Promotional amuse-bouches can drive significant revenue growth for your featured dishes. Calculating margins gets tricky when you're giving away food for free. Think of your amuse cost as a marketing investment that pays dividends through increased sales of the dish you're highlighting.
The two cost items of a promotional amuse
An amuse that promotes a dish involves two distinct cost items that need separate calculations.
💡 Example:
You serve a mini-portion of your signature spaghetti carbonara as an amuse (20 grams pasta, 10 grams guanciale, quarter egg):
- Pasta: €0.12
- Guanciale: €0.45
- Egg: €0.08
- Parmesan: €0.15
- Pepper: €0.02
Cost price amuse: €0.82
Calculate the break-even conversion
Finding profitability means calculating what percentage of guests must order the full dish to offset your amuse costs.
Formula: Break-even conversion = (Cost price amuse / Profit per full dish) × 100
💡 Example calculation:
Your spaghetti carbonara:
- Selling price: €18.50 incl. VAT = €16.97 excl. VAT
- Ingredient costs full dish: €5.10
- Profit per dish: €16.97 - €5.10 = €11.87
- Cost price amuse: €0.82
Break-even: (€0.82 / €11.87) × 100 = 6.9%
If 7 out of 100 guests order the full dish after tasting the amuse, you break even on costs.
Measure the actual conversion
Track how many guests order the promoted dish after trying the amuse. This shows if your investment actually delivers returns.
- Count daily: number of amuses served vs. number of full dishes sold
- Calculate: conversion percentage = (dishes sold / amuses served) × 100
- Compare with your break-even percentage
⚠️ Note:
Only count guests who order the dish AFTER trying the amuse. Guests who'd already ordered before the amuse don't count toward conversion.
Include additional benefits in the calculation
From analyzing actual purchasing data across different restaurant types, successful amuses often deliver benefits beyond direct sales of the promoted dish:
- Higher guest experience: satisfied guests return more often
- Word-of-mouth marketing: guests tell others about the experience
- Higher average bill: guests may order more because they're in a good mood
- Seasonal promotion: you can quickly test if a new dish will be a hit
💡 Real-world example:
Restaurant De Smaak serves a mini-risotto as an amuse (cost price €0.95). Result after 1 month:
- 600 amuses served
- 78 full risottos sold additionally (13% conversion)
- Break-even was 8%
- Extra profit: 78 × €12.50 = €975
- Cost of amuses: 600 × €0.95 = €570
Net result: +€405 extra profit
When a promotional amuse doesn't pay off
Stop serving the amuse if conversion consistently stays below your break-even percentage. Then it's just costing you money without any return.
Possible causes of low conversion:
- The amuse portion is too large (guests are already satisfied)
- The dish is too expensive for your target audience
- The taste of the amuse differs too much from the full dish
- Timing is wrong (amuse served too late in the meal)
How do you calculate the margin of a promotional amuse?
Calculate the cost price of your amuse
Add up all the ingredients that go into the mini-portion. Calculate what each amount costs based on your purchase prices. Don't forget garnish, oil, or other small ingredients.
Determine the profit per full dish
Subtract the ingredient costs from your selling price (excl. VAT). This is the profit per dish you need to 'recoup' with the amuse. For example: €16.97 - €5.10 = €11.87 profit.
Calculate your break-even conversion
Divide the cost price of the amuse by the profit per full dish and multiply by 100. This percentage of guests must order the dish to break even. Anything above that is pure profit.
✨ Pro tip
Track your amuse conversions for exactly 21 days during peak season, then compare against your break-even rate. Any conversion above 9% typically signals a profitable promotional strategy that's worth continuing.

Frequently asked questions
Should I include the amuse costs in my food cost?
No, treat the amuse as a marketing cost, not as food cost. It's an investment to sell more of the promoted dish, similar to advertising expenses.
What is a realistic conversion rate for a promotional amuse?
This varies by restaurant and dish, but 10-20% conversion is common. If you're below 5%, the amuse probably isn't effective enough.
Can I promote multiple dishes with one amuse?
That makes the calculation more complex. You'd need to track which dish guests choose and calculate the conversion rate per dish separately. It's better to focus on one dish for clear results.
How long should I keep a promotional amuse?
Test for at least 2-4 weeks to get reliable figures. If the conversion is still below your break-even after a month, stop it or adjust your strategy.
Should I calculate seasonal ingredients differently?
Yes, update your cost price regularly as ingredient prices change. An amuse that's profitable in one season can become unprofitable in another due to more expensive ingredients.
What if my amuse costs more than my break-even allows?
Either reduce portion size, simplify ingredients, or choose a dish with higher profit margins to promote. Some expensive ingredients just don't work for promotional amuses.
How do I account for labor costs in my amuse calculation?
If your amuse requires significant extra prep time, factor in labor costs at your kitchen hourly rate. Add this to your ingredient cost before calculating break-even conversion.
