Where Did My Profits Go? Deep Dive on Calculating Shopee, Lazada, and TikTok Shop Fees in 2026

Why Many Online Merchants Experience "High Sales but Low Cash Flow"

One of the most common complaints among online sellers in 2026 is, "Why am I packing orders non-stop, yet at the end of the month there is no cash left in the bank?" Some shops pull in six or seven figures in sales revenue, but their operational liquidity remains dangerously tight.

The primary culprit is usually not inventory mismanagement, but rather the failure to accurately calculate layered marketplace commissions, transaction fees, and campaign program costs. E-commerce giants like Shopee, Lazada, and TikTok Shop adjust their fee structures regularly. When you factor in store-funded discounts, vouchers, and advertising spend, platform deductions can easily eat up 15% to 25% of your gross sales. This article covers the different fee components, a step-by-step order calculation formula, and pricing strategies to protect your cash flow.

3 Major Fee Types Charged on Every Order

To compute your actual payouts accurately, you must understand the three core fee categories:

1. Payment Transaction Fees

This fee is charged by platforms to cover payment processing. It is calculated as a fixed percentage of the "gross customer payment" (which includes shipping costs paid by the customer and is calculated after customer-level voucher deductions). Rates vary depending on the payment method, such as credit card, PromptPay transfer, E-Wallet, or Cash on Delivery (COD).

2. Commission Fees

This is the standard fee for listing and selling on the platform. It is calculated as a percentage of the "listing price minus store-funded discounts" (excluding shipping fees). The percentage rates depend on the product category—fashion items, for instance, generally carry higher commission rates than consumer electronics or cameras.

3. Campaign and Marketing Program Fees

This is where many shops lose their margins without realizing it. These are optional fees charged when a shop signs up for promotional programs like Free Shipping Special, Coins Cashback, or targeted traffic boosts. The platform deducts a percentage from every eligible order, which can accumulate to an additional 5% to 10% of your gross sales.

The Hidden Cost: 7% Value Added Tax (VAT) on Fees

A crucial factor that online sellers often miss is the 7% VAT added to every single platform fee.

For example, if your commission fee is calculated as 100 Baht, the platform does not deduct exactly 100 Baht from your payout. Instead, they apply a 7% VAT, making the actual deduction 107 Baht. When building your pricing worksheets, always multiply estimated fees by 1.07 to match the real-world bank settlement statements.

Formula to Calculate True Net Profit per Order

To avoid selling at a loss during big campaigns, use this formula to calculate the net profit for each item:

Example Case Study:
You sell a fashion shirt for 300 Baht (product cost is 120 Baht, packaging cost is 10 Baht). The customer pays via credit card, and you participate in the Free Shipping Special program.
* Assume Category Commission = 5% (15 Baht)
* Transaction Processing = 3% (9 Baht)
* Free Shipping Program Fee = 5% (15 Baht)
* Pre-VAT Fees = 15 + 9 + 15 = 39 Baht
* Actual Deduction (including 7% VAT) = 39 x 1.07 = 41.73 Baht
* True Net Profit = 300 - 120 - 10 - 41.73 = 128.27 Baht (compared to the superficial estimate of 170 Baht before accounting for fees and VAT).

Pricing and Margin Protection Strategies

To safeguard your margins against fee inflation, consider these online retail strategies:

• Channel-Specific Pricing: You do not need to list the same price everywhere. If one platform charges higher fees, adjust your retail prices or reduce store coupons on that channel to offset the difference.
• Product Bundling: Grouping lower-priced items into bundles or multi-packs reduces the relative impact of transaction fees and shipping subsidies per unit, while boosting your Average Order Value (AOV).
• Strict Campaign Curation: Double-digit shopping days (like 11.11) often require deep store discounts. If your calculations show that joining will wipe out your margins, opt out or only submit high-margin SKUs.
• Claim VAT on Platform Fees: Platforms issue monthly electronic tax invoices for all deducted fees. Save these files! If your business is VAT-registered, you can claim these payments as input tax to offset your output VAT liabilities.

Conclusion

High sales volume alone does not ensure business survival. Understanding the fine print of platform fees and applying disciplined pricing math is the difference between a thriving store and a cash-strapped operation. Adjusting your retail strategy based on real net profit figures protects your cash flow and builds a resilient business.
