How to use this calculator
- Enter the filament used (g) and the spool price ($/kg).
- Optionally add printer power (W), print time (hours) and your electricity rate to include power cost.
- Add a markup % for wear, failures and your time, then read the total.
How it works
The 3D Print Cost Calculator adds up the real cost of a print: filament, electricity and an optional markup.
Material cost = grams ÷ 1000 × price per kg. Electricity = printer power ÷ 1000 × hours × rate. The markup is applied to the subtotal to cover failed prints, machine wear and your labour.
Worked example
25 g print, $25/kg, 120 W, 4 h, $0.30/kWh. Material $0.63 + electricity $0.14 = $0.77 before any markup.
Frequently asked questions
Should I include electricity?
It's usually small (a few cents per print) but it adds up over long jobs and many prints. Leave the power fields blank to ignore it.
What markup should I use?
If you sell prints, a markup covers failed prints, machine wear, maintenance and your time — many makers use anywhere from 50% to several times the material cost.
