1. What is the Auto Loan Payment Formula?

The auto loan payment formula calculates the fixed monthly payment required to repay a loan over a specified period at a given interest rate. This is the standard formula used by Navy Federal Credit Union and most lenders for amortizing loans.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

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

Explanation: The formula accounts for both principal and interest payments, with more interest paid early in the loan term and more principal paid later.

3. Importance of Accurate Payment Calculation

Details: Knowing your exact monthly payment helps with budgeting and ensures you can comfortably afford the vehicle. It also allows you to compare different loan options.

4. Using the Calculator

Tips: Enter the total loan amount (after down payment), the annual interest rate (as a decimal), and the loan term in months. Navy Federal's current auto loan rates can be found on their website.
