3D printing helper calculators
Estimate remaining filament, a practical machine hourly rate and the selling price required for a target margin. Calculations run only in your browser.
FILAMENT
Filament length and part yield
Convert spool weight to theoretical length and estimate how many parts the remaining material can produce.
Estimated remaining length0 m
MACHINE RATE
Printer hourly machine cost
Turn purchase cost, useful print hours and maintenance into an internal hourly rate for quoting.
Hourly machine-cost baseline$0 / h
MARGIN PRICE
Target-margin selling price
Work backward from total cost, target gross margin, selling fees and a tax allowance.
Required selling price$0
Scope: Filament length assumes uniform diameter and the density entered. The machine rate is a quoting baseline, not an accounting depreciation schedule. Verify all taxes and marketplace charges for your own location and sales channel.
