Ink Coverage Calculator

Ink/toner cartridge yields are rated at 5% page coverage (industry standard). Actual usage varies with how much of the page is covered.

Formula:

• Adjusted yield = rated yield × (5% / actual coverage %)

Example: A cartridge rated for 2,000 pages at 5% coverage:

• At 10% coverage: 2,000 × (5/10) = 1,000 pages
• At 20% coverage: 2,000 × (5/20) = 500 pages
• At 2% coverage: 2,000 × (5/2) = 5,000 pages

Typical coverage levels:

Cost per page:

• Cost per page = cartridge price / adjusted yield
• Monthly cost = cost per page x pages printed per month

The price box starts empty on purpose. Cartridge prices move constantly, differ by country, and differ again depending on whether you buy the manufacturer’s own or a third-party refill, so there is no sensible number to pre-fill. Put in what you actually pay and the arithmetic is shown alongside the answer.

These are estimates. Actual yields depend on printer model, print quality settings, and content type. The 5% figure itself comes from a test standard, ISO/IEC 19752 for monochrome toner and 24711 for inkjet, measured on a fixed document at default settings. Draft mode stretches a cartridge; duplexing, photo paper settings and automatic head cleaning all shorten it. On an inkjet that sits idle between jobs, the cleaning cycles alone can use more ink than the printing does.

Ink coverage drives the real cost of printing, which is why it’s worth understanding before judging a printer or a cartridge. Manufacturers quote cartridge yields at a standard 5% coverage, roughly a normal text page, so a “500-page” cartridge prints far fewer pages of graphics-heavy or photo material. Your actual cost per page can be several times the headline figure once you print real documents.

Total Area Coverage matters for a different reason: there’s an upper limit. Because a full-color print layers cyan, magenta, yellow, and black, coverage on one page can pass 100% and climb toward 300% or more. Push too much ink onto a sheet and it won’t dry properly, it smears, or it cockles (warps) the paper, which is why commercial printers cap TAC, often around 240 to 300% depending on the press and the stock. Designers preparing files for print watch this number so dark, ink-heavy areas reproduce cleanly instead of turning into a wet, muddy mess.
