An estimate on the numbers you type, not an offer of credit or a quote from any dealership. Starting loan rates are Rateous's rates for each credit range and term; they are not an offer from any lender. The starting money factor, residual, and acquisition fee are starting figures only; the leasing company sets the real ones. The documentary fee starts at an example figure, the state's legal cap where it has one or $599 where it does not, not any dealership's fee; each dealership sets its own. 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.

The calculator needs JavaScript. How it works: a loan payment is the amount financed times the monthly rate, divided by one minus (one plus the monthly rate) to the power of minus the term. A lease payment is the depreciation (net capitalized cost minus residual, divided by the term) plus the rent charge (net capitalized cost plus residual, times the money factor), plus tax the way the state taxes a lease.
