Marketplace commission calculation: what's really left from a Trendyol order?

The amount paid into your account for a product sold for 1.200 TL on a marketplace and the profit you keep are not the same thing. To calculate both correctly, you need a method more than a rate table.

In short

• Marketplace commission is calculated on the sale amount; on Trendyol the commission rate is applied VAT-inclusive, while some marketplaces quote it VAT-exclusive and add 20% VAT on top.
• Because the VAT on commission, shipping and service fee invoices is deductible, these charges enter the profit calculation at their VAT-exclusive amounts.
• Marketplaces withhold 1% e-commerce tax on the VAT-exclusive product sale price; it reduces the payout but isn't an expense, and is offset against your annual tax.
• The payout is the sale amount minus commission, shipping, service fee and withholding; order profit is the VAT-exclusive sale minus product cost and VAT-exclusive charges.
• On a marketplace using a VAT-inclusive rate, the break-even price is roughly 1.20 × (product cost + VAT-exclusive fixed charges) ÷ (1 − commission rate).

Most businesses selling on marketplaces see their revenue clearly but guess their profit. The "commission is fifteen percent, shipping is this much, the rest is ours" calculation usually comes out wrong, because it skips VAT, withholding and the tax inside the charges. That's why marketplace commission calculation is a question of method before it's a list of rates.

We don't give a current commission rate table here, because rates vary by category, seller and campaign period, and the only reliable source is your seller panel and your contract. Instead we calculate the payout and profit of an order step by step, then give the formula for the lowest price that avoids a loss.

Part 1 · Commission What is marketplace commission calculated on?

Marketplace commission is a brokerage fee charged at a set rate on the sale amount of the product sold. The rate depends on the product category; the same seller's products in different categories can carry different rates.

The most confusing point is whether the rate includes VAT. There are two practices:

Part 2 · Charges Which charges are there besides commission?

Commission isn't the only thing that reduces your payout. An order usually has these deductions:

• Shipping: if you use the marketplace's contracted carrier, the shipping fee is deducted from the payout. Some marketplaces charge a separate fee for low-value orders.
• Service fee: a platform fee, either fixed per order or a share of the sale.
• Campaign and advertising charges: campaigns you joined or advertising spend.
• E-commerce withholding: a 1% income or corporate tax deduction on the VAT-exclusive product sale price.

The marketplace invoices you for commission, shipping and service fees, and those invoices carry 20% VAT. Because you can deduct that VAT, the profit calculation uses these charges at their VAT-exclusive amounts. Withholding, on the other hand, isn't an expense; it's tax paid in advance on your behalf.

Part 3 · Worked example Trendyol commission calculation: one order step by step

In the example below we assume a product with 20% VAT is sold for 1.200 TL on a marketplace that uses a VAT-inclusive commission rate. The rates and amounts are only there to show the method.

The amounts are illustrative. Commission rates vary by category; take your own rate from your seller panel.

908 TL is the money paid into your account, not your profit. To find the profit, you also need to account for VAT and the cost of the product.

Withholding isn't booked as an expense; it's offset against annual tax. If you have per-order operating costs such as packaging or labour, deduct those too.

On this order, 21.5% of the VAT-exclusive sale is left as profit. If the same product goes into a campaign at 990 TL, the commission drops too, but shipping stays fixed and the margin melts quickly. So for each product, one number is enough: the break-even price.

Part 4 · Break-even How do you find the lowest price that avoids a loss?

The break-even price is the VAT-inclusive selling price at which an order makes neither profit nor loss. On a marketplace using a VAT-inclusive commission rate, for a product with 20% VAT, it's found with this formula:

Break-even price = 1.20 × (product cost + VAT-exclusive shipping + VAT-exclusive service fee) ÷ (1 − commission rate)

If your product's VAT rate isn't 20%, use your own rate instead of 1.20 (e.g. 1.10 for 10%). On marketplaces that quote commission VAT-exclusive, the commission's VAT is deducted separately; the rate in the formula is the VAT-exclusive rate.

If you want a target margin, say 15% of the VAT-exclusive sale, widen the denominator: 1,20 × 635 ÷ (1 − 0,15 − 0,15) ≈ 1.089 TL. If you're not sure your cost correctly includes waste, packaging and labour, start with calculating product cost; the other side of the price decision is in pricing strategy.

Part 5 · Checks Why does the payout differ from your calculation?

If the amount the marketplace pays doesn't match your calculation by more than a few kuruş, the reason is usually one of these:

What to check when there's a difference

• The product's category changed, or a different commission rate applied during a campaign.
• The order has a return or partial return, deducted as a reversal.
• Shipping was calculated differently because of volumetric weight or a low-value order rule.
• An advertising or campaign participation fee was deducted from the same payment.
• The payment covers several orders and sales on different dates.
• Withholding was assumed to be on the VAT-inclusive sale; the base is the VAT-exclusive amount.

We explain how payouts and invoices are corrected for orders with returns in the e-commerce returns process.

Part 6 · Heyşirket How does order profitability look in Heyşirket?

In Heyşirket's pre-accounting, every e-commerce order has a Mali özet (financial summary) section. It does the calculation above per order: sale amount (VAT included), sales VAT, net sale, product cost, commission, shipping, service fee, payment / POS fee, operating cost, Hakediş (net yatacak) (payout) and withholding, then pre-tax profit and net profit.

Step by step: turning on order profitability

1. Enter product costs

   Fill in Alış fiyatı (₺, KDV hariç) (purchase price, VAT-exclusive) on the product card. Products without a cost leave the profit calculation incomplete.

2. Define channel costs once

   In an order's financial summary, click Kanal maliyetlerini girin (enter channel costs). Enter Komisyon oranı (%) (commission rate), whether the rate is VAT-inclusive, shipping, service fee, operating cost and a provision for profit tax. This setting is used for all orders on that channel.

3. Compare estimates with actual amounts

   If the channel reported a charge with the order, that amount is used directly. If not, it's calculated from your settings and marked tahmini (estimated). On marketplaces, withholding is assumed at 1% even without a setting.

4. Match payouts to invoices

   On the Hakedişler (Payouts) screen, when a marketplace payment arrives the orders' invoices are marked as collected; commission, shipping and withholding are shown on separate lines. For Trendyol, payouts are pulled regularly from the current account statement (Cari Hesap Ekstresi).

Pre-accounting is included in the Profesyonel and Premium packages. How to set up the marketplace connection is in the marketplace connection guide; Trendyol-specific details are on the Trendyol integration and Hepsiburada integration pages.
