Hey Product Hunt 👋
I'm Daris — I built PennyTurn because I kept losing track of what I was actually making reselling stuff. Fees, shipping, packaging all quietly eat into your sale price, and I got tired of doing the math by hand (or worse, not doing it at all and hoping for the best).
PennyTurn is a free, no-signup profit calculator for Vinted, eBay, and Depop sellers. Type in your buy price, sale price, and fees — it instantly shows your real profit, margin, and ROI. It also has a minimum-price calculator (set a target profit, get the exact price to list at) and a simple inventory tracker so you can see what's sitting too long.
Everything runs in your browser — no account, no ads, no data sent anywhere.
Would genuinely love your feedback: what's missing, what would make this more useful for how you actually resell? I'm actively building this out and want to build the right things next. 🙏
