How to use the auto loan & car payment calculator
What the car payment includes
First subtract your down payment and net trade-in equity from the vehicle price. Add estimated sales tax and fees. Amortize the financed balance at the chosen APR over the number of months.
Why trade-in equity matters
Trade-in equity is the value of your trade minus the outstanding balance owed. Negative equity increases the amount financed.
Important assumptions
This model applies sales tax to the full vehicle purchase price, without a trade-in tax credit. Actual tax rules, lender fees, rebates, warranties and insurance vary by location and contract. Verify your state’s rules and the final dealer worksheet.
Sources & next steps
The calculator uses the numbers you provide and the assumptions explained above. Verify important inputs using your records or independent references.
