A café owner discovers their popular €12 yogurt bowl actually costs €5.20 to make – turning their expected 30% food cost into a devastating 43%. Those forgotten drizzles of honey and handfuls of premium nuts add up fast. Calculating accurate margins for this deceptively simple dish requires tracking every ingredient, no matter how small.
Gather all ingredients and prices
For an accurate margin calculation, you need to include every single ingredient, even those tiny amounts that seem insignificant:
- Yogurt (Greek or plain)
- Granola or muesli
- Fresh fruit (seasonal)
- Honey or maple syrup
- Optional: nuts, seeds, coconut
- Garnish: mint leaves, extra fruit
💡 Example ingredient list:
For 1 serving yogurt bowl (250ml yogurt base):
- Greek yogurt 250ml: €1.20
- Granola 40g: €0.65
- Mixed red fruit 80g: €1.80
- Honey 15ml: €0.25
- Almonds 10g: €0.30
- Mint leaves: €0.05
Total ingredient costs: €4.25
Calculate the cost price per serving
Add up all ingredient costs and double-check that your portion size matches what actually gets served. Many kitchens unknowingly give larger portions than calculated – from tracking this across dozens of restaurants, portion creep is the #1 reason margins shrink over time.
⚠️ Note:
Fresh fruit prices swing wildly by season. Strawberries cost €8/kg in January, €3/kg in June. Update your cost prices monthly or you'll get burned.
Determine your desired margin percentage
For breakfast and brunch dishes, typical margins are:
- Food cost 25-35%: Standard for breakfast dishes
- Food cost 20-30%: With high labor input (freshly prepared)
- Food cost 30-40%: With premium or organic ingredients
A 30% food cost means 70% of your selling price covers staff, rent and profit. Don't go higher than 40% unless you've got solid reasons.
Calculate the selling price
Use this formula: Minimum selling price = Ingredient costs ÷ (Food cost % ÷ 100)
💡 Example calculation:
Ingredient costs: €4.25
Target food cost: 30%
- Minimum price excl. VAT: €4.25 ÷ 0.30 = €14.17
- Price incl. 9% VAT: €14.17 × 1.09 = €15.44
- Menu price: €15.50 (rounded)
Actual food cost: €4.25 ÷ €14.22 = 29.9%
Check seasonal fluctuations
Fruit and nut prices vary dramatically by season. Plan different versions of your dish:
- Summer: Seasonal fruit (cheaper), lower food cost possible
- Winter: Frozen or imported fruit, higher cost price
- Alternative: Fixed price, varying fruit types per season
💡 Seasonal strategy:
Calculate 3 scenarios for the same dish:
- Summer (seasonal fruit): food cost 28%
- Winter (expensive fruit): food cost 35%
- Average: food cost 31%
Price your dish based on the average, and you'll stay profitable year-round.
Monitor your actual margin
Check monthly if your calculated margin matches reality. Food cost tracking tools can help automate these calculations. Pay attention to:
- Portion size in the kitchen vs. calculation
- Waste from fresh fruit
- Supplier price changes
- Seasonal effects on purchase prices
How do you calculate the margin on yogurt with granola? (step by step)
Make a complete ingredient list
Write down all ingredients including small quantities like honey, nuts and garnish. Don't forget anything, not even the mint leaves or extra drizzle.
Calculate the exact quantities per serving
Weigh or measure exactly how much of each ingredient you use. Check this in the kitchen - often practice differs from your estimate.
Add up all ingredient costs
Multiply each quantity by the purchase price per unit. This gives you the total cost price per serving.
Determine your desired food cost percentage
For breakfast dishes, 25-35% is typical. With premium ingredients this can be higher, with simple dishes lower.
Calculate your minimum selling price
Divide your ingredient costs by your desired food cost percentage. Then add 9% VAT for your menu price.
✨ Pro tip
Weigh your actual yogurt bowl portions every 2 weeks against your calculated recipe. An extra 10g of granola per bowl costs you €340 annually at 80 servings per week.

Frequently asked questions
Should I include VAT in my margin calculation?
Always calculate first excl. VAT and then add 9% VAT for the menu price. If you calculate with VAT included, your margin will appear higher than it actually is.
How often should I update my cost price for seasonal fruit?
Check your fruit prices monthly and update your calculation accordingly. You can offset large fluctuations by offering different fruit types per season.
What is a realistic food cost for yogurt bowls?
Between 25-35% is typical for breakfast dishes. With organic or premium ingredients this can go up to 40%, but then watch your overall margin carefully.
How do I factor waste into my cost price?
Add 5-10% waste to your ingredient costs for fresh fruit. Better yet: improve your inventory rotation to minimize waste in the first place.
Can I charge different prices per season?
You can, but it confuses customers. Better to calculate one price based on average annual costs – then you'll always be covered.
What's the biggest mistake with yogurt bowl costing?
Underestimating garnish costs and portion creep. That extra drizzle of honey and handful of nuts can push your food cost from 30% to 45% without you realizing it.
