1. What is the Total Interest Formula?

The Total Interest formula calculates the total interest paid over the life of a mortgage loan. It provides a clear picture of the additional cost beyond the principal amount borrowed.

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 over the loan term and the original principal borrowed.

3. Importance of Total Interest Calculation

Details: Understanding total interest helps borrowers evaluate the true cost of a mortgage, compare different loan options, and make informed financial decisions.

4. Using the Calculator

Tips: Enter EMI in currency units, number of months, and principal amount. All values must be valid positive numbers.
