🚗 Understanding Your Auto Loan

Purchasing a vehicle is a significant decision, and understanding your auto loan is an important factor that must be considered while making a wise decision. Our calculator allows you to calculate how much you can afford to pay each month or how much you can borrow, considering all factors that influence your auto loan.

Regardless of whether you are purchasing a brand new vehicle or a used one, it is important to understand that it is not just the price of the vehicle that influences your auto loan. The other factors that influence it include how much you are willing to pay as a down payment, trade-in value, interest rates, sales tax, and fees.

📊 Key Factors Affecting Your Car Payment

Vehicle Price & Down Payment

The price of the car, less your down payment and trade-in, equals the loan amount. The more you put down as a down payment (20% or more), the less your monthly payment will be, as well as avoiding being "upside down" on the loan.

Interest Rate (APR)

The interest rate on your car loan depends on your credit rating, loan term, and whether the car is new or used. Even a 1% difference in APR can save or cost you thousands over the term of the loan. In general, new cars have a lower APR than used cars.

Loan Term Length

Typical car loan terms range from 36 to 84 months. The longer the term, the lower your monthly payment, but the more interest you pay over the term. For example, a 72-month car loan can cost you as much as $1,000+ more in interest than a 60-month loan on the same car.

Taxes & Fees

Sales tax (which varies by state), title fees, registration fees, as well as dealer documentation fees, can add thousands to your loan. Our car loan payment calculator can take these into account to give you a more accurate calculation.

💡 Smart Auto Loan Strategies

1. Improve Your Credit Score Before Applying

Your credit score plays a huge role in determining the interest rate you pay on the loan. A credit score above 720 earns you the best rates, but if your score is below 660, you'll pay significantly high rates.

2. Get Pre-Approved Before Shopping

Getting pre-approved from your local bank or credit union gives you the power to negotiate with the car dealer. This is because you'll know the upper limit you can spend and won't be forced into a bad deal from the lender. Be sure to compare at least 3-5 lenders to get the best rate.

3. Negotiate Price, Not Payment

The salesperson likes to concentrate on monthly payments because it is more difficult to disclose the true cost. It is better to negotiate on the total cost of purchase, then on finance. It is important to be aware of the true cost of a vehicle by checking sources such as Kelley Blue Book or Edmunds.

4. Think About Total Cost of Ownership

The monthly payments are just part of the total cost. It is important to think about other expenses such as insurance (this varies greatly by model), fuel efficiency, maintenance, and depreciation. It is possible that a more expensive vehicle could be cheaper to own than a cheaper one that has high maintenance and insurance expenses.

5. Don't Fall For Extended Warranties and Extras

The salesperson can make a lot of money on extended warranties, paint protection, and fabric protection. These are usually unnecessary and can be negotiated. If you want an extended warranty, it is better to buy it elsewhere, as you could save 50% or more.

❓ Common Auto Loan Questions

What credit score do I need for a car loan?

While you can qualify with a credit score as low as 500, the lowest interest rates are only available to those with scores over 720. Those with scores ranging from 600 to 660 qualify, but pay much higher interest rates. Boosting your credit score by just 50 points can save you thousands over the life of the loan.

How much should I put down on a car?

Financial experts recommend putting at least 20% down on a new car and at least 10% down on a used car. This helps prevent negative equity and reduces your monthly payment. If you cannot put at least 20% down on a car, consider a less expensive car or waiting until you have more money.

Should I finance through the dealer or my bank?

It’s a good idea to get pre-approved at your bank or through your credit union. This way, you have a baseline to compare. While car dealerships may have special offers such as 0% APR, they also have the ability to raise interest rates to maximize their profit margin.

Can I pay off my car loan early?

Yes, most car loans do not have early pay-off penalties. In fact, if you have the means, making extra principal payments on your loan can save you a significant amount of money in interest. Even an extra $50 to $100 per month can save you several months on your loan.

What is the difference between new and used car loan rates?

New cars have lower interest rates, which can be 1-2% lower than used cars. This is because new cars pose less risk. Used cars lose their value at a slower rate, which can actually work in your favor even if the interest rate is higher.
