1. What is the Auto Loan Payment Formula?

The auto 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:

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

Explanation: The formula accounts for compound interest over the life of the loan, calculating a fixed payment that covers both principal and interest.

3. Importance of Loan Calculation

Details: Understanding your monthly payment helps with budgeting and ensures you can afford the vehicle. Texas-specific factors like sales tax (6.25%) and registration fees should also be considered.

4. Using the Calculator

Tips: Enter the total loan amount (after down payment), annual interest rate (APR), and loan term in months. Texas dealers typically offer terms from 36 to 72 months.
