Reference excerpt

Gross merchandise volume (alternatively gross merchandise value/GMV or gross merchandise sales/GMS) is a term used in online retailing to indicate a total sales monetary-value (e.g. in U.S. dollars or Euros) for merchandise sold through a particular marketplace over a certain time frame. GMV includes any fees or other deductions which a seller might calculate separately. Site revenue comes from fees and is different from the monetary-value of items sold. GMV for e-commerce retail companies means the average sale price per item charged to the customer multiplied by the number of items sold. For example, if a company sells 10 books at $100, the GMV is $1,000. This is also considered as "gross revenue". In this case, the business model is based on a retail model, where the company basically purchases the items, maintains inventory (if need be) and finally, sells or delivers the items to customers. It does not tell the net sales as GMV does not include costs involved and returns of products.

Worked examples

Example 1 — a first encounter with Gross merchandise volume

Start with the simplest possible case. Write down what Gross merchandise volume claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gross merchandise volume before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gross merchandise volume ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gross merchandise volume

In research: Gross merchandise volume appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Gross merchandise volume in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Gross merchandise volume is common in secondary-school and first-year university syllabi. It links to neighbouring topics E-commerce, Online retailers, Revenue, so understanding it makes those chapters shorter.
In everyday life: Look for Gross merchandise volume outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
