Auto Lease Calculator
Estimate your monthly lease payment from cap cost and residual value.
How to use the Auto Lease Calculator
The Auto Lease Calculator is free and runs entirely in your browser — no sign-up, and nothing you enter leaves your device. It opens pre-filled with a realistic example, so you can see how it works before replacing any figure with your own; the results update as you type. Press Calculate to refresh the result panel, or Reset to return to the example.
The inputs it asks for:
- Negotiated Price (Cap Cost) — a dollar amount.
- Down Payment / Cap Reduction — a dollar amount.
- Residual Value % — a percentage (enter 6 for 6%).
- Money Factor (e.g. 0.00125) — a number.
- Lease Term (Months) — a number.
- Sales Tax Rate — a percentage (enter 6 for 6%).
