Car Buying & Financing
Buying and Financing a Car Without Overpaying
This car buying and financing guide starts from one idea: the purchase price is only the start. Financing terms, timing, and negotiation tactics can each swing your total cost by thousands of dollars.

Why the sticker price is never the real story
Every car purchase is really three decisions stacked together: the negotiated price, the financing terms, and the timing of the sale. Getting one right while ignoring the other two is how buyers end up “winning” on price but losing on interest, or getting a great rate on a car they overpaid for. Work through all three, price, loan, and timing, before you sign anything. The FTC’s vehicle financing guide is a good independent starting point alongside this car buying and financing guide.
Where to start in this car buying and financing guide
Not everyone reading this is at the same stage. If you haven’t picked a car yet, start with New vs Used and Best Time of Year to Buy a Car before you get anywhere near a dealership. If you know what you want and are ready to talk price, go straight to How to Negotiate Car Price. If financing is the part you’re unsure about, whether that’s a first loan, a low credit score, or refinancing an existing one, the Auto Loan Guide, Bad Credit Financing, and Refinancing guides each cover a different version of that problem.
Whichever stage you’re at, this car buying and financing guide comes back to the same step: run your numbers through the Auto Loan Calculator before you sign anything. A calculator can’t negotiate for you, but it tells you within seconds whether the payment a dealer is offering actually matches the price and terms they quoted, which is often where the real cost gets buried.

Frequently asked questions
Is it better to buy new or used?
A used car (2-4 years old) usually offers the best value, since new cars lose roughly 20% of their value in the first year alone. New cars make more sense when you want the latest safety tech, a full warranty, and plan to keep the car a long time.
What credit score do I need for a good auto loan rate?
Lenders typically reserve their best advertised rates for borrowers with scores above 720-750. Scores in the 600s and below usually mean subprime rates, sometimes several times higher APR, which is why checking and improving your score before shopping can save thousands.
How much should I put down on a car?
Aim for at least 10-20% down on a new car and 10% on a used car if possible. A larger down payment reduces your monthly payment, cuts total interest, and helps avoid being underwater (owing more than the car is worth) in the first year or two.
What is the biggest mistake first-time car buyers make?
Focusing on the monthly payment instead of the total price and loan term. A dealer can hit almost any monthly number by stretching the loan to 72 or 84 months, which quietly increases the total interest you pay.
