The price you made up
Filament times two, plus a bit for time. It feels fair — until you count the kilowatt-hours, the nozzle, the failed print that burned six hours, and realise the order paid you less than minimum wage.
3D printing cost calculator
Filament is only part of what a print costs
The rest is electricity, machine wear, failed prints and your hours. Extruse counts every cent — for a hobby and for a business alike.

Three ways a print shop quietly loses money
The Etsy surprise
You priced it at 20. The marketplace took its cut, the payment processor took another, tax took a share of what was left. What reached your pocket was 12 — and you found out a month later.
The product that eats your printer
It has a beautiful margin, so you print more of it. Nobody tells you it occupies the machine for eight hours while a trinket earns the same in forty minutes. Your best product is starving the fleet.
How it works
From a file to a price you can quote — three steps
Move the numbers over from your slicer
01Filament weight and print time from PrusaSlicer, Bambu Studio or Orca. Type them in or paste the summary.
Set your rates once
02Labour, electricity, an allowance for failures and a minimum markup live in settings and apply to every new estimate.
Send an invoice, not a guess
03A PDF with the price, the print time and — only if you want it — the full cost breakdown.

What it does
A calculator that grew into a workshop
Material, electricity, machine depreciation, maintenance, failed prints, your labour, consumables and overhead. Failure is amortised properly — f/(1−f), not «plus ten percent».

Questions people actually ask
How accurate is print time from a model?
It is an estimate from volume, height and quality profile — and it is labelled as an estimate. A sliced file is always more accurate, so import G-code when you have it.
My printer is not on the list.
Add it on one screen: price, lifetime, watts and failure rate. The 63 presets exist so you can correct numbers rather than invent them.
Which currency and language?
Ten languages and any currency: English, Russian, German, French, Spanish, Portuguese, Polish, Italian, Norwegian and Chinese.
Does it work without the internet?
The app does, after the first sign-in. Three things need the network: that first sign-in, importing a model by link and updating the exchange rate. The site, like any site, opens online.
