FAQ
Frequently asked questions
How do I price 3D prints to make a profit?+
Add up all costs — filament, electricity, labour, packaging, platform fees — then apply a markup. Most successful sellers use 150–300% markup on total production cost. On Etsy, after fees and shipping, a 200% markup typically yields a 30–40% net margin. Use the free calculator to find your break-even first, then set a target margin and let LayerMath back-calculate the listing price.
Is it really free?+
Yes. The core calculator is free forever with no sign-up. You only pay if you want Pro features like inventory, SKU, Etsy sync and multi-material.
Do I need to create an account?+
Not for the free calculator. For Pro, you create an account so your spools, SKUs and history sync across devices.
Can I cancel anytime?+
Yes. Cancel from your account page and you keep Pro until the end of the billing period.
What currencies and taxes are supported?+
Supports £, $, €, CA$, A$. Handles UK/EU VAT, B2B reverse charge and US sales tax defaults.
