Auto Lease Calculator

The money factor is how lease interest is quoted — a small decimal such as 0.0020. Multiply it by 2400 to get the approximate equivalent APR; 0.0020 × 2400 ≈ 4.8%. A lower money factor means a cheaper lease. Dealers sometimes quote it without the leading decimal, so 2.0 may really mean 0.0020.

Residual value is what the leasing company expects the car to be worth at lease end, set as a percent of MSRP. A higher residual means less depreciation for you to pay, so a lower monthly payment. Cars that hold value well lease cheaply; cars that depreciate fast have low residuals and pricey leases.

Roughly, monthly ≈ depreciation fee + finance (rent) fee + tax. The depreciation fee is the adjusted cap cost minus residual, divided by the term. The rent fee is (adjusted cap cost + residual) × money factor. Tax is applied to that base payment. This tool shows each piece so you can see where the money goes.

A larger down payment (cap cost reduction) lowers the amount you finance, so it shrinks both the depreciation and rent portions and your monthly payment drops. But money put down on a lease is generally lost if the car is totaled or stolen early, so many advisors favor low- or zero-down leases.

No. This is a simplified estimate, not financial advice and not a binding quote. Real leases include acquisition and disposition fees, registration, dealer add-ons, and local tax rules this tool ignores. Use it to sanity-check a dealer’s numbers, then rely on the signed lease agreement for exact figures.
