Estimate car financing after tax, down payment and trade-in value.
UNDERSTAND THE ANSWER
How is this calculated?
Sales tax is added to the vehicle price, then cash down and trade-in value reduce the financed balance. Registration, documentation and dealer fees are excluded.
Amount financed and paymentFinanced = Price + Tax − Down payment − Trade-in
A practical example
A $38,000 car with 6% tax, $5,000 down and a $3,000 trade-in finances $32,280 before dealer fees.
Assumptions, interpretation and common mistakes
Calculation assumptions
Sales tax is applied to the entered vehicle price.
Down payment and trade-in reduce the amount financed.
Registration, documentation, warranties and dealer add-ons are excluded.
How to interpret the result
The estimated payment covers the financed vehicle balance and interest.
Amount financed shows the balance after the entered tax, cash and trade-in.
Total loan payments exclude the upfront down payment and trade-in value.
Common mistakes to avoid
Negotiating only on monthly payment instead of total vehicle price.
Ignoring dealer fees, negative trade-in equity or add-ons.
Extending the term beyond the period you expect to keep the vehicle.
