1. What is the Total Interest Formula?

The Total Interest formula calculates the total interest paid over a loan tenure. 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)
• \( N \) — Number of monthly payments
• \( P \) — Principal amount (currency)
• \( I \) — Total interest paid (currency)

Explanation: This formula calculates the difference between the total amount paid over the loan term and the original principal borrowed.

3. Importance of Total Interest Calculation

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

4. Using the Calculator

Tips: Enter the EMI amount, number of monthly payments, and principal amount. All values must be positive numbers.

Q3: How can I reduce my total interest payment?
