CD interest formula:

Where:

• \( I \) — Interest earned (currency units)
• \( A \) — Maturity amount (currency units)
• \( P \) — Principal amount (currency units)

Explanation: The formula calculates the difference between the final maturity value and the initial investment to determine the total interest earned.
