Amazon to eBay profit calculator: what one sale would leave

The check reads the Amazon page and eBay’s search once, as a buyer in the US sees them. The same product within a day shows the saved result.

• Amazon price and stockThe buy box price and the stock line on the product’s page. A price Amazon shows only in the cart is not read, so that product gets no break-even.
• Similar eBay listingseBay’s Buy It Now search for the first ten words of the Amazon title, its first 40 results. A listing counts when most words of the shorter of the two titles appear in the other, and it names no other size, count or colour. A title cannot tell every size or model apart, so open the five cheapest, linked with their shipping, before you trust their price.
• Break-even on eBayThe lowest sold price, with the shipping the buyer pays, that leaves $0.00 after the costs below. Below it, every sale loses money.
• For 15% profitThe price that leaves 15% of the Amazon cost with tax, after every cost, to the nearest cent.
• The costseBay’s fee as 15% of the sale: its selling fees page charges 13.6% in most categories, so 15% sits above it; books, movies and music pay 15.3%. $0.40 per order, which eBay lowers to $0.30 on orders of $10 or less. 9% sales tax on the Amazon price; the real rate depends on the delivery address. eBay counts its fee on the total the buyer pays, sales tax included, so the fee on the buyer’s tax is a line of its own. No ad fee.

• How fast it sellsThe search shows what similar listings ask, not what sold. Count sold and active listings in the sell-through rate calculator.
• Whether a listing is the same productTitles can match while the size, pack or model differs. Open the five listings before you trust the lowest price.
• Tomorrow’s pricesAmazon and eBay prices change through the day. A result is the moment of its check; check again the next day.

eBay’s dropshipping policy does not allow buying the item on Amazon to ship to your buyer. In eBay’s words, “listing an item on eBay and then purchasing the item from another retailer or marketplace that ships directly to your customer is not allowed on eBay.” It allows orders sent directly from a wholesale supplier. The guide to eBay’s dropshipping rules explains what that means.

Checking by hand works for a few products. In Productivo, Product Scanner searches eBay by keyword or category for items that sell, finds the same product on Amazon and works out the profit at your own pricing. You add the matches you want to Products, and their prices and stock follow Amazon inside your profit rules.
