Enter your costs and a target margin — get the Etsy list price that hits that margin after Etsy takes its cut. Everything runs in this page; your numbers never leave your device.
PrintPrice is the complete offline pricing app ($9.99, one-time) with everything this free version leaves out:
Most sellers price backwards: they guess a price, then hope something is left after costs and fees. This calculator works the other way. It adds up your true unit cost (filament + electricity + labor), then solves for the list price where your take-home profit equals your target margin — after subtracting Etsy's $0.20 listing fee, 6.5% transaction fee, and 3% + $0.25 payment processing.
For the full method — including packaging, shipping, machine wear, batch runs, and the margin-vs-markup trap — read how to price 3D prints to sell on Etsy and the Etsy fee breakdown.
