On vinyl at 8 pass, 6 color mode at 100% coverage, would expect the total cost to be .22 psf - including ink, printhead and maintenance cartridge. The mix is .18 of ink, .03 for the PH (based on expected life of 4,000 ml) and .01 for maintenance cartridge (expected life of 14,000 ml). Also - above based on US list prices. The Embedded Web Server (EWS) will tell you your ink consumption to the ml for every job if you check it - and if you build out your cost assignment - can you give you an ink cost for every job - so you could actually do your own math if you want based on your actual prices etc. You could even build out your media portfolio to include media costs as well. You access the EWS by typing in the printer IP address into your browser. Hope this helps.
