Buying a car is an exciting experience, but it often comes with a big financial decision: how will you pay for it? For many, auto loans are the go-to option. However, understanding how much you’ll owe monthly, the total loan cost, and the interest you’ll pay can feel overwhelming. That’s where our CarMax Auto Loan Calculator comes in.

How to Use the CarMax Auto Loan Calculator
Using the calculator is quick and easy. Just follow these steps:
- Enter the Car Price
Input the total price of the car you are considering. For example, if the car costs $25,000, enter that number in the “Car Price” field. - Add Your Down Payment
Enter the amount you plan to pay upfront. A larger down payment reduces the loan amount, interest paid, and monthly payments. - Input the Interest Rate (%)
Enter the annual percentage rate (APR) offered by your lender. Even a small difference in interest rate can greatly affect total costs. - Set the Loan Term (Months)
Choose the length of your loan in months (e.g., 36, 48, 60, or 72 months). Longer terms usually mean lower monthly payments but higher overall interest. - Click "Calculate"
Hit the Calculate button, and the tool will instantly show you:- Loan Amount
- Monthly Payment
- Total Payment

Practical Example
Let’s walk through an example to see how it works in practice.
- Car Price: $30,000
- Down Payment: $5,000
- Interest Rate: 6% APR
- Loan Term: 60 months (5 years)
Calculation Results:
- Loan Amount: $25,000
- Monthly Payment: About $483.32
- Total Payment: $28,999.20
- Total Interest: $3,999.20
This means you’d pay just under $500 per month for 5 years and end up paying nearly $4,000 in interest over the life of the loan.
With this insight, you can adjust your down payment, compare interest rates, or change the term to find a plan that fits your budget.
Why Use a Car Loan Calculator?
A car loan is a long-term financial commitment, and small details make a big difference. Using our CarMax Auto Loan Calculator helps you:
- Understand affordability before committing to a car.

Tips for Managing Your Auto Loan
Here are a few strategies to keep your loan manageable and cost-effective:
- Make a larger down payment – reduces loan amount and interest.
- Shop for the best APR – even a 1–2% difference can save you thousands.
- Keep the loan term reasonable – avoid overly long loans that rack up interest.
- Pay extra when possible – additional payments go toward principal, reducing interest.
- Check your credit score – better credit often means better interest rates.
