Auto Loan Payment Calculator
By Jennifer Calonia | Updated July 2, 2025
If you’re contemplating car financing, you likely want to compare your options. Whether you’re in the hot seat at a dealership’s financing office or doing research at home, you need to quickly and easily find the best car loan for an upcoming vehicle purchase.
This auto loan payment calculator gives you a clear view of the monthly payment you can expect and total interest you’ll pay, just by entering a few loan details.
Key Points
• To estimate auto loan payments, input the total loan amount, term length, and interest rate into the calculator.
• Adjust the variables to match your budget and available loans.
• Evaluate different scenarios to find the best loan offer.
• Review the breakdown of principal and interest to understand payment structure.
• Calculate the estimated total interest to be paid over the loan term.
Calculator Definitions
When using the auto loan payment calculator, you’ll want to understand these terms:
• Down payment: An out-of-pocket portion of the vehicle purchase price that you pay upfront. This figure reduces the loan amount you’ll borrow.
• Principal: The base loan amount that’s borrowed for the vehicle purchase.
• Interest rate: This is the cost of borrowing the loan. The interest rate is expressed as a percentage of the principal. (You might see it sometimes shown as an APR, or annual percentage rate, which includes the cost of interest plus fees.)
• Loan term: The length of time, expressed in months or years, that you’ll repay the loan.
• Monthly payment: The amount that you’re required to pay each month as a loan installment. It includes a portion of the principal and interest charges.
How to Use the Auto Loan Payment Calculator
You can get started with the auto loan payment calculator in three simple steps.
1. Enter the Loan Amount
Use the slider to enter the loan amount you intend on borrowing. You can also type the amount into the field provided. The amount can be as low as $5,000 up to $100,000.
2. Enter the Loan Term
Enter the loan term, or repayment duration, in years using the slider or by typing it into the text field. Available loan terms are usually between one and 10 years.
Some loan terms are expressed as months. If this is the case with your loan, divide its repayment term by 12 to get the number of term years. For example, a 72-month term, divided by 12, is a 6-year loan term.
3. Enter the Interest Rate
Input the interest rate for the loan into the “interest rate” text field.
As you make changes to each loan detail field, you’ll see the auto loan payment calculator dynamically update your estimated monthly payment information on the right. You’ll see insightful breakdowns, like your monthly payment amount, how much of that payment is applied to the loan principal vs. interest, and the total interest you’ll pay over the loan term.
As you may have noted, this is not an auto loan calculator with credit score. It will calculate payments and total interest based on an interest rate vs. a score.
Benefits of Using an Auto Loan Payment Calculator
Using an auto loan payment calculator empowers you to make informed decisions before financing your next vehicle. It helps you:
• Budget your monthly finances by offering concrete estimates.
• Compare auto loan financing offers.
• Visualize how loan terms impact your monthly payment.
• Understand how much of each payment goes toward the principal balance.
• See how much you’re paying in total interest charges.
How to Use the Auto Loan Payment Calculator to Compare Scenarios
A practical way to use the auto loan payment calculator is by adjusting each variable — loan amount, loan term and interest rate — to guide you toward your ideal loan offer.
Scenario 1. Say you check your budget and use a money tracker app and determine that you can spend $500 a month for a car payment. You are considering making a down payment of $10,000 toward a $40,000 car.
This means the loan amount you’d finance is $30,000. Assuming a five-year term at 6%, your estimated payment is $1,079.99. This estimated monthly payment is more than twice your budgeted amount, so this loan isn’t financially feasible.
Scenario 2. To get closer to your preferred monthly payment budget, you consider buying a more affordable car and extending your loan term. The next car you consider requires a loan amount of $20,000, and you choose a 7-year term at 6%. Now, your estimated monthly auto payment is $530.27 — much more in line with your desired budget.
By using the auto loan payment calculator in this way, you can find which particular vehicle and loan suits you best.

What Is a Credit Score?
A credit score is a three-digit number that summarizes your creditworthiness, based on your past and current borrowing and repayment habits. The Fair Isaac Corporation (FICO®) is a popular credit scoring model that’s used by lenders to assess how risky lending to you might be, however, the VantageScore is another commonly used model. One key similarity between the VantageScore vs. FICO is that both generally use a credit score range from 300-850.
These two models also consider similar factors in their credit score calculations:
• Payment history
• Credit utilization
• Credit length/age
• Credit mix
• New credit
Although each scoring model looks at similar data points, they differ in how impactful each factor is in their respective calculations. Your credit score updates regularly (often monthly), based on your most recently reported repayment and borrowing activity.
How to Build Credit
Understanding how to build credit and what affects your credit score can help you maintain a strong credit profile. Building your credit isn’t a precise science — instead, practicing responsible borrowing and payment behavior can positively impact your score overall. Paying at least the minimum payment due on your credit cards and loans each month can have a major influence on your FICO score; it makes up 35% of your score calculation.
Credit utilization, which is the amount of credit you use compared to your available credit, determines 30% of your FICO score. Keeping your credit utilization under 30% or ideally 10% of your available credit can help build your score. (A spending app might help you take control of this figure if yours is running high.)
Responsibly managing a mix of credit types and not opening multiple new credit accounts in a short period can also positively impact your score.
If you are working on building your score to qualify for more favorable terms, you might use a credit score auto loan calculator to gauge the impact of this activity.

Types of Credit
There are different types of credit that come together to form your credit file. The main credit types include:
• Revolving credit. A revolving account typically provides you with the ability to borrow against a credit line up to a predetermined credit limit. Common examples include credit cards, retail cards, gas station cards, and home equity lines of credit (HELOCs).
• Installment credit. Installment credit offers a fixed payout that is disbursed upfront as a lump sum. Then, you’ll make smaller installment payments over multiple months until the principal balance, plus interest and fees, are repaid. Auto loans, student loans, and home loans are examples of installment debt.
• Open credit. With open credit, the full payment is due each month or statement cycle. This type of credit account is typically seen through service providers, like for utilities or your cell phone.
Examples of Credit Score Ranges
Scoring models might have different score ratings and ranges. Below is an example of a basic FICO score range:
• Excellent: 800-850
• Very Good: 740-799
• Good: 670-739
• Fiar: 580-669
• Poor: 300-579
You may be curious about your starting credit score. It’s not typically 300, the lowest possible score. Rather, once you have several months of credit history, if it’s responsible, you might be in, say, the good range.
Credit Score Tips
Before you shop around for an auto loan, knowing where your credit stands and addressing any areas to positively impact your score can help you secure a more favorable financing offer.
• Credit score monitoring can help you track new credit inquiries, account openings, and flag issues, like fraudulent activity. This in turn can protect your score.
• Tapping into ways to check credit score without paying might make it easier to stay on top of your credit health.
• Learning lower credit card utilization can build your credit score in a meaningful way.

FAQ
What credit score do you need for a car loan?
There’s no gold-standard score that automatically qualifies you for a car loan. Generally, a minimum credit score of 670, which is considered good under FICO’s scoring model, can help qualify a person for a loan. However, the higher your score, the better your chances at getting approved for an auto loan.
What APR will I get with a 700 credit score for a car?
Borrowers with prime credit, which includes a 700 credit score, have an average new auto loan rate of 6.70% APR and 9.06% APR for a used car loan as of June 2025.
Can I get a $30K car with a 650 credit score?
A 650 FICO score is considered “fair” which is slightly lower than the average U.S. consumer. Lenders might be willing to finance a $30K car loan based on this score or might require a cosigner on the loan agreement.
How much does a credit score go down when applying for an auto loan?
Applying for an auto loan involves a hard inquiry into your credit history. This inquiry can temporarily lower your score by several (say, five) points.
Why did my credit score drop 100 points after paying off my car?
Identifying why your credit score might drop 100 points after paying off an auto loan is complex since your score is comprised of multiple factors. For example, the drop could be a result of the account now being closed, which shortens your credit history; changes in your credit mix; or other reasons.
What interest rate can I get with a 750 credit score for a car?
The average auto loan rate for consumers with prime credit (661-780) is 6.70% for a new car loan to 9.06% for a used car loan, according to June 2025 Experian® data.
