Calculate your monthly car payment instantly. Adjust price, down payment, interest rate, and loan term to find the perfect budget.
Your car payment should be no more than 10-15% of your monthly take-home pay.
Aim for a 20% down payment to avoid being "underwater" on your loan.
Shorter terms mean less interest paid. Avoid 72-84 month loans if possible.
A higher credit score qualifies you for lower interest rates, saving thousands over the loan term.
More money down means borrowing less and paying less interest overall.
Compare rates from banks, credit unions, and dealers. Even 0.5% difference adds up.
A reliable used car can be just as good and save you thousands upfront and monthly.
Car payments use an amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where M is the monthly payment, P is the principal (loan amount), r is the monthly interest rate, and n is the number of payments. This ensures equal payments that cover both principal and interest.
For buyers with excellent credit (720+), expect rates of 4-6% for new cars and 5-7% for used. Good credit (680-719) typically sees 6-8%, while fair credit (640-679) may pay 9-12%. Always shop around - rates vary significantly between lenders.
While longer terms (72-84 months) lower your monthly payment, you'll pay significantly more in interest and risk being "underwater" (owing more than the car is worth). If budget allows, stick to 48-60 months.
Get pre-approved from your bank or credit union first - it gives you negotiating power. Then compare to the dealer's offer. Dealers sometimes offer promotional rates (like 0% APR) that beat bank rates, but read the fine print carefully.
Know what you're paying for before you commit.
