1. What is the Car Loan Interest Formula?

The car loan interest formula calculates the total interest paid over the entire loan tenure. It provides a clear picture of the additional cost of borrowing beyond the principal amount.

2. How Does the Calculator Work?

The calculator uses the interest formula:

Where:

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

Explanation: The formula calculates the total amount paid over the loan period and subtracts the principal to determine the interest cost.

3. Importance of Interest Calculation

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

4. Using the Calculator

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