1. What is Total Interest Calculation?

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

2. How Does the Calculator Work?

The calculator uses the total interest 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 terms, compare different loan offers, and plan their finances effectively by knowing the true cost of credit.

4. Using the Calculator

Tips: Enter the monthly EMI payment, the total number of months in the loan term, and the principal amount. All values must be positive numbers.
