Know Your Total Cost of Ownership

For color there's a bit more work. Divide the toner cost by the number of pages as you did for black: $356/12,000. The result is .0297, about 3 cents each. Now, two additional steps:

1) Multiply that .0297 by 3, because you have three color toners (cyan, magenta and yellow).

2) Add the cost of black to that, since, as you know, it takes all four colors to make a color print. So, .0297 x 3 + 1.3 = 10.21, about 10.2 cents in toner for one color print.
