A printer-hour uses electricity and a portion of the printer’s productive life. This calculator keeps those components separate. An expensive, faster printer may have a higher hourly rate but a lower order cost. Comparing hourly cost without total print time can therefore lead to the wrong decision.
Hourly energy cost = average watts / 1,000 × electricity tariff
Hourly depreciation = (purchase cost − residual value) / productive lifetime hours
Machine cost per hour = energy + depreciation + maintenance allowance
Worked example
A hypothetical printer costs 600, retains 100 in residual value and supplies 2,000 productive hours. Depreciation is 0.25 per hour. At 200 W average and a tariff of 0.30 per kWh, electricity adds 0.06. A maintenance allowance of 0.04 brings the economic machine rate to 0.35 per print hour, before filament and labour. Ten hours cost 3.50 on these assumptions.
Average power versus the label
Use average operating consumption measured across a representative print. A power-supply rating or a short heating peak is not the same thing. If you use a tariff that varies by time of day, enter an appropriate blended rate or compare separate scenarios. The site does not fetch utility tariffs.
Cash expense is not economic cost
Depreciation is an allocation of equipment value, not a fresh cash payment on every order. Including it can support replacement planning, but this model is not tax depreciation or an accounting policy. Maintenance should exclude any equipment cost already counted in purchase value to avoid double counting.
Do not infer machine capability
The calculator does not know printer specifications, product safety, dimensional tolerances or material compatibility. Its default printer numbers are examples, not manufacturer claims. Compare quotes only after checking that both production routes can actually deliver the required part.
