SSSG (Same Store Sale Growth)

Same Store Sales Growth, or SSSG, measures how much your existing restaurant outlets are growing in sales over a period of time—usually year-over-year or month-over-month. Unlike total sales, which can be boosted just by opening new branches, SSSG focuses only on outlets that have been operating for at least a year. This way, it gives you a clear picture of how your core business is performing.

Why It Matters:

SSSG is one of the most important benchmarks for restaurant growth because it strips away the “noise” of expansion. Adding new stores will obviously increase your overall sales, but that doesn’t always mean your brand is stronger. SSSG tells you if the restaurants you already have are selling more today than they were before.

Here’s why it’s valuable:

• It reflects true customer demand and loyalty.

• It shows whether your marketing and service improvements are working.

• Investors and stakeholders often use SSSG as a health check for your brand.

A positive SSSG means your existing outlets are growing, which is a sign of customer satisfaction and brand strength. A negative SSSG, on the other hand, can indicate declining footfall, weak promotions, or operational inefficiencies that need urgent attention.

Formula:

Example:

This means your existing store grew by 15% compared to last year—without relying on new openings.

Pro Tip for Growth:

Improving SSSG often comes down to maximizing customer spend and frequency at the outlets you already own. Smart loyalty programs, upselling strategies, targeted offers, and a consistent guest experience are all ways to push your SSSG higher.

Think of SSSG as your “same kitchen, bigger appetite” metric—it tells you if guests are enjoying their meals with you more often and spending more each time.

One-line takeaway:

SSSG measures the real strength of your existing outlets, proving whether growth is genuine or just expansion-driven.
