I'll admit something that surprised me after analyzing hundreds of food truck operations: beverages can make or break your profitability. On a food truck where every square meter counts, knowing how much extra margin beverages generate isn't just helpful—it's essential. The difference between success and struggle often comes down to understanding these numbers.
The difference between beverage and food cost price
The cost price of beverages is dramatically lower than food. While dishes typically hit 28-35% food cost, beverages usually fall between 15-25%.
💡 Example:
Comparison burger vs. soft drink:
- Burger: €3.50 cost on €12.00 sale = 29% cost price
- Cola (0.33l): €0.45 cost on €2.50 sale = 18% cost price
Difference in margin: 11 percentage points!
Calculate your beverage margins correctly
For beverages, you calculate the same way as food: cost price divided by sale price excluding VAT, times 100. Remember that beverages have 9% VAT consumed with the meal.
⚠️ Note:
Alcoholic beverages have 21% VAT. Always calculate excluding VAT for your margin calculation.
The impact on your total profit
The difference becomes visible fast once you look at annual impact. Every additional beverage sold increases your average margin per customer. Based on real restaurant P&L data, this effect compounds quickly across thousands of transactions.
💡 Example annual calculation:
Food truck with 100 customers per day, 5 days per week:
- Without beverages: average margin 71% (29% cost price)
- With 1 beverage per customer: average margin rises to 76%
- At €400,000 annual revenue: €20,000 extra profit
Practical tips for your food truck
On a food truck you've got limited space, so choose wisely which beverages you sell. Focus on beverages with high turnover and low cost price.
- Soft drinks: High margin, long shelf life, popular
- Water: Lowest cost price, always in demand
- Coffee/tea: Very low cost price, high perceived value
- Alcoholic beverages: Only if you have a license
Measure and compare your results
Keep track of what percentage of your customers also buy a beverage. This is called your "attach rate" and determines how much extra margin you realize.
💡 Attach rate calculation:
Number of beverages sold ÷ number of customers × 100
- 50 beverages with 100 customers = 50% attach rate
- Every 10% improvement = significantly more margin
A food cost calculator helps you track both your food and beverage cost price, so you can see exactly which combinations are most profitable.
How do you calculate the extra margin from beverages? (step by step)
Calculate your cost price per beverage type
Add up all costs: purchase, packaging, ice cubes. Divide this by your sale price excluding VAT and multiply by 100 for the percentage.
Compare with your average food cost
Subtract your beverage cost price from your average dish cost price. This difference in percentage points is your extra margin per beverage sold.
Calculate the impact on an annual basis
Multiply the margin difference by your number of customers per year and your average beverage price. This shows you how much extra profit beverages generate.
✨ Pro tip
Track your beverage attach rate during your busiest 3-hour lunch rush for 2 weeks straight. You'll discover which drinks customers actually crave versus which ones just sit there taking up precious cooler space.

Frequently asked questions
Which beverages have the highest margin on a food truck?
Coffee, tea and water have the lowest cost price (often under 15%). Soft drinks are around 18-22%. Freshly squeezed juices have higher cost price but also higher sale price.
Should I include VAT in my margin calculation for beverages?
No, always calculate excluding VAT. Beverages consumed with the meal have 9% VAT, alcoholic beverages 21%. Divide your purchase price by the sale price excluding VAT.
How much space should I reserve for beverages on my food truck?
About 20-30% of your cooling space. Beverages deliver more margin per square meter than most ingredients, so it's a smart investment in space.
What is a good attach rate for beverages on food trucks?
An attach rate of 60-80% is easily achievable. On warm days or with spicy dishes this can be even higher. Measure this weekly to see trends.
