29.1 Percent of Financed Trade-Ins Underwater in Q3 2026, Negative Equity Averages $7,107

Edmunds recorded the third-quarter underwater share at 29.1 percent, down from 30.9 percent in January but above 28.1 percent a year earlier. Average negative equity reached the highest third-quarter level in a decade, exceeding pre-pandemic norms of $5,000-$5,500. Borrowers who rolled balances financed $12,600 more than typical new-car buyers and faced $165 higher monthly payments at 8.1 percent interest. Over 91 percent chose terms of 72 months or longer, extending the period before equity turns positive.

The pattern traces to 2021-2022 purchases made when used-vehicle prices peaked amid supply constraints. Equity positions deteriorated once production recovered and values normalized. JD Power projects 29.6 percent underwater trade-ins for October, with average new-vehicle payments reaching a record $823. Lenders accommodate stretched terms to sustain volume, yet longer amortization slows principal reduction and raises total interest paid by roughly 83 percent versus 2019 levels.

State and regulatory incentives favor continued lending at current rates because capital requirements treat auto paper as lower risk than unsecured consumer debt. Manufacturers gain from higher transaction prices that support margins, while borrowers trade immediate mobility against rising rollover costs. Primary records from Edmunds and JD Power show no reversal in loan-length distribution, indicating structural acceptance of extended negative-equity cycles.

Absent policy shifts on capital rules or rate paths, the share of underwater trade-ins is projected to remain above 28 percent into 2027, with average financed amounts continuing to rise.
