 How this estimate works
 
 Cost per gram = spool price ÷ spool net weight. Part cost = cost per gram × part weight. Enter the filament you expect to use, including purge and supports if you want those in the estimate. Results are rounded to the nearest paisa (₹0.01). 

 
 Example (editable defaults): ₹1,200 spool ÷ 1,000 g = ₹1.20/g. An 84 g part costs ₹100.80 in raw filament only — not electricity, labor, or selling price.
