With the values above, starting from the VAT-inclusive price, what remains as each cost is deducted:
The VAT inside the price the customer pays is not your income. Profit is calculated on the VAT-exclusive sale amount; enter product cost, shipping and service fees excluding VAT too, so both sides use the same basis.
n11's commission varies by category. If you also sell the same product on Trendyol, enter each channel's rate separately; the difference between channels usually comes from commission and service fees.
On top of category commission, n11 charges a marketing service fee and a marketplace service fee on the sale amount. Because they are percentages, their amount rises with the price while their effect on the margin stays the same.
For low-basket products, shipping is the cost that cuts the margin most: 45 TRY of shipping on a 300 TRY sale excluding VAT is 15 points on its own.
A returned order is more than a cancelled sale; it leaves round-trip shipping and packaging costs. Multiplying that cost by your return rate and spreading it over every sale brings the margin closer to reality.
