1. What is the SBI Personal Loan Interest Formula?

The SBI Personal Loan Interest Formula calculates the interest amount for a loan using the simple interest formula I = P × r × t, where I is the interest amount, P is the principal amount, r is the annual interest rate in decimal form, and t is the time period in years.

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 simple interest amount by multiplying the principal amount by the annual interest rate and the time period in years.

3. Importance of Interest Calculation

Details: Accurate interest calculation is crucial for understanding the total cost of a loan, budgeting for repayments, and making informed financial decisions when taking personal loans.

4. Using the Calculator

Tips: Enter the principal amount in currency, annual interest rate in decimal form (e.g., 0.1 for 10%), and time period in years. All values must be valid (principal > 0, rate ≥ 0, time > 0).
