What does that 3D print actually cost you?
Six free calculators for filament, machine time, power and pricing. Every formula is printed on the page, and nothing you type leaves your browser.
Filament cost calculator
Enter the numbers from your own receipt and slicer.
The defaults above are the calculator's own example values — a $22 spool of 1000 g, a 45 g model and a 12% waste rate. Replace every one of them with your own figures. Figures from the defaults, not market data.
All calculators
Six tools, grouped by the question you are trying to answer. Start with filament cost — it is the number every other calculator builds on.
How these calculators are built
Four rules that decide what is on every page. They are the reason the numbers here can be checked instead of trusted.
The formula is printed on the page
Each calculator shows the arithmetic it uses, in plain text, directly above the result. If a figure looks wrong you can work out why without filing a support ticket.
Defaults are labelled as assumptions
A $22 spool and a 12% waste rate are plausible starting examples, not market averages we claim to have measured. Filament prices, tariffs and platform fees move, so anything you did not type yourself is an example.
Nothing is uploaded
The arithmetic runs in your browser. There is no account, no server round trip and no analytics on the input fields. You can open a calculator, disconnect from the network and still use it.
Sources instead of invented numbers
Where a figure depends on a supplier, a utility tariff or a marketplace fee, the page says so and points you at the official source rather than guessing a number and presenting it as fact.
Popular calculators
The three groups people ask for most, and the guides that explain the assumptions behind them.
What these calculators are not
They are arithmetic with editable inputs, not a market price list. Every default is a starting assumption you are expected to overwrite with your own receipt, your own electricity tariff and your own slicer estimate. Treat any figure you did not enter yourself as an example.
