How to Use the CarMax Auto Loan Calculator: Step-by-Step Guide
Our calculator is intuitive and takes less than a minute to use. Here’s a step-by-step guide:
- Enter Car Price ($):
Input the total price of the vehicle you intend to buy. - Enter Down Payment ($):
Enter the amount you plan to pay upfront. A larger down payment reduces your loan amount and monthly payment. - Enter Trade-In Value ($):

Choose the number of months you want to finance the vehicle—common terms include 36, 48, 60, 72, and 84 months. - Enter Interest Rate (%):
Input the interest rate offered by your lender. You can get this from your pre-approval, dealership offer, or credit union. - Enter Sales Tax Rate (%):
The default is 6%, but you can adjust it based on your state or local tax rate. - Choose Warranty Option:
Select whether you want to include an extended warranty. If “Yes,” input the estimated cost of the warranty. - Click “Calculate”:
Hit the Calculate button, and the tool will display your Loan Amount, Monthly Payment, Total Interest, Total Cost, Sales Tax, and Payoff Date.

Frequently Asked Questions (FAQs)
1. What is a good interest rate for a car loan?
A good rate varies by credit score. For excellent credit, rates below 5% are common. For fair or poor credit, rates can exceed 10–15%.
2. How is sales tax calculated on a car loan?
Sales tax is typically calculated on the purchase price before down payment and added to the total loan amount.
3. Do I need a loan if my trade-in covers the cost?
No. If your trade-in plus down payment covers the full cost (including taxes and fees), you don’t need a loan.
4. Can I use this calculator for a used car?
Yes. The calculator works for both new and used vehicles.
5. Does the calculator include insurance costs?
No, insurance is not included. Add it separately to get a full picture of monthly expenses.
6. What if I want to make extra payments?
This calculator assumes regular fixed payments. For early payoff scenarios, consider a more advanced amortization calculator.
7. Is it better to finance through CarMax or a bank?
It depends. Banks may offer better rates, while CarMax financing may offer convenience. Always compare offers.
8. How accurate is the monthly payment shown?
It’s an estimate based on your inputs. Your actual payment may vary depending on lender fees and credit terms.
9. Can I include registration and title fees?
This calculator does not include those by default. Add them manually to the car price for a more accurate total.
10. Is extended warranty worth it?
It depends on the vehicle’s reliability and how long you plan to keep it. Including it in your loan spreads out the cost.
11. Can I use this calculator for a lease?
No, leases have different structures. Use a lease-specific calculator instead.
12. How do I find out my credit score?
You can check through your bank, credit card provider, or free services like Credit Karma.
13. What happens if I miss a car payment?
Missing a payment can damage your credit and may lead to late fees or repossession. Always contact your lender early.
14. Can I negotiate my interest rate?
Yes. You can negotiate with dealerships and lenders, especially with a pre-approval offer in hand.
15. Does warranty affect my loan approval?
No, but adding warranty cost increases your loan amount, which may impact approval if you’re near your borrowing limit.
16. Should I choose a longer or shorter loan term?
Shorter terms cost less overall but have higher monthly payments. Choose what fits your budget and goals.
17. Can I use the calculator on my phone?
Yes, it’s mobile-friendly and can be used on any device with a browser.
18. What’s the average car loan term in the US?
