Work out 3d print cost instantly with clear inputs, formula shown and shareable results.
Filament cost is grams used times the spool price divided by a thousand, and machine cost is the print time times an hourly rate covering power, wear and depreciation. On long prints the machine hours often exceed the filament cost, which is why quoting by weight alone undercharges for tall thin parts.
Material cost
cost = grams x spool price / 1000
Total cost
total = material cost + print hours x hourly machine rate
cost = grams x spool price / 1000. Filament cost is grams used times the spool price divided by a thousand, and machine cost is the print time times an hourly rate covering power, wear and depreciation.

Enter filament used, price of a 1 kg spool, print time, machine and power cost per hour. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
