PCT

 On Amazon, PCT is used throughout Vendor Central, Seller Central, and Retail Analytics dashboards to quantify relative changes or proportions - for example, sales growth %, conversion rate %, Buy Box %, or defect rate %. It standardises performance metrics into a universally comparable format.

How It Works:

• Formula:
• Example: If a product sells 200 units out of a total 1,000 units in its category, its share = 20% (PCT).

Common Use Cases on Amazon:

• Sales Growth %: Measures increase or decrease in sales vs previous period (WoW, MoM, YoY).
• Conversion Rate %: Percentage of page visitors who make a purchase.
• Buy Box %: Time or sessions where the vendor’s offer held the Buy Box.
• Instock %: Portion of time a product was available for purchase.
• Return Rate % / Defect Rate %: Portion of items returned or reported defective.

Benefits:

• Comparability: PCT enables cross-category or cross-period analysis.
• Clarity: Highlights proportional performance rather than absolute numbers.
• Decision-making: Helps identify trends and areas of improvement quickly.

Challenges:

• Can be misleading without context - e.g., a 100% growth rate from a small base might not be meaningful.
• Aggregation bias: Combining percentages from different datasets can distort interpretation.

Why It Matters:
Percentages are Amazon’s universal reporting language. Whether analysing sales, advertising, or operational KPIs, PCT values translate raw data into insights, making performance measurable and comparable.

Example:
A vendor’s Q2 sales grew from $500K to $600K.In short:
PCT (Percentage) expresses a metric or change as a fraction of 100, serving as a standard unit of measurement across Amazon’s reporting dashboards for sales, operations, and performance analysis.
