What does this print actually cost you?

Filament, electricity, machine wear, failed prints and your time, in one number. Then a sale price that covers it.

Work out printer wear on the hourly rate page, Etsy fees on the Etsy pricing page, and your printer's watts on the printer power page. Values marked example are illustrative defaults; replace them with your own numbers.

How this is calculated

Filament = spool price ÷ spool grams × grams used.
Electricity = average watts ÷ 1,000 × print hours × rate. Use average draw, not the power supply's maximum rating: Bambu Lab lists the P1S at 1,000 W maximum (220 V) but about 105 W average when printing PLA.
Machine wear = (printer cost ÷ lifetime hours + maintenance per hour) × print hours.
Failures: material, electricity and wear are divided by (1 − failure rate), so the good prints carry the cost of the scrapped ones.
Labor = hands-on minutes ÷ 60 × hourly rate. Packaging is added as entered.
Suggested price = cost × (1 + markup) ÷ (1 − fees), so the markup survives marketplace fees.
