3D Print Cost Calculator
Estimate the cost of a 3D print from filament used, filament price, print time, printer power and machine wear — plus a selling price with markup.
How to use
- 1Enter the filament used (grams, from your slicer) and the spool price.
- 2Enter the print time, printer wattage, electricity price and optional wear cost and markup.
How it's calculated
Cost = grams × price per kg ÷ 1000 + hours × watts ÷ 1000 × price per kWh + hours × wear per hour. Price = cost × (1 + markup).
Frequently asked questions
Where do I get the filament weight?
Your slicer (Cura, PrusaSlicer, Bambu Studio) shows the estimated grams and print time after slicing.
What should wear cost include?
Printer depreciation plus parts like nozzles, belts and build plates — often $0.10–0.50 per hour for hobby printers.
How do I price prints for sale?
Add failed-print allowance, your time for setup and post-processing, then a markup for profit.
