Note: Sales tax rules vary by state/country. This tool assumes tax is applied to the selected base and that down payment reduces only the amount financed.
How to use
- Enter vehicle price, then add any down payment, trade-in, rebates, and fees.
- Set sales tax % and choose the tax base (price only vs. price minus trade-in/rebates).
- Choose APR, term, and payment frequency (monthly/biweekly).
- Optionally add extra principal per period to pay off faster.
- See amount financed, payment, total interest, and export the amortization CSV. All calculations run locally.
