The profitability of your dishes is hidden in a maze of numbers. You see your total revenue, but not which dishes really contribute to your profit. Without oversight, you might be selling mostly your least profitable items, while the real goldmines remain underexposed.
The problem: hidden profit makers
Many restaurant owners think their most popular dishes also generate the most revenue. But popularity says nothing about profitability. Your carbonara might be #1 in sales, but generates less profit per plate than your less popular beef tenderloin.
💡 Example:
Restaurant De Smaak sells per week:
- Carbonara: 50x sold, €3.20 profit per plate = €160
- Beef tenderloin: 15x sold, €12.80 profit per plate = €192
The beef tenderloin generates more profit, but seems less successful.
Why this is so hard to see
The problem lies in the different variables that determine your profit margin:
- Food cost percentage: varies enormously per dish
- Selling price: higher price doesn't always mean more profit
- Popularity: volume sometimes compensates for low margin
- Seasonal fluctuations: ingredient prices change constantly
Your POS system only shows revenue per dish. The costs remain invisible unless you track and calculate them manually.
The hidden costs per dish
Each dish has its own cost structure that isn't directly visible:
💡 Example steak vs. pasta:
Steak (€32.00 menu price):
- Meat: €12.50
- Side dish: €2.30
- Sauce: €1.20
- Total food cost: €16.00 (55% of €29.36 excl. VAT)
Pasta (€18.50 menu price):
- Pasta + sauce: €3.20
- Cheese: €1.80
- Garnish: €0.80
- Total food cost: €5.80 (34% of €16.97 excl. VAT)
Pasta generates €11.17 profit, steak €13.36 - but you don't see this in your register.
The menu engineering problem
Without insight into profitability per dish, you make wrong decisions:
- Marketing: you might promote your least profitable dishes
- Menu placement: loss-making items get top positions
- Staff advice: your team doesn't know which dishes to recommend
- Price adjustments: you raise prices on the wrong items
⚠️ Note:
Many restaurants focus on revenue per dish instead of profit per dish. This causes them to sell mostly their least profitable items harder.
The time factor
Manually calculating which dishes generate the most profit takes enormous time:
- Look up all ingredient costs per dish
- Calculate food cost percentage
- Pull sales data from your POS system
- Calculate profit contribution per dish
- Put everything in Excel and analyze
You do this analysis at most once a year. But ingredient prices change monthly, so your insights quickly become outdated.
How KitchenNmbrs solves this
With a system like KitchenNmbrs you immediately see which dishes are real profit makers:
💡 Real-time insight:
- Automatic food cost calculation per dish
- Profit margin in euros and percentages
- Overview of best and worst performers
- Updates when supplier prices change
For example, you see that your Caesar salad is popular (30x per week), but only generates €2.10 profit per plate. While your lamb shank sells less often (8x per week), but generates €18.50 profit per portion.
The impact on your decisions
With this insight you can take targeted action:
- Menu engineering: promote your most profitable dishes
- Staff training: teach your team to recommend the right items
- Pricing strategy: raise prices on popular but low-profit items
- Purchasing: focus on ingredients for your best performers
How do you get insight into your most profitable dishes?
Calculate the food cost of each dish
Make a list of all ingredients per dish with exact quantities and prices. Add everything up: main ingredient, side dish, sauces, oil, butter. Divide this by your selling price excl. VAT and multiply by 100 for the percentage.
Calculate the profit contribution per dish
Subtract the total ingredient costs from your selling price excl. VAT. This gives you the gross profit contribution per plate. Multiply this by the number of portions sold per week for your total profit contribution per dish.
Rank your dishes by profitability
Create a list of all your dishes sorted by total profit contribution per week. Focus on the top 5 profit makers and bottom 5 loss-making items. These insights determine your menu strategy and marketing focus.

Frequently asked questions
Should I calculate all dishes or only the most popular ones?
Start with your 10 best-selling dishes. These make up 80% of your revenue. Once you have control over those, you can expand to the rest later.
How often should I update this calculation?
At least once per quarter, or immediately after supplier price changes. Ingredient prices fluctuate a lot, so your insights can quickly become outdated.
What if my best-selling dish generates little profit?
Then you have two options: raise the price or lower ingredient costs by switching suppliers or adjusting the recipe. Removing it is rarely an option for popular items.
How do I prevent this from taking too much time?
Use a system like KitchenNmbrs that calculates automatically. Doing it manually in Excel takes hours per month, while an app shows this in seconds.
Should I also include labor costs per dish?
For an initial analysis, food cost is sufficient. Labor costs are harder to allocate per dish, unless some items require significantly more preparation time.
