Auto Loan Calculator: Car Payment, Tax & Trade-In
Estimate your monthly car payment with sales tax and a trade-in, then see total interest, amount financed, and a full amortization schedule. Compare 60, 72 and 84 month terms side by side. Everything runs locally in your browser.
How this auto loan calculator works
- Enter the vehicle price, your down payment and trade-in value, the APR, and the term in months.
- Add your sales tax rate. In most states a trade-in lowers the taxable amount, so the calculator taxes the price minus the trade-in unless you switch that off.
- It works out the amount financed (price plus tax and fees, minus down payment and trade-in), then applies the amortization formula for a fixed monthly payment.
- Compare common terms and open the schedule to see how each payment splits between principal and interest.
Example: a 30,000 car at 7% APR financed over 72 months runs
roughly 512 per month and about 6,832 in total interest.
Auto loan calculator FAQ
How much is a $30,000 car payment for 72 months?
A 30,000 dollar car financed at 7% APR for 72 months is about 512 dollars a month, before any down payment or trade-in. A bigger down payment or a shorter term lowers what you pay.
What is a good auto loan rate?
It depends on your credit and whether the car is new or used, but a good auto loan rate for new cars is generally around 5% or lower for strong credit, while used cars and weaker credit run higher.
Does a trade-in reduce sales tax?
In most states, yes. A trade-in usually lowers the sales tax you pay in most states because you are taxed on the price minus the trade-in value. A few states such as California do not give this credit.
What is a car note?
A car note is simply another name for your monthly car loan payment. It is the fixed amount you pay each month until the loan is paid off.
Should I choose a 72 or 84 month car loan?
An 84 month loan lowers the monthly payment but increases the total interest you pay, since you borrow for longer. A shorter 60 or 72 month term costs more each month but less overall.
