Negative Equity Rollover Calculator

Owe more than the trade is worth? Squint at what rolling that balance into a new loan really costs — including how much of every payment goes to a car you no longer own.

1 · The car you're trading

You're upside down by $4,500 — this rolls into the new loan.

2 · The new deal

What you're actually financing

$84.51 of every $657.03 payment services the old car, and you'll pay roughly $1,584 in interest on debt from a vehicle you no longer drive.

Assumes your state gives a trade-in tax credit (tax charged on price minus trade value) — a state toggle ships at launch. Day-one equity assumes the new vehicle is worth what you paid; real depreciation makes the position worse. Estimates only.

How rollovers snowball

Rolling negative equity forward means financing a car you no longer own inside the loan for one you do. Done once, it is sometimes a defensible trade-off; done twice, the hole compounds — each rollover starts the next loan deeper underwater, and GAP coverage stops being optional. The calculator above shows the honest split so you can decide with the number in front of you.
