Marketplace fees, true profit, pricing, shipping, customs, inventory and listings — type your question and get a straight answer in seconds. The full detailed report costs less than a cup of coffee: $2.95.
The number that matters is not what the buyer pays but what lands in your account after everyone else takes their cut. On a typical marketplace sale, three hands reach into your price: the platform's transaction or final-value fee, the payment processor's percentage plus a fixed fee, and your own cost of goods and shipping. Sellers who only watch gross revenue routinely discover they are moving serious volume at single-digit margins — or actual losses. This calculator walks your real sale through every deduction and shows the net profit and honest margin percentage, with a plain-spoken verdict on whether the item is worth keeping at that price.
The price tag is not the profit. Enter your sale price, product cost, shipping and the platform's fee percentages — this calculator shows the fees, the real net and your honest margin per sale.
Because shipping is a real cost whether you charge the buyer for it or bury it in the price. If you list 'free shipping' at a higher price, the buyer paid it; if you absorb it, you did. Either way it belongs in the profit calculation.
After fees and shipping, most solo sellers need 30-50% gross margin to cover their own time, packaging mistakes, returns and the occasional ad. Under 20% is living dangerously — one return or dispute can erase the profit from several sales.
Often yes — eBay and Etsy calculate their percentage on the total the buyer pays including shipping. That is exactly why this calculator treats the full paid price as the base for fees.
