💰 Why it matters

Knowing filament cost = knowing your margin. Most makers underprice by 30–50% because they forget waste + electricity + finishing time.

⚡ Beyond filament

Real cost = filament + electricity (~₱5/hr) + machine depreciation (~₱3/hr) + your time. Filament is 30–60% of true cost.

🎯 Pricing rule

Selling? Standard maker formula: (material × 3) + setup fee. Or use our instant quote tool.

How we calculate it

effective_weight = print_weight × (1 + waste%) cost_per_print = (effective_weight / spool_weight) × spool_price prints_per_spool = floor(spool_weight / effective_weight)
