The simple interest formula calculates interest on SBI loans based on the principal amount, annual interest rate, and time period. It provides a straightforward method to determine how much interest will be charged on a loan.

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 interest by multiplying the principal amount by the interest rate and the time period.

3. Importance of Interest Calculation

Details: Accurate interest calculation is crucial for understanding loan costs, financial planning, and comparing different loan options from SBI and other lenders.
