How it is calculated
The yield quoted by the maker is usually for 5% coverage. Photos and solid fills empty a cartridge faster.
Page = cartridge / yield + paper
Where the numbers come from
- Cartridge
- Pages from the cartridge
- Paper per sheet
- Print run — unit in the field: p.
Example
A cartridge of 3 000 currency units for 1 500 pages, and paper at 0,5, gives 2,5 currency units per page.
Questions
Color and black?
Add the price of the cartridges that a page uses, or work them out separately and add the totals.
Double-sided printing?
If one sheet covers two pages, halve the paper price yourself.
A printer on installments?
Add its depreciation to the price of a sheet, in the paper field or as a sum of its own.
