Same-Store Sales Growth (SSSG)
Same-Store Sales Growth measures the revenue change for retail outlets or restaurant locations that have been open for at least twelve months, isolating organic performance from the distortion caused by new store additions.
When a retail chain or quick-service restaurant company adds new stores, its total revenue naturally rises even if existing stores are performing poorly. Investors who focus only on total revenue growth can therefore be misled about the underlying health of the business. SSSG — also called like-for-like (LFL) growth or comparable-store sales growth — corrects this by measuring only the performance of stores in the base period that are still operating in the comparison period, typically requiring a minimum maturity of twelve months.
In India, SSSG became a closely watched metric as organised retail and QSR chains proliferated. Westlife Foodworld, which operates McDonald's restaurants in west and south India, and Jubilant FoodWorks, which runs Domino's Pizza, both published SSSG as a primary operating KPI. During the post-pandemic recovery phase, SSSG figures were elevated partly because the comparison period (2020-21) was severely disrupted by lockdowns — investors had to normalise for this base effect when assessing whether the reported growth reflected genuine demand recovery or statistical distortion.
Positive SSSG can come from three sources: more customer footfall (traffic growth), higher average transaction value per visit (ticket size growth), or both. Premium QSR chains in India saw ticket size expansion as customers added more items per order, while value-focused chains saw traffic recovery driving their SSSG. Disaggregating SSSG into traffic and ticket contributions helps assess whether growth is broad-based or driven by a single lever.
For physical retailers such as Avenue Supermarts (D-Mart), SSSG is complicated by the company's unique format — large-format hypermarkets with a no-frills approach. D-Mart's SSSG was occasionally lower than smaller-format competitors not because stores were performing poorly in absolute terms but because very large stores take longer to reach maturity and because the metric is affected by store-level space additions at existing locations.
Analysts use SSSG alongside store count growth and average store revenue to build a complete picture of a retailer's unit economics. A chain with 15 per cent SSSG and aggressive new store additions is compounding rapidly; one with flat SSSG relying entirely on new stores for revenue growth raises questions about market saturation or operational execution at the store level.
