GMV is $1,400,000 and net revenue is $994,000, 71% of it. GMV includes shipping the customer paid, orders later returned and the value of discounts, none of which are revenue, which is why it is the number people quote and never the number they bank.

How the Gross Merchandise Value Calculator works

GMV includes shipping the customer paid, orders later returned and the value of discounts, none of which are revenue. It is the number people quote and never the number they bank, and the gap is usually a third or more.

What GMV counts and what it does not

Gross merchandise value is the total value of goods sold through a channel before any deductions. No fees removed, no refunds netted off, no discounts necessarily applied depending on how it is defined.

It is a marketplace metric by origin, used to describe the size of a platform rather than the health of a business. eBay reports GMV because eBay's revenue is a small percentage of it; the number describes the market it operates.

For an individual seller it is a scale measure and nothing more. GMV says how much moved through the channel; it says nothing about what you kept, and the two can diverge enormously between channels with different fee structures.

The gap between GMV and revenue

For a seller, revenue is GMV minus refunds, minus discounts if they were not already deducted, and minus any amounts collected on behalf of others such as marketplace-facilitated sales tax.

Net revenue then subtracts the marketplace fees, which on some platforms is 15% or more, and on others is a good deal less. Two sellers with identical GMV on different platforms can have net revenues differing by 20%.

Which is why GMV is a poor basis for comparing channels. A channel with high GMV and a 20% fee load, high return rates and heavy discounting can contribute less than one with half the GMV and none of those. Comparing channels on GMV is the most common analytical error in multichannel selling.

Why it still gets quoted

GMV is the largest number available, which is most of the reason it appears in pitch decks and press releases. It grows faster than revenue during expansion and it does not go down when margins compress.

It is genuinely useful for a small set of purposes: measuring channel scale, negotiating with suppliers on volume, and comparing your own growth period on period within a single channel where the fee structure is constant.

It is misleading for valuation, for profitability comparison and for deciding where to invest. Businesses acquired on GMV multiples have been repriced sharply when the buyer got to the contribution, which is a well-documented pattern in aggregator acquisitions.

The multichannel version

Aggregating GMV across channels is straightforward and needs one discipline: consistent definitions. If one channel's figure includes shipping revenue and another's does not, the total is meaningless.

Decide once whether GMV includes shipping charged to the customer, whether it is before or after discounts, and whether cancelled orders are excluded. Then apply it everywhere. Most reporting inconsistencies in multichannel businesses come from different platforms defining these differently by default and nobody normalising.

The more useful aggregate is contribution by channel, which requires the same discipline plus a fee and cost allocation. It is more work and it is the only version that answers where to put the next pound of effort.

Take rate, and reading it from the other side

Take rate is the platform's revenue as a percentage of GMV, and understanding it tells you what a marketplace actually costs. A platform with a 15% take rate keeps 15p of every pound that flows through it.

Calculating your own effective take rate by channel is a useful exercise, and the answer is often higher than the headline fee. Referral fee, fulfilment fee, storage, advertising, and the discount required to be competitive on the platform all belong in it.

Sellers who do this frequently find their effective take rate on a major marketplace is 30% to 40% once advertising is included, against a headline referral fee of 15%. That is the number to use when comparing against a direct channel, and it changes the conclusion in a lot of cases.

Where to go next

The Gross Merchandise Value question rarely arrives on its own. These are the ones that usually come with it:

Net Revenue Calculator — Shipping margin made visible.
Operating Cash Flow Calculator — Profitable but broke, quantified.
Refund Impact on Profit Calculator — Ad spend is wasted on refunded orders too.
Etsy Fee Calculator — Every Etsy fee on one sale, itemised.

Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price, check the platform's current fee schedule before you price a product against it. This is not tax or business advice.

Frequently asked questions

What is gross merchandise value?

The total value of orders placed, before returns, discounts, fees and often before tax. It measures marketplace activity rather than business performance.

Why do businesses quote GMV?

Because it is the largest number available. For marketplaces it is genuinely the right measure of platform scale; for a retailer it mostly obscures what the business earns.

How far is GMV from net revenue?

Commonly 60% to 80% of GMV survives to net revenue after returns, discounts and fees. The exact figure depends entirely on category and channel.

Which should I report?

Net revenue for the business, GMV only where the audience genuinely needs a measure of gross activity. Reporting GMV alone is a choice to be judged on a number nobody receives.
