Not going to claim to be an expert, but the short answer is that it isn’t negative.
There is a bit of a formula behind it, but even in the dealer calc you can see the Net Cap Cost @ $39K and then Residual Value at $36.5K. The depreciation portion of the lease is charge on that gap (please someone chime in if I am off).
I found this post from @delta737h which was helpful with Ohio-specific calculations since the taxes seem to cause me some trouble in my calculator. Leasing in Ohio - #6 by delta737h
I’d be wary of your dealer advertisement including the incentive programs are part of the ‘sale’ price. You need to make sure you have a clear understanding of their selling price pre incentives and rebates (see my calc in the 1st post).
