Questions this tool helps answer
Compare the result, cost, and tradeoffs.
- What monthly payment results from the price, rate, term, down payment, rebate, and trade?
- How much interest will the loan cost over the selected term?
- How could additional principal change the payoff date and interest paid?
Method
How the calculation works
The calculator first determines trade equity, the selected sales-tax base, and the financed transaction balance. It then uses the standard fixed-rate amortizing-loan formula. A zero-percent loan divides principal by the number of payments.
Important definitions
Understand the result.
- Net trade equity
- Trade-in value minus the amount still owed. Negative equity increases the transaction balance.
- Amount financed
- Purchase price, tax, and financed fees, less cash down, rebate, and net trade equity.
- Additional principal
- An amount paid above the contractual payment that may shorten payoff when the lender applies it to principal.
Important limitations
Verify material decisions.
Actual lender calculations, sales-tax rules, fees, payment timing, prepayment treatment, and contract terms may differ. Verify the final transaction and loan documents before making a purchase decision.
Use the calculator as an educational comparison tool and confirm important figures with source documents, providers, lenders, taxing authorities, or qualified professionals as appropriate.
