Hi Product Hunt! 👋 I'm the maker of TrueMargin.
I built this tool to scratch my own itch. I run e-commerce and print-on-demand campaigns, and I realized that my Facebook ROAS dashboard was lying to me. By the time I factored in Shopify/Stripe gateway fees, dynamic ad spend, and a 2% return rate, my actual profit was hovering near zero.
Spreadsheets got too annoying to update on the fly, so I coded this lightweight calculator to instantly show me my true margin and break-even CPA before I scale a product.
It's completely free, requires no login, and works great on mobile. I'd love to hear your feedback on what other metrics you'd like to see added!
