I'll admit it - I used to think kitchen data was only for spreadsheet wizards and MBA graduates. Your kitchen produces mountains of data every day, but most of us think we're 'not good with numbers' and ignore this goldmine. Kitchen data is actually simpler than you think and can save you thousands of euros per year.
Your kitchen is a data machine
Hundreds of things happen in your kitchen daily that reveal crucial business insights. The problem? You don't recognize it as 'data', so you ignore it completely.
💡 Example of invisible data:
- Your chef uses 250 grams of steak instead of 200 grams
- On Tuesday you sell 40% less pasta than on Saturday
- Of your 15 dishes, 3 barely sell
- You throw away €80 worth of vegetables every week
These are all numbers. And each number shows you exactly where money's slipping away.
Why you're underestimating yourself
Most hospitality entrepreneurs have the wrong picture of what 'working with data' actually means. You probably imagine:
- Complicated Excel sheets
- Hours of calculating and formulas
- Complex analyses
- Statistics you don't understand
But kitchen data is much simpler. It's really about questions like:
- Which dish generates the most revenue?
- Where does my money disappear?
- What does this dish actually cost me?
- What can I eliminate without hurting sales?
⚠️ Note:
You don't need Excel mastery to control your numbers. It's about asking smart questions, not mastering complicated formulas.
The power of simple numbers
A few basic numbers reveal more than you'd expect. Take food cost - the percentage of your selling price that goes straight to ingredients.
💡 Example food cost calculation:
You sell a pasta for €18.50 (incl. 9% VAT):
- Selling price excl. VAT: €18.50 / 1.09 = €16.97
- Ingredient costs: €5.80
- Food cost: (€5.80 / €16.97) × 100 = 34.2%
This single number tells you if this dish is profitable.
Standard food cost ranges between 28-35%. Above 35%? You're probably losing money on that dish. It's really that straightforward.
What you're missing without data
Without numbers, money disappears daily without you noticing:
- Oversized portions: 50 grams extra meat per portion costs you €3,000+ annually
- Poor purchasing decisions: Too much of slow-moving products
- Underpriced dishes: You're still using old ingredient prices
- Waste blindness: You can't see where it's hemorrhaging
💡 Example of missed profit:
Restaurant with 100 covers per day, 6 days per week:
- 5 grams extra butter per plate: €1,872 per year
- 1% higher food cost due to outdated prices: €5,000 per year
- €10 waste per day: €3,120 per year
Total: €9,992 per year in missed profit
This is the kind of thing you only learn after closing your first month at a loss - small leaks add up to massive hemorrhaging over time.
The first step is the hardest
The real problem isn't that you're bad with numbers. The problem is you don't know where to begin. So you don't.
Start small. Pick just one thing:
- Calculate the food cost of your 3 top-selling dishes
- Count what you discard this week
- Identify which dishes sell the least
That's it. No complex analyses. Just one simple number that reveals something crucial about your kitchen.
Tools make it easy
You don't have to track everything manually. Tools like KitchenNmbrs automatically calculate your food cost, track waste, and show you which dishes generate the most revenue.
But the crucial thing is starting. With pen and paper, Excel, or an app. Doesn't matter. What matters is stopping the belief that numbers are too difficult for you.
⚠️ Note:
Don't attempt everything simultaneously. Pick one number, master it, then build from there. Perfection kills progress.
How do you start with kitchen data? (step by step)
Choose one dish to analyze
Pick your best-selling dish. Add up all ingredient costs, including garnish and sauces. Divide this by your selling price excl. VAT and multiply by 100 to get your food cost percentage.
Track your waste for one week
Note every day what gets thrown away and what it cost. Add it up at the end of the week. This gives you immediate insight into where money is leaking without getting anything in return.
Compare sales figures per dish
Look at which dishes sell frequently and which barely sell. Calculate how much time and ingredients you put into dishes that are hardly ordered. This helps you optimize your menu.
✨ Pro tip
Track your top 3 revenue-generating dishes for exactly 14 days - if those are profitable, you've solved 80% of your kitchen's financial puzzle. Stop overthinking the rest until you master these three.
Calculate this yourself?
In the KitchenNmbrs app you can do this in just a few clicks. 7 days free, no credit card.

Frequently asked questions
Do I need Excel expertise to work with kitchen numbers?
Not at all - you only need basic math: addition, subtraction, multiplication, and division. Most calculations are simple formulas you can handle with a calculator.
How much time does tracking my numbers actually take?
Start with just 10 minutes daily. Check one dish's food cost, note what you threw away, done. Once it becomes routine, it's automatic.
Which numbers matter most for tracking?
Focus on food cost per dish, daily waste, and sales per dish first. These three reveal exactly where you're making money and where you're bleeding it.
What if my numbers show I'm losing money?
Then you finally have real insight into what's happening. Now you can take targeted action: adjust portions, raise prices, or eliminate dishes that don't pay off.
Can I track numbers without special software?
Absolutely - start with pen and paper or basic Excel. The crucial thing is beginning to track, not which tool you use.
How do I know if my food cost is acceptable?
Standard restaurant food cost runs 28-35%. Above 35%? Examine your portion sizes and ingredient prices immediately.
What's the biggest mistake restaurants make with portion control?
They eyeball portions instead of weighing them consistently. A 20-gram variance in protein per dish can cost you thousands annually without you realizing it.
