Every POD seller eventually hits the same wall: you're making sales, but when you add up the Etsy listing fee, the 6.5% transaction fee, the payment processing fee, the print-on-demand base cost, and maybe some ad spend — the "profit" is a lot lower than expected. Or negative.
The problem isn't the fees themselves. It's that they're spread across three different dashboards, change depending on which provider and channel you use, and interact in ways that aren't obvious until you do the math by hand.
So we did the math. We built a calculator. Then we built a fee breakdown tool. Then a break-even planner. Then a seasonal upload calendar, because another problem is missing holidays because you didn't know you needed to upload 6 weeks in advance.
We built 8 tools, consolidated them into one place, made them entirely browser-based (no data leaves your device), and launched PODMargin as a free resource for the POD community.
PODMargin is a product of TSN Studio, a small indie software team. We also build Chayaani.com and other tools for creators and makers. Got feedback or ideas? We read every message.
