An estimate on the numbers you type, not an offer of credit or a quote from any dealership. Starting loan rates are the average new-car APR for each credit tier (used-car APR for a used car) from Experian's State of the Automotive Finance Market, second quarter 2026, VantageScore 4.0. The starting money factor, residual, and acquisition fee are starting figures only; the leasing company sets the real ones. Taxes and state fees are estimates for Arizona; the dealership's paperwork and your motor vehicle agency have the final numbers. What you own at the end assumes the car is worth the residual. Nothing you type is sent, saved, or used to check your credit.
