Car Payment Calculator

How to Calculate Your Car Payment

Your monthly car payment depends on four main factors: the vehicle price, your down payment, the loan term, and your interest rate (APR). A higher down payment and shorter loan term mean higher monthly payments but less total interest paid. Use our car payment calculator above to instantly see your estimated monthly payment and total cost of ownership.

For example, on a $30,000 car with $3,000 down, financed over 60 months at 6.5% APR, your monthly payment would be about $526. Over the life of the loan you would pay approximately $3,576 in interest on top of the purchase price.

What Is a Good APR for a Car Loan in 2025?

Car loan rates in 2025 vary significantly based on your credit score. Borrowers with excellent credit (750+) can typically qualify for rates of 4-6% APR on new cars. Good credit (700-749) typically sees rates of 6-9%. Fair credit (650-699) may face rates of 10-15% or higher. Credit unions typically offer lower auto loan rates than traditional banks or dealer financing.

The 20/4/10 Rule for Car Buying

Financial experts recommend the 20/4/10 rule: put at least 20% down, finance for no more than 4 years, and keep total car expenses (payment plus insurance) under 10% of your gross monthly income. This rule helps you avoid being upside-down on your loan and keeps car costs from straining your budget.

New vs Used Car: Which Is the Better Deal?

New cars come with full warranties, the latest safety features, and lower financing rates — but they depreciate roughly 20% in the first year alone. Used cars cost less upfront and depreciate more slowly, but may have higher maintenance costs and carry more risk. A certified pre-owned vehicle from a dealership offers a middle ground with inspection and limited warranty coverage.

From a pure financial standpoint, buying a 2-3 year old used car that has already taken the biggest depreciation hit is often the smartest move. You can get a nearly-new vehicle at a significantly lower price and still qualify for good financing rates if your credit is strong.

Should I Pay Cash or Finance a Car?

If you can get a low interest rate — say under 4% — financing can actually make financial sense even if you have the cash available, because you could invest that cash and potentially earn more than your loan interest rate. However, financing at higher rates of 8-15% or more makes paying cash the smarter choice if you have the funds.

Always get pre-approved for financing from your bank or credit union before visiting a dealership. This gives you a baseline rate to compare against dealer financing offers, and prevents the dealership from manipulating the monthly payment to obscure the true cost of the vehicle.

Complete Car Buying Guide for 2025

The car buying process begins long before you visit a dealership. Research the vehicle you want thoroughly — read owner reviews, reliability ratings from Consumer Reports and J.D. Power, and compare similar models. Knowing exactly what you want prevents dealers from upselling you to a more expensive trim level or a different vehicle entirely.

Get pre-approved financing from your bank or credit union before visiting any dealership. This is one of the most important steps many buyers skip. With pre-approval in hand, you know exactly what interest rate and payment you qualify for. When a dealer offers financing, you can compare it directly to your pre-approval. Dealers sometimes offer lower rates as a promotion, but they may also mark up your rate to earn profit on the financing.

Negotiate the vehicle price separately from the monthly payment. Dealers often focus conversations on monthly payment because it obscures the true cost of the vehicle. A dealer can make a $30,000 car seem affordable at $450 per month by simply extending the loan to 84 months — but you end up paying $37,800 total. Always negotiate the out-the-door price first, then discuss financing.

True Cost of Car Ownership

The sticker price is just the beginning. The true annual cost of car ownership includes your loan payment, insurance, fuel, maintenance, registration fees, and depreciation. AAA estimates the average new car costs over $12,000 per year to own and operate. Use our car payment calculator to understand your monthly loan payment, then budget an additional 50-100% of that amount for the other costs of ownership.
