People are often surprised to find that selling their car would not clear the loan on it.
It is not unusual, and it is not bad luck. It is arithmetic.
What you owe goes down on a schedule set by the loan. What the car is worth goes down on a schedule set by the market.
They are not the same shape.
A new car loses value fastest:
Slowly at first. Early payments are mostly interest, so the balance barely moves in the opening months.
Also front-loaded, in the opposite direction.
Value drops fast while debt drops slowly. For a while the two lines are the wrong way round.
That gap has a name.
On a typical loan the lines cross back over eventually, and after that the car is worth more than the debt.
The question is how long you spend on the wrong side.
Which widens the gap?
Tap an item, then a bucket
They lower the monthly payment, which is the number people shop on.
They also stretch the period during which the debt is bigger than the car.
If the car is written off or stolen, the insurer pays what it was worth — not what you owe.
The difference is yours, and there is no car.
Trading in while upside down usually means the shortfall is added to the next loan.
The gap does not disappear. It moves house and grows.
Not the monthly payment. The total you will have paid, and how fast the balance falls in the first year.
Both are on the paperwork, and neither is what gets advertised.
A car loses value fast at the start and a loan repays slowly at the start, so for a while you owe more than it is worth. Longer terms and small deposits make that stretch longer.
