Calculate your monthly car payment and total interest.
Open the Interactive CalculatorHow It's Calculated
Amount Financed = Vehicle Price − Down Payment − Trade-In + Sales Tax (applied to price minus trade-in in most states). Monthly Payment uses the standard installment loan formula.
Example
Example: a $32,000 vehicle with $4,000 down, no trade-in, and 6.5% sales tax finances about $30,080. At 7.5% APR over 60 months, that's roughly $603/month, with about $6,100 in total interest.
Frequently Asked Questions
Does trade-in value reduce sales tax too?
In most states, yes — sales tax is applied to the price after subtracting trade-in value, which this calculator assumes.
Why does a longer term lower my payment but cost more overall?
Spreading the loan over more months reduces each payment, but you pay interest for longer, increasing total interest paid.
