3D printing cost calculator
What will your filament print cost? Separate material and electricity, then multiply by the number of identical prints.
Your print and prices
The currency labels your prices; changing it does not convert amounts.
How the estimate works
Filament cost is used mass divided by spool mass, multiplied by spool price. Electrical energy is average watts multiplied by hours, divided by 1000; multiply by your price per kWh. Add both costs and multiply by the print count.
M = g ÷ G × P
E = W × h ÷ 1000
C = (M + E × T) × NFilament printing only. Include supports and purging in the entered mass if wanted. Use your own average power, not an assumed printer rating. Labour, wear, failed prints, delivery and other fees are not added. The estimate is not a selling price.

Virginia Cooperative Extension: estimating electrical energy use ↗Check the filled example
Chosen example: 50 g from a 1000 g spool costing 20 USD; 4 hours at an average 120 W; electricity 0.25 USD/kWh; 3 prints. Material is 1 USD and energy 0.48 kWh, costing 0.12 USD per print. One print: 1.12 USD; batch: 3.36 USD. These are illustrative inputs, not market prices or printer norms.
