Visual elements on your menu can significantly boost sales of profitable dishes. Think photos, icons or special frames around certain dishes. But what does such an investment really return? In this article you'll learn step-by-step how to calculate what the margin impact is of visual adjustments to your best performing dishes.
Why visual elements work for profitable dishes
Your menu is a sales tool. Studies show that dishes with visual attention are ordered 20-30% more often. But not every dish deserves this attention - only your profitable top performers.
💡 Example:
Your ribeye steak has a food cost of 28% and is sold 80 times per month. After adding a photo, this increases to 104 orders (+30%).
- Selling price: €32.00 incl. VAT (€29.36 excl.)
- Profit per portion: €29.36 - €8.22 (ingredients) = €21.14
- Extra sales: 24 portions per month
Extra profit per month: €507.36
The basic calculation: margin impact per dish
For each profitable dish you add visual attention to, calculate the potential impact with this formula:
Extra profit = (Selling price excl. VAT - Ingredient costs) × Current sales × Expected increase %
⚠️ Note:
Always calculate with the selling price excluding VAT. The price on your menu card includes 9% VAT for food.
Costs of visual elements
Different options have different cost structures:
- Professional menu card with photos: €800-1500 one-time
- Menu icons and design: €300-600 one-time
- Digital menu cards with photos: €200-400 + €30-50/month
- Special menu inserts: €150-300 per reprint
ROI calculation over 12 months
To determine if the investment pays off, calculate the payback period:
💡 Example calculation:
Menu card investment with photos: €1200
- 3 profitable dishes receive visual attention
- Average extra profit per dish: €400/month
- Total extra profit: €1200/month
Payback period: 1 month
Which dishes to choose for visual attention
Focus on dishes that meet these criteria:
- Food cost below 30%: Enough margin to make growth profitable
- Minimum 40 sales per month: Sufficient volume for impact
- Photogenic: Looks attractive on camera
- No seasonal ingredients: Remains available year-round
⚠️ Note:
Avoid visual attention for dishes with a food cost above 35%. More sales of loss-making dishes will cost you money.
Measuring the actual effect
After implementation, it's crucial to measure the real effect:
- Compare sales figures 3 months before vs. 3 months after
- Account for seasonal influences
- Also measure the effect on other dishes (cannibalization)
- Check that food cost remains stable at higher volumes
KitchenNmbrs and menu engineering
With a system like KitchenNmbrs you can immediately see which dishes are the best candidates for visual attention. You can analyze profitability and sales frequency per dish, so you make data-driven decisions about your menu investments.
How do you calculate the margin impact? (step by step)
Select your most profitable dishes
Choose 3-5 dishes with a food cost below 30% and minimum 40 sales per month. This combination gives you the best chance of successful ROI on visual investments.
Calculate current profit per dish per month
Multiply (selling price excl. VAT - ingredient costs) by the number of sales per month. This gives you the baseline profit against which you can measure the impact.
Estimate sales impact and calculate extra profit
Assume a conservative increase of 20-25%. Multiply your current monthly profit per dish by this percentage to calculate the potential extra profit.
Compare with investment and calculate payback period
Divide the total investment (menu card, photos, design) by your expected extra monthly profit. A payback period of 2-4 months is healthy for this type of investment.
✨ Pro tip
Start with one profitable dish and test for 3 months. Measure the effect thoroughly before adding more visual elements. This way you build data-driven evidence for further investments.

Frequently asked questions
How much sales increase can I expect from visual elements?
Studies show 20-30% sales increase for dishes with visual attention. Be conservative and calculate with 20% to avoid disappointment. Measure the actual effect after 3 months.
Should I visually emphasize all profitable dishes?
No, choose a maximum of 3-5 dishes. Too much visual attention dilutes the effect. Focus on your absolute top performers with the best combination of profitability and sales volume.
What if my food cost increases due to higher sales?
With larger purchases you often get better prices from suppliers. Check after 2 months whether your food cost remains stable. If not, renegotiate your purchase prices or adjust your selling price.
How long does it take before I see results?
Usually you'll see a difference in orders within 2-4 weeks. However, only measure definitively after 3 months, as guests need time to discover the new menu.
What if other dishes sell less?
This is called cannibalization and is normal. As long as your total profit increases, it's positive. Measure the impact on your entire menu, not just the dishes with visual attention.
