What is Auto Lease Calculator?
The Auto Lease Calculator estimates your monthly lease payment using the same formula dealers use: depreciation on the capitalized cost plus a rent charge based on the money factor, plus sales tax. It also totals the rent charge and the whole lease so you can judge the deal, not just the payment.
Key Benefits
- See the real monthly number before entering the dealership
- Understand how much of the payment is interest (rent charge)
- Total lease cost view exposes padded fees and markups

Common Use Cases
- •Checking dealer lease worksheets for padded money factors
- •Comparing lease offers across models and trims
- •Deciding between a larger down payment and more months
- •Estimating business vehicle leasing costs
