3D Print Cost Calculator

Work out the real cost of any print — and what to charge for it. Free, nothing to install.

Filament looks cheap until you add up energy, failed prints and your own time. Enter your numbers below to see the true cost of a print and a fair selling price. Everything updates instantly and stays in your browser.

Filament price (per kg) What you pay per 1kg spool Filament used (grams) From your slicer's estimate Print time (hours) Printer power (watts) ~100–150W average for most FDM printers Electricity price (per kWh) Failure rate (%) Buffer for failed/scrapped prints Your labor (minutes) Setup, removal, cleanup, post-processing Labor rate (per hour) Profit markup (%) Added on top of total cost to get your price

Costs are in whatever currency you enter — the math is currency-agnostic. Tip: most makers find labor and failures are the costs they forget, which is why prints feel unprofitable.

How the calculation works

Material = grams ÷ 1000 × filament price per kg.
Electricity = watts ÷ 1000 × hours × price per kWh.
Labor = minutes ÷ 60 × your hourly rate.
Failure buffer = a percentage of (material + energy + labor), because some prints fail and you still paid for them.
Suggested price = total cost × (1 + markup%).
