What it means
GMV became a standard metric because marketplaces do not own the goods they help sell. When a platform connects a buyer and an independent seller, the money changing hands is far larger than anything the platform can recognise as its own income, so GMV captures the scale of the ecosystem while revenue captures the platform's cut.
The relationship between the two is the take rate, which is platform revenue divided by GMV. A marketplace with a 12% take rate keeps twelve cents of every dollar transacted, and small changes in that percentage move revenue dramatically at scale.
Investors watch GMV growth and take rate together, because GMV growing while take rate falls can mean the platform is buying volume with discounts. GMV is deliberately gross, which is both its strength and its weakness.
It is usually quoted before deducting returns, cancellations, discounts, delivery charges and failed payments, so a headline figure can overstate real economic activity by a meaningful margin. Serious analysts look for net GMV, which strips those out, or at least for disclosure of the return rate.
It is also easy to inflate. Adding a low-margin category with high ticket prices, entering a market with heavy promotional subsidies, or counting gift card purchases and their later redemption can all push GMV up without improving the business.
A platform reporting only GMV growth, with no accompanying revenue or contribution figures, deserves a sceptical read. Used properly, GMV is a good operating metric for the teams inside the business.
It breaks cleanly into orders multiplied by average order value, and each of those breaks further into buyers, purchase frequency, basket size and price, giving product and marketing teams levers they can actually pull.
In practice
Real-world examples
Example 1
A food delivery platform reports quarterly GMV of $420,000,000 while its own revenue is $63,000,000, a 15% take rate covering commission and delivery fees. The gap surprises new investors who assumed the larger figure was the company's income.
Example 2
A ticketing marketplace runs a promotion that cuts buyer fees to zero for a month. GMV climbs 18% but revenue falls, which tells management the volume was bought rather than earned.
Example 3
A business-to-business parts marketplace tracks GMV per active buyer rather than total GMV, because a handful of large industrial accounts would otherwise mask a decline in the long tail of small workshops.
Think of it
Gross Merchandise Value is like the total cash collected at a weekend car boot sale gate. It shows how much money changed hands between buyers and sellers, but the venue owner only gets to keep the small pitch fees charged at the entrance.
Formula
Calculation
GMV = Number of orders x Average order value. Platform revenue = GMV x Take rate. Net GMV = GMV - Returns, cancellations and discounts.
Consider an online marketplace for handmade homeware that processes 180,000 orders in a quarter at an average order value of $65. GMV is 180,000 x $65 = $11,700,000.
The platform charges sellers a 12% commission, so platform revenue is $11,700,000 x 12% = $1,404,000. Returns and cancellations run at 8% of GMV, which is $11,700,000 x 8% = $936,000, giving net GMV of $11,700,000 - $936,000 = $10,764,000. Because commission is refunded on returned items, the revenue that actually sticks is closer to $10,764,000 x 12% = $1,291,680, roughly $112,000 less than the headline number implied.Case study
Seen in the real world
The following case is illustrative and the company is fictional. Kettleford Market, an invented marketplace for refurbished electronics, told its board that GMV had grown 47% year on year, from $60,000,000 to $88,000,000, and treated that as the headline achievement of the year.
A closer look told a more complicated story. Take rate had fallen from 11% to 8.5% because the platform had cut commission to attract larger refurbishers, so revenue grew only from $6,600,000 to $7,480,000, about 13%. Returns had also risen from 6% to 11% of GMV as the mix shifted towards older devices, meaning roughly $9,680,000 of the reported GMV never actually stayed sold.
In this illustrative example the board asked management to report net GMV, take rate and contribution per order alongside the headline number from the following quarter. The immediate effect was uncomfortable, but it redirected the marketing budget away from the categories that generated impressive GMV and poor economics.
Watch out
Common mistakes
- Treating GMV as revenue. Only the take rate portion belongs to the platform, and reporting GMV as income overstates the business by a wide margin.
- Quoting GMV without the return rate. A platform with an 11% return rate is running a materially smaller business than the headline suggests.
- Celebrating GMV growth driven by subsidies or discounts. Volume bought with promotional spend disappears when the promotion ends.
Questions
People also ask
Does GMV include shipping and taxes?
Definitions vary by company, which is exactly why the basis of preparation should be stated; most platforms include the item price and exclude taxes, but treatment of delivery charges differs.
Is GMV a recognised accounting measure?
No, it sits outside standard accounting frameworks, so there is no enforced definition and comparisons between platforms need care.
When is GMV genuinely useful?
When it is paired with take rate, net GMV and contribution per order, it is a good indicator of ecosystem scale and of whether a marketplace is becoming more or less central to its category.
