For people who sell 3D prints
Print Margin works out what a job actually costs you — filament, machine wear, electricity, your time, the prints that fail, postage, and the processing fee — then tells you what to charge to keep a real margin.
The problem
Most sellers price off grams of filament and a gut-feel multiplier. On a typical four-hour print, filament is about 13% of what the job really costs you. Your own time is closer to 70%.
Filament and purge waste, machine depreciation per hour, electricity, setup and post-processing time at your rate, consumables, and an allowance for the prints that fail — because a failed print spends real filament and real hours.
True cost per unit, the price you need to charge, your actual margin after the processing fee, and the effective hourly rate you are working for. That last number is usually the uncomfortable one.

One honest note: the arithmetic here is not a secret, and you could build it in a spreadsheet. What you are paying for is not having to — and for the profiles, history and branded quotes that make it part of how you sell.
Questions
Take a job you quoted last week and put it in. If the margin comes back where you expected, you have lost five minutes.
