What it calculates: Gross Merchandise Value (GMV), Net Merchandise Value (NMV), Returns & Cancellations.
Gross merchandise value is units times price across everything ordered. It is not revenue: returns and cancellations come off it, and for a marketplace the seller keeps the goods value while the platform books only its commission.
A marketplace reporting GMV of a hundred crore may have revenue of five. Both numbers are true; only one of them pays salaries, and the gap is why GMV is the figure quoted in announcements and revenue is the figure in accounts.
Returns and cancellations are not marketing problems, they are arithmetic
Taking returns and cancellations off GMV gives net merchandise value — the goods that were actually bought and kept. In categories like apparel that deduction can exceed a third of the headline.
The calculator keeps the two rates separate because they behave differently. A cancellation costs you a sale; a return costs you the sale plus the shipping both ways and the handling, which is a strictly worse outcome.
Reverse mode solves the orders a net target requires
Planning usually starts from the net figure you need and asks what gross volume produces it. That is the direction reverse mode solves, and it is the one that stops a target being set without reference to the return rate behind it.
The gap is larger than people expect. At a combined 30% deduction, hitting a net target needs roughly 43% more gross orders, not 30% more — the arithmetic runs the other way.
It can be grown by doing unprofitable things
GMV rises with discounting, with subsidised shipping, and with any promotion that moves volume regardless of margin. A business can grow GMV steadily while losing more money on every order.
This is why it should never be read alone. Set it against contribution margin and the return rate, and it becomes a scale indicator rather than a performance claim.
Frequently Asked Questions
What is gross merchandise value?
GMV is the total value of goods sold over a period, calculated as units sold times average price. It measures sales volume on a marketplace or store but is not revenue, since the platform keeps only a commission of it.
How is GMV different from revenue?
GMV is the full transaction value flowing through the platform; revenue is what the business actually earns, often just a commission plus fees. A marketplace with high GMV can have far smaller revenue.
What is net merchandise value (NMV)?
NMV is GMV after deducting returns and cancellations. It reflects the value of goods that customers actually kept, giving a more realistic picture of effective sales volume than gross GMV.
Why do investors look at GMV?
GMV signals the scale of a marketplace and its growth trajectory. It is useful for comparing platforms, but it should always be read alongside take rate and revenue, since GMV alone says nothing about profitability.
Does GMV include discounts and taxes?
It depends on definition. Commonly GMV is measured at the price paid by customers. If you want a strict figure, decide whether discounts, shipping, and tax are included and apply that consistently.
Can a high GMV business still lose money?
Yes. GMV says nothing about costs. A platform can process huge GMV yet lose money if its take rate is thin and its acquisition and operating costs are high.

Tested both directions and round-tripped them: a net target solved back to gross orders must reproduce that net.
Tested that zero returns and cancellations makes net merchandise value equal gross, in both modes.
