Looking for a auto loan calculator with tax and trade-in? This free tool gives you true monthly payment including sales tax, fees and trade-in value. Just enter your numbers and press Calculate — results are instant.
The true cost of a car loan is not just the sticker price. Sales tax is charged on the price after any trade-in, and title and registration fees are added too; then the down payment comes off, and what is left is the amount you actually finance. Enter the price, trade-in, tax rate, fees, down payment, term and rate, and the calculator gives the real monthly payment, the tax, the total interest, and the total cost including your down payment.
Example: Vehicle price $35,000 · Down payment $5,000 · Trade-in $0 · Sales tax 7% · Fees $400 · Term 5 years · Rate 7.5%
Monthly Payment: $658.25
A bigger down payment means a smaller loan, a smaller monthly payment and less interest — but do not empty your emergency savings to do it. A down payment of about 20% is a common target for a car.
In many places, yes: tax is charged on the price after the trade-in value is subtracted, and this calculator does exactly that. Rules differ by state, so check your local rule if you want an exact figure.
Shorter terms cost less interest but have higher payments. A 5-year loan is a common middle ground; stretching to 7 years lowers the payment but you pay much more interest and the car may be worth less than you owe for a long time.
