Calculate your monthly car payment based on vehicle price, down payment, interest rate, and loan term. Includes trade-in value and taxes.
Input the car's purchase price before taxes and fees.
Enter cash down payment plus trade-in value. Compare a 20% scenario to reduce upside-down loan risk.
Input interest rate (check your credit score first) and desired loan term (36, 48, or 60 months recommended).
See monthly payment, total interest paid, and total cost including taxes and fees.
This checklist is more useful than focusing only on the dealer's monthly payment.
Add insurance, fuel, maintenance, and registration before judging the monthly payment.
Compare 48, 60, and 72 months so you can see the real interest tradeoff.
If a long term is the only way to make the payment fit, the car is probably too expensive.
Show up with a pre-approval so you can negotiate from a stronger position.
| Factor | New car | Used car |
|---|---|---|
| Depreciation | Largest hit up front | Biggest drop already happened |
| Warranty | Full coverage | Often shorter or limited |
| Promo APR | More common | Less common |
| Insurance | Often more expensive | Often lower cost |

Complete your financial planning with these tools
Your biggest edge in a car purchase is knowing your limit before you negotiate.
These tools help you check whether a new car decision makes sense alongside the rest of your finances.
Make sure the payment fits your monthly cash flow.
Check whether cleaning up debt first changes your best move.
Do not finance a car without room for unexpected repairs.
Translate a job offer into realistic take-home pay before you buy.
Good car loan rates in 2025 range from 4-7% for new cars and 5-9% for used cars, depending on your credit score. Excellent credit (750+) can get rates as low as 3-4%, while fair credit (600-699) might see 8-12%.
Both dealer financing and bank/credit union loans have different advantages. Dealers may offer promotional rates while banks may provide competitive standard rates. Compare all options and terms for your situation.
General guidelines suggest keeping total vehicle costs under 10-15% of income. For educational purposes, this might mean $400-625/month on a $50,000 salary. Individual circumstances vary - consider your complete financial picture.
A good down payment for a car is typically 20% of the purchase price for a new car and 10% for a used car. A larger down payment can help you get a lower interest rate and reduce your monthly payments.
Refinancing a car loan can temporarily lower your credit score by a few points due to the hard inquiry on your credit report. However, making timely payments on the new loan can help improve your credit score over time.
Yes, it is possible to get a car loan with bad credit. However, you will likely have a higher interest rate and may need to provide a larger down payment. It is important to shop around and compare offers from different lenders.
GAP insurance covers the difference between what you owe on your car loan and what your car is worth if it is stolen or totaled. It is not required, but it can be a good idea if you have a long loan term or a small down payment.
Excellent credit often lands near 3-5%, good credit near 5-8%, and fair credit can run 8-12% or higher. Rates also vary by lender, vehicle age, and loan term.
A practical starting point is to keep total transportation costs, not just the loan payment, near 15-20% of take-home pay. That includes insurance, fuel, maintenance, and registration.
Used cars often win on value because the largest depreciation hit already happened. New cars can offer lower promo APRs and full warranty coverage, so compare both monthly payment and total ownership cost.
Shorter terms like 36-48 months usually cost less overall but raise the monthly payment. Longer terms like 72-84 months lower the payment but can leave you underwater longer.
Compare bank or credit union financing estimates first, then compare those offers with the dealer's financing. Promo rates can be good, but dealer markups on standard loans are common.
A 20% down payment for new cars and 10% for used is a solid target. More down reduces payment, interest, and the risk of owing more than the car is worth.

Buying a car is the second largest purchase most people make after a home. Yet many buyers focus solely on whether they can make the monthly payment, ignoring the true cost of ownership. Our car affordability calculator helps you determine not just what you can finance, but what you can actually afford without straining your budget or jeopardizing your financial goals.
Your interest rate is the single biggest factor affecting your car's total cost. Even a 1% difference can mean thousands over the loan term.
A larger down payment reduces your monthly payment and total interest paid. Here's how different down payments affect your loan:
Often offer competitive rates, especially for members. Compare a bank or credit union estimate before shopping so you have a benchmark for dealer financing. Credit unions may offer rates 1-2% lower than banks.
Convenient but often more expensive. Dealers mark up rates to make profit. However, manufacturers sometimes offer 0% promotional rates on new cars. Always compare with outside financing.
Growing option with competitive rates. Quick approval process and rate shopping doesn't hurt your credit if done within 14-45 days. Good for comparing multiple offers quickly.
Leasing offers lower payments but you never own the car. Best for those who drive under 10,000 miles/year and want a new car every 2-3 years. Buying is better for long-term value.
Review your credit report for errors. Dispute any mistakes and pay down credit cards to improve your score.
Shop rates from multiple lenders. This tells you exactly what you can afford and gives negotiating power.
Narrow down to 2-3 models. Check reliability ratings, safety scores, and real-world fuel economy.
Email multiple dealers for their best price. Use online services to get competitive quotes without visiting showrooms.
Focus on total price, not monthly payment. Be prepared to walk away if the deal doesn't meet your budget.
Read all paperwork carefully. Verify the interest rate, term, and total cost match what you agreed to.
Once you've purchased your car, protect your investment and minimize long-term costs:
