Same-Store Sales

Same-store sales, also called comparable-store sales or "comps," measure revenue growth from stores or locations that have been open for at least twelve months. By excluding newly opened stores, this metric isolates organic demand trends from growth driven by geographic expansion. A retail company can report strong total revenue growth while same-store sales are declining, it just means they are opening new stores faster than existing ones are losing traffic. Eventually, the new store pipeline runs out and declining comps catch up. Same-store sales are the single most important metric for retail analysts because they reflect the fundamental health of the brand. Positive comps mean the brand is gaining market share at each location through a combination of more transactions, higher average transaction values, or both. Many retailers break out same-store sales into traffic (number of transactions) and average ticket (revenue per transaction) to provide more granularity. For S&P 500 retailers and restaurant companies, same-store sales trends are leading indicators of consumer health. When Walmart, Target, and McDonald's all report declining comps, consumer spending is weakening broadly. When they report accelerating comps, consumers are feeling confident. For operators selling consumer products or services, same-store sales at major retailers serve as a proxy for the overall demand environment. The concept extends beyond retail, SaaS companies use "net dollar retention" as their version of same-store sales, measuring revenue growth from existing customers.
