Car Lease Payment Calculator
This calculator breaks a car lease quote down to the numbers that actually set your payment: the net cap cost, the residual value, the term and the money factor. It splits the monthly figure into a depreciation fee and a finance fee, adds sales tax on the base payment, and shows the total. Use it to sanity check a dealer worksheet before you sign.
How to calculate a lease payment
- Enter the Net cap cost, the agreed price after any down payment or trade-in.
- Enter the Residual value the leasing company assigns at lease end.
- Set the Term in months and the Money factor from the dealer.
- Enter your Sales tax rate as a percent (leave it blank or 0 to skip tax).
- Read the Total monthly payment plus the depreciation fee, finance fee and monthly tax tiles.

Frequently asked questions
What is a money factor?
The money factor is the lease equivalent of an interest rate, written as a small decimal like 0.0025. Multiply it by 2400 to approximate the APR, so 0.0025 is roughly a 6 percent rate. A lower money factor means a smaller finance fee each month.
How is a lease payment calculated?
The base payment is a depreciation fee plus a finance fee. The depreciation fee is the cap cost minus the residual, divided by the term in months. The finance fee is the cap cost plus the residual, times the money factor. Sales tax is then applied to that base payment.
What is the residual value?
The residual is the vehicle's predicted worth at the end of the lease, set by the leasing company as a dollar figure. A higher residual means less value is used up over the term, which lowers the depreciation fee and your monthly payment.
What is the net capitalized cost?
It is the agreed price of the vehicle for the lease after any cap cost reductions such as a down payment, rebate or trade-in, plus any fees rolled into the lease. Enter the net figure, not the sticker price, for an accurate payment.
Why is the residual added inside the finance fee?
You are financing the average of the starting and ending value over the term. Adding the cap cost and the residual approximates twice that average, which is why the money factor is applied to the sum rather than to half of it.
How does the sales tax work here?
This tool uses the common payment tax method, applying your percentage to the base monthly payment and adding it on top. Some states tax the full sale price or the down payment instead, so confirm how your state taxes leases before relying on the tax line.
Does it include a down payment or fees?
Not directly. Fold a down payment or trade-in into the net cap cost by subtracting it, and roll acquisition or documentation fees into the cap cost by adding them. The calculator then works from that single net figure.
Is this an official quote?
No. It is an estimate to check a dealer worksheet, not a binding offer. Real contracts can add acquisition fees, disposition fees, registration and gap coverage, so your signed payment may differ from the number shown here.
Is my information kept private?
Yes. Every figure is calculated in your browser and nothing is sent to a server, so the prices and rates you enter never leave your device.
