SSSG (Same Store Sales Growth)
SSSG, or Same Store Sales Growth, measures the change in revenue from outlets that were operating in both the current and the comparison period, excluding new and closed stores.
SSSG isolates how well your existing outlets are performing by removing the effect of expansion. If total revenue grows only because you opened three new stores, SSSG will show that the original stores are flat.
Formula: SSSG % = ((Sales this period − Sales same period last year) ÷ Sales same period last year) × 100, counting only outlets open through both periods.
Loyalty programmes move SSSG directly, because repeat visits from existing customers are same-store revenue by definition. Tracking enrolled-customer revenue share alongside SSSG shows how much of the growth your programme is responsible for.
