For startups, the GMV metric is often one of the first performance indicators used to show traction. It reflects the scale of sales transactions, not profitability.
Expressed as a formula, GMV looks like this:
GMV = Sales price of goods × number of goods sold
So, if an eCommerce store sells 200 units at a sales price of $50 each, its GMV is $10,000. That’s the total value of sales transactions before accounting for shipping costs, marketing costs or transaction fees.
GMV vs. Revenue
GMV is related to revenue, but there’s a distinct difference: GMV is the total value of products sold. Revenue is what the company actually keeps after deducting fees and expenses.
- GMV: The gross transaction value of all sales.
- Revenue: GMV minus deductions like returns, shipping fees, marketing costs and transaction fees.
Take eBay as an example: its GMV reflects the total value of merchandise sold by users. But eBay’s net revenue comes from the fees it charges on those sales.
Shopify is similar: it processes billions in GMV for merchants, but its revenue comes from subscription fees and payment processing.
The difference is that GMV shows scale and revenue shows profitability. Together, they give you a good idea of your product-market fit.
Why Your GMV Metric Matters
Even with its limitations, GMV is a useful growth metric for startups and marketplaces.
- Early traction signal: A rising annual GMV shows growth over time and helps demonstrate demand before profitability is reached.
- Market share proxy: For marketplaces, GMV reflects the size and activity of the ecosystem.
- Comparisons across periods: Tracking GMV by month, quarter or year highlights growth trends.
Investors and finance teams often ask for GMV as a top-line performance indicator. But they will always want to see it paired with other KPIs like net revenue, gross margin, customer acquisition cost and customer lifetime value.
The Pitfalls of Overemphasizing GMV
Treating GMV as equivalent to revenue is a common mistake. It can inflate success and hide weak unit economics.
- Discount-driven GMV: Offering deep discounts or free shipping may boost GMV but simultaneously erode profitability.
- Returns and refunds: High return rates reduce the actual value retained.
- Marketing spend: Aggressive inbound marketing campaigns can drive GMV growth but lead to unsustainable customer acquisition costs.
GMV without context is a vanity metric. Pair it with profitability measures to avoid misleading yourself or investors.
How to Increase Gross Merchandise Value
Growing GMV isn’t achieved just by selling more merchandise. Increasing GMV means raising the total value of each sales transaction and encouraging repeat purchases.
- Raise average order value
- Use cross-selling and recommendation carousels to suggest complementary products.
- Create product bundles that encourage bulk buying.
- Shopify apps like Infinite Options let you offer personalized products, which can lift order values.
- Improve conversion
- Optimize the user experience with better search ranking, faster checkout and clear merchandising strategy.
- Test product bundles and volume discounts to encourage larger carts.
- Build loyalty and retention
- Launch a loyalty and rewards program to drive recurring revenue.
- Personalize the shopping experience with targeted offers and recommendation engines.
- Refine marketing
- Focus inbound marketing campaigns on high-intent buyers.
- Track KPIs like conversion rate and customer engagement to measure impact.
Tactics like free shipping, bundles and loyalty programs can lift GMV, but always weigh the trade-offs in margin and inventory costs.
GMV in Different Business Models
The GMV acronym applies differently depending on the business model.
- Marketplaces: For platforms like eBay, GMV is the core growth metric. Their revenue comes from transaction fees, not the merchandise itself.
- Direct eCommerce: For eCommerce brands that manufacture and sell their own products, GMV is gross sales before returns. Inventory costs and shipping fees are critical to profitability.
- Drop ship eCommerce: GMV reflects the total sales price, but profit is the margin between that price and what manufacturers charge.
- Channel-led hardware sales: GMV tracks the total value of products sold through retailers or distributors before channel discounts.
- SaaS metrics: GMV is less common, but SaaS companies track equivalents like monthly recurring revenue (MRR), annual recurring revenue (ARR) and total contract value. These are recurring revenue measures that function like GMV for subscription businesses.
Using Annual GMV as a Benchmark
Annual GMV is one of the clearest ways to show growth over time. Comparing year-over-year GMV highlights whether sales expansion is accelerating or slowing.
For example, a marketplace might report $50 million in annual GMV in year one and $120 million in year two. That growth metric signals strong adoption, but investors will still ask: what portion of that GMV translates into net revenue and profitability?
Always report GMV alongside revenue, gross margin and retention metrics.
When presenting GMV, transparency matters. Always show it in context with complementary metrics, such as:
- GMV: Total value of products sold.
- Net revenue: After fees, returns, and discounts.
- Gross margin: After inventory and shipping costs.
- CAC and LTV: To measure acquisition and retention efficiency.
- Cohort analysis: Segmented GMV by product line, geography, or customer type.
