How this calculator works

The auto loan calculator estimates your monthly payment, total interest, and payoff time using price, trade‑in, taxes/fees, APR, and term.

Key assumptions

Interest is compounded monthly using the stated APR.
Sales tax is applied to price minus trade‑in.
Fees are added to the financed amount.

Example

Example: $28,000 price, $3,000 down, 6.4% APR, 60 months. The calculator shows monthly payment and total interest; adding $50 extra reduces payoff time.

FAQs

Do I include trade‑in value? Yes—trade‑in reduces the taxable price and the amount financed.
What if I pay extra? Extra payments go to principal and reduce total interest.
Are fees required? Only if they apply to your loan; otherwise set them to $0.
