1. What is the Mortgage Interest Formula?

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

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

3. Importance of Interest Calculation

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

4. Using the Calculator

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