Every restaurant owner knows it: you want to finally get your numbers in order, but that quiet moment never comes. Between orders, staff and guests, admin keeps piling up. The result: you have no idea where your profit is leaking and you're flying blind on gut feeling.
The illusion of the quiet moment
"Next week I'll calculate everything." "After the weekend rush, I'll tackle the numbers." "Once we're past the holiday season, I'll figure out those cost prices." Sound familiar? You're not alone.
The problem: that quiet moment never comes. And if it does, you're so exhausted that crunching numbers is the last thing you feel like doing.
💡 Example:
Marco runs a bistro. Every day he says: "Tonight I'll calculate what that steak really costs." But every evening:
- 19:00: Last guests leave, cleaning up
- 20:30: Dropping off staff, cashing out
- 21:15: Home, too tired to calculate
Result: after 6 months still no idea if that steak is profitable.
Why it always runs over in practice
Calculating numbers feels like a massive undertaking. You think you need hours for it. So you put it off until you "really have time." But that time doesn't come, because:
- The business keeps running: Even on quiet days there are deliveries, cleaning, prep work
- You're exhausted: After a long day you want to go home, not calculate
- It feels overwhelming: Where do you start? Which numbers do you need?
- You have no system: Everything's scattered, searching takes forever
The real cost of delay
While you wait for that quiet moment, your profit bleeds away. Every day you don't know what things cost, you lose money.
⚠️ Watch out:
If your food cost is 5% higher than you think, that costs you €2.000 at €40.000 monthly revenue. Per year: €24.000 in lost profit.
💡 Example:
Linda thought her pastas had 25% food cost. After she finally calculated it:
- Actual food cost: 38%
- Difference: 13 percentage points
- At €15.000 pasta revenue per month: €1.950 missed
Per year: €23.400 in profit she didn't see.
Why small steps work better
The solution isn't making more time. The solution is using less time per session. Instead of a whole afternoon on numbers, you do 10 minutes a day.
- 10 minutes a day: Doesn't feel like a chore
- Between other tasks: While coffee brews, while oven heats up
- Immediate result: You see right away what one dish costs
- Building momentum: After a week you've calculated 5 dishes
Most kitchen managers discover too late that their biggest mistake wasn't waiting for the perfect moment - it was thinking they needed one at all. The restaurants that nail their food costs? They squeeze calculations into tiny pockets of time throughout their day.
The momentum of small wins
Once you see what one dish really costs, you want to know more. That first calculation gives energy for the next. Within a month you have an overview of your entire menu.
💡 Example:
Tom started with his bestseller: the hamburger. Result:
- Ingredients: €4.80
- Selling price: €16.50 excl. VAT
- Food cost: 29% - great!
That one calculation gave him confidence. Next day: the fish. Then the salad. After two weeks: entire menu calculated.

Start with one dish

Look up your purchase prices
Get your latest supplier invoices. Note what you pay per kilo, liter or unit for each ingredient. This takes 5 minutes, not an hour.
Calculate the cost price
Add up how many grams/ml you use per portion. Multiply by the purchase price. Add everything up for the total cost per dish.

Frequently asked questions
How long does it take to calculate one dish?
If you have the ingredients and prices at hand: 5-10 minutes. Gathering prices takes the most time, but you only need to do that once.
What if I don't have time to go through invoices?
Start with estimates from your supplier or check their website. Perfect numbers aren't needed, realistic ones are. You can always refine later.
Do I need to calculate my entire menu right away?
No, start with your 3-5 best-selling dishes. Those account for 80% of your profit. You can do the rest later.
What if my numbers come out higher than expected?
Then at least you know where you stand. You can now make conscious choices: raise prices, adjust portions or find cheaper ingredients.
How do I keep track of this without it piling up again?
Use a system you always have with you, like an app on your phone. Update prices when you get new invoices, not as a big task but in between.
Should I calculate labor costs into my dish prices too?
Start with just ingredient costs first. Once you've got those dialed in after 2-3 weeks, then add labor calculations on top.
