Shipped Volume

Shipped Volume is a core operational and financial metric used by Amazon to measure customer demand and product sell-through.
It shows how many individual units have been shipped (not just ordered or received) within the selected reporting period - making it a direct indicator of realised sales activity.

This metric complements Shipped Revenue and Shipped COGS, forming the foundation for most performance and profitability analyses in Amazon’s retail reporting systems.

Key Components:

1. Shipped Revenue: The total sales value generated from shipped units.
2. ASP (Average Selling Price): The average price paid by customers per unit during the shipment period.

Formula:

Shipped Volume=Shipped Revenue/Average Selling Price (ASP)

Example Calculation:

• Shipped Revenue = $100,000
• ASP = $50

Shipped Volume=100,000÷50=2,000 units

Where It’s Used:

• Found in Amazon Retail Analytics (ARA / ARA Premium) and RRA (Rapid Retail Analytics) dashboards.
• Used in Weekly Business Review (WBR), Quarterly Business Review (QBR), and Vendor Growth Plan (VGP) reports.
• Core input for metrics like Shipped COGS, Sell-Through Rate, and Revenue Forecasting.

Benefits for Amazon:

• Operational visibility: Tracks shipment volume to assess fulfilment network efficiency.
• Demand insight: Identifies high-performing ASINs and growth categories.
• Forecast validation: Compares actual shipments against forecasted demand.

Benefits for Vendors:

• Performance tracking: Helps analyse which SKUs drive the most shipped sales.
• Inventory planning: Supports replenishment and production scheduling.
• Profitability alignment: Links unit volume with pricing and cost metrics.

Challenges:

• Timing gaps: May differ from ordered or received volumes due to lead times.
• ASP volatility: Promotional periods can distort unit-based trends.
• Data reconciliation: Returns and cancellations can slightly affect true shipped volume.

Why It Matters:
Shipped Volume is the clearest measure of real product movement from Amazon to customers.
It enables accurate sales performance analysis, margin tracking, and forecasting at both category and ASIN levels.

Example:
A home appliance vendor reports a Shipped Revenue of $250,000 and an ASP of $100 per unit.

Shipped Volume=250,000÷100=2,500 units shipped

This data helps the vendor adjust production planning for the next quarter based on demand trends.

In short:
Shipped Volume represents the number of units shipped to customers, calculated as Shipped Revenue ÷ ASP - a key measure of true sales activity and demand realisation on Amazon.
