GMV vs Revenue: What's the Difference (and Which to Track)

GMV vs revenue comes down to one distinction: what your store processed versus what it actually kept. Gross merchandise value (GMV) is the total dollar value of every order placed over a period, before returns, discounts, shipping, and platform fees are removed. Revenue is what you keep once those deductions land. On a lean direct-to-consumer brand the two sit close together; on a marketplace they can differ by 80% or more — and confusing them is one of the fastest ways to feel like you’re winning while your bank balance disagrees.

What Is GMV, and How Is It Calculated?

GMV, sometimes written gross merchandise volume, is the combined value of everything you sold before any costs come out. The formula is simple: multiply the selling price of each item by the number of units sold, then add it all up. Shopify defines GMV as “the total sales dollar value of goods sold over a specific period, before subtracting expenses like discounts, returns, and shipping costs”.

A quick illustration: sell 200 necklaces at $50 and 150 bracelets at $30, and your GMV is $14,500. Nothing about that figure tells you what you banked — it ignores the codes shoppers redeemed, the pieces that came back, the payment processing, and the cost of the goods themselves. That’s the whole nature of GMV: it measures gross demand and scale, not money kept.

GMV vs Revenue: Where the Two Numbers Split

The split comes down to deductions. GMV is booked the moment an order is placed; revenue is recognized only after returns, discounts, and fees are settled. Every cost that sits between “order placed” and “cash kept” widens the gap between the two.

Metric	What it measures	What’s removed
GMV	Total value of orders placed	Nothing — gross of all costs
Net revenue	Money recognized after settlements	Returns, discounts, allowances, platform fees
Contribution / profit	What’s left to run the business	Also removes COGS, shipping, payment and ad costs

For a marketplace, the gap is structural: the platform’s revenue is only its take rate — the slice of GMV it keeps. Amazon’s median referral fee is about 15% of the sale, and eBay averages roughly 12.9%, so $100,000 of GMV flowing across those platforms becomes only about $13,000–$15,000 of platform revenue. First Round Review uses eBay as the classic case: its GMV reflects everything users sell, while the company itself only ever earns the fees layered on top.

A Worked Example: What a $100,000 GMV Month Really Pays You

Here’s the gap in motion for a direct-to-consumer apparel brand. The dashboard shows a clean $100,000 GMV for the month. Watch what actually survives to net revenue:

Line item	Impact	Running total
GMV (1,000 orders placed)	—	$100,000
− Discounts & promo codes (~12%)	−$12,000	$88,000
− Returns & refunds (19% of orders)	−$16,720	$71,280
− Payment processing (~3%)	−$2,138	$69,142
= Net revenue		≈ $69,100

The store “did $100K,” but recognized about $69,100 — roughly 69 cents on every GMV dollar, and that’s before the cost of goods, shipping, and ad spend that decide actual profit. The discount line is conservative; coupon codes alone average around a 19% discount when shoppers redeem them. The returns line uses the economy-wide online return rate of 19.3% for 2025 — apparel usually runs higher. Nudge any of these levers and the “$100K month” quietly shrinks again.

Why GMV Flatters Your Dashboard

GMV rises for reasons that have nothing to do with a healthier business. Cut prices, and unit volume climbs while margin falls — GMV goes up anyway. Ship for free, absorb higher returns, or buy growth with unprofitable ad spend, and the top-line tile still looks great. Nationally, shoppers were expected to return nearly $850 billion of merchandise in 2025; every one of those dollars was counted in someone’s GMV first.

That’s why GMV is the number founders love to quote and lenders love to ignore. It’s also why so many teams fly blind: Shopify found that while 77% of merchants track total sales, fewer than half track profit margin. A rising GMV chart with no margin context can hide a business that’s getting bigger and less profitable at the same time.

Growth tactics can widen this trap or tighten it. A group-buying campaign — the model Farabiulder runs on Shopify — can lift both GMV and new-customer count at once, but it should still be judged on the net revenue and contribution margin it leaves behind, not the headline order value it generates.

Which Number Should You Actually Track?

Track both, but run the business on net revenue and contribution margin. GMV earns its place as a scale-and-demand signal: it tells you how much commercial activity you’re driving, and it’s useful for spotting trends, comparing channels, and sizing a market. What it can’t do is pay for inventory, salaries, or ads — only recognized revenue and the margin beneath it can do that.

A practical setup: report GMV at the top as a momentum indicator, then show net revenue and contribution margin directly underneath so nobody mistakes activity for profit. Pair those with your contribution margin and profit-margin benchmarks so every GMV figure has a “what we kept” number beside it. Before you celebrate the GMV a paid channel produced, run its orders through a CAC calculator to see what the growth actually cost.

The rule of thumb: GMV tells you how big you are; net revenue and margin tell you whether you get to stay that big. Put both on the dashboard, and never let the bigger, prettier number make the decisions the smaller, truer one should be making.
