2. How Does the Calculator Work?

The calculator uses the simple interest formula:

Where:

• \( I \) — Interest amount (currency)
• \( P \) — Principal amount (currency)
• \( r \) — Annual interest rate (decimal)
• \( t \) — Time period (years)

Explanation: The formula calculates the interest by multiplying the principal amount by the annual interest rate and the time period in years.

3. Importance of Interest Calculation
