GMV

GMV is the abbreviation for Gross Merchandise Volume, sometimes also called Gross Merchandise Value. It refers to the sum of all sales processed through a trading platform within a given period. If goods worth ten billion euros change hands via an online marketplace in one year, the GMV amounts to ten billion euros. It doesn’t matter who did the selling: the marketplace also counts the transactions of third-party merchants. What’s important is the difference to the platform’s own revenue. The marketplace usually keeps only a commission of a few percent, with the rest going to the sellers.

What the figure reveals about a platform – and what it doesn’t

For marketplaces, GMV is the most important growth metric. It shows how much trade actually flows through the platform. A company can have little revenue of its own and still boast a huge GMV. That’s exactly why young trading companies love this metric: it sounds impressively large.

For investors, this is a double-edged sword. A high GMV says nothing about profit. A platform can broker goods worth billions and still post losses. What matters is the so-called take rate, meaning the share of GMV that the platform keeps as its own revenue. If it stands at three percent, only 30 million euros of revenue remain from one billion in GMV.

Another catch: there’s no legally standardized definition. Every company decides for itself whether taxes, shipping costs, cancellations, or returns are included. Anyone comparing the figures of two companies is therefore often comparing apples to oranges. Reputable reports explain in the fine print exactly what’s included.

How gross merchandise value is calculated

The calculation itself is simple. You take every completed sale, multiply quantity by price, and add it all up. If a marketplace sells 1,000 headphones at 50 euros each in one day, that’s 50,000 euros in GMV. Whether the marketplace owns the headphones or merely brokers the sale doesn’t matter.

You can picture it like a weekly market. GMV is the value of all goods that cross the counter at every stall. The market operator only earns the stall fees from that. Anyone wanting to judge the operator’s success must look at the fees, not the merchants' revenues.

It gets more demanding when it comes to deductions. Customers send goods back, orders get cancelled, some payments fail. That’s why a distinction is often made between gross and net GMV. The net figure subtracts returns and cancellations and is therefore closer to the actual business. In fashion, the difference can be enormous, since a large share of orders there get returned.

Where the metric shows up in quarterly reports and headlines

Most commonly, GMV appears in the quarterly reports of major trading platforms. Amazon, Alibaba, Shopify, Etsy, or Zalando regularly cite the figure. Delivery services and ticket platforms use it too. Around shopping events like Singles Day or Black Friday, media almost always report on GMV records.

The term has also started appearing in connection with AI. Platforms justify investments in recommendation systems or automatic price adjustment by claiming they boost GMV. The logic behind this: better suggestions lead to more purchases, and more purchases increase the total. If GMV rises by just a few percent after such a change, that translates into billions for large providers.

A typical mistake is equating GMV with company revenue. Anyone reading a report about a GMV in the billions should always look for the actual revenue and profit. Only these three figures together give an honest picture of a platform’s condition.
