Auto Loan Calculator
Use this free Auto Loan Calculator to quickly calculate your monthly car payments and total interest. Simple, accurate, and easy to use online.
Purchasing a vehicle is often the second largest financial decision many people make, right after buying a home. The Auto Loan Calculator is a powerful tool designed to help you navigate this process with confidence. It allows you to estimate your monthly car payments based on the vehicle's price, your down payment, the interest rate (APR), and the loan term.
Understanding the true cost of an auto loan goes beyond just fitting a monthly payment into your budget. It involves understanding how interest rates, loan terms, and down payments interact to determine the total amount you will pay over the life of the loan. Whether you are buying a brand-new sedan, a used truck, or looking to refinance your current vehicle, this calculator provides the transparency you need to negotiate better deals and avoid overpaying.

What This Calculator Does
Our Free Auto Loan Calculator is designed to take the guesswork out of buying a car. It provides a precise estimate of your monthly car payments based on the vehicle's price, your down payment, trade-in value, interest rate, and the loan term.
Unlike simple estimators, this tool calculates the Total Interest you will pay over the life of the loan, helping you understand the true cost of borrowing money. It empowers you to walk into a dealership with confidence, knowing exactly what you can afford.
Why Use This Auto Loan Calculator?
- See the True CostA low monthly payment on a 7-year loan might sound good, but it often means paying thousands more in interest. This tool reveals the total cost so you can decide if it's worth it.
- Negotiate Better DealsWhen you know exactly how interest rates and down payments affect your bottom line, you can spot bad deals and negotiate effectively with lenders.
- Plan Your BudgetEnsure your new car fits comfortably within your monthly budget, leaving room for insurance, fuel, and maintenance.
How to Use This Calculator (Step-by-Step)
The total negotiated price of the car (after rebates but before tax/fees in many cases). Don't just focus on the sticker price.
Enter any cash you are putting down plus the value of your old car. These reduce the loan amount significantly.
Enter your expected APR. This naturally varies by credit score and whether the car is new or used.
Choose how many months you will take to repay the loan. Common terms are 36, 48, 60, or 72 months.
Understanding the Results
Monthly Payment
The amount you must pay the lender every month to pay off the loan by the end of the term.
Total Interest
The "price" of the loan. This is money paid purely to the bank for the privilege of borrowing.
Total Cost
The actual amount you paid for the car (Price + Interest). This is often much higher than the sticker price.
Common Mistakes When Buying a Car
- Focusing Only on Monthly Payment: Dealers can lower your monthly payment by extending the loan term (e.g., to 84 months), but this drastically increases your total interest.
- Ignoring Total Cost: Always look at the "Total Cost" figure. A "cheap" monthly payment might cost you $5,000 extra in the long run.
- Forgetting Extra Costs: Remember to budget for insurance, fuel, registration, and maintenance. The car note is only part of the expense.
Frequently Asked Questions
What is a good auto loan interest rate?
Interest rates fluctuate with the economy and your credit score. Excellent credit (750+) might secure 3-5%, while subprime scores might see 10-15%+.
Does the loan term affect my interest rate?
Often, yes. Lenders usually offer lower interest rates for shorter terms (e.g., 36 or 48 months) because the risk of default is lower.
What is 'Gap Insurance'?
Gap insurance covers the difference between what you owe on the car and what it's worth if it gets totaled. It's useful if you have a small down payment.
Can I pay off my car loan early?
Usually, yes. Paying extra towards the principal reduces the total interest you pay and helps you finish the loan sooner. Always check for 'prepayment penalties' first.
Leasing vs Buying: Which is better?
Leasing offers lower monthly payments and a new car every few years but you build no equity. Buying costs more monthly but you own the asset once the loan is paid off.
How much should I put down?
Experts recommend at least 20% for a new car and 10% for a used car. This helps avoid being 'underwater' (owing more than the car is worth).
When to Use This Calculator
You should use the Auto Loan Calculator whenever you are in the market for a vehicle or reviewing your current car loan. Specifically, it is useful in the following scenarios:
- Budgeting for a Car: Before you step onto a dealership lot, use this tool to determine how much car you can actually afford based on your monthly cash flow.
- Comparing Loan Offers: If you have pre-approval offers from a bank, a credit union, and the dealership financing office, input the different rates and terms to see which one saves you the most money.
- Refinancing Analysis: If interest rates have dropped or your credit score has improved since you bought your car, calculate if refinancing could lower your monthly payments or reduce total interest costs.
Example Scenario
Let's consider a realistic scenario to see how the numbers work. Imagine you want to buy a car priced at $30,000.
- Vehicle Price: $30,000
- Down Payment: $5,000 (Trade-in + Cash)
- Loan Amount: $25,000
- Interest Rate: 5.0% APR
- Loan Term: 60 months (5 years)
Using the standard amortization formula, the calculator would determine that your monthly payment is approximately $471.78. Over the course of 5 years, you would pay a total of roughly $3,306 in interest, making the total cost of the loan $28,306 (plus your initial $5,000 down payment).
