How to calculate a car payment
A car payment is based on the amount you finance, the APR, and the number of months. For a $35,000 car with $5,000 down, 7% sales tax, and $800 in fees rolled into the loan, you finance about $33,250. At 7% APR over 60 months that is roughly $658 a month and about $6,250 in interest.
Stretching the same loan to 72 months drops the payment to about $567 but adds interest, so compare terms before you sign. Your lender sets the final rate based on your credit score, the vehicle, and the term.
How much car can I afford?
A common guideline is the 20/4/10 rule: put at least 20% down, finance for no more than 4 years, and keep total car costs under about 10% of your gross income. It is a guide rather than a rule, so adjust it to your budget.
Auto Loan Calculator FAQ

It can be. Many buyers finance sales tax and fees into the loan. Untick the option above to pay them upfront and see how the payment changes.
In most states, sales tax applies to the price minus the trade-in value. A few states do not allow this, so check your state rules.
No. It is an estimate for planning. Your lender sets the final APR, fees, and payment.
