So, going back to that 500 page cartridge example earlier... The way the printer industry tests each type of cartridge as a whole varies slightly, but as a general rule of thumb every printer cartridge is tested at 5% page coverage (the tests are different for colour vs black & white, and inkjet and laser style printers so it is a generalisation here).
Below we have included some visuals on what ~5% and what ~10% coverage look like respectively - and you decide what you are printing more of. If it is closer to the 10% example you can generally say that the cartridge will do half as many pages as the manufacturer state on the box (250 pages for our example here).
