How many dishes should your food truck actually serve to maximize profit? Food trucks with 20+ dishes often have higher food costs and more waste than trucks with 6-8 dishes. You'll discover how to calculate the optimal menu size based on margins and operational efficiency.
Why menu size is crucial for food trucks
Food trucks face unique constraints: limited storage, compact kitchen space, and the need for lightning-fast service. A bloated menu creates these problems:
- Higher inventory costs (more ingredients, more spoilage)
- Longer prep time per order
- More complexity in purchasing and prep work
- Lower ingredient turnover rate
Your goal: maximize profit per square meter of kitchen space.
💡 Example:
Food truck A: 15 dishes, average food cost 38%
Food truck B: 7 dishes, average food cost 28%
At €2000 revenue per day, this creates a €200 daily profit difference.
Calculate your current situation
You need these figures for every calculation:
- Food cost per dish (ingredients ÷ selling price excl. VAT × 100)
- Sales volume per dish per day
- Inventory costs per dish (what you need to keep in stock minimum)
- Prep time per dish
Organize your current dishes in a matrix:
💡 Example matrix:
- Top performers: High sales + low food cost (classic burger: 45×/day, 25% food cost)
- Profit makers: Low sales + low food cost (pulled pork: 12×/day, 22% food cost)
- Popular but expensive: High sales + high food cost (fish & chips: 30×/day, 42% food cost)
- Losers: Low sales + high food cost (veggie wrap: 5×/day, 45% food cost)
The ideal menu size formula
For food trucks, the 80/20 rule applies: 80% of your revenue comes from 20% of your menu. But operationally, the 70/30 rule works better:
Ideal number of dishes = (Daily revenue ÷ €15) ÷ 10
This gives a rough estimate. Refine it with these parameters:
- Minimum 4 dishes (otherwise too little choice)
- Maximum 12 dishes (otherwise too complex)
- Sweet spot for most food trucks: 6-8 dishes
💡 Example calculation:
Food truck with €1800 daily revenue:
(€1800 ÷ €15) ÷ 10 = 12 dishes
But: limit to 8 dishes for better operational efficiency.
Optimize based on margins
Use these criteria to select dishes:
Keep dishes that:
- Have food cost below 30%
- Sell at least 15× per day
- Share ingredients with other dishes
- Can be prepared within 3 minutes
Consider removing:
- Food cost above 40%
- Sell fewer than 8× per day
- Unique ingredients that spoil quickly
- Prep time longer than 5 minutes
⚠️ Heads up:
Removing dishes can disappoint customers. First test by marking dishes as 'temporarily unavailable' and measure the impact on total sales.
Maximize ingredient overlap
Food trucks have limited refrigeration space. Based on real restaurant P&L data, trucks with high ingredient overlap show 15-22% better margins. Choose dishes that share ingredients:
💡 Smart menu example:
- Base: Burger, chicken, bacon, cheese, lettuce, tomato, onion
- Dishes: Classic burger, bacon burger, chicken burger, chicken wrap, bacon salad, loaded fries
- Result: 6 dishes with only 8 main ingredients
Test and measure your new menu size
Implement your optimized menu and measure over 4 weeks:
- Average food cost (should decrease)
- Average order time (should decrease)
- Waste per day (should decrease)
- Revenue per day (may decrease max 10%)
If your revenue drops more than 10%, add 1-2 popular dishes back.
Tools for food truck optimization
A food cost calculator helps with:
- Automatic food cost calculation per dish
- Ingredient overlap analysis
- Daily margin tracking
- Recipe management for consistent results
Perfect for food truck entrepreneurs who want quick insights without Excel hassle.
How do you calculate the ideal menu size? (step by step)
Analyze your current menu
Calculate the food cost percentage for each dish and count how many you sell per day. Rank them from high to low based on profit per dish (sales volume × margin per item).
Identify your top performers
Select dishes with food cost below 30% AND at least 15 sales per day. These form the core of your new menu. Add 1-2 unique signature dishes for differentiation.
Optimize for ingredient overlap
Choose dishes that maximize shared ingredients to reduce inventory costs. Aim for 80% ingredient overlap between your dishes. Test the new menu for 4 weeks and measure food cost and revenue impact.
✨ Pro tip
Track your 'profit per minute of prep time' for each dish over 30 days. A dish with 30% food cost that takes 2 minutes beats a dish with 25% food cost that takes 4 minutes.

Frequently asked questions
How many dishes should a food truck have maximum?
For most food trucks, 6-8 dishes is optimal. More than 12 dishes often leads to higher food costs and longer wait times. Fewer than 4 dishes offers too little choice for customers.
What if customers miss their favorite dish after removing it?
First test by marking dishes as 'sold out'. Measure the impact on total revenue. If revenue drops more than 10%, consider bringing the dish back or replacing it with a similar alternative.
Can I just remove the least sold dishes?
Not necessarily. Look at profit per dish (sales × margin), not just sales volume. A dish that sells little but has high margin can be more profitable than a popular dish with low margin.
What is good food cost for food truck dishes?
For food trucks, 25-32% food cost is standard. Due to limited space and higher operational costs, you can accept slightly higher food cost than in restaurants. Aim for an average below 30%.
