New Car Depreciation: The Drive-Off Loss

July 1, 2026 • By the Investor Sam Editorial Team • Reviewed by Berly Sam Varghese, Editor
The most expensive mile a new car ever travels is the first one off the dealer lot. This tool shows the instant loss, whether your loan leaves you owing more than the car is worth, and the year the two lines finally cross.

Example: Car price: 40000 $ · Down payment: 4000 $ · Loan APR: 7 % · Loan term: 6 yrs · First-year depreciation: 20 % · Depreciation after yr 1: 15 %/yr

Underwater after year 1$0
First-year value lost$8,000
Car value after 1 year$32,000
Loan balance after 1 year$30,996
Year you break even1

Worked example

A $40,000 car with $4,000 down at 7% over 6 years is worth about $32,000 after year one, while you still owe roughly $30,600 — narrowly above water thanks to the down payment. Stretch the loan or skip the down payment and you can owe thousands more than the car is worth for years.

Frequently asked questions

Why do new cars depreciate so fast?

A car becomes "used" the moment it is titled, and buyers pay less for used. The first year typically erases 15–25% of value, with the decline slowing afterward. That is why a larger down payment matters so much.

What does being “underwater” cost me?

If the car is totaled or you must sell, you still owe the gap between the loan and the car value out of pocket. Gap insurance covers this, but avoiding a long, low-down loan avoids the problem entirely.

How do I break even sooner?

Put more down, choose a shorter loan term, or buy a model that holds value well. Each pushes the break-even year earlier, shrinking the window where you owe more than you own.
