Same-Store Sales
Also called: like-for-like sales, SSSG
What is Same-Store Sales?
Same-store sales compares revenue only at outlets that were open across both periods being compared. It strips out the growth that came purely from opening new locations.
Why Same-Store Sales matters
Total revenue growth flatters any expanding business. Same-store sales answers the harder question: are the outlets you already had performing better than last year?
Same-Store Sales formula
Same-store growth % = (Current period sales − Prior period sales) ÷ Prior period sales × 100
Include only outlets trading in both periods.
How Same-Store Sales works in practice
Compare against the same period last year to neutralise seasonality, and exclude outlets that were closed for renovation. Flat same-store sales alongside rising totals means growth is being bought, not earned.
