How to Calculate the Cost per Page of Your Printer

The basic printer cost-per-page formula

The simplest way to calculate printer cost per page is to divide the cost of a consumable by the number of pages it is rated to produce:

Cost per page = consumable price ÷ rated page yield

For example, a $60 cartridge rated for 1,500 pages would cost approximately $0.04 per page, or 4 cents. This is a consumables estimate, not a guarantee of what every user will pay.

The calculation works best when you use the current price and the exact cartridge model made for your printer. Cartridge prices change, and page yields are estimates based on standardized testing rather than a promise that the cartridge will produce the same number of pages in your home or office.

How to calculate cost per page step by step

1. Identify the exact cartridge or supply

Check the printer’s manual, cartridge packaging, or official product page for the correct supply model. Do not mix standard-yield, high-yield, and XL cartridges in the same comparison without noting the difference.

You should also confirm whether the printer uses separate black, cyan, magenta, and yellow cartridges or a combined color cartridge. Laser printers may use separate drums, fusers, transfer belts, or waste-toner containers in addition to toner.

2. Find the current purchase price

Use the current price from the manufacturer or a retailer. Record the date if you are comparing printers, since supply prices can change over time.

For a useful comparison, compare cartridges under similar conditions. A low purchase price does not necessarily mean a lower cost per page if the cartridge has a smaller yield.

3. Find the rated page yield

Look for the cartridge’s stated page yield in the printer documentation, on the manufacturer’s supply page, or on the packaging. Make sure the yield applies to the exact cartridge and printer model.

Manufacturers calculate yields using specified test methods. ISO/IEC 24711 covers a method for measuring color-ink cartridge yield, while ISO/IEC 19798 covers color electrophotographic toner cartridges.

4. Divide price by yield

Use this formula:

Cartridge cost per page = cartridge price ÷ rated page yield

If a cartridge costs $60 and has a rated yield of 1,500 pages:

$60 ÷ 1,500 = $0.04 per page

To express the result in cents, multiply the dollar amount by 100. In this example, $0.04 equals 4 cents per page.

How to calculate color printing cost

A color printer typically uses multiple supplies, so a color cost-per-page estimate requires more than the black cartridge price.

For a printer with separate black, cyan, magenta, and yellow cartridges, calculate each cartridge individually:

• Black CPP = black cartridge price ÷ black cartridge yield
• Cyan CPP = cyan cartridge price ÷ cyan cartridge yield
• Magenta CPP = magenta cartridge price ÷ magenta cartridge yield
• Yellow CPP = yellow cartridge price ÷ yellow cartridge yield

Then add the applicable costs:

Color cost per page = black CPP + cyan CPP + magenta CPP + yellow CPP

This produces a useful estimate for a page that consumes all four supplies. Black-only documents may use primarily black ink or toner, while photos and graphics can use substantially more color. For that reason, a single color CPP number cannot perfectly describe every type of print job.

If the printer uses a combined color cartridge, use that cartridge’s price and rated yield instead of calculating each color separately.

Example: calculating a full color estimate

Imagine a printer uses these supplies:

• Black cartridge: $40, rated for 1,000 pages
• Cyan cartridge: $35, rated for 700 pages
• Magenta cartridge: $35, rated for 700 pages
• Yellow cartridge: $35, rated for 700 pages

The estimated costs are:

• Black: $40 ÷ 1,000 = 4 cents per page
• Cyan: $35 ÷ 700 = 5 cents per page
• Magenta: $35 ÷ 700 = 5 cents per page
• Yellow: $35 ÷ 700 = 5 cents per page

The estimated combined color cost is 19 cents per page when all four supplies are included. This is an illustrative calculation, not a prediction for a specific printer or document type.

Include other replaceable printer parts

A cartridge-only calculation may not represent the printer’s full recurring consumables cost. Depending on the model, you may also need to account for:

• Drum or imaging unit
• Fuser
• Transfer belt or transfer roller
• Waste-toner container
• Printhead
• Maintenance box

Some printers combine several components into one cartridge. Others sell them separately. Check the printer’s manual and supply list to determine which parts apply and how often they are expected to be replaced.

To estimate a separate component’s cost per page, divide its price by its expected page life:

Replacement-part cost per page = part price ÷ expected page life

Then add that result to the ink or toner estimate. For example, if a $120 drum is expected to last 12,000 pages, its estimated cost is 1 cent per page. Add that cost to toner CPP if the drum is a separate replacement item.

Brother’s documentation and supply listings show why this distinction matters: some printer models use separately replaceable drum units. A toner-only estimate may therefore understate recurring consumables costs. See Brother’s toner and drum support information and the printer’s own documentation for model-specific details.

Consumables cost per page versus total cost per page

Be precise about what your calculation includes.

Consumables cost per page usually refers to ink, toner, and applicable replacement parts. It may exclude paper, electricity, service, subscription fees, and the printer itself.

A broader total-cost estimate can include:

• Printer purchase price
• Ink, toner, and other replaceable supplies
• Paper
• Electricity
• Service or repair costs
• Subscription fees

Add the costs you want to include, then divide by the number of pages printed during the selected period:

Total cost per page = total included costs ÷ total pages printed

State your assumptions clearly. A calculation that includes only toner should not be described as the printer’s total cost per page.

Why your actual cost may differ from the estimate

Rated yield gives you a consistent starting point, but real-world results vary. The number of pages a cartridge produces depends on factors such as:

• How much ink or toner each page uses
• Whether you print text, graphics, or photos
• Print quality and print mode
• How frequently the printer is used
• Inkjet maintenance routines or maintenance components
• Whether the printer uses separate drums or other parts

A lightly printed text page generally does not consume the same amount of supply as a full-page graphic or photo. HP notes that cartridge yield can vary with printed content, print mode, and frequency of use. Its page-yield guidance explains why a rated yield should be treated as an estimate.

ISO yield figures are useful because they create a common basis for comparing supplies. They are not a direct forecast of how many pages you will print with your particular mix of documents.

Inkjet and laser cost considerations

Inkjet printers

Inkjet costs can change significantly depending on what you print. Photos and graphics typically require more color ink than ordinary text documents, and printer maintenance may also affect ink consumption on some models.

If the printer uses an ink subscription or a tank-based system, compare the actual plan or bottle price with the amount of ink supplied and your expected print volume. Do not compare a subscription fee directly with a cartridge price unless the quantities, terms, and included supplies are equivalent.

Laser printers

Laser printers also rely on rated toner yields, so their advertised CPP is an estimate rather than a guarantee. Check whether the quoted toner yield includes the drum or whether the drum is sold separately.

For a more complete laser-printer estimate, add the per-page cost of any separately replaceable drum, fuser, transfer component, or waste-toner container that you expect to replace.

A simple cost-per-page worksheet

Use this worksheet to organize your calculation:

For color printing, include the supplies relevant to the type of page you are evaluating. For black-only documents, you may calculate a separate black-printing estimate. If you are comparing printers, use the same assumptions for each model, including cartridge size, yield basis, page type, and included components.

How to measure your personal cost more accurately

A yield-based estimate is useful before buying a printer, but you can also track your actual spending. Over a defined period, record:

1. The supplies you purchase.
2. The price paid for each supply.
3. The number of black-only and color pages printed.
4. Any separate replacement parts used.
5. Paper or other costs you want included.

Then divide the tracked costs by the pages printed. A longer measurement period usually provides a more useful result because a short period may end before a cartridge is fully used. Replacement timing, unused ink or toner, and unusually heavy print jobs can distort a brief calculation.

Common cost-per-page mistakes

Treating rated yield as a guarantee

A cartridge rated for 1,500 pages may not produce exactly 1,500 pages in your environment. Treat the figure as a standardized estimate.

Comparing cartridge prices without yields

A $30 cartridge is not automatically cheaper to use than a $45 cartridge. Divide each price by its rated yield before comparing them.

Ignoring separate supplies

A toner-only calculation can miss a separately replaceable drum, maintenance box, fuser, or other component.

Using black CPP for color pages

Color pages may consume black, cyan, magenta, and yellow supplies. Use a color calculation when evaluating color printing.

Assuming every page uses the same amount

Text pages, graphics, and photos can have very different coverage. Your document mix affects actual supply usage.

Mixing incompatible or unlike products

Confirm that each cartridge works with the exact printer model. Also make sure comparisons use compatible cartridge sizes, yield standards, print modes, and included components.

Forgetting paper and other costs

If you include paper, electricity, service, or subscription fees, say so. If you include only ink or toner, label the result as consumables cost per page.

The bottom line

To calculate a printer’s basic cost per page, divide the cartridge price by its rated page yield. For color printing, calculate the applicable black and color supplies separately and add them. For a more realistic estimate, include separate drums, maintenance parts, paper, subscriptions, or other costs that matter to your use.

The most useful result is not a single advertised number. It is a transparent estimate that identifies the cartridge, price, yield, document type, and costs included. That makes printer comparisons more honest—and gives you a better idea of what each page will actually cost.
