A steakhouse owner watches beef costs climb 15% in three months while keeping menu prices frozen. This common scenario forces a choice: absorb the loss or risk customer backlash with a price increase. Smart pricing decisions require data-driven timing and clear justification.
When price adjustments are necessary
Price adjustments respond directly to cost changes. The main drivers:
- Supplier price increases: Raw materials become more expensive
- Labor costs: Union wage increases, minimum wage bumps
- Energy costs: Gas, electricity, water
- Rent increases: Often tied to inflation indexes
⚠️ Watch out:
Many operators delay price adjustments too long and bleed money for months without realizing it.
The 5% rule for cost changes
A practical guideline: if your total costs rise by more than 5%, consider a price adjustment. This prevents gradual increases from eroding your profit margins.
💡 Example:
Your ribeye has a food cost of 30% (€9 on €30 excl. VAT):
- Beef jumps from €32/kg to €36/kg (+12.5%)
- New ingredient costs: €9 × 1.125 = €10.13
- New food cost: 33.8% (was 30%)
Action needed: food cost rises by 3.8 percentage points
Frequency of price adjustments
Most restaurants follow this pattern:
- 1-2 times per year: Structural adjustments (wages, rent, utilities)
- Emergency basis: For major raw material spikes (>10%)
- Seasonal: Products with volatile pricing
💡 Example timing:
Bistro De Eekhoorn adjusts prices:
- January: Union contract increase 3.2%, energy costs +8%
- July: Summer menu with seasonal ingredients
- September: Beef +15% due to drought conditions
Result: 3 adjustments in 2023, but all justified by numbers
How do you calculate the new price?
Use this formula to determine your new minimum selling price:
New price excl. VAT = New ingredient costs / (Target food cost % / 100)
💡 Calculation example:
Pasta carbonara - ingredient costs jump from €5.10 to €5.85:
- Target food cost: 30%
- New minimum price: €5.85 / 0.30 = €19.50 excl. VAT
- With 9% VAT: €19.50 × 1.09 = €21.26
- Round to: €21.50
From €18.50 to €21.50 = increase of €3.00 (16.2%)
Communication with guests
Clear communication reduces pushback. Based on real restaurant P&L data, establishments that explain price changes see 40% fewer complaints than those that don't:
- Timing: Announce 2-4 weeks ahead
- Reason: Cite specific cost increases, not vague "inflation"
- Quality: Emphasize what remains unchanged
⚠️ Watch out:
Avoid "due to circumstances" - sounds like an excuse. Be specific about cost increases.
Alternatives to price increases
Sometimes you can sidestep raising prices by:
- Adjusting portion size: 10% smaller portion = 10% lower costs
- Recipe modifications: Substitute expensive ingredients with alternatives
- Menu engineering: Promote higher-margin dishes
- Supplier changes: Source cheaper alternatives
💡 Example adjustment:
Salmon jumps from €28/kg to €34/kg (+21%):
- Option 1: Raise price from €26.50 to €31.50
- Option 2: Cut portion from 180g to 150g (same price)
- Option 3: Switch to sea bass (€24/kg)
Your choice depends on target market and brand positioning
How do you determine if a price adjustment is needed?
Check your current food cost per dish
Calculate the current food cost for your 10 best-selling dishes. Add up all ingredients and divide by selling price excl. VAT. Note which dishes come in above 35%.
Monitor supplier price changes
Keep track weekly of which products rise or fall in price. Note percentage change per product. Focus on ingredients that make up more than 20% of your recipe costs.
Calculate impact on total costs
If an ingredient becomes 10% more expensive and makes up 30% of your recipe costs, your total costs rise by 3%. At more than 5% total cost increase, price adjustment is worth considering.
Determine new selling price
Use the formula: new ingredient costs divided by desired food cost percentage. Round to logical prices (e.g., €21.26 becomes €21.50).
Plan communication and timing
Announce price changes 2-4 weeks in advance. Choose quiet periods (not during busy seasons). Explain why prices are rising without complaining about costs.
✨ Pro tip
Review food costs on your top 8 dishes quarterly - not monthly. If any dish jumps more than 2 percentage points (like 28% to 30%), investigate immediately and adjust within 30 days.

Frequently asked questions
How often can you raise prices without losing customers?
Most restaurants can adjust prices 1-2 times per year if backed by solid numbers. Guests accept this if you're transparent about cost increases and maintain consistent quality.
What if my competitor doesn't raise prices?
Check if your competitor truly matches your quality and service levels. They might have different cost structures or accept thinner margins. Focus on your own financials, not theirs.
How do I calculate the effect of labor cost increases on my prices?
Labor typically represents 25-35% of total costs. A 4% wage increase means 1-1.4% higher overall costs. You can offset this by raising your top-selling dishes 3-5%.
What do I tell guests who complain about price increases?
Be direct about cost increases: 'Our suppliers raised prices 15%, but we're maintaining the same quality.' Skip vague references to inflation or economic hardship.
