3D Printing Cost Calculator

Custo3D is a free online calculator that helps you set the right price for your 3D printed parts. In a few seconds you add up filament, energy, labor, printer depreciation and profit margin to reach a fair, profitable sale price — right in your browser, no install, no sign-up.

How the 3D printing calculator works

Enter the print time, pick your printer (over 30 models from Bambu Lab, Creality, Prusa, Anycubic, Elegoo and Voron come pre-configured) and add the filaments used. The tool automatically calculates power consumption and depreciation, and you apply whatever margin and taxes you want. The result updates in real time as you adjust each value.

What goes into the cost of a 3D printed part

• Filament: grams used relative to the spool price.
• Energy: printer power consumption in kWh over the print time.
• Labor: preparation and post-processing time.
• Depreciation: printer wear spread over its lifespan.
• Margin and taxes: profit and taxes on the sale.

Why pricing correctly matters

Charging below the real cost is the most common mistake among people selling 3D prints. Accounting for every component — including energy and equipment wear — makes sure every part is profitable and your business is sustainable long term. With Custo3D you can compare scenarios, test different margins and find a competitive price for your niche.

Free, online and also on iPhone

The web version of Custo3D is completely free and works in any browser, on desktop or mobile, with no account required. For those who need more, the Custo3D iPhone app lets you save quotes, export to PDF and share links with customers, using the same precise calculation engine as the online version.

Frequently asked questions

How do I calculate the cost of a 3D printed part?

Add up the filament cost (grams used × spool price ÷ 1000), the energy cost (consumption in kWh × time × price per kWh), labor and printer depreciation. Then apply your desired profit margin on top of that subtotal.

What is the ideal profit margin for 3D printing?

There's no single rule, but margins between 20% and 40% are common. The calculator lets you freely adjust the margin to find the ideal price.

How do I calculate the filament cost?

Divide the weight used in grams by the total spool weight (usually 1,000g) and multiply by the spool price. Example: 50g of PLA from a $20 spool = 50 ÷ 1000 × 20 = $1.00.

What is printer depreciation?

It's the hourly cost that reflects printer wear over time. Divide the printer's price by the total estimated hours of use over its lifespan. The calculator already includes reference values for the most popular models.

Which printers are supported?

Over 30 popular models such as Bambu Lab, Creality, Prusa, Anycubic, Elegoo and Voron, with power consumption and depreciation pre-configured. You can also enter custom data for any printer.
