What this calculator estimates
Estimate positive or negative vehicle trade-in equity and how it may affect the amount financed on another vehicle. It is designed for fast planning and comparison in the United States. The output is an estimate, not a binding quote, approval, tax determination, insurance offer or professional recommendation.
How to use it
Enter the requested values using a single consistent time period and currency. Select Calculate, review the headline result and supporting figures, then change one assumption at a time to compare another scenario.
How the calculation works
Trade equity equals estimated trade-in value minus the loan payoff. Positive equity, cash and entered tax savings reduce the next amount financed; negative equity is added.
Important limitations
Dealer appraisal, payoff timing, state tax treatment, incentives, fees and lender limits can change the transaction. Some states do not provide the entered trade-in tax credit.
