No usable source links are available for this idea. Its signal notes and scores need independent verification.
Solo makers selling handcrafted, electronics, and 3D-printed products From Scratch repeatedly sell at a loss because they cannot accurately calculate true costs. Beyond material costs, they overlook tool depreciation, electricity, 3D printer consumables, packaging and shipping, Platform fees, and labor (hourly rate equivalent) — unknowingly continuing to sell negative-margin products with implicit monthly losses of 300,000-800,000 KRW (~$225-$600).
Enter a product BOM to automatically calculate hidden costs beyond materials (tool depreciation, electricity, printer consumables, packaging/shipping, Platform fees, hourly labor costs) and receive true cost figures with recommended selling prices. Also provides break-even point analysis and margin simulations by order volume.
