Businesses and individuals often underestimate the true cost of printing. It's not just about the price of the ink or toner; several factors contribute to the overall expense of each printed page. This calculator helps you break down these costs, providing a clear understanding of your printing expenditure.
What goes into your cost per page?
Several components make up the cost of a single printed page:
Ink/Toner: The most obvious cost. The price of the cartridge divided by the estimated yield (pages it can print) gives you a per-page cost for the consumable.
Paper: The cost of the paper stock used for printing.
Printer Depreciation: The printer itself is an asset that loses value over time. This cost is spread across the estimated pages the printer will print in its lifetime.
Maintenance/Repairs: Costs associated with keeping the printer operational, including servicing and parts replacement.
Power Consumption: The electricity used by the printer while it's active and in standby.
Consumables (other than ink/toner): This can include items like drums, fusers, or waste toner boxes, depending on the printer type.
How to Use the Calculator
To accurately calculate your cost per page, you'll need to gather some information about your printer and its consumables. Enter the following details into the calculator below:
