1. What is the Auto Loan Payment Formula?

The auto loan payment formula calculates the fixed monthly payment required to repay a 24-month auto loan, including interest. It accounts for the principal amount, monthly interest rate, and loan term.

2. How Does the Calculator Work?

The calculator uses the auto loan payment formula:

Where:

• \( PMT \) — Monthly payment amount
• \( P \) — Principal loan amount
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• 24 — Number of monthly payments (2 years)

Explanation: The formula calculates the fixed payment that pays off the loan plus interest over exactly 24 months.

3. Importance of Loan Payment Calculation

Details: Knowing your exact monthly payment helps with budgeting and comparing loan offers. It ensures you can afford the vehicle before committing to the purchase.

4. Using the Calculator

Tips: Enter the total loan amount in dollars and the monthly interest rate as a decimal (e.g., 0.005 for 0.5% monthly rate). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q4: Why does my actual payment differ slightly?
