Stop guessing what a sale will earn. Marginary turns marketplace fees and real costs into clear projected profit—privately, even offline.
Know what you keep before you list.
Marginary is a private profit calculator and decision journal for individual marketplace sellers. Enter a selling price, shipping, tax, item cost, packaging, labor, ads, and other expenses to see projected take-home, fees, profit, and margin instantly.
Built-in eBay and Etsy fee profiles show included charges, exclusions, and source links so an estimate never hides its assumptions. Create a custom profile when your category differs.
