Every week, your team brings fresh ideas to the table – but some can quietly destroy your margins. That brilliant new garnish or seasonal special sounds exciting until you realize it's costing you thousands without anyone noticing. Smart operators filter every suggestion through their profit targets before giving the green light.
Why creative ideas can drain profits
Your kitchen staff has good intentions. They suggest a fancy new pasta, seasonal additions, or upgraded garnishes. But these seemingly small changes can send food costs spiraling if you don't have proper controls in place.
⚠️ Watch out:
A chef who uses 50 grams of extra garnish on each plate can cost you €3,000+ per year without you noticing.
The 3-minute margin check
Before approving any new idea, run through these questions systematically:
- What's the exact cost per portion? Calculate all ingredients precisely
- What menu price can you charge? Include VAT in your calculations
- Does the food cost percentage hit your target? No exceptions without good reason
- How many portions will you realistically sell? Conservative estimates work better
- Can your kitchen handle it easily? Avoid equipment purchases or extensive training
💡 Example:
Your chef wants to add a new truffle pasta:
- Ingredient costs: €12.50 per portion
- Target food cost: 30%
- Minimum selling price excl. VAT: €12.50 / 0.30 = €41.67
- Selling price incl. 9% VAT: €45.42
Question: do you sell pastas for €45? If not, this dish doesn't fit your concept.
Set clear boundaries with your team
Your kitchen needs to understand the financial framework. From years of working in professional kitchens, I've seen how unclear expectations lead to costly mistakes.
- No unauthorized menu additions – creativity requires approval first
- No portion upgrades without running the numbers
- No recipe modifications to existing dishes
- Encourage innovation within established cost parameters
💡 Example conversation:
'Cool idea for that new salad! Let's first calculate what it will cost. If the food cost stays under 32%, we'll give it a try. Deal?'
Track decisions and reasoning
Document what you approved and why. This prevents repeated discussions about the same concepts. Record:
- What was the specific proposal?
- What were the calculated costs per portion?
- Why did you approve or reject it?
- What alternative solutions were considered?
Handle seasonal items differently
Limited-time specials can justify higher food costs because:
- Customers expect premium pricing
- They're temporary investments
- They can drive additional traffic
💡 Example:
Asparagus in May can have 40% food cost if you charge €32 and people are willing to pay. But the same dish in October for €18 doesn't make sense.
Speed up calculations with technology
Manual math during busy conversations doesn't work well. Tools like KitchenNmbrs let you check margin compatibility in under 30 seconds – just input ingredients and get instant food cost percentages.
How do you set up this routine? (step by step)
Determine your margin targets per category
Set your maximum food cost. For example: appetizers 28%, main courses 32%, desserts 25%. Communicate this to your team so everyone knows the framework.
Create a checklist for new ideas
Print a simple form with the 5 questions: cost per portion, selling price, food cost, expected sales, kitchen impact. Hang it in the kitchen so everyone sees it.
Schedule weekly meetings
Discuss new ideas with your team every week. Take 15 minutes to review proposals and check the numbers together. This makes it a habit, not an obstacle.
✨ Pro tip
Schedule a weekly 15-minute 'idea review' session with your kitchen team. This creates a structured time to evaluate new concepts against your margin targets, preventing costly surprises while keeping creativity flowing.

Frequently asked questions
What if my chef gets upset because I say 'no' to his idea?
Explain that it's not about the quality of the idea, but about the numbers. Offer to look together at whether the dish can be made cheaper or sold for more.
Can a seasonal special have a higher food cost?
Yes, if you can also charge more for it. Asparagus in season can have 40% food cost if guests are willing to pay €35. But check if that's realistic for your business.
Do I need to approve every small change?
Yes, because small changes add up. 10 grams of extra cheese per portion costs you €800 per year at 100 covers per week. Those aren't small amounts.
How do I quickly calculate the minimum selling price?
Divide your ingredient costs by your target food cost percentage. With €8 ingredients and 30% food cost: €8 / 0.30 = €26.67 excl. VAT, or €29.07 incl. VAT on your menu.
