Principal and interest on the amount financed. Taxes, title, registration, and insurance are extra — and a down payment or trade-in reduces the financed amount directly.

The car loses value faster than the loan pays down.
Watch the depreciation curve: two years in, a $15,000 vehicle is typically worth about $10,200 (−20% year one, −15% year two), and about $8,670 after three. With a 72-month loan at 7%, the balance is still $10,680 at month 24 and $8,282 at month 36, leaving you "underwater" by around $480 early on. That gap is why lenders push GAP insurance on long-term loans.

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 $15,000 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.
