1Set your location — In Settings, pick your state (or tap Detect). Sales tax and the average electricity price fill in automatically. You can override either one.
2Quick — One item, printed one or many times on a plate. Add a row per filament/color, enter the whole plate's grams and print time from your slicer, and how many copies are on the plate. You get the price per item.
3Full Calc — Full breakdown with hardware and packaging. With one part it works like the original advanced calculator. Add more parts for different items on the same plate. Shared plate costs (filament, power, machine wear, plate cleanup) are split across parts by weight if every part has grams, otherwise evenly per piece. Hardware and packaging can apply to all parts or just one.
4Fees & tax — Card processing, marketplace, and per-item event fees are built into the price so your margin holds after fees. Choose whether your sticker price includes tax (common at events) or tax is added at checkout.
5Profiles — Save your printers (wattage, cost, lifespan) and filaments (spool price & size). Star one of each as the default.
6Bulk & Saved — Send any item's cost to Bulk to build a quantity discount table. Save prints to this browser and back up everything as a JSON file.
💡 Margin math: margin = profit ÷ pre-tax price. With fees built in: Price = (Cost + fixed fees) ÷ (1 − Margin − fee% × (1 + tax)). Fee % is charged on what the customer pays, including tax. Rounding applies to the sticker price; profit is recalculated from the rounded price. Tax and power rates are statewide averages (Tax Foundation July 2026, EIA July 2026) — check your exact local rate before filing.
