Vehicle Lease Payment Calculator

The calculator uses the standard lease formula: depreciation cost plus a finance charge based on the money factor, then applies sales tax. It also computes an equivalent loan payment by amortizing the same principal over the lease term using the provided APR (or zero‑interest if APR is 0). The difference shows which option saves you more money over the term.

Enter the manufacturer’s suggested retail price of the vehicle in dollars.
Percentage of MSRP that will be owed at lease end, as a percent (e.g., 55 for 55%).
How many months the lease lasts.
The lease’s finance charge expressed as a monthly decimal ratio (e.g., 0.0015 equals 1.8% APR). It is calculated by dividing the advertised APR by 1200.
Cash paid or trade‑in value used to lower the capitalized cost, in dollars.
Local sales tax applied to each lease payment, as a percent (e.g., 8 for 8%).
Annual percentage rate used if buying the vehicle instead of leasing. Set to 0 if no financing interest is applied.

What it is

A vehicle lease payment calculator transforms the raw numbers that appear on a dealership’s contract—MSRP, residual value, money factor, down‑payment and sales tax—into the precise monthly lease cost you’ll owe each month. It applies the standard leasing formula: depreciation cost (the drop from capitalized cost to residual) plus a finance charge based on the money factor, then adds taxes. Importantly it also generates an equivalent loan payment by amortizing the same principal over the same term using the selected APR. This dual output lets buyers directly compare the total cost of leasing versus buying, revealing which option saves more cash and clarifying how each input (e.g., higher residual, lower money factor) shifts the balance.

How to use it

Enter the vehicle’s MSRP in dollars, the residual value percentage you expect at lease end, the desired term in months, and the quoted money factor. Specify any upfront payment or trade‑in amount and your local sales tax percent. For a loan comparison input the annual APR—zero if you’re assuming no interest. After pressing calculate, review the monthly payments, total costs and the difference to decide which financing route is cheaper for you.

Worked example

First compute the capitalized cost: 30,000 – 2,500 = 28,000 USD. The residual value is 55% of MSRP → 16,500 USD. Depreciation per month = (28,000 − 16,500)/36 = 305.556 USD. The finance charge uses the money factor: (28,000 + 16,500) × 0.0015 = 66 USD. Lease before tax = 305.556 + 66 = 371.556 USD. Sales tax at 8% adds 29.724 USD, giving a monthly lease payment of 401.280 USD. Over 36 months the total lease cost is 401.280 × 36 = 14,446.080 USD.

For a loan comparison the principal equals the same amount after down‑payment: 28,000 USD. With zero APR the monthly payment is simply 28,000 / 36 ≈ 763.889 USD. Over 36 months the loan cost totals 27,500.000 USD. The difference—lease minus loan—is –13,053.920 USD, meaning leasing saves that amount over the term.

Frequently asked questions

What if my money factor is given in APR instead of decimal?

Convert by dividing the APR by 1200 to obtain a monthly money factor (e.g., 3.6% APR → 0.003).

Do I include down‑payment in loan calculation?

Yes—the initial cash lowers both lease capitalized cost and loan principal.

Can I use this calculator for commercial leasing arrangements with variable rates?

The tool assumes a fixed money factor (and APR). For variable rates, you’ll need to input the average expected rate or calculate monthly balances separately.
