What "negative equity" means
Negative equity — sometimes called being "upside down" or "underwater" on a loan — simply means you owe more on your loan than the vehicle is currently worth. It's common, especially early in a loan term or after a vehicle depreciates faster than the loan balance comes down.
It's not a sign anything went wrong. New vehicles typically lose value quickly in the first couple of years, while a loan balance (especially a longer one) comes down more slowly at first. The gap between those two curves is negative equity.
Why it matters at a trade-in
When you trade in a vehicle, the dealer pays off your existing loan and the difference between what the car is worth and what you owe becomes part of the new deal. If you have positive equity, that difference reduces what you owe on the next vehicle. If you have negative equity, that shortfall typically gets rolled into the new loan — meaning you start the new loan already owing more than the new vehicle's price, unless you pay the difference out of pocket instead.
Why it matters for refinancing
A lender considering a refinance will generally look at the loan-to-value ratio — how much you owe compared to what the vehicle is worth. Significant negative equity can make refinancing harder to qualify for, or may still be worth doing if it lowers your rate even without changing the underlying balance.
Getting a sense of where you stand
You'll need two numbers: your current loan payoff balance (from your lender, not just the last statement) and a realistic estimate of what the vehicle is worth (a trade-in or private-party estimate from a source you trust). The Negative Equity Calculator takes those two numbers and shows the gap, plus what rolling a shortfall into a new loan would add to a future payment.
