A meatball with gravy and mashed potatoes appears straightforward until you start tallying every ingredient cost. Most restaurants overlook the butter, cream, and seasonings that silently erode profit margins. Here's how to calculate the precise food cost for this comfort food staple.
Gather all ingredients and prices
For an accurate food cost calculation, you need the purchase prices of every ingredient that goes on the plate. Even the smallest amounts count.
💡 Example ingredient list:
- Ground beef: €8.50/kg
- Potatoes: €1.20/kg
- Cream (35%): €2.80/liter
- Butter: €12.00/kg
- Onion: €1.50/kg
- Bouillon cube: €0.08/piece
- Flour: €1.10/kg
- Spices and salt: €0.05/portion
Don't overlook the 'invisible' ingredients like searing oil, pepper, salt and fresh herbs. These costs appear minimal but accumulate rapidly at scale.
Calculate the quantity per portion
Measure or weigh exactly how much of each ingredient you use for one portion. Skip the guesswork and use a kitchen scale.
💡 Example portion quantities:
- Ground beef: 150g
- Potatoes (for puree): 250g
- Cream: 30ml
- Butter: 15g
- Onion: 25g
- Bouillon cube: 0.5 piece
- Flour (for gravy): 5g
Remember that potatoes have cutting loss from peeling. Account for 15-20% loss, so for 250g peeled potatoes you'll need 300g unpeeled.
Calculate the costs per portion
Multiply the quantity per portion by the purchase price per kilogram or liter. Use this formula: Portion cost = (Quantity in grams ÷ 1000) × Price per kg
💡 Example calculation:
- Ground beef: (150g ÷ 1000) × €8.50 = €1.28
- Potatoes: (300g ÷ 1000) × €1.20 = €0.36
- Cream: (30ml ÷ 1000) × €2.80 = €0.08
- Butter: (15g ÷ 1000) × €12.00 = €0.18
- Onion: (25g ÷ 1000) × €1.50 = €0.04
- Bouillon: 0.5 × €0.08 = €0.04
- Flour: (5g ÷ 1000) × €1.10 = €0.01
- Spices: €0.05
Total food cost: €2.04 per portion
⚠️ Note:
Always use the actual purchase prices from your supplier. Prices can vary significantly by region and season.
Calculate your food cost percentage
From analyzing actual purchasing data across different restaurant types, divide the total food cost by your selling price excluding VAT. Most restaurants target a food cost of 28-35%.
💡 Food cost calculation:
Menu price: €16.50 (incl. 9% VAT)
- Selling price excl. VAT: €16.50 ÷ 1.09 = €15.14
- Food cost: €2.04
- Food cost percentage: (€2.04 ÷ €15.14) × 100 = 13.5%
This represents a healthy margin. You've got €13.10 remaining for labor, overhead and profit.
Check and update regularly
Suppliers regularly increase their prices. Review your food costs monthly, particularly for your top-selling dishes.
- Update prices with new supplier invoices
- Weigh portions periodically to verify consistent portioning
- Monitor seasonal price fluctuations (potatoes cost more in spring)
Systems like KitchenNmbrs can automate these calculations. Update your purchase prices once and all recipes recalculate automatically.
How do you calculate the food cost of a meatball? (step by step)
Create a complete ingredient list
Note every ingredient that goes into the dish, including oil, salt, spices and garnish. Look up the current purchase prices from your latest invoices.
Weigh all portion quantities
Measure exactly how many grams or milliliters you use of each ingredient per portion. Don't estimate, but weigh with a kitchen scale for accuracy.
Calculate the costs per ingredient
Multiply the quantity per portion by the purchase price. Use the formula: (grams ÷ 1000) × price per kg for each ingredient.
Add up all costs
Sum all individual ingredient costs to get the total food cost per portion. This is your basis for profitability calculations.
Calculate your food cost percentage
Divide the total food cost by your selling price excluding VAT and multiply by 100. Aim for 28-35% for healthy margins.
✨ Pro tip
Recalculate your meatball dish cost every 6 weeks during peak season when beef and potato prices fluctuate most. This single dish often represents 12-15% of total sales volume.

Frequently asked questions
Should I include VAT in my food cost calculation?
No, always calculate using the selling price excluding VAT. For restaurants that's your menu price divided by 1.09 (at 9% VAT). Otherwise your food cost will appear artificially lower.
What if my food cost exceeds 35%?
You're likely losing money on that dish. Reduce the portion size, substitute cheaper ingredients, or increase your selling price until the food cost drops below 35%. Quick action prevents ongoing losses.
Should I account for cutting loss with potatoes?
Absolutely - account for 15-20% loss from peeling and removing eyes. For 250g peeled potatoes you need 300g unpeeled, which increases your actual cost per usable gram.
How precise should I be with small ingredients like salt?
Calculate spices and salt as a flat rate of €0.05-0.10 per portion. The exact amount matters less than including them completely, since costs accumulate at high volumes.
