Gross Merchandise Value (GMV), also known as gross merchandise value or gross trading volume, refers to the total value of all goods and services sold via an e-commerce platform, an online shop or a marketplace within a specific period. This metric measures the total transaction volume before deduction of costs, commissions, discounts, returns or cancellations. GMV is one of the key performance indicators in e-commerce, and particularly in the marketplace business, because it reflects the sheer scale of the business conducted via a platform, regardless of how much of this remains as revenue for the platform operator.
How GMV is calculated
The basic formula is simple: GMV is calculated by multiplying the number of units sold by the average selling price over a defined period.
| Measure | Meaning |
|---|---|
| Units sold | Number of products or services sold during the period |
| Average selling price | Average price per unit (Average Selling Price) |
| GMV | Units sold × average selling price |
A simple real-life example: If an online shop sells 20,000 items in a quarter at an average selling price of 75 euros, the GMV is 1,500,000 euros. At first glance, this figure does not indicate how profitable the shop is, but merely how high the trading volume was.
It is important to define the period and scope precisely. Some platforms report GMV inclusive of delivery costs and taxes, whilst others exclude them. Some exclude returns and cancellations (Net GMV), whilst others do not (Gross GMV). When comparing GMV figures from different sources, it is therefore always important to check exactly what has been included.
GMV is not the same as revenue
The most common misinterpretation is equating GMV with revenue. This is particularly misleading in the case of marketplaces. On a marketplace, many third-party sellers trade via the platform. The GMV then comprises the total value of all these sales, whilst the platform operator’s revenue only includes commissions, fees and its own sales – in other words, a fraction of the GMV.
- GMV: Total value of all transactions processed via the platform.
- Revenue: The proceeds that actually remain with the platform operator, such as commissions, fees, advertising revenue and sales of its own goods.
- Net revenue / profit: Revenue minus all costs.
A marketplace with a GMV of one billion euros may have platform revenue in the low three-figure million range, depending on the commission rate. Anyone who confuses GMV with revenue massively overestimates a platform’s economic power. This is precisely why GMV is a popular, yet also a metric that must be interpreted with caution in investor presentations and growth reports.
GMV as the basis for calculating licence fees
In the context of e-commerce platforms, GMV has a second, very practical meaning: it serves as the basis for calculating licence fees. Instead of a flat-rate licence fee, some providers link their prices to the trading volume processed via the shop, as this roughly correlates with the size and performance of the business.
Example: Adobe Commerce
Adobe Commerce charges based on turnover or GMV. Adobe does not publish an official price list; industry estimates suggest starting prices of around 22,000 US dollars per year for the on-premises version, which increase as GMV rises. For retailers, this means that as business grows, the licence fee increases accordingly, making platform costs a variable that scales with success.
Example: Shopware
Shopware also uses GMV as a threshold. The Community Edition is open source and can be used free of charge up to a GMV of 1 million euros per year; above that, a paid plan is required. Here, therefore, GMV does not serve as a continuous multiplier, but as a threshold beyond which a paid plan applies. This difference in usage – in one case as a running factor, in the other as a threshold – highlights how important it is to read the specific licensing model carefully.
Why GMV is important despite its limitations
Despite the risk of misinterpretation, GMV is a meaningful metric when viewed in the right context. It shows the growth in trading volume over time, allows for a comparison of the market sizes of different platforms, and is a useful indicator of a marketplace’s reach. However, when assessing economic health, GMV must always be considered alongside turnover, the take rate (the proportion of GMV that the platform collects as revenue) and profitability.
Real-world example: GMV in platform valuation
Major marketplaces such as Amazon or Alibaba regularly report GMV figures in their annual reports, as these impressively demonstrate the scale of their trading ecosystem. The definition of Gross Merchandise Volume is largely understood in the same way across the industry, even if the exact scope (including or excluding taxes, including or excluding returns) varies between companies. For a small or medium-sized business calculating the licence costs of a platform such as Adobe Commerce, its own GMV is the decisive input factor, as it directly determines the level of the licence tier.
GMV in the context of platform selection
For decision-makers in e-commerce, GMV is relevant for two reasons. Firstly, as a key performance indicator for their own growth; secondly, as a cost driver in GMV-dependent licensing models. Anyone making a platform decision should calculate the expected GMV trajectory for the next three to five years: for a rapidly growing online shop, a GMV-linked model can become significantly more expensive over time than a model with predictable licence costs that are decoupled from turnover. It is precisely this calculation that is a common reason why retailers consider switching platforms. Anyone who does not know their own GMV, or can only estimate it roughly, cannot properly assess the true costs of a GMV-linked model; this is why accurate tracking of trading volume is the first step in any platform and budget decision.
Take rate: the lever between GMV and turnover
If you want to interpret GMV correctly, you cannot ignore the take rate. The take rate describes the proportion of GMV that a platform retains as its own revenue, typically via commissions, fees and advertising revenue. If a marketplace’s GMV is 500 million euros and the take rate is 12 per cent, this results in platform revenue of around 60 million euros. The take rate is therefore the key factor that explains why two platforms with identical GMV can generate completely different revenues. A low take rate can be a deliberate growth strategy to attract merchants, but it can also indicate fierce competition. When assessing a business model, the combination of GMV and take rate is therefore significantly more meaningful than GMV alone.
Interpreting GMV growth correctly
Over time, GMV growth is a frequently cited measure of success, but it can be misleading. A sharp rise in GMV accompanied by a falling take rate or increasing subsidies (such as high discounts or free delivery) does not automatically indicate a healthy business. One-off effects also distort the picture: a single major customer, a seasonal outlier or the inclusion of newly acquired shops can cause GMV to surge without a corresponding growth in operational performance. Reliable analyses therefore examine GMV over several periods, adjust for one-off effects and compare it with key figures such as order volume, average order value and repeat purchase rate. Only this overall picture reveals whether genuine economic development underlies the growth in volume.
GMV in the total cost of ownership calculation
For a retailer weighing up different platforms, GMV is not just a reporting metric, but a direct cost factor. With a GMV-linked model such as Adobe Commerce, the licence fee rises in line with trading volume, which requires an honest assessment of the total cost of ownership. The following list shows which figures should be included in this calculation:
- Expected GMV trajectory over three to five years, including realistic growth assumptions.
- Licence model: ongoing GMV-based pricing (Adobe Commerce) or a fixed threshold (Shopware from 1 million euros GMV).
- Operating costs for hosting, development, extensions and maintenance, which are incurred regardless of GMV.
- Switchover costs, should the model become uneconomical as GMV rises.
This is precisely where GMV transforms from an abstract metric into a concrete basis for decision-making: a shop that is growing rapidly may, in the long term, find a GMV-linked model more expensive than predictable licence costs, and this difference can economically justify a switch to a different platform.
GMV, AOV and conversion rate in combination
GMV never stands alone, but arises from the interplay of several operational metrics. Three of these are particularly closely linked to it. The average order value (AOV) indicates how much a customer spends per order; the conversion rate measures the proportion of shop visitors who actually make a purchase; and traffic describes the total number of visitors. Put simply, GMV can be understood as the product of traffic, conversion rate and average order value over a given period. This is more than just an academic breakdown: it shows which levers a retailer can pull to increase GMV. More qualified traffic, a better conversion rate through an optimised checkout process, and a higher average order value through cross-selling and upselling all have a direct impact on sales volume. This breakdown is relevant when choosing a platform because a modern, fast and high-converting shop system contributes directly to GMV via a better conversion rate, thereby also influencing the GMV-dependent licence costs. This closes the loop between technical platform quality, trading volume and the cost model.
Frequently asked questions about Gross Merchandise Value
What is the difference between GMV and turnover?
GMV is the total value of all goods sold via a platform. Turnover is the revenue that actually remains with the platform operator (commissions, fees, own sales). On marketplaces, turnover is only a fraction of the GMV.
How is GMV calculated?
GMV = number of units sold × average selling price over a given period. Depending on the definition, this may be before or after returns, taxes and delivery costs.
Why do e-commerce platforms use GMV for pricing?
Because GMV roughly correlates with the size and performance of a business. Adobe Commerce continuously links its licence fees to GMV, whilst Shopware uses 1 million euros in GMV as the threshold for paid plans.
Does a high GMV equate to high profit?
No. A high GMV indicates a high trading volume, but says nothing about margins or profitability. GMV must always be considered alongside turnover and profit.
What does Net GMV mean?
Net GMV is the gross merchandise value after deducting returns, cancellations and refunds. Gross GMV does not exclude these items.
