Same-Store Sales Growth (Comparable Sales)
Revenue growth from stores open for at least one full year, excluding new openings
What is Same-Store Sales Growth (Comparable Sales)?
Same-store sales growth is the percentage change in sales from stores that were open in both the current and prior period. It shows how well existing stores are performing, without the effect of opening or closing shops.
It is a core retail measure because it isolates real underlying growth.

How to calculate it
Subtract prior-period sales for the comparable stores from their current sales, divide by prior-period sales, and multiply by 100.
For example, if comparable stores sold 40,000,000 this year against 38,000,000 last year, growth is 5.3%.
Include only stores open for the full comparison period, and be consistent in how you treat refurbished or relocated stores.
