1. What is Total Interest Calculation?

Total interest calculation determines the total amount of interest paid over the life of a bank loan. It helps borrowers understand the true cost of borrowing beyond just the principal amount.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( EMI \) — Equated Monthly Installment (currency units)
• \( m \) — Number of months (unitless)
• \( P \) — Principal amount (currency units)

Explanation: The formula calculates the difference between the total amount paid (EMI × months) and the original principal, which represents the interest cost.

3. Importance of Total Interest Calculation

Details: Understanding total interest helps borrowers make informed decisions about loan products, compare different loan options, and plan their finances effectively.

4. Using the Calculator
