The car loses value faster than the loan pays down.
Cars depreciate faster than long loans amortize. A typical new vehicle loses about 20% of its value in year one and roughly 15% a year after that — so a $40,000 car is worth around $27,200 after two years. On a 72-month loan at 7% you'd still owe about $28,479 at that point — roughly $1,279 of negative equity. Shorter terms and bigger down payments keep the balance under the car's value.

Model your own rate, term, and extra payments
The interactive loan calculator handles any APR and term, shows the full amortization schedule, and lets you test extra payments against the balance.
How these numbers are calculated.
Payments use the standard amortization formula with monthly compounding on $40,000 financed. APRs shown (5%–9%) are illustrative steps spanning typical 2026 prime/near-prime pricing, not offers.
Depreciation figures use a typical curve — about 20% loss in year one and 15% per year thereafter — applied to the financed amount as a proxy for vehicle price with zero down. Individual models vary widely.
Figures exclude sales tax, title/registration fees, dealer add-ons, and insurance. Educational estimates — not lending or financial advice.
