How do auto loans work?

Brief overview

When you decide to get a car - but don't have money to cover the full purchase price upfront - an auto loan gives you the flexibility to borrow money you need and pay it back over time. That way, you can start driving now and make monthly payments that fit your budget.

When you take out an auto loan, you agree to pay back the loan amount—plus interest—through monthly payments over a set period, called the loan term. Most auto loans range from 36 to 72 months. It’s a secured loan because the car itself is the collateral, meaning if you can't make the payments, the lender can take the car back.

Your monthly payment is made up of two parts: the principal, which is the amount you borrowed, and the interest, which is the cost of borrowing that money. A down payment - money you pay upfront - can reduce the total amount you need to borrow and lower your monthly payments.

Getting started

First, figure out how much money you’ll need to borrow, which can include the car's price, taxes, fees, and any extras you want to finance. In terms of financing options, you can shop around for the best loan terms and consider lenders like banks, credit unions, online lenders, or even the dealership.

Once you choose a lender, you’ll apply for the loan. You’ll usually need to share information like your income, job history, and credit score. Your credit score plays a big role in your loan. It not only impacts your ability to get approved for a loan but also what interest rate you’ll get. Generally, the better your credit, the lower interest rate you could qualify for, thus saving you money in the long run.

Post-loan considerations

Some auto loans allow for prepayments without penalties, which can help you save on interest over time. Additionally, refinancing your auto loan may be an option if you find better terms later on.

How to use the auto loan payment calculator

Using an auto loan calculator can help you estimate your monthly car payment before you commit to a loan. It helps you understand how different loan terms, interest rates, and down payments affect your budget. Be sure to double check your inputs to ensure they match the anticipated terms and rates of your loan. Even small errors can significantly affect the payment calculator’s output.

Steps to calculate your payment

Here’s how to get your estimate with the calculator at the top of the page:

1. Price of vehicle: Input the total amount you plan to borrow, including any extra features or packages you might want. For example, if you are looking to take out a loan for $30,000, enter “30000”. This is the amount before any down payment or trade-in value is applied.
2. Interest rate: Enter the annual interest rate for the auto loan into the box. For example, if the lender is going to charge you 5.5%, then enter “5.5” in the field.
3. Loan term: Choose how long you’d like to take to pay off the loan. For example, if you plan to repay the loan over 3 years, enter "3" and select “years,” or input “36” and select “months.”
4. Start date: Click the calendar icon to input the month and year when the loan begins.
5. Down payment: Enter the amount you plan to pay up front, if any. This reduces the total amount borrowed and can lower your monthly payment.
6. Trade-in: If you're trading in a vehicle, enter its estimated value here. This amount, along with your down payment, will be subtracted from the vehicle price to determine your loan amount and monthly payments.
7. Amount owed on trade-in: If you still owe money on your trade-in vehicle, enter that amount here. This amount will be added to your loan total, which can increase your monthly payments.
8. Calculate: After you’ve entered in your data, then hit the calculate button.

The auto loan calculator will display your estimated monthly payment and break it down into interest and principal.

Advanced Info

If you want to refine the estimate further, then you have the option to add more information.

The “Advanced Info” drop down, located just above the “Calculate” button, enables you to enter in more details.

• Sales tax rate: Enter in the percentage.
• Title costs and other fees: Enter in the dollar amount here.
• Ability to include or omit tax and fees in the loan amount: Select yes or no.

As you enter or adjust any of the values above, the estimated monthly payment will automatically be updated to reflect your changes.

Calculator output

The auto loan calculator will display your estimated monthly car payment in the pie chart to the right. In the tabs above the pie chart, you can explore more loan details. For instance, you can review balances over time or examine the split of estimated breakdown principal and interest paid each month in the amortization schedule. You can also review total interest paid, projected payoff date, and total loan cost information.

Making adjustments

You’re able to change any of these inputs on the fly to see how they impact your estimated monthly payments and total loan costs. For instance, by changing the loan term or adjusting the down payment, you see how these changes affect your payments and overall loan cost. By playing around with the inputs, you can compare different loan options to see what works best for you.

Remember:

While the auto loan calculator provides estimates, your actual terms may vary. Your credit score, income, and the lender's specific policies can influence the final terms of your auto loan. Use the calculator results as a guide to help inform your decisions and negotiations but be prepared for some variation when you apply for an actual loan.

• Avoid surprises: Get a clearer breakdown of estimated payments, interest, and additional costs like taxes and fees before you sign any loan agreements.
• Save time: See how adjustments to loan amount, interest rate, term length, or down payment impact your total loan cost—you might be surprised by what small changes can do.

Ways to save on your auto loan

Whether you're buying your first vehicle or looking to upgrade your current ride, understanding as much as you can about auto loans could save you money in the long run. Here are some tips that might help you secure more favorable loan terms:

Pay attention to total loan cost

When setting your spending limits, avoid focusing solely on the monthly payment—this can lead someone to paying much more in the long run. Rather, consider the total cost you want to spend over the lifetime of the loan. A low monthly payment might seem appealing, but it could mean a longer loan term with more interest paid over the course of the loan. And while an auto dealership might try to upsell you on features or more expensive models, keeping the big picture in mind may help you stick to your budget and ultimately make a smarter, more financially-sound decision.

It’s easy to determine how much you're willing to spend on an auto loan. Simply plug in your numbers in the auto loan payment calculator above to see how much you can afford and if there is space for it within your personal budget.

Compare loan offers from different lenders

It can pay to shop around. Get quotes from multiple lenders like banks, credit unions, online lenders, and car dealerships to get a better scope of offers and take the best one. Terms and rates vary by lender, so don’t just accept the first offer that you get.

Make a larger down payment

The more you pay upfront, the less you’ll need to borrow. A larger down payment can lower your monthly payment, reduce your interest costs, and improve your chances of qualifying for better loan terms.

Negotiate loan terms

Don't be afraid to negotiate with lenders. Use competing quotes as leverage to secure better terms.

Work on your financial health before you apply

Your credit plays a big role in determining the loan terms lenders will feel comfortable offering you—including which interest rates for which you qualify. Before applying, take some credit-related steps to ensure you're in the best position to get approved and secure favorable loan terms.

First of all, check your credit score to know where you stand. If your credit score isn't ideal, take the necessary steps to establish better credit habits before applying for a loan. You don’t need a high credit score to get a loan, but the lower your credit score, the less favorable loan terms can become.

Increasing your credit score substantially won’t happen overnight. Consistent good credit habits over time may help you achieve a healthier credit history.

Secondly, apart from getting the auto loan itself—which could lower your score—consider a few practical steps to potentially avoid a temporary credit score drop:

• Stay current on all payments, since payment history is an important score factor
• Keep your balances low, ideally maintaining your credit utilization under 30%
• Don’t close your oldest accounts, as length of credit history is an important score factor

Next, when rate shopping, keep in mind that each credit application typically results in a hard inquiry, which can slightly lower your credit score by signaling potential new debt. However, by submitting multiple applications within a short time frame—known as “bunching”—you can minimize the number of inquiries counted. The exact window depends on the credit scoring model used

Finally, get a copy of your credit report from all 3 credit bureaus: TransUnion, Equifax and Experian. You can go to AnnualCreditReport.com to get them for free each week. Once you obtain your report, look it over carefully to make sure the information is correct. You can dispute accounts that are inaccurate or result from fraudulent activity.
