What Bankrate's auto loan calculator does
Bankrate's auto loan calculator takes four pieces of information — the car's price, how much you're putting down, the interest rate, and the loan term in months — and shows you the monthly payment, total interest paid, and total cost of the loan. It does not connect to lenders, does not check your credit, and does not lock in any rate. It is a math tool that lets you see how different numbers change your payment before you talk to a bank or credit union.
The calculator lives on Bankrate's website under their auto loans section. You enter the vehicle price (the actual amount you're financing, not the sticker price), your down payment in dollars, the interest rate you expect to get, and how many months you want to borrow for. The tool then displays your monthly payment, the total amount of interest you'll pay over the life of the loan, and what you'll pay altogether.
This matters because the difference between a 48-month and 72-month loan, or between a 5% and 7% rate, changes your monthly payment by hundreds of dollars. Seeing those numbers before you shop helps you know what payment range is realistic for your budget.
Key Takeaways
- Bankrate's calculator shows monthly payment, total interest, and total loan cost based on price, down payment, rate, and term — but does not lock in any rate or connect to actual lenders.
- The interest rate you enter is a guess on your part; your actual rate depends on your credit score, income, and which lender you choose.
- Changing the loan term from 60 to 72 months lowers your monthly payment but raises the total interest you pay significantly.
- The calculator is most useful for comparing scenarios — seeing how a larger down payment or a better rate would change your payment — rather than as a final quote.
How to use the calculator step by step
Start with the vehicle price. This should be the actual amount you plan to finance, not the manufacturer's suggested retail price. If you're buying a $28,000 car and the dealer is offering it for $26,500, use $26,500. If you're financing a used car you found for $12,000, use that number.
Next, enter your down payment in dollars. If you have $5,000 saved, enter 5000. The calculator will subtract this from the vehicle price to show you the loan amount. A larger down payment lowers the amount you borrow, which lowers your monthly payment and the total interest you pay.
Then enter the interest rate you expect. This is where most people guess. If you have good credit, you might expect a rate between 4% and 6%. If your credit is fair, you might see 6% to 8%. If your credit is poor, you might see 8% to 12% or higher. You can run the calculator multiple times with different rates to see a range of outcomes.
Finally, choose your loan term in months. Common terms are 36, 48, 60, and 72 months. A shorter term means a higher monthly payment but less total interest. A longer term spreads the cost across more months, lowering the payment but raising the total interest you'll pay.
What the calculator does not tell you
The calculator shows you the payment on the loan itself, but not the full cost of owning the car. It does not include insurance, registration, maintenance, fuel, or repairs. A $300 monthly payment might fit your budget, but $300 plus $150 for insurance plus $100 for gas might not. Budget for the whole picture, not just the loan payment.
The calculator also does not account for taxes or dealer fees. Most states add sales tax to the vehicle price, and dealers charge documentation fees, registration fees, or other costs. These can add $1,000 to $3,000 or more to the total amount you finance, depending on your state and the dealer. Ask the dealer for an itemized quote that includes all fees before you use the calculator.
The interest rate you enter is your own estimate, not a rate you've been offered. Your actual rate depends on your credit score, your income, your debt-to-income ratio, the lender you choose, and the term you select. A bank might offer you 5.5%, while a credit union offers 5.2%, and a subprime lender offers 9.8%. The calculator cannot predict which lender will approve you or what rate they'll give you.
How loan term affects your payment and total cost
Loan term is the biggest lever you have to change your monthly payment. A $25,000 loan at 6% interest costs $483 per month over 60 months, but only $347 per month over 84 months. That's $136 less per month — but you'll pay $2,408 more in total interest over the life of the loan.
The longer you borrow, the more interest you pay, because interest accrues on the remaining balance every month. A 72-month loan gives the lender more time to collect interest, so the total cost is higher even though your monthly payment is lower. If you can afford a shorter term, you'll pay less overall. If you need the lower payment to fit your budget, a longer term is the trade-off.
Most lenders offer terms between 36 and 84 months. Some offer 96 months or longer, but these are less common and usually carry higher interest rates. Avoid stretching the term just to lower the payment; you'll end up paying thousands more in interest and may owe more than the car is worth if you need to sell or trade it in early.
Why your actual rate will differ from what you enter
The interest rate you type into the calculator is a starting point, not a promise. Your actual rate depends on several factors that the calculator cannot see: your credit score, your income, your existing debts, your employment history, and the size of your down payment.
Credit score is the biggest factor. Someone with a 750 credit score might get a 4.5% rate, while someone with a 650 score might get 7.5% for the same car and term. The difference is $50 to $100 per month on a $25,000 loan. If you don't know your credit score, you can check it free through AnnualCreditReport.com or through your bank's website.
The lender you choose also matters. Banks, credit unions, and online lenders set their own rates. A credit union might offer 5.2%, a bank might offer 5.8%, and an online lender might offer 6.1% — all for the same borrower. It's worth getting quotes from at least three lenders before you decide. Bankrate itself publishes average rates by credit score and lender type, which can help you set a realistic expectation.
Using the calculator to compare scenarios
The real power of the calculator is comparison. Run it once with a $5,000 down payment and a 60-month term. Then run it again with a $7,000 down payment and the same term. The difference shows you exactly how much that extra $2,000 saves you in monthly payment and total interest.
You can also compare terms. Run the calculator for 60 months, then 72 months, then 84 months, all with the same down payment and rate. This shows you the trade-off between a lower monthly payment and higher total interest as you stretch the loan longer.
Or compare rates. If you're unsure whether you'll get 5.5% or 6.5%, run the calculator both ways. Seeing the difference in dollars — not just percentages — helps you decide whether it's worth shopping around with multiple lenders or whether the difference is small enough to ignore.
Where to find Bankrate's calculator and similar tools
Bankrate's auto loan calculator is free and does not require you to enter your name, email, or any personal information. Go to Bankrate.com, navigate to their auto loans section, and look for the calculator tool. It's usually near the top of the page or in a sidebar.
Other sites offer similar calculators. NerdWallet, Edmunds, and Kelley Blue Book all have auto loan calculators that work the same way: you enter price, down payment, rate, and term, and they show you the payment. None of them connect to lenders or affect your credit. They're all free to use and useful for comparison.
After you've used the calculator to understand the math, you can move to getting actual quotes. Bankrate itself publishes current average rates by credit score and lender type, which gives you a realistic range to expect. Then contact banks, credit unions, and online lenders directly to see what rate they'll offer you based on your actual credit and income.
Frequently Asked Questions
Does using Bankrate's calculator hurt my credit score?
No. The calculator does not check your credit, does not submit any information to credit bureaus, and does not affect your score. It's just math. Your credit score only changes when a lender pulls your credit report, which happens when you formally request a loan.
What interest rate should I enter if I don't know what I'll get?
Start with the national average for your credit score range. Bankrate publishes these averages by credit tier. If you have good credit (700+), try 5% to 6%. If you have fair credit (650–700), try 6% to 8%. Then run the calculator multiple times with different rates to see a range of outcomes.
Can I use the calculator to lock in a rate?
No. The calculator shows you what a payment would be at a given rate, but it does not lock in that rate with any lender. You'll need to contact lenders directly and ask for a rate quote. Some lenders offer rate locks for 30 to 60 days once you've formally applied.
Should I choose the longest loan term to get the lowest payment?
Not automatically. A longer term lowers your monthly payment but raises the total interest you pay significantly. If you can afford a shorter term, you'll save thousands in interest. Only stretch the term if the shorter payment doesn't fit your budget.
Does the calculator include taxes and dealer fees?
No. The calculator only shows the loan payment on the vehicle price you enter. You'll need to add sales tax (which varies by state), documentation fees, registration, and any other dealer charges separately. Ask the dealer for a full itemized quote before you finalize your numbers.
