What this calculator estimates
Trade-In Equity Calculator
Inputs and units
Use the units shown for Estimated trade-in value ($), Loan payoff balance ($), Replacement purchase price before sales tax ($), Additional cash down payment ($), Sales tax rate where the trade-in qualifies for a credit (%), Taxes and fees not offset by credit ($). Required fields cannot be blank. Use zero only where that field and the model allow it. Select Calculate after changing a scenario.
Method and assumptions
Trade equity is vehicle trade value minus its remaining loan. Assume the jurisdiction credits eligible trade value, capped at the replacement purchase price, against sales tax. Financed amount adds the purchase price, its full sales tax, fees and negative trade equity, then subtracts positive trade equity, cash down and the tax credit.
Worked example
A 42,000 purchase, trade value 26,000, old loan 18,500, cash down 3,000, sales tax 7% and fees 2,500 give equity 7,500, tax credit 1,820 and financing 35,120.
Limitations
Purchase price is before sales tax. This calculation assumes the trade qualifies for a full eligible tax credit; local rules may exclude or limit it. Fees are added after the calculated tax, and excess available credit is not a negative loan.
