BEHIND THE NUMBERS

The math is part of the tool.

Cost = (g ÷ spool g × spool price) + (h × W ÷ 1000 × electricity rate) + (labor min ÷ 60 × labor rate) + (h × machine rate)

WORKED EXAMPLE

For 80 g from a 1,000 g spool priced at 25, a 4-hour print at 120 W and 0.20/kWh uses 2.00 of filament and 0.096 of electricity. Add 15 minutes of labor at 20/h and a 0.50/h machine allowance: total 9.096, shown as 9.10. Every money value uses your chosen currency.

HOW TO USE IT
  1. Copy total filament grams and print time from the slicer, including supports and purge.
  2. Enter your spool price, average power, electricity rate and optional machine allowance.
  3. Add hands-on labor, review each cost and export or print the estimate.
QUESTIONS FROM THE BENCH
Can you calculate cost from an STL?

No. An STL does not tell us your layer height, infill, supports, printer speed or waste. Use estimates from your slicer and update them from actual prints.

What belongs in machine allowance?

You can include an hourly allowance for maintenance, wear and equipment recovery. It is optional and does not include the separately entered electricity or labor.

Why use average watts?

A printer's power supply rating is a maximum capacity. Actual average draw varies with warm-up, temperatures, enclosure and printer; a power meter gives a more useful input.

Does this include tax or shipping?

No. Add taxes, packaging, delivery, marketplace fees and any other business costs separately before quoting a customer.

THE TOOLKIT / 01—03

Three tools. One honest estimate.

Start with one part, check your spool, then price a batch.
