Discount Frequency: Weekly, Monthly, or Seasonal — Which Protects Restaurant Margin?

An operator running three nearly identical branches in Tekirdağ Süleymanpaşa let us A/B/C test discount cadence for 6 months. Branch A ran 15% off every week, Branch B ran 25% off once a month, Branch C ran 35% off once per season. We only measured one thing: net margin after all costs.

Experimental setup

All three branches had similar revenue, similar neighborhood demographics, and the same 60-item menu. We kept the gross food cost frozen at 33% so the only variable that mattered was the promotional rhythm itself.

Each branch rotated the same 12-item discount pool. Staff schedules and marketing channels were standardized. We tracked daily revenue, basket size, and the percentage of orders that included a discounted item.

Net margins after 6 months

Branch A (weekly 15%) finished at 11.4% net margin. The unexpected problem: customers learned the discount days within four weeks and stopped showing up on non-discount days. Traffic shifted but did not grow.

Branch B (monthly 25%) finished at 18.7% net margin — the clear winner. The monthly surprise effect did not erode regular-price sales, and each promo created a social-media push moment.

Branch C (seasonal 35%) finished at 14.9%. The launch week drove 2.3x normal revenue, but in the following weeks customers told us "your normal prices feel expensive now." Anchor price was damaged.

Three lessons we took away

• Weekly discounts train habit — and that habit drags your perceived price downward.
• Monthly discounts preserve "opportunity" feel — highest net margin landed here.
• Seasonal discounts spike traffic but leave a long shadow — only use them for inventory clearance or a new-branch launch.

The practical takeaway for most operators: default to a monthly cadence, rotate which items get discounted, and never run more than two seasonal events per year on the same menu.

FAQ

Is weekly discounting ever useful? Only when you target a single slow weekday (e.g. Tuesday) and rotate the discounted item every week, so customers cannot pattern-match.

How should I announce a monthly promo? Combine an in-menu QR campaign banner, an email blast, and an Instagram story 48 hours before, and close it 24 hours after — scarcity matters.

When does a seasonal discount make sense? New branch launch, menu reset, or genuine over-stock. More than twice a year and your anchor price collapses permanently.
