I'll admit something that might shock you: most restaurants lose thousands each year simply because they don't track when suppliers quietly raise prices. Food costs shift 2-4 times annually, yet menus get updated maybe twice. You're bleeding money for months without even knowing it.
How often do supplier prices change?
Suppliers shift their pricing more frequently than most owners realize. Meat, fish, and dairy see the most volatile swings.
- Meat and fish: 3-6 times per year (seasonality, supply/demand)
- Vegetables: 4-8 times per year (highly seasonal)
- Dairy: 2-4 times per year
- Dry goods: 1-3 times per year
💡 Example:
You buy salmon for €18/kg. In January, the price jumps to €22/kg (+22%). You don't catch this until April.
- January-March: 3 months of underpricing
- At 50 salmon dishes/month: €200 loss per month
- Total damage: €600 in 3 months
Why don't restaurants adjust?
Several factors keep menus stuck while costs climb:
- Zero visibility: You simply don't know prices have jumped
- Printing expenses: Fresh menus cost real money
- Customer pushback: Fear of complaints about higher prices
- Manual chaos: Tracking everything by hand eats too much time
⚠️ Watch out:
Small increases feel harmless. But with 1000 covers monthly, an extra €0.50 cost per dish drains €6000 from your annual profit.
The impact on your food cost
Supplier prices climb while menu prices stay frozen? Your food cost percentage automatically balloons. This directly devours your margin.
💡 Example calculation:
Steak on menu: €32.00 (€29.36 excl. VAT)
- Previous ingredient costs: €9.00 (30.7% food cost)
- Current ingredient costs: €11.00 (37.5% food cost)
- Gap: 6.8 percentage points higher
At €500,000 annual revenue, this hemorrhages €34,000 yearly!
How often do restaurants check their prices?
Data from independent restaurants reveals:
- 35% never systematically monitor supplier prices
- 40% only react to massive changes (>10%)
- 20% review their core ingredients monthly
- 5% run automated tracking systems
That means 75% of restaurants regularly hemorrhage cash due to stale cost data. Something most kitchen managers discover too late - after months of eroded margins have already damaged their bottom line.
Signs that your prices are outdated
These red flags should trigger immediate price reviews:
- Food cost creeps upward without obvious cause
- Supplier invoices exceed your projections
- Competitors bump prices while you stay put
- Seasonal items have gotten pricier
- Margins shrink despite packed dining rooms
💡 Real-world example:
Restaurant De Smaak ignored pricing for 6 months. The damage:
- Food cost jumped from 28% to 35%
- 7 percentage points × €400,000 revenue = €28,000 vanished
- Single afternoon of price updates could've prevented this
How technology solves this
Modern tools like KitchenNmbrs instantly reveal price change impacts:
- Automatic recalculation: Adjust one ingredient price, every dish updates instantly
- Food cost alerts: Spot dishes that bust your target margins immediately
- Side-by-side comparison: Old vs. new cost prices in single view
- Suggested selling price: Calculator shows exactly what your new menu price should be
This stops price increases from silently devouring profits for months on end.
How do you prevent price increases from eating away your profit?
Check your top 5 ingredients monthly
Look at the prices of your 5 most expensive ingredients every month. These have the biggest impact on your food cost. Compare with last month and watch for increases above 5%.
Calculate the impact on your food cost
When a price rises, immediately calculate what this means for your food cost percentage. Use the formula: new ingredient costs / selling price excl. VAT × 100.
Adjust menu price or find alternatives
Is your food cost rising above 35%? Then you have two options: raise your menu price or find a cheaper alternative ingredient. Don't wait too long to adjust.
✨ Pro tip
Track your 8 most expensive ingredients weekly using a simple spreadsheet. Note every price shift immediately - even 5% increases compound into serious margin damage over 90 days.
Calculate this yourself?

Frequently asked questions
How often should I monitor supplier pricing?
Review your 5 most critical ingredients monthly at minimum. Seasonal products like vegetables and fish deserve weekly attention since they fluctuate rapidly.
What constitutes normal annual price inflation?
Food costs typically climb 3-8% yearly on average. Meat and fish can spike higher due to seasonal shifts and supply constraints. Anything above 15% signals exceptional market conditions.
Should I wait for suppliers to announce increases?
Suppliers have zero obligation to warn you about price hikes. You'll often discover changes only when the next invoice arrives - after weeks of profit erosion.
How can I raise menu prices without losing customers?
Increase gradually (maximum 10% at once) and communicate transparently about quality commitments. Diners understand ingredient costs rise, but they won't tolerate businesses operating at losses indefinitely.
