Changing currency does not convert prices. Unit changes preserve the same physical quantities.
The acquisition fee is financed. Due at signing includes cash reduction, upfront tax and the first payment. Total lease cost includes your trade-in credit but excludes rebates, refundable deposits, registration, disposition, excess mileage and wear fees. The first payment is counted once.

Lease payment formula
Depreciation fee = (adjusted cap cost − residual) ÷ months. Finance fee = (adjusted cap cost + residual) × money factor. Their sum is the base payment. The Federal Reserve's consumer guide to vehicle leasing explains these parts: https://www.federalreserve.gov/pubs/leasing/resource/consider/ongoing_info6.htm . It also breaks down how each payment is built up: https://www.federalreserve.gov/pubs/leasing/resource/different/payments.htm
Signing and total cost
Adjusted cap cost adds the acquisition fee and subtracts cash, net trade-in and rebates. Total cost includes cash reduction, trade-in, all scheduled payments and upfront tax; rebates are not a personal expense. Tax inputs are estimates to reconcile with your lease quote.
How to use it
- Enter MSRP, negotiated price, reductions and the financed acquisition fee.
- Set the residual as a value or percentage of MSRP, then enter the money factor or APR equivalent.
- Choose monthly or upfront tax and compare the monthly payment, signing cash and total cost.

Frequently asked questions
How does the money factor relate to APR?
The comparison convention is APR equivalent = money factor × 2400, and money factor = APR equivalent ÷ 2400. It is not a disclosed loan APR.
Which sales tax option should I choose?
US states differ. Monthly mode taxes the base payment. Upfront mode taxes the taxable amount you enter from your quote; it does not infer your state's law. Reductions, exemptions and local fees may have separate tax treatment.
What is excluded?
Refundable deposits, registration, disposition, excess mileage and wear fees are excluded. The acquisition fee is financed, not paid a second time at signing.
