How is Gross Merchandise Value Calculated?
Gross Merchandise Value is a key performance indicator used in e-commerce and online marketplaces. Here, we'll look at how to calculate Gross Merchandise Value:
- Simple formula for GMV calculation: The calculation of Gross Merchandise Value (GMV) is straightforward and follows the formula: GMV = Total Sales Price x Number of Units Sold. This formula provides the total value of goods sold through an online marketplace or e-commerce platform, serving as a key metric to assess a company’s overall sales performance.
- Example GMV Calculation: For example, if an online store sells 500 units of a product priced at $20 each, the GMV would be calculated as follows: GMV = $20 x 500 = $10,000. Similarly, for multiple products with varying prices and sales numbers, GMV is determined by summing up the total sales values for each product, offering a comprehensive view of performance.
- Clarification: It’s important to note that GMV does not account for factors such as discounts, shipping fees, or returned items. GMV is calculated before accrued expenses are deducted. Accrued expenses usually include marketing, returns, delivery costs, and discounts. This means that GMV represents the gross figure before any deductions, making it a top-line metric that focuses on the sales volume rather than profits.
Why is Gross Merchandise Value Important?
Now that we've explained how to calculate GMV, we'll look at three reasons why Gross Merchandise Value is important:
- Role of GMV in measuring business performance for e-commerce companies: Gross Merchandise Value (GMV) serves as an insightful metric for e-commerce businesses to gauge their overall performance. By calculating the total value of goods sold over a specific period, GMV provides insights into the sales volume and transactional activity on a platform. This metric is especially useful for marketplaces and online retailers, where the gross volume of sales reflects the scale and effectiveness of their operations.
- How GMV helps in tracking growth trends and market presence: Tracking GMV over time allows businesses to identify growth trends and better understand their market presence. An upward trajectory in GMV suggests increasing customer demand, expanded product offerings, or improved marketing strategies. By analyzing shifts or patterns in GMV, businesses can gain insight into their competitiveness.
- Its use as a key indicator for investors and stakeholders: For investors and stakeholders, GMV is a useful indicator of a company’s growth potential and market position. Although GMV alone doesn't account for profits or costs, it provides a top-line view of sales activity and customer engagement. Combined with other financial metrics, GMV helps stakeholders evaluate the overall health and scalability of an e-commerce business, making it a factor in investment decisions.
Limitations of Gross Merchandise Value as a Metric:
Like any metric used to help management or investors understand a business, gross merchandise value has it's limitations. It's just as important to understand what GMV is as it is to understand what it is not. Here are three limitations of GMV as a metric:
- Does not account for profitability or operating costs: Gross Merchandise Value focuses solely on the total value of transactions over a given period, ignoring the underlying costs associated with generating those transactions. As previously discussed, expenses such as marketing, fulfillment, and operational costs are not factored into GMV, meaning two businesses with identical GMV figures could have vastly different levels of profitability. This omission can give a skewed impression of a company's financial health if used in isolation.
- Can sometimes be misleading as a standalone metric: GMV emphasizes gross sales volume rather than the quality of those sales. A higher GMV doesn’t necessarily translate to sustainable or loyal customers, as it could be driven by deep discounts, flash sales, or other short-term strategies. These tactics can inflate GMV figures temporarily while potentially eroding overall business value. This makes GMV an incomplete metric when measuring long-term success.
- Importance of using GMV in combination with other key performance indicators (KPIs): To gain a comprehensive understanding of business performance, GMV should be analyzed alongside other indicators like net profit, Customer Acquisition Cost (CAC), and Customer Lifetime Value (LTV). These additional metrics provide context to GMV, revealing how well a company converts sales into profitability and supports sustainable growth. When paired with these KPIs, GMV becomes a more actionable figure for decision-making.
Comparison with Other Metrics:
Now that we've seen some limitations of GMV as a metric, we'll compare it to some other ways that e-commerce businesses typically measure performance.
Gross Merchandise Value represents the total value of goods sold through a marketplace or platform without deducting any fees, returns, or other costs. On the other hand, Revenue refers to the income a company actually earns, typically after deducting discounts, refunds, and fees. Net Sales further refine this by accounting for returns and allowances, giving a clearer picture of productive sales. Gross Profit narrows the focus even more by subtracting the cost of goods sold (COGS) from Net Sales, highlighting the profitability of sales activities. While GMV offers a high-level view of overall sales activity, it does not provide insights into revenue retention or profitability.
GMV is particularly useful for businesses operating in e-commerce or marketplaces when they want to measure their market size or overall transactional volume. It’s an effective metric for gauging growth trends, especially for platforms at an early stage or those focused on scaling. However, relying solely on GMV can be misleading for evaluating financial health, where metrics like Revenue, Net Sales, and Gross Profit provide a more accurate view of actual earnings and efficiency. Businesses should use GMV to understand aggregate user activity and platform engagement but turn to other metrics for insights into profitability and operational success.
