How to Compute for Ink? Learn how to calculate ink requirements and costs for printing by considering ink usage, page coverage, cartridge yield, and the type of printer and document being printed.
How to Compute for Ink?
To compute ink usage or printing ink cost, divide the amount of ink used or the cartridge cost by the number of pages printed, then adjust for page coverage and the type of document. The exact calculation depends on whether you want to estimate ink consumption, cost per page, or total printing cost.
How to Calculate Ink Cost Per Page
If you know the cartridge price and its estimated page yield, use:
Ink cost per page = Cartridge cost ÷ Page yield
Example
Suppose:
Ink cartridge price = $30
Estimated yield = 600 pages
$30 ÷ 600 = $0.05 per page
So, the estimated ink cost is 5 cents per page.
Calculate the Cost of Printing Multiple Pages
Multiply the estimated cost per page by the number of pages:
Total ink cost = Cost per page × Number of pages
Information Example
Cartridge cost $30
Cartridge yield 600 pages
Ink cost per page $0.05
Pages printed 200
Estimated ink cost $10
How Page Coverage Affects Ink Usage
Printer manufacturers typically estimate cartridge yield using standardized testing conditions. Your actual results can vary because a page containing mostly text generally uses less ink than a page containing large graphics or photographs.
For example:
Document Type Typical Ink Usage
Light text document Low
Normal text document Moderate
Documents with graphics Higher
Full-page color graphics High
Photos Very high
Calculate Ink Usage Percentage
If your printer software reports remaining cartridge capacity, you can estimate the amount consumed.
For example, if a cartridge originally contains 100% ink and now shows 60%:
Ink consumed = 100% − 60% = 40%
This is only an estimate because printer-level ink indicators may not measure the remaining physical ink with perfect precision.
Calculate Ink Cost for Color Printing
Color printing can involve multiple cartridges, such as:
Black
Cyan
Magenta
Yellow
If you want to estimate the total ink cost, calculate each cartridge's cost per page and add them together.
Total color ink cost per page = Black cost/page + Cyan cost/page + Magenta cost/page + Yellow cost/page
Example
Cartridge Cost Yield Cost/Page
Black $25 500 pages $0.050
Cyan $15 700 pages $0.021
Magenta $15 700 pages $0.021
Yellow $15 700 pages $0.021
Total — — $0.113/page
This gives an estimated ink cost of about 11.3 cents per page under the assumed yields.
Ink Cost vs. Total Printing Cost
Remember that ink isn't the only printing expense.
Your total cost can include:
Ink or toner
Paper
Printer maintenance
Printhead replacement
Electricity
Cleaning cycles
Printer depreciation
A simple calculation is:
Total printing cost = Ink cost + Paper cost + Other printing expenses

Bottom Line
To compute ink cost, divide the cartridge price by its estimated page yield and multiply the result by the number of pages you plan to print. For more accurate budgeting, account for color coverage, photographs, paper, and other printer-related costs because actual ink consumption can differ from the manufacturer's estimated yield.
