Poshmark Profit Calculator Chrome extension security report

See your real Poshmark profit — fee, payout, margin & ROI — right on the listing page. Free, private, no login. See exactly what you'll take home on every Poshmark sale — before you list, before you accept an offer. Poshmark's fees are simple in theory ($2.95 flat under $15, 20% at $15+) but easy to get wrong when you're juggling cost of goods, negotiated offers, and bundles. This calculator does the math for you, right on the page. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Open any Poshmark listing and a profit card appears automatically between the price and the description. No clicks, no setup — it's just there. ✦ REAL FEE MATH Automatically applies the correct Poshmark fee tier ($2.95 flat under $15, or 20% at $15 and up) based on the price you enter. ✦ BUILT FOR OFFERS, NOT JUST LISTING PRICE Poshmark sales rarely close at the listed price — buyers negotiate. Enter the price you'd actually accept and see your real fee, payout, and profit for that number, not the sticker price. ✦ BUNDLE-AWARE Poshmark charges one fee per bundle, not one per item. Toggle "This is a bundle," enter the bundle total and combined cost, and get the correct one-time fee calculation — most calculators get this wrong. ✦ COST OF GOODS MEMORY Enter what you paid once, and it's remembered for that specific listing next time you open it. ✦ MARGIN & ROI AT A GLANCE See profit margin % and ROI % alongside the dollar amounts, so you can spot your best (and worst) listings fast. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ - Poshmark resellers who flip clothing, shoes, and accessories - Thrift flippers checking margins before they buy inventory - Anyone tired of doing fee math in their head or a separate spreadsheet ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY, FIRST ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ - All calculations happen locally in your browser - No account, no login, no sign-up - No data is ever sent anywhere — the extension makes zero network requests - Your cost-of-goods entries are stored only in your browser's local storage - No ads, no analytics, no tracking ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ FREE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Completely free, no premium tier. If it saves you time, a review helps other resellers find it.
