1. What is the Car Loan Payment Formula?

The car loan payment formula calculates the fixed monthly payment required to repay a car loan over a specified term. It accounts for the principal amount, interest rate, and loan duration.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

• \( P \) — Principal loan amount (USD)
• \( r \) — Monthly interest rate (annual rate ÷ 12, in decimal)
• \( n \) — Number of monthly payments (loan term in months)
• \( PMT \) — Monthly payment amount (USD)

Explanation: The formula calculates the fixed payment that covers both principal and interest each month, with more going toward interest early in the loan.

3. Importance of Loan Calculation

Details: Understanding your monthly payment helps with budgeting and comparing loan offers. It shows the true cost of financing a vehicle.

4. Using the Calculator

Tips: Enter the total loan amount (after down payment), annual interest rate (APR), and loan term in months. All values must be positive numbers.
