Frequently Asked Questions
What is negative equity on a car?
Negative equity means the current loan payoff is greater than the vehicle trade value. The difference may need to be paid in cash or financed into a replacement loan, subject to lender terms.
How much negative equity can be rolled into a car loan?
There is no universal amount. Lenders may apply loan-to-value, credit, vehicle, income, and other underwriting rules. This calculator only models the user-entered amount and does not predict approval.
Does trading in a car with negative equity raise the next payment?
Rolling the shortfall into a replacement loan increases the amount financed. The additional payment and interest shown here depend on the entered price, cash down, rate, and term.
How Negative Equity Changes a Trade-In Loan
A trade-in shortfall can follow you into the next loan, but the exact outcome depends on the values and financing terms you enter.
How the calculation works
Equity equals trade value minus the current payoff. Negative equity is the amount by which the payoff exceeds the trade value. The replacement amount financed adds that shortfall to the replacement purchase costs.
- Cash down reduces the amount financed.
- Positive equity is modeled as a reduction to replacement financing.
- The comparison removes rolled negative equity while keeping other inputs constant.
Methodology and limitations
This deterministic estimate uses your inputs for vehicle value, payoff, price, taxes, fees, rate, and term. It does not estimate approval, lender loan-to-value limits, taxes, trade credits, registration charges, or actual dealer figures.
- Trade values and payoff quotes can change before closing.
- A lender may require cash down instead of allowing all negative equity to be financed.
- The calculator does not recommend whether to trade, sell, or keep a vehicle.
Ways to reduce a shortfall
You can compare waiting to build equity, bringing cash to closing, choosing a less expensive replacement, or obtaining an exact payoff and trade appraisal before signing.
