A highlight box on your menu can increase sales of a profitable dish by 20-40%. But how much extra profit does that actually generate? By calculating the margin impact in advance, you can decide whether it's worth giving a dish extra attention on your menu.
What is margin impact of menu highlights?
Margin impact shows how much extra profit you earn by placing a dish more prominently. The difference between your current sales and expected sales after highlighting, multiplied by your profit margin per portion.
💡 Example:
You currently sell 15 portions of steak per week at €32.00:
- Sales price excl. VAT: €29.36
- Ingredient costs: €8.50
- Profit margin per portion: €20.86
- Current weekly profit: 15 × €20.86 = €312.90
With highlight box you expect 25% more sales = 19 portions.
Extra profit per week: 4 × €20.86 = €83.44
The formula for margin impact calculation
The basic formula is simple but powerful:
Margin impact = (New sales - Current sales) × Profit margin per portion
Where profit margin per portion = Sales price excl. VAT - Total ingredient costs
⚠️ Note:
Always calculate with the sales price excluding VAT. For restaurant food, that's your menu price divided by 1.09.
Step 1: Determine your current sales and profit margin
Look at your POS data from the past 4 weeks. Count how many portions of the dish you sell on average per week. Then calculate your exact profit margin by adding up all ingredient costs and subtracting them from your sales price excl. VAT.
- Check your POS system for exact sales figures
- Add up all ingredients: main product, garnish, sauces, oil
- Don't forget to factor in cutting loss
- Note seasonal influences (summer vs winter sales)
Step 2: Estimate the sales boost from highlighting
Research shows that menu highlights can increase sales by:
- Highlight box or frame: 15-25% more sales
- "Chef's choice" label: 20-30% more sales
- Photo with the dish: 25-40% more sales
- Combination (box + label): 30-50% more sales
💡 Conservative estimate:
Always use the lowest percentages for your calculation:
- Highlight box: calculate with 15% extra sales
- Chef's choice: calculate with 20% extra sales
- With photo: calculate with 25% extra sales
Better to be cautious than disappointed!
Step 3: Calculate the financial impact
Now you can work out what the highlight strategy will bring you:
💡 Complete calculation:
Pasta carbonara with truffle highlight box:
- Current sales: 22 portions/week
- Sales price: €24.00 incl. VAT = €22.02 excl. VAT
- Ingredient costs: €6.80 per portion
- Profit margin: €22.02 - €6.80 = €15.22 per portion
- Expected boost: 20% = 4.4 extra portions
Extra profit per week: 4.4 × €15.22 = €67
Extra profit per year: €67 × 52 = €3,484
ROI of menu changes
Don't forget to factor in the costs of the highlight strategy:
- New menu printing: €150-300
- Photography (if needed): €200-500
- Graphic design: €100-250
In the example above, you'll recoup your investment within 2-4 weeks. After that, it's pure profit.
⚠️ Watch out for cannibalization:
If guests choose the highlighted dish instead of another profitable dish, your net profit is lower. So only count new sales, not shifts from other dishes.
Digital tracking of results
Measure after 4 weeks whether your estimate was correct. Compare actual sales with your prediction. Adjust your strategy based on the results.
With a system like KitchenNmbrs, you can track your profit margins per dish exactly and quickly see which menu changes actually pay off.
How do you calculate the margin impact of menu highlighting?
Gather your current sales figures
Check your POS system for the number of portions sold of the dish over the past 4 weeks. Calculate the weekly average and note any seasonal influences.
Calculate your exact profit margin per portion
Add up all ingredient costs (including garnish and sauces) and subtract this from your sales price excluding VAT. For restaurant food, divide your menu price by 1.09.
Estimate the sales boost conservatively
Use 15% for a highlight box, 20% for chef's choice, 25% with photo. Multiply your current weekly sales by this percentage to get the number of extra portions.
Calculate the extra profit
Multiply the number of extra portions by your profit margin per portion. This gives you the extra profit per week. Multiply by 52 for the annual profit.
Deduct the costs of menu changes
Factor in the costs for new menus, photography, and design. Divide your extra annual profit by these one-time costs to determine your ROI in months.
✨ Pro tip
Never highlight more than 3 dishes at once. Too many highlights make your menu cluttered and dilute the effect. Rotate every 2-3 months to give different profitable dishes a boost.

Frequently asked questions
How much more sales does a highlight box generate?
A highlight box typically increases sales by 15-25%. Calculate conservatively with 15% to avoid disappointment. The exact impact depends on your restaurant type and position on the menu.
Should I only highlight my best-selling dishes?
No, highlight your most profitable dishes that aren't yet your top sellers. Best-sellers often need highlighting less. Focus on dishes with high margins that deserve more attention.
How do I prevent cannibalization of other dishes?
Monitor your total sales per category. If your pasta sales go up but your total main courses stay the same, you have cannibalization. Then highlight dishes from different categories or add new items.
When should I remove the highlighting again?
Once the dish becomes a stable top seller (top 3), you can remove the highlighting and use it for another dish. Most highlighting effects stabilize after 2-3 months.
Does highlighting also work for delivery menus?
Yes, but differently. On delivery platforms, photos and 'popular' labels work better than boxes. Menu order is also more important because customers scroll faster than with a physical menu.
