Are you tired of making expensive guesses about your menu's profitability? Every restaurant owner faces this transition from gut-feeling decisions to data-driven choices. Those expensive hunches drain profits faster than you'd think.
Why guessing is so expensive
Most hospitality entrepreneurs are great hosts and cooks, but not numbers people. The result:
- You think your pasta is profitable, but your food cost is 42%
- You increase portions because guests complain, but lose €3 per plate
- Your chef orders extra because "we're almost out of salmon", while there's still 3 days' worth left
- You accept a catering job for €18 per person, but your costs are €22
⚠️ Note:
Every gut-feeling decision costs you an average of €50-200 per week. On an annual basis: €2,500-10,000 in lost profit.
The transition to numbers-based thinking
Structured decision-making doesn't mean you're no longer an entrepreneur. It means you take informed risks instead of blind guesses.
The difference:
- Guessing: "This new supplier seems cheaper"
- Structured: "This supplier is 8% cheaper, but has 2 days longer delivery time"
- Guessing: "We're doing well with food cost"
- Structured: "Our food cost is 31%, which gives us €4,200 margin room this month"
What you need to get started
You don't need everything perfect at once. Start with this basic data:
- Recipes: Exact quantities of your 10 best-selling dishes
- Purchase prices: What you actually pay per kilo/piece (not the catalog price)
- Sales figures: How much of each dish you sell per week
- Fixed costs: Rent, staff, energy per month
💡 Example:
Restaurant De Eik wanted to know if their steak was profitable:
- Steak 200g: €8.40
- Vegetables and sides: €1.80
- Sauce and butter: €0.60
Cost price: €10.80. Selling price €32 excl. VAT. Food cost: 33.8%
Conclusion: Good margin, can stay on menu.
How a system like KitchenNmbrs helps
A good hospitality app takes the math out of your hands, so you can focus on running your business:
- Automatic calculations: Enter ingredients, get your food cost instantly
- Run scenarios: "What if I reduce the portion by 20 grams?"
- Track price changes: Supplier raises prices, you see the impact immediately
- Overview per dish: Which are winners, which are losers?
The first month: from chaos to control
Week 1-2: Enter your recipes with exact quantities. Yes, it takes time, but you only do it once.
Week 3: Update your purchase prices. Check which dishes are above 35% food cost.
Week 4: Adjust your first dish. Smaller portion, different garnish, or higher price.
This systematic approach is the kind of thing you only learn after closing your first month at a loss - trust me, prevention beats painful experience every time.
💡 Example transformation:
Café Het Anker after 1 month:
- Discovered their club sandwich had 41% food cost
- Replaced expensive ham with turkey: food cost down to 29%
- Saved €180 per month on this single dish
Result: €2,160 extra profit per year, without raising prices.
Common mistakes during the transition
Mistake 1: Wanting everything perfect at once
Start with your 5 best-selling dishes. The rest comes later.
Mistake 2: Only looking at food cost
A dish with 38% food cost that you sell 200 times per week is more important than a dish with 25% food cost that you sell 5 times.
Mistake 3: Raising prices too quickly
Try adjusting portion size or ingredients first. Price increase is your last option.
The result after 3 months
Restaurants that switch from guessing to numbers-based operations see on average:
- 3-8% better food cost through more conscious portion control
- Less stress with decisions (you know what things cost)
- Faster response to supplier price changes
- More confidence in new dishes (you calculate them first)
Most importantly: you still take entrepreneurial risks, but now with the numbers on the table.
From guessing to structured: step by step
Gather basic data
Write down your 10 best-selling dishes with exact ingredients and quantities. Ask your supplier for current purchase prices. This is the foundation for all calculations.
Calculate your current food cost
Add up all ingredient costs per dish and divide by your selling price (excl. VAT). Dishes above 35% food cost have priority for adjustment.
Implement a system
Use an app like KitchenNmbrs to keep track of your recipes and prices. This way you see the impact of changes immediately and stay in control.
✨ Pro tip
Track your top 3 revenue-generating dishes for exactly 2 weeks - calculate their true food costs and you'll immediately spot which one's bleeding money. Start there for maximum impact.

Frequently asked questions
How much time does it take to switch to structured operations?
The initial setup takes about 4-6 hours to enter your recipes. After that, 10 minutes per week to update price changes. It ultimately saves you time because you can make decisions faster.
What if I discover that many dishes are too expensive?
Don't adjust everything at once. Choose 2-3 dishes first and try to lower the food cost by adjusting portion size or ingredients. Price increase is the last option.
What if my chef resists this system?
Explain that it's not about control, but about making better decisions. A chef who knows what ingredients cost can be more creative within the margins and becomes a partner in profitability.
