FAQ

Questions sellers
actually ask

Etsy charges a 6.5% transaction fee on the sale price, plus a 3% + $0.25 payment processing fee, plus a $0.20 listing fee per item sold. On a $25 sale with a $2 listing fee amortized, that's roughly $2.62 in fees — before your product cost. Use HelpSeller to see the exact breakdown for your price.
A healthy margin is 25–40% after all fees and product costs. Below 15% is considered risky — especially for physical products with unpredictable shipping and packaging costs. Digital products typically achieve higher margins (40–70%) because cost of goods is near zero. HelpSeller shows your margin in real time and flags when it's too low.
It depends entirely on your price, cost, and fees. On a $25 digital product with $2 cost and standard Etsy fees, your net profit is roughly $16/sale — meaning you'd need about 125 sales/month. At $35 with the same cost, you'd need ~85 sales. The HelpSeller Goal Tracker calculates your exact number based on your real setup.
Yes. Enter Amazon's referral fee (usually 8–15% depending on category) as the platform fee, and add FBA fulfillment fees as part of your product cost. The Fee Builder lets you configure any combination of percentage and fixed fees to match your exact Amazon cost structure.

Yes. The Scenarios module lets you set up to 3 price points — for example Conservative ($20), Current ($25), and Premium ($35) — and compare profit, margin, and fees side by side. The winner is highlighted automatically. It's the fastest way to make a pricing decision with confidence.
