When it comes to cross-border e-commerce, the biggest mistake is “assuming there’s a profit based on a hunch,” only to realize after six months that you’ve actually been operating at a loss the whole time. This article provides you with a comprehensive set of profit calculation formulas so you can run the numbers before you even get started.

I. The Complete Profit Formula

Net profit equals the selling price multiplied by (1 minus the platform commission rate), minus the cost of goods sold, inbound shipping costs, customs duties, FBL warehousing fees, and foreign exchange losses or payment processing fees.

Note that for cross-border stores, you must also subtract the VAT withheld by the platform (15% multiplied by the sales price)—this is something many beginners overlook.

II. Reference Data for Each Cost Item

Platform commissions range from 8% to 12% depending on the product category and can be found in the commission table in the seller dashboard. For cross-border stores, VAT is calculated as 15% multiplied by the sales price and is withheld by the platform; for domestic stores, VAT is deductible. Initial shipping (ocean freight) for small packages costs approximately 15 to 30 yuan per item, calculated based on volumetric weight. South African import duties vary significantly by product category, ranging from 0 to 45%; you’ll need to check the applicable rates for the relevant South African HS codes. FBL warehousing fees are approximately 0.1 to 0.3 rand per item per day, with additional charges for storage exceeding 90 days. Foreign exchange losses or payment processing fees range from 1% to 1.5%, calculated based on the exchange rates of Payoneer or FNB.

III. Real-World Case Study: A Breakdown of the Profit Margin for a Home Storage Box

The product is a plastic storage box with a purchase price of 18 yuan on 1688, weighing 500 grams and with a volume of 0.3 liters. The price in South Africa is set at 150 rand (approximately 57 yuan).

The cost breakdown is as follows: Purchase price of 18 yuan; initial ocean freight of approximately 8 yuan; South African customs duties calculated at 20% amount to approximately 11.4 yuan (150 rand multiplied by 20%, then multiplied by the exchange rate of 0.38); FBL fees of approximately 2 yuan; commission calculated at 10% amounts to approximately 5.7 yuan (150 rand multiplied by 10%, then multiplied by the exchange rate of 0.38), VAT for the cross-border store is 15%, approximately 8.55 yuan (150 rand multiplied by 15%, then multiplied by the exchange rate of 0.38), and the foreign exchange loss is approximately 1 yuan.

Net profit for domestic stores (excluding VAT withholding, deductible) is 57 minus 18 minus 8 minus 11.4 minus 2 minus 5.7 minus 1, which equals 10.9 yuan; the profit margin is approximately 19%. The net profit for the cross-border store (including 15% VAT withholding) is 57 minus 18 minus 8 minus 11.4 minus 2 minus 5.7 minus 8.55 minus 1, which equals 2.35 yuan, with a profit margin of approximately 4%.

This is why there’s such a huge gap in actual profitability between domestic and cross-border stores selling the same products—VAT alone eats up most of the profit.

IV. 5 Characteristics of High-Profit Products

First, the products are lightweight and compact—weighing less than 1 kilogram and with a volume of less than 1 liter—which reduces first-leg shipping costs and FBL warehousing fees. Second, they are subject to low tariff rates—below 20%—so it’s important to look up the HS code in advance to avoid categories with high tax rates. Third, products should have high pricing potential—over 200 rand—so that the absolute impact of commissions and VAT is minimal. Fourth, products should require no mandatory certifications or have low certification costs, thereby lowering the barriers to product selection and reducing compliance risks. Fifth, they should leverage the unique advantages of the Chinese supply chain, making them difficult for competitors to imitate and preventing prices from being driven down by cutthroat competition.
