Knowing your exact profit per portion can make or break your food truck business. Most mobile food entrepreneurs guess at their margins, but food trucks have unique cost structures that differ dramatically from traditional restaurants. You'll learn the step-by-step formula to calculate precisely what each dish puts in your pocket.
Why profit per portion matters more for food trucks
Food trucks face a completely different cost equation than brick-and-mortar restaurants. Sure, you skip the rent payments, but fuel costs, pitch fees, and accelerated equipment wear create their own financial pressures. Without precise calculations, that €12 burger might actually be costing you money.
⚠️ Note:
Food trucks typically run higher food cost percentages (35-40%) since overhead is lower. This isn't problematic if your absolute profit per portion stays healthy.
Understanding food truck cost structure
Mobile food operations juggle different expense categories than stationary restaurants:
- Variable costs: ingredients, packaging, fuel consumption
- Daily fixed costs: pitch fees, insurance premiums, vehicle depreciation
- Labor expenses: your time plus any hired help
- Operating costs: propane, maintenance, cleaning supplies
Step 1: Calculate ingredient costs per portion
Total up every component that goes into one serving, including:
- Primary ingredients (proteins, vegetables, starches)
- Accompaniments and garnishes
- Condiments and seasonings
- Packaging materials (containers, napkins, utensils)
- Cooking oils and fats
💡 Example: Pulled pork burger
- Artisan bun: €0.45
- Pulled pork (150g): €2.80
- House coleslaw: €0.35
- BBQ sauce: €0.15
- Takeaway packaging: €0.25
Total ingredient costs: €4.00
Step 2: Convert daily fixed costs to per-portion basis
Break down your fixed daily expenses by expected portion sales:
- Location fees (€50-150 daily)
- Fuel expenses (€30-60 daily)
- Vehicle depreciation (€40-80 daily)
- Insurance and permits (€20-40 daily)
💡 Example: Daily cost breakdown
- Prime pitch fee: €80
- Fuel consumption: €45
- Truck depreciation: €60
- Insurance allocation: €25
Daily total: €210
With 70 portions sold: €210 ÷ 70 = €3.00 fixed cost per portion
Step 3: Determine labor costs per portion
Your time has value - calculate it properly. Factor in a realistic hourly rate:
- Prep work: 2-3 hours
- Service period: 6-8 hours
- Cleanup: 1-2 hours
- Total daily: 9-13 hours
From years of working in professional kitchens, I've seen operators undervalue their time consistently. At €18 hourly for 11 hours = €198 labor cost. Divided by 70 portions = €2.83 per serving.
The profit per portion formula
Profit per portion = Net selling price - Ingredient costs - Fixed costs per portion - Labor costs per portion
💡 Example: Complete calculation
- Menu price: €12.00 incl. VAT = €11.01 excl. VAT
- Ingredient costs: €4.00
- Fixed cost allocation: €3.00
- Labor allocation: €2.83
Net profit per portion: €11.01 - €4.00 - €3.00 - €2.83 = €1.18
Benchmarking your profit per portion
Food truck profit targets vary by market positioning:
- Survival threshold: €1.00 per portion
- Healthy range: €1.50 - €2.50 per portion
- Premium performance: €3.00+ per portion
Remember: these figures fluctuate based on your pricing strategy and venue type. Festival locations command higher prices than regular street markets.
⚠️ Note:
Always use conservative sales projections. Slow days mean fewer portions sold, driving up your fixed cost per serving.
Streamlining calculations with digital tools
Food cost calculators help you:
- Track recipe costs with current ingredient prices
- Allocate daily fixed expenses across projected sales
- Model different scenarios (50, 70, 100 portions daily)
- Compare profitability across menu items
This visibility shows which dishes drive your bottom line and guides menu optimization decisions.
How do you calculate profit per portion? (step by step)
Calculate ingredient costs including packaging
Add up all costs: main ingredients, side dishes, sauces, packaging and oil. Don't forget anything that goes into or with the portion.
Divide daily fixed costs across expected portions
Sum up pitch fees, fuel, depreciation and insurance. Divide this by the number of portions you expect to sell that day.
Calculate labor costs per portion
Multiply your working hours (prep + sales + cleaning) by a realistic hourly wage. Divide this by the number of sold portions.
Subtract all costs from your selling price excl. VAT
Selling price excl. VAT minus ingredient costs minus fixed costs per portion minus labor costs per portion = profit per portion.
✨ Pro tip
Track profit margins across different locations for 30 days minimum. That expensive €150 pitch fee often pays for itself through higher sales volume and premium pricing opportunities.

Frequently asked questions
Should I include my own labor in the calculation?
Absolutely - your time has monetary value. Calculate at minimum €15-20 per hour, or you won't know if the business actually generates profit beyond covering expenses.
How do I handle fluctuating daily sales?
Model three scenarios: slow day (50 portions), typical day (70 portions), and busy day (100 portions). This shows your profit range and helps set realistic expectations.
What if my profit per portion falls short?
You have three levers: increase prices, reduce ingredient costs, or secure cheaper pitch locations. Start by analyzing whether your pricing reflects your value proposition.
