Printer Ink Cost Calculator

The printer is not the purchase. The ink is the purchase, and the printer is the delivery mechanism, which is why a $60 inkjet can cost more over three years than a $250 tank machine.

Cost per page is the number that exposes it.

Core formulas:

Cost per Page = Cartridge Price / Cartridge Page Yield

Monthly Ink Cost = Pages Printed per Month × Cost per Page

Annual Ink Cost = Monthly Cost × 12

Total Annual Cost = Annual Ink + Annual Paper + Printer Amortization

Page yield: the number of pages a cartridge is rated for, measured under the ISO/IEC 24711 and 24712 standards at 5% page coverage. Five percent is a sparse business letter with a lot of white space, so it is a best case rather than an average. Heavy graphics or full-page photos can cut real yield by half or more, and a cartridge that promises 300 pages may deliver 120 if you print photos with it.

Rough cost per page by printer technology

Approximate, and the spread within each category is wide. Use them to see which class of machine you are in, not as a price list.

Worked example: Your printer’s black cartridge costs $28.99 and yields 450 pages. Color cartridge set costs $42.99 and yields 300 pages. You print 60 pages/month (80% black, 20% color).

• B&W CPP = $28.99 / 450 = $0.064/page
• Color CPP = $42.99 / 300 = $0.143/page
• Monthly cost = (48 × $0.064) + (12 × $0.143) = $3.07 + $1.72 = $4.79/month
• Annual ink cost = $57.48/year

The calculator carries full precision rather than the rounded cents above, so it reports $4.81 a month. That is rounding, not disagreement.

Sixty pages a month is light use, and at that volume a cartridge printer is the right machine. The arithmetic turns against it fast as the page count climbs.

What actually saves money

• Draft mode. The single biggest lever, and free. Internal documents do not need photo-quality black.
• Duplex printing. Halves the paper line without touching the ink.
• Third-party and remanufactured cartridges cost far less. Quality varies a lot by brand, and some printers now reject non-original chips after a firmware update, which is worth checking before you buy six.
• Ink subscriptions such as HP Instant Ink or Epson ReadyPrint can win at moderate volumes. Work out your own cost per page first, because these are priced per page printed rather than per page of ink used, and a month where you print nothing still bills you.
• An ink tank printer once you are printing regularly. The machine costs a few hundred more and the ink costs almost nothing, so the payback depends entirely on volume: around 300 pages a month it repays itself inside a year, at 100 pages a month it takes closer to three. Put what one costs in your shop into the optional field above and the calculator works out your own crossover. It does not guess the price, because a printer price frozen into a web page is out of date within a year and means nothing outside one country.

Do not leave an inkjet idle. The most expensive pages most households print are the ones lost to cleaning cycles. An inkjet that sits unused for weeks will purge ink to clear its own nozzles, and a printer used twice a year can empty a cartridge without printing anything at all. If you print rarely, a mono laser is the better machine: toner does not dry out.
