Please note that this tool is currently in beta testing

LeaseScope (currently in beta testing) replaces the old Reverse Calculator by focusing on what lease ads actually reveal today.
Instead of trying to extract a “true” money factor or residual—which manufacturers now hide behind incentives, dealer contributions, and rolled-in fees—LeaseScope calculates the effective MF, provides a clear program score, and flags when high DAS (Due at Signing) likely includes a down payment. This tool is designed to evaluate the quality of a lease offer, not decode every hidden element behind it.

LeaseScope
Lease Program Analyzer

LeaseScope analyzes the underlying lease program using the numbers from a national offer. It estimates Effective MF, residual %, OEM support, and a 1–10 score. It does not model your personal taxes, credit tier, dealer add-ons, or any Customer Cash Reduction (CCR) you choose to add. High Due At Signing (DAS) amounts may indicate that part of the deal is a down payment (CCR) rather than pure fees.
Use the MSRP shown in the ad. This anchors residual % and support.
Net / Adjusted Cap Cost from the ad. ACC already reflects factory incentives and dealer contribution.
Enter the advertised monthly payment. You can flag if it includes tax below.
Use the term shown in the national ad (often 36 or 39).
The buyout at lease end from the ad. Required to estimate Effective MF.
Total DAS from the ad. LeaseScope does not roll DAS into ACC. DAS above about $2,500 often means you’re putting real money down (CCR) rather than just paying fees.

The calculator ignores customer cash or CCR, taxes, dealer fees, and DMV costs, focusing only on the underlying program quality—not your personal deal. LeaseScope does not report the manufacturer’s official base MF; instead, it reveals the effective MF after all incentives and adjustments, which is the only number that reflects what you actually pay.
