The 5% that changes your trade.
Calculate the margin you actually keep after a sale.
Work backwards from the sale
EA’s published Ultimate Team guide describes a 5% transaction fee on the sale price. Our calculator uses that rate: sale price × 0.95 gives proceeds; subtract your purchase price to find estimated profit.
A worked example
Buy for 10,000 coins and sell for 12,000: the fee is 600, proceeds are 11,400, and profit is 1,400. That is a 14% return on your purchase. Break-even is purchase price ÷ 0.95. Actual listings must also fit the item’s price range and EA’s permitted price steps.
