Gross Merchandise Value
Gross Merchandise Value (GMV) is the total value of all merchandise sold through a platform or marketplace over a specific period, before deducting fees, returns, and discounts. It represents the total scale of transactions facilitated.
Also known as: GMV, gross merchandise volume, total merchandise value
Formula
Sum of All Transaction Values
Why It Matters
GMV is the primary scale metric for marketplaces and platforms. While revenue measures what the platform earns (typically a percentage of GMV through fees), GMV measures the total economic activity the platform facilitates. This distinction matters because it captures the full value exchange happening on the platform.
For marketplace businesses, GMV growth indicates whether the platform is attracting more buyers, sellers, or higher-value transactions. Investors use GMV to evaluate marketplace scale and potential, though they increasingly scrutinize the relationship between GMV and actual revenue (the take rate).
However, GMV can be misleading if used in isolation. A marketplace could grow GMV by lowering take rates, offering unsustainable promotions, or including cancelled and returned orders. Always analyze GMV alongside net revenue, take rate, and net merchandise value (GMV minus returns and cancellations) for the complete picture.
How to Calculate
Sum the total sale price of all completed transactions on the platform during the period. Include the full transaction value, not just the platform fee or commission. Some businesses include shipping charges in GMV while others exclude them - choose a consistent approach. For the most accurate picture, also track Net Merchandise Value (GMV minus returns, refunds, and cancellations).

Industry Applications
A marketplace reports $50M quarterly GMV with a 15% take rate, generating $7.5M in actual revenue. After returns and cancellations (8% of GMV), net merchandise value is $46M.
Benchmark: Fast-growing marketplaces target 30-50% annual GMV growth; mature marketplaces target 15-25%
A SaaS app marketplace facilitates $10M in annual GMV across third-party integrations and add-ons, with a 20% take rate generating $2M in platform revenue.
How to Track in KISSmetrics
KISSmetrics can track GMV by capturing the full order value in purchase events across all sellers or product lines on your platform. Use custom properties to distinguish between marketplace revenue (your commission) and total GMV. Track GMV trends by seller, category, and geography to understand where platform growth is concentrated.
Common Mistakes
- -Treating GMV as revenue - for marketplace businesses, actual revenue is typically 5-30% of GMV depending on the take rate
- -Including cancelled orders, pending transactions, and returned items in GMV, which inflates the number
- -Using GMV as the primary growth metric without tracking the corresponding take rate and net revenue
- -Comparing GMV across platforms without understanding differences in category mix, return rates, and discounting practices
Pro Tips
- +Always report GMV alongside take rate and net revenue to give stakeholders the complete economic picture
- +Track Net Merchandise Value (GMV minus returns and cancellations) as a more accurate measure of actual economic activity
- +Analyze GMV per active seller and per active buyer to understand marketplace health beyond total volume
- +Use GMV cohort analysis to see whether newer buyer and seller cohorts are generating more or less economic activity over time

Revenue
Revenue is the total income generated by a business from the sale of goods or services before any expenses are deducted. It is the top line of an income statement and the starting point for all financial analysis.
Average Order Value
Average Order Value (AOV) is the average dollar amount spent each time a customer places an order. It is calculated by dividing total revenue by the number of orders in a given period.
Revenue Per Visitor
Revenue per visitor (RPV) is the average revenue generated for each visitor to your website. It combines conversion rate and average order value into a single metric that measures the total monetary value of your traffic.
Return Rate
Return rate is the percentage of sold items or orders that are returned by customers. It is a key indicator of product quality, accuracy of product descriptions, and customer satisfaction.
Refund Rate
Refund rate is the percentage of total transactions or revenue that results in a monetary refund to the customer. Unlike return rate which tracks physical product returns, refund rate measures the financial impact of all money-back transactions.
