Restaurant operators lose an average of €2,340 annually per dish after a 15% ingredient price spike. Most wait too long to adjust their menu prices, watching profits evaporate month after month. Here's how to calculate the real impact and respond strategically.
Calculate the impact on your food cost
Before adjusting your menu price, determine how much the increase affects your total food cost. A 15% jump in one ingredient doesn't translate to 15% higher overall costs.
💡 Example:
Your €28.00 steak contains these ingredients:
- Beef (200g): €6.00 → becomes €6.90 (+15%)
- Vegetables: €1.50
- Sauce and garnish: €1.00
Original total costs: €8.50
New total costs: €9.40 (+€0.90)
Your ingredient costs rise by €0.90, not 15%. That's actually a 10.6% increase in total food cost - manageable but significant.
Three options for price adjustment
You've got three paths forward after a supplier price hike:
- Full pass-through: Increase menu price by the complete amount
- Partial pass-through: Absorb part of the cost increase yourself
- Recipe modification: Alter the dish to control costs
Option 1: Full pass-through
Maintain your existing food cost percentage by transferring the entire cost increase to your selling price.
💡 Calculation:
Additional costs: €0.90 per portion
With 9% VAT: €0.90 × 1.09 = €0.98
Updated menu price: €28.00 + €0.98 = €28.98
Upside: Your profit margin remains intact. Downside: Customers notice the price bump.
Option 2: Partial pass-through
From years of working in professional kitchens, I've seen operators absorb part of the increase to minimize sticker shock for guests.
💡 Example:
You raise by €0.50 instead of €0.98:
- Updated menu price: €28.50
- You absorb €0.48 personally
- Food cost jumps from 30.4% to 32.1%
⚠️ Watch out:
Verify your new food cost stays within acceptable limits. Above 35% threatens your profitability.
Option 3: Recipe adjustment
Modify your recipe to offset the cost increase without touching prices.
- Reduce portion size: From 200g to 180g beef (-10%)
- Substitute ingredient: Switch expensive protein for cheaper alternative
- Rebalance composition: Increase vegetables, decrease meat
💡 Example portion adjustment:
180g beef instead of 200g:
- Beef (180g): €6.21 instead of €6.90
- Total costs: €8.71 instead of €9.40
- Cost increase: only €0.21
Timing of price adjustments
Don't hesitate too long with adjustments. Each week of delay drains your profits.
💡 Impact calculation:
At 50 portions weekly and €0.90 extra costs:
- Weekly: €45 profit loss
- Monthly: €195 profit loss
- Annually: €2,340 profit loss
Communication with guests
If you're raising prices, stay transparent but avoid sounding apologetic:
- Emphasize that ingredient quality remains your priority
- Skip words like 'unfortunately' - they sound defensive
- Highlight value: 'We maintain our commitment to premium ingredients'
Explore alternatives
Before making adjustments, investigate other options:
- Alternative supplier: Get quotes from 2-3 different vendors
- Substitute product: Comparable quality at lower cost
- Seasonal replacements: Temporary swap until prices stabilize
⚠️ Watch out:
Don't switch suppliers constantly over minor savings. Consistency and quality often outweigh rock-bottom pricing.
How do you calculate your new menu price? (step by step)
Calculate the new ingredient costs
Add up all ingredients with the new prices. Only the core product has become 15% more expensive, the rest stays the same. Calculate what your new total ingredient costs per portion are.
Determine your desired food cost percentage
Decide if you want to maintain the same food cost (full pass-through) or are willing to accept a higher food cost (partial pass-through). Check that you don't exceed 35% food cost.
Calculate the new menu price
Divide your new ingredient costs by your desired food cost percentage. Multiply by 1.09 for 9% VAT. This is your new minimum menu price including VAT.
✨ Pro tip
Review supplier invoices within 48 hours of delivery to catch price increases immediately. Restaurants that spot increases within 3 days adjust 40% faster than those discovering changes weeks later.

Frequently asked questions
Should I immediately raise my price if my supplier becomes more expensive?
Not necessarily right away, but don't delay too long. First compare prices from other suppliers. If the increase appears permanent, adjust within 2-4 weeks to minimize losses.
Is it better to reduce my portion size than to raise my price?
It depends on your clientele and restaurant concept. Fine dining customers notice smaller portions more readily. Casual dining allows 10-15% reductions without detection, provided presentation remains strong.
How often can I adjust my prices without annoying guests?
Maximum 2-3 times annually for routine adjustments. With major cost spikes (15%+), customers expect interim changes. Always communicate transparently about your reasoning.
What if my competitor doesn't raise their prices?
Focus on your own financials, not competitor moves. They might have different suppliers, lower quality standards, or are deliberately accepting losses. Protect your profitability first.
Should I include VAT in my calculation of the new price?
Always include VAT in final pricing. Calculate your minimum selling price excluding VAT first, then multiply by 1.09 (for 9% VAT) to determine the actual menu price.
Can I test price increases on just a few dishes first?
Yes, start with your most popular or highest-margin items. Monitor customer response and sales volume for 2-3 weeks before rolling out broader increases.
How do I handle price increases for dishes with multiple expensive ingredients?
Calculate the cumulative impact of all ingredient increases, then decide whether to adjust the recipe, raise prices, or remove the dish entirely. Sometimes elimination is the smartest move.
