Most food truck owners think popular dishes automatically mean profit - but that's dead wrong. You could be selling 100 portions a day and still bleeding money if you haven't done the math. Here's how to determine if that new menu item will actually make you money.
Why cost price calculation is crucial for food trucks
With a food truck, you've got limited space, limited inventory, and often just one chance to get it right. A dish that's too expensive to source can ruin your entire day.
⚠️ Note:
Food trucks often have higher food costs than restaurants (30-40%) due to smaller purchase volumes and packaging costs. Factor this in.
The food truck cost price formula
For food trucks, you use the same basic formula as restaurants, but with extra considerations:
Food cost % = (Total ingredient costs + packaging) / Selling price excl. VAT × 100
- All ingredients (including spices, oil, sauces)
- Packaging costs (boxes, bags, cutlery)
- Selling price excluding 9% VAT
💡 Example: Gourmet burger
You want to introduce a premium burger for €12.50 (incl. 9% VAT):
- Beef (150g): €2.40
- Brioche bun: €0.85
- Cheese, lettuce, tomato: €0.65
- Special sauce: €0.35
- Fries (200g): €0.45
- Packaging: €0.40
Total: €5.10
Selling price excl. VAT: €12.50 / 1.09 = €11.47
Food cost: (€5.10 / €11.47) × 100 = 44.5%
Calculate break-even point
Besides food cost, you need to know how much you must sell minimum to cover your fixed costs. One of the most common blind spots in kitchen management is forgetting to account for these daily expenses:
- Pitch rental per day
- Truck fuel
- Labor costs (yourself + any staff)
- Insurance and permits (per day)
💡 Example: Daily costs
Fixed costs per day:
- Pitch: €80
- Fuel: €25
- Labor (8 hours × €15): €120
- Other costs: €25
Total per day: €250
At €11.47 - €5.10 = €6.37 margin per burger
Break-even: €250 / €6.37 = 40 burgers per day
Competitive analysis and price positioning
Check what comparable food trucks in your area charge for similar dishes. Your price must be competitive, but still cover your costs.
⚠️ Note:
Food truck customers are more price-sensitive than restaurant diners. A €2 difference can drastically affect your sales.
Seasons and weather dependency
Food trucks are weather-dependent. Factor in lower sales on rainy days and during winter months:
- Summer: 100% of calculated sales
- Spring/Fall: 70-80% of calculated sales
- Winter: 50-60% of calculated sales
Adjust your break-even calculation accordingly to have realistic expectations.
💡 Example: Seasonal adjustment
You need 40 burgers per day for break-even in summer.
In winter (60% sales): you sell an average of 24 burgers per day.
Shortfall: €250 - (24 × €6.37) = €97 per day
This means you need to make extra margin in summer to bridge the winter.
Digital tools for cost price calculation
Manual calculations are time-consuming and error-prone. An app like KitchenNmbrs helps food truck entrepreneurs quickly and accurately calculate cost prices, including packaging costs and VAT calculations.
With digital recipe registration, you immediately see whether a new dish is financially viable, without having to do the math yourself in Excel.
How do you calculate whether a new dish is financially viable? (step by step)
List all ingredients and costs
Make a complete list of all ingredients including quantities per portion. Don't forget spices, oil, sauces, and packaging materials. Use current purchase prices from your suppliers.
Calculate the total cost price per portion
Add up all ingredient costs and packaging costs. This is your total cost price per dish. Check that you haven't forgotten anything by going through the list once more.
Determine your selling price and calculate food cost
Check what competitors charge for similar dishes. Calculate your food cost: (cost price / selling price excl. VAT) × 100. For food trucks, 30-40% is normal.
Calculate how much you need to sell for break-even
Subtract your cost price from your selling price (excl. VAT) for your margin per dish. Divide your daily fixed costs by this margin to know how many portions you must sell minimum.
Test with a small batch
Start with a limited amount of ingredients for 20-30 portions. Measure how much you sell and how customers react. Adjust the price or recipe based on this test.
✨ Pro tip
Test any new dish for exactly 3 days during your busiest lunch hours before committing. If it doesn't hit 15+ orders per day in that prime window, it won't survive slower periods.
Calculate this yourself?
In the KitchenNmbrs app you can do this in just a few clicks. 7 days free, no credit card.

Frequently asked questions
What is an acceptable food cost for a food truck?
For food trucks, an acceptable food cost is between 30-40%, higher than restaurants due to smaller purchase volumes and packaging costs. Under 35% is good, above 45% becomes difficult.
Should I include packaging costs in my cost price?
Yes, absolutely. Packaging costs (boxes, bags, cutlery) are a direct part of your cost price. For food trucks, this can be €0.30-€0.60 per dish, depending on the type of packaging.
How often should I update my cost prices?
Check your cost prices at least monthly, especially for seasonal products. Suppliers regularly raise prices and that can significantly affect your margin without you noticing.
What if my break-even is too high?
If you need to sell more than 60-80 portions per day for break-even, the dish is probably not viable. Lower your cost price by using cheaper ingredients or raise your selling price.
Should I account for seasons?
Yes, food trucks are heavily weather-dependent. Factor in 50-60% lower sales during winter months. Your summer margin must be large enough to cover slow periods.
How do I handle prep time costs for complex dishes?
Calculate prep time as labor cost per portion. If a dish takes 2 hours prep for 20 portions, that's 6 minutes per portion at your hourly wage rate.
What's the minimum margin I need per dish to stay profitable?
Aim for at least €4-6 gross margin per dish after food costs. This covers your fixed costs, labor, and leaves room for profit on typical daily sales volumes.
