1. What is the Mortgage Interest Formula?

The Mortgage Interest Formula calculates the total interest paid over the entire mortgage tenure. It provides a clear picture of the additional cost beyond the principal amount borrowed.

2. How Does the Calculator Work?

The calculator uses the mortgage interest formula:

Where:

• \( EMI \) — Equated Monthly Installment (monthly payment)
• \( N \) — Total number of monthly payments
• \( P \) — Principal loan amount
• \( I \) — Total interest paid over the loan term

Explanation: The formula calculates the difference between the total amount paid (EMI × N) and the original principal to determine the interest cost.

3. Importance of Interest Calculation

Details: Understanding total interest cost helps borrowers make informed decisions about loan terms, compare different mortgage options, and plan their long-term financial strategy.

4. Using the Calculator

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