3D Print Cost Calculator
Before you sell a print (or quote a job), you need to know what it actually costs you. Enter your filament price, the model's weight and print time, and this free tool shows your material and energy cost per print, a failure buffer, and a suggested sale price at the margin you choose. No signup.
This estimates direct cost (filament + energy + a waste buffer + any labor you add). It doesn't include printer wear, nozzle/bed depreciation, or platform fees — add a little extra margin to cover those. Filament weight is the printed part's weight (your slicer reports it), not the spool.
How to read the result
Cost per print is the floor — sell below it and you lose money on every unit. Suggested price applies your chosen margin on top. For physical prints sold online, remember the platform takes a cut too, so bump the price a little more (model that with the Etsy fee calculator or Gumroad fee calculator).
Selling the design instead of the physical print? Then material and energy don't apply per sale at all — an STL file is "make once, sell many," so you price on usefulness, not grams. See how to price a digital product and where should I sell?
