Net Profit for eBay Sellers

Most eBay profit calculators ship a flat 13% and $0.35 per order and call it done. eBay's actual 2026 fee engine is not flat. The final-value fee varies by category from 3% to 15.3%. The per-order fee is tiered at $0.30 under $10 and $0.40 over. A Starter Store changes the math from a Basic+ Store. International payments add 1.65%. A flat-rate calculator is wrong before you click Save, and the first payout reconciliation proves it. Net Profit for eBay Sellers runs the real 2026 fee math, in your browser, on every keystroke. Two surfaces, one accurate engine. On the eBay sell form, a live badge below the price input shows your net profit and margin as you type. Item cost and shipping sit next to it. The badge is green at healthy margins, amber on thin ones, red when you are about to lose money. Pick the category on the form and the rate locks in. Toggle your Store tier inline. Add the international fee with one click. On Seller Hub Active Listings, a persistent Net Profit column appears on every row. It reads the prices of your own listings and computes profit against the defaults you set. Click any cell to override the cost and shipping for that one listing. Sort, filter, paginate, the column follows. What is free, what is Pro Free is the full live badge on the sell form, the accurate 2026 fee engine for every category and tier, up to 30 per-listing profit-column edits per day on Seller Hub, the per-order fee tier, the international toggle, and the Store tier controls. Free stays free. Pro unlocks unlimited per-listing edits on Seller Hub, multi-account Store-tier profiles, CSV export of the profit column, the category-fee override editor for sellers with negotiated rates, and a pinned breakdown tooltip that stays visible. Pro is part of a Zovo membership. Privacy and terms The extension reads only the price and category you typed yourself on the sell form, and the prices of your own listings on the Seller Hub grid. Zero scraping, zero catalog reads, zero API calls, zero account access. Your defaults and per-listing overrides stay in browser storage on your device.
