Cartridge prices are easy to compare; what you actually pay is cost per page, and that depends on yield, coverage and what else the printer consumes. Here is a method you can do in a spreadsheet in ten minutes, with real numbers.
Step 1: cartridge cost per rated page
Take the price of the genuine cartridge and divide by the ISO rated yield printed on the box (ISO/IEC 19752 for mono, 19798 for color). Example, monochrome HP LaserJet Pro M404:
- HP 58A: 3,000 pages. At $119 that is 3.97 cents per page.
- HP 58X: 10,000 pages. At $230 that is 2.30 cents per page.
Same printer, same toner, 42% less per page with the high-yield cartridge. This is the single largest lever in most offices.
Step 2: adjust for your coverage
ISO yields assume 5% of the page is covered with toner — ordinary business text. Measure yours: on an HP, Reports > Supplies Status shows pages printed on the current cartridge; compare with the rated yield when it runs out. If a 3,000-page cartridge lasted 2,100 pages, your effective coverage is about 7%, and your cost per page is 3,000/2,100 = 1.43 times the rated figure. Logos, tables with shading and email signatures with images push coverage up fast.
Step 3: add the other consumables
- Paper: 20 lb copy paper at typical case prices is around 0.6–1.0 cents per sheet. Duplex halves it.
- Drum unit (only on separate-drum printers, e.g. HP M203/M227 with the 32A drum): drum price divided by drum yield, usually 0.3–0.6 cents per page.
- Fuser / maintenance kit: on office printers a kit rated 100,000–200,000 pages adds roughly 0.1–0.2 cents per page; on small printers there is no kit — the printer is replaced.
- Electricity and the printer itself: small per page for laser; include the printer's purchase price divided by expected pages if you are comparing printers rather than cartridges.
Step 4: color
A color page uses all four cartridges. Sum the per-page cost of each: for an HP Color LaserJet Pro M454 with 414A cartridges, black plus three colors is roughly 4 cents black + 3 × 3.5 cents color at rated yields, so about 14 cents per color page at 5% per color, and less for pages with only a small color logo. A 414A 4-pack lowers each cartridge's price by a few percent and keeps the set together.
Worked example: small law office
Monthly volume 2,500 pages, 90% mono text at about 6% coverage, one M404dn and one M454dw. Mono with 58X: 2.3 cents × 1.2 (coverage) + 0.8 cents paper ≈ 3.6 cents; 2,250 pages ≈ $81/month. Color 250 pages ≈ $35. Total about $116/month, or $1,400 a year — which is why moving from 58A to 58X (saving about $40/month) matters more than any one-time discount.
Canon example
Canon imageCLASS MF644Cdw with 054 cartridges (1,500 pages black) versus 054H (3,100 pages): the H version brings black cost per page from about 6.3 cents to roughly 4.2 cents at our prices. Same lesson: buy the high-yield version if the printer offers one and you print more than a few hundred pages a month.
Keep it honest
Recount every quarter: printers' actual pages per cartridge, paper spend and any reprints from quality problems. If a cheap "compatible" cartridge produced 20% reprints, its per-page cost was never cheap. Use the printer cartridge finder to see the standard and high-yield options for each printer model.

Frequently asked questions
How do I calculate toner cost per page?
Divide the cartridge price by its rated page yield, then adjust for your coverage: if your pages average 10% coverage, double the result. Add paper (about half a cent to a cent per sheet) and, for separate-drum printers, the drum cost divided by its yield.
What is a good cost per page for a laser printer?
For monochrome office printers with genuine high-yield toner, roughly 2–4 cents per page including paper is typical; small personal printers with low-yield cartridges can be 5–8 cents. Color pages commonly run 10–15 cents with genuine cartridges.
Why is the real cost higher than the cartridge math?
Rated yields assume 5% coverage. Real documents with logos, headers and images run higher, and every reprint counts. Track pages printed per cartridge for a few months to get your own number.
