I believe you are trying to give the "Total Cost of Acquisition"
 
Total cost of ownership goes far beyond Cost of Acquisition.
 
You have to consider maintenance, reliability, down time, resale value, and the cost of money plus other factors in a TCO analysis.

yeah but by all accounts the 24-120 isnt a very good lens especially vs the 24-105

perhaps doing it using the 24-70's and 70-200's

I agree, equivalent lenses are a tough call.  You also have to add the cost of NX2 if in the USA, DPP is included.  There is also the cost of tethering software for Nikon thats included with Canon.  If you want a eyepiece to help block out light from the sides, thats not included.  You do get a rear  LCD cover though.  I have never removed mine, I'm not certain if you are supposed to or not.

The Tamron 24-70 VC costs the same for both, doesn't it?

AF-S Nikkor 24-70/2.8	$1886
Canon 24-70/2.8 Mk II	$2299

I picked the Canon Mk II here because the Nikkor is a more recent lens (2007) and the Canon Mk I is ~10 years old and soon to be unavailable.

Lightroom costs the same for both DPP is really primitive in comparison.

Canon doesn't need that removable rear LCD cover - the LCD cover is built into the body on their DSLRs and is not that hard to replace. On Nikon cameras, without the LCD cover, the LCD is exposed.
