How to calculate the food cost of a tacos: 2026 number-crunching guide
You sell your M tacos at €7.50 but you don't actually know how much it costs to make. If that's you, you might be losing €1 on every sale without knowing it. Here is the complete method to calculate the food cost of a tacos, ingredient by ingredient.
Why calculate your food cost
Food cost is what the ingredients of a dish actually cost. It's the foundation for: setting the right selling price, measuring your margin, spotting the dishes that drag down profitability, and negotiating with suppliers.
Classic rule in fast food: your food cost should sit between 28% and 35% of the selling price. Above that you earn little. Below that, your price is likely too high for the market.
The 3-step formula
1️⃣ Break down the recipe: list every ingredient with its exact quantity (no "a bit of sauce").
2️⃣ Cost each line: (purchase price ÷ purchased quantity) × used quantity.
3️⃣ Sum everything + add 5 to 10% for waste (peelings, breakage, forgetfulness).
Food cost = Σ (ingredient costs) × 1.05 to 1.10
Worked example: a classic M tacos
Here is the real breakdown of an M tacos (25 cm wrap, 150 g of meat, 80 g of fries, 30 g of cheddar, sauces):
| Ingredient | Quantity | Unit price | Cost |
|---|---|---|---|
| Tacos wrap 25 cm | 1 pc | €0.35/pc | €0.35 |
| Ground beef | 150 g | €8.90/kg | €1.34 |
| Frozen fries | 80 g | €1.80/kg | €0.14 |
| Sliced cheddar | 30 g | €9.20/kg | €0.28 |
| Algerian sauce | 20 ml | €5.50/L | €0.11 |
| Onions | 10 g | €1.20/kg | €0.01 |
| Total ingredients | €2.23 | ||
| +10% waste | €0.22 | ||
| Final food cost | €2.45 |
Setting the selling price: the 3× rule
With a food cost of €2.45, here are the prices you can set depending on your strategy:
- →Minimum margin (food cost 35%) → price = 2.45 ÷ 0.35 = €7.00 incl. VAT
- →Target margin (food cost 30%) → price = 2.45 ÷ 0.30 = €8.15 incl. VAT
- →Premium margin (food cost 25%) → price = 2.45 ÷ 0.25 = €9.80 incl. VAT
At €7.50 on an M tacos, your food cost is 32.6% — decent but not optimal. Moving to €7.90 gives you a food cost of 31% without shocking the customer.
And the total cost beyond ingredients?
Food cost only includes ingredients. To know your real margin, you must also subtract:
- →Rent + utilities (~10-15% of revenue)
- →Labour (~25-30% of revenue)
- →Packaging (~1-3% of revenue)
- →Energy, water, consumables (~5% of revenue)
If your M tacos sells for €7.90 with €2.45 of food cost, you have €5.45 left to cover everything else. It sounds like a lot, but after the rest, your net profit per tacos is closer to €1.20–€2.
