1. What is Simple Interest Calculation?

Simple interest is a quick method of calculating the interest charge on a loan or savings. It is determined by multiplying the principal amount by the interest rate and the time period.

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: This formula calculates the interest earned or paid based on the initial principal without considering compounding effects.

3. Importance of Interest Calculation

Details: Understanding interest calculations is essential for financial planning, comparing investment options, and managing debt effectively.

4. Using the Calculator

Tips: Enter the principal amount in currency, annual interest rate as a decimal (e.g., 0.05 for 5%), and time period in years. All values must be positive numbers.

Q2: How do I convert percentage to decimal?
A: Divide the percentage by 100. For example, 5% becomes 0.05 as a decimal.

Q3: Can this calculator handle monthly calculations?
