Profit Calculator PRO Profit Calculator PRO is a Chrome extension that helps online sellers quickly understand the real profit of each sale. Enter your brutto (VAT‑included) sale price, VAT rate, and your costs (amount or %), and the extension calculates: - Net profit (after VAT and all costs) - Profit margin (% of brutto sale) - A detailed per‑cost expense breakdown You can also save profiles for different marketplaces (e.g. eBay, Amazon, Etsy) so your usual fees and VAT are just one click away. Key features: - Net profit & margin Enter brutto sale and VAT once See exact net profit and profit margin for each item - Flexible cost model Add any number of cost rows (item cost, marketplace commission, ads, shipping, other fees…) Each cost can be an Amount or a % Choose when each cost applies: - Before VAT (percent of brutto sale) - After VAT (percent of net revenue) - After selected costs (percent of a base you define) - After all other costs A “Select base costs” dialog lets you precisely control the base for “After selected costs”. - Per‑cost breakdown After each calculation, see how much each cost contributed as a net expense Makes it easy to see which fees hurt your profit the most - Marketplace profiles Save/load profiles for different marketplaces or account types (e.g. “eBay DE”, “Amazon UK”) Profiles store: - VAT rate - All cost rows (names, values, amount/% and when applies) - Base‑cost selections for “After selected costs” Switching profiles is one click, with a confirmation if there are unsaved changes. - Autosave of current state Your last entered sale, VAT, and costs are automatically saved as a draft Closing and reopening the popup does not reset the fields How the calculation works: - VAT is extracted from the brutto sale only: netRevenueAfterVAT = bruttoSale / (1 + VAT%) - For costs with Type = Amount, the value is used as‑is (VAT‑neutral). - For costs with Type = %, the percent base depends on When applies: Before VAT → base = bruttoSale After VAT → base = netRevenueAfterVAT After selected costs → base = netRevenueAfterVAT - selectedBaseCosts After all other costs → base = netRevenueAfterVAT - allOtherCosts - Finally: Net profit = netRevenueAfterVAT - sum(all cost expenses) Profit margin = netProfit / bruttoSale * 100 - Example Suppose you have: Brutto sale: €90 VAT: 19% Item cost: €30 (Amount, Before VAT) Ads: 5% of sale (Percent, Before VAT) Marketplace commission: 16% of sale (Percent, Before VAT) Shipping: €7 (Amount, Before VAT or After VAT – it stays €7) The extension will: - Extract VAT from €90 to find net revenue. - Compute each cost as a net expense from the correct base. - Show net profit, profit margin, and a per‑cost table so you can see exactly how much Ads, commission, shipping, and item cost each contribute.
