Are You Really Making Money on Trendyol? Channel-Based P&L Guide 2026

The "Seller Trap" on Trendyol: Revenue ≠ Profit

Many Trendyol sellers make a critical error: they confuse gross revenue with actual income. When you look at your Trendyol seller panel and see "Sales: 500,000 TRY," this number is highly misleading. After deducting commissions, shipping costs, return losses and advertising expenses, the real profit may be just 50,000 TRY — or even a loss.

According to MercanWorks OÜ's analyses, the average Trendyol seller loses 20–35% of gross revenue to hidden costs. Here is how to calculate these costs correctly.

Trendyol Commission Rates by Category (2026)

Category	Commission Rate	Impact on 100 TRY Sale
Fashion / Clothing	18–25%	18–25 TRY commission
Electronics	8–12%	8–12 TRY commission
Home & Living	12–18%	12–18 TRY commission
Personal Care	15–22%	15–22 TRY commission

Full P&L Calculation: Step by Step

Let's say your product sells for 200 TRY on Trendyol and the product cost is 80 TRY.

Example Calculation: Fashion Product

Sale Price	200 TRY
Product Cost	−80 TRY
Trendyol Commission (20%)	−40 TRY
Shipping Cost	−25 TRY
Return Provision (15% rate)	−12 TRY
Ad Spend (10% of revenue)	−20 TRY

Net Profit: 200 − 80 − 40 − 25 − 12 − 20 = 23 TRY
Net margin: 11.5%. While gross margin appears 60%, true net margin is only 11.5%.

Electronics Product: Different Cost Structure

Sale Price	1,000 TRY
Product Cost	−650 TRY
Trendyol Commission (10%)	−100 TRY
Shipping Cost	−30 TRY
Return Provision (5% rate)	−18 TRY
Ad Spend (5% of revenue)	−50 TRY

Net Profit: 1,000 − 650 − 100 − 30 − 18 − 50 = 152 TRY
Net margin: 15.2%. Lower commission rate, lower return rate — healthier unit economics.

5 Metrics Every Trendyol Seller Must Track

• Commission Rate by Category: Verify your actual Trendyol commission — it may differ from what you expect
• Return Rate by SKU: Some products have 30%+ return rates destroying all profit
• Shipping Cost per Order: Dimensional weight and carrier rates directly impact margin
• ROAS (Return on Ad Spend): Trendyol Ads ROAS below 3x is usually unsustainable
• Net Margin by Channel: Compare Trendyol vs Hepsiburada vs own website profitability

Return Rate: The Silent Profit Killer

Return rates in fashion can reach 20–30%. Each return means: outbound shipping cost + return shipping cost + product inspection + potential quality reduction. For a product with 11.5% net margin, even a 15% return rate can eliminate all profit.

MercanWorks OÜ recommends tracking return rate by SKU monthly and discontinuing or repricing any product with return rate above 20%.
