Popular Questions
Common questions about pricing, profit, and selling online.
- Why should I calculate profit instead of revenue?
- Revenue is what the buyer pays; profit is what you actually keep after fees, materials, shipping, and ads. A shop can have strong revenue and almost no profit. Pricing and planning around profit is the only way to know whether your shop is sustainable.
- How much profit should I make per sale?
- It depends on your product and platform, but a healthy net margin for handmade and print-on-demand shops is usually 25–40% after fees and ads. For low-priced digital products, aim for at least $3–$5 of take-home profit per sale so the numbers still work after slow months and refunds.
- Why do so many sellers underprice products?
- The most common reason is pricing on materials alone and forgetting labor, fees, packaging, and shipping. Many sellers also copy competitors' prices — which often copies their underpricing too. Calculating your real costs first protects your margin from the start.
- Should I track conversion rate?
- Yes. Conversion rate — orders divided by visits — tells you whether your problem is traffic or your listings. If plenty of people visit but few buy, more traffic won't help; the fix is usually better photos, titles, pricing, or reviews. Most Etsy shops convert between 1% and 3%.
- Can these calculators be used for digital products?
- Yes. Digital products and printables still pay listing, transaction, and processing fees, so the profit and pricing tools apply directly — just set physical costs like shipping to zero. The Printable Pricing Calculator is designed specifically for digital downloads.
Seller Success Tips
Small habits that protect your margin and help your shop grow steadily.
Know your real profit
Always subtract fees, refunds, and ad spend before celebrating a sale.
Track conversion rate
More traffic isn't always the answer — fix the listing first if visitors don't buy.
Price for profit, not competitors
Copying a competitor's price often copies their underpricing mistake too.
Include hidden expenses
Packaging, postage, listing fees, and software add up fast — budget for them.
Review pricing regularly
Costs and platform fees change. Re-check your prices every few months.
Set realistic income goals
Base targets on profit per sale, not sticker price, so the goal stays reachable.
