What each field means
Inputs
- Filament used (g)
- The filament used used in the calculation, measured in g. Starts at 120 g so you have a working example on load.
- Spool cost ($)
- The spool cost used in the calculation, measured in $. Starts at 22 $ so you have a working example on load.
- Spool weight (g)
- The spool weight used in the calculation, measured in g. Starts at 1000 g so you have a working example on load.
- Print time (hr)
- The print time used in the calculation, measured in hr. Starts at 9 hr so you have a working example on load.
- Printer power draw (W)
- The printer power draw used in the calculation, measured in W. Starts at 120 W so you have a working example on load.
- Electricity rate ($/kWh)
- The electricity rate used in the calculation, measured in $/kWh. Starts at 0.16 $/kWh so you have a working example on load.
- Failure rate (%)
- The failure rate used in the calculation, measured in %. Starts at 8 % so you have a working example on load. Accepted range: 0–60 %.
- Markup (%)
- The markup used in the calculation, measured in %. Starts at 120 % so you have a working example on load.

FAQ
How does the 3d printing cost calculator work?
Price a print job properly: filament grams, print hours, power draw, failure rate, and a labor/markup layer.
What do I need to enter?
8 values: filament used, spool cost, spool weight, print time, printer power draw, electricity rate, failure rate, and markup. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the suggested price result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Estimates assume standard, average conditions — local rules, pricing, and materials vary.
Who is this tool for?
It's built for anyone doing everyday planning maths — a quick estimate that would otherwise need four browser tabs and a calculator app.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
