Understanding Rate of Sales (ROS)

Rate of Sales, often referred to as Sales Velocity or Units Per Store Per Week (UPSW), is a critical retail metric used to measure the productivity of a product within a distribution network. Unlike total sales volume, ROS levels the playing field, allowing retailers to compare the performance of products regardless of how many stores carry them.

Why ROS is Important for Your Business

  • Inventory Management: ROS helps in forecasting how much stock is needed to prevent out-of-stock situations.
  • Benchmarking: It allows you to compare a new product's performance against category leaders.
  • Distribution Decisions: High ROS indicates a product should likely be expanded to more stores, while low ROS suggests it might need a price change or removal.

The ROS Formula

Rate of Sales = Total Units Sold / (Number of Stores × Number of Weeks)

Practical Example

Imagine you are selling a "Premium Coffee Blend":

  • Total Units Sold: 2,400 bags
  • Distribution: 120 stores
  • Duration: 4 weeks

Calculation: 2,400 ÷ 120 ÷ 4 = 5.00 UPSW

This means that on average, every store in your network is selling 5 bags of coffee every week. If your target for this category is 4.0 UPSW, your product is over-performing.

How to Improve Your Rate of Sales

If your ROS is lower than expected, consider the following strategies:

  1. Optimized Placement: Ensure the product is at eye level or in high-traffic areas like endcaps.
  2. Promotional Activity: Run temporary price reductions or "buy one get one" offers to stimulate trial.
  3. Marketing Support: Increase digital advertising or social media presence targeted at the specific store regions.
  4. Packaging Review: Ensure the packaging clearly communicates the product benefits compared to competitors on the same shelf.
