3D print cost calculator
Enter what your slicer tells you about a print and what your filament and electricity cost. The result updates while you type and shows where the money goes.
How the numbers are calculated
How is the filament cost calculated?
Filament used plus color-change waste, divided by the spool weight, times the spool price. An 85 g print with 30 g of waste from a 22.00 spool of 1000 g costs 115 / 1000 × 22.00 = 2.53.
How is the electricity cost calculated?
Print time in hours, times the printer's average power in kilowatts, times your price per kWh. Five hours at 120 W and 0.30 per kWh is 5 × 0.12 × 0.30 = 0.18. Use the average draw while printing, which is well below the power supply rating.
What is printer wear?
The printer's price spread over the hours you expect it to print before you replace it. A 600.00 printer that lasts 5000 hours costs 0.12 per print hour. It is a simple way to make each print pay for a share of the machine. Nozzles, belts and other spare parts are not included; add them to the printer price if you want them covered.
How do failed prints count?
The percentage you enter is added on top of filament, electricity and wear, because a failed print wastes all three. Your own time is counted once, not multiplied.
Which filament weight should I enter?
The weight your slicer shows after slicing, for everything on the plate including supports. If you came here from a tool page, the field holds the weight of the model printed completely solid; a normal print with infill is lighter, so replace it with the slicer's number.
