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:

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

Explanation: The formula calculates the fixed payment that pays off the loan with interest over the specified term. The payment remains constant, but the proportion going toward principal vs. interest changes over time.

3. Understanding Loan Payments

Details: Each payment consists of both principal (the original loan amount) and interest (the cost of borrowing). Early payments are mostly interest, while later payments are mostly principal.

4. Using the Calculator

Tips: Enter the total loan amount, annual interest rate (APR), and loan term in months. The calculator will show your estimated monthly payment.

5. Frequently Asked Questions (FAQ)

Q1: What's included in a typical car payment?
A: This calculator shows principal and interest only. Your actual payment may include taxes, fees, and insurance if financed.

Q2: How does loan term affect payments?
A: Longer terms reduce monthly payments but increase total interest paid. Shorter terms have higher payments but lower total cost.

Q3: What is amortization?
A: The process of gradually paying off a loan through regular payments that cover both principal and interest.

Q4: How can I reduce my car payments?
A: Consider a larger down payment, shorter loan term, or negotiating a lower interest rate.

Q5: What's the difference between APR and interest rate?
A: APR includes both the interest rate and any additional loan fees, giving a more complete picture of borrowing costs.
