The cost per page for any printer is calculated by dividing the cartridge price by its page yield and adding the cost of paper per page.
For the full breakdown, see our best Cost-Effective Printer guide.
Most people buy a printer looking at the upfront price, only to discover months later that the ink or toner costs more than the machine itself. Knowing how to calculate printer cost per page before you buy — or for the printer you already own — turns a hidden expense into a predictable number. The math is simple, but skipping a single component (like paper or a separate drum) can make your estimate useless. Here’s exactly how to do it right.
The Simple Way to Calculate Cost Per Page
For black-and-white printing, the formula is straightforward:
Cost per page = (cartridge price ÷ page yield) + paper cost per page
To find paper cost per page, divide the ream price by the number of sheets in one ream (usually 500). If a ream costs $10, paper adds $0.02 per page. The same logic applies to inkjet cartridges and laser toner — both use the price and the stated yield printed on the box or the manufacturer’s website.
For a real-world check, install a fresh cartridge, note the printer’s page counter, and divide the cartridge price by the actual pages printed before replacement. This beats the rated yield because real documents are rarely the standard 5% coverage used in manufacturer tests.
| Paper Type | Ream Price | Cost Per Page |
|---|---|---|
| Standard copy paper | $8.00 | $0.016 |
| Premium multipurpose | $12.00 | $0.024 |
| Photo paper (20 sheets) | $7.00 | $0.35 |
How to Calculate Cost Per Page for Color Printing
Color printing is where the math gets more involved because many color printers use multiple cartridges per page. The formula expands to include each color:
Color CPP = (black cartridge price ÷ black page yield) + sum of (each color cartridge price ÷ its page yield) + paper cost
If a printer uses separate cyan, magenta, and yellow cartridges plus black, you compute each one individually and add them together. Some printers also draw from the black cartridge on color documents, so include it every time. If the printer has a separate drum unit or maintenance kit, include that cost per page too: divide the drum’s price by its rated life and add it to the total.
What Most People Get Wrong About Cost Per Page
- Using the wrong yield figure. Standard-yield cartridges cost more per page than high-yield or XL versions, but all are rated differently. Always use the yield printed on the specific cartridge you buy.
- Forgetting paper. A penny here and there adds up fast. For a typical home office printing 200 pages a month, paper alone costs $3 to $4.
- Ignoring the drum or other consumables. Printers with separate toner and drum units need the drum cost per page added to the toner cost. Otherwise, your estimate is too low by 30% or more.
- Relying on the sticker price. A cheap $50 printer often uses expensive mini cartridges that bring CPP above 15 cents for black and 30 cents for color. A $200 printer with high-yield cartridges can print for half that.
- Not specifying OEM versus compatible cartridges. Third-party cartridges cost less upfront but often yield fewer pages. If you’re comparing options, calculate CPP separately for each supply type.
FAQs
What is considered a good cost per page?
For black-and-white laser printing, anything under 4 cents per page including paper is excellent. Color inkjet output under 15 cents per page is competitive. High-volume office printers often push color under 5 cents per page.
Does paper type affect cost per page?
Yes, significantly. Standard office paper adds about 1 to 2 cents per page. Glossy photo paper can add 15 to 35 cents per page or more, making it the largest cost component for photo printing.
How accurate are manufacturer page yield numbers?
Manufacturer yields are based on a standard test page with only 5% coverage — much less ink than a typical document. Real-world yields are usually 30 to 50% lower, especially for color pages with photos or heavy graphics.
