Last month, a food truck owner thought he made €2,000 profit until he realized he forgot about the €650 VAT payment. This common mistake leaves many food truck entrepreneurs confused about their actual earnings. Understanding your true net margin after VAT prevents these costly oversights.
What is net margin and why is it important?
Net margin shows the percentage of revenue that stays in your pocket after covering all expenses, including VAT obligations. Food truck operators need this figure because cash transactions and mobile operations make it easy to lose sight of true profitability.
💡 Example:
Your food truck made €8.000 in revenue this month:
- Revenue incl. VAT: €8.000
- VAT (9%): €661
- Revenue excl. VAT: €7.339
- Total costs: €6.200
- Profit before VAT: €1.139
Net margin: (€1.139 / €8.000) × 100 = 14.2%
The correct formula for food truck net margin
Most entrepreneurs mess this up by ignoring VAT or missing hidden costs. Here's the formula that actually works:
Net margin % = ((Revenue excl. VAT - All costs) / Revenue incl. VAT) × 100
You divide by revenue including VAT because that's what customers actually pay you.
Which costs should you include?
Food trucks carry more expense categories than brick-and-mortar restaurants:
- Food cost: All ingredients and packaging materials
- Fuel: Diesel for truck movement and generator power
- Stand fees: Market spaces and event permits
- Insurance: Vehicle, liability, and inventory coverage
- Maintenance: Truck servicing, equipment repairs, MOT testing
- Permits: Trading licenses and food safety certifications
- Phone and internet: Card payment systems and communication
⚠️ Attention:
Include depreciation on your truck and equipment. Even if you don't write monthly checks, these assets lose value and impact your real profitability.
Processing VAT correctly
Food truck operators typically register for VAT since takeaway food qualifies for the reduced 9% rate. Calculate it this way:
💡 VAT calculation:
Revenue of €5.000 incl. VAT means:
- Revenue excl. VAT: €5.000 / 1.09 = €4.587
- VAT owed: €5.000 - €4.587 = €413
- You must pay this €413 to the Tax Authority
What is a good net margin for food trucks?
Based on real restaurant P&L data, food trucks typically achieve higher margins than fixed locations due to lower labor and rent costs. Target these ranges:
- 10-15%: Solid performance for most food truck concepts
- 15-20%: Excellent results, especially for established routes
- Below 10%: Problematic - review your pricing and cost structure
- Above 20%: Outstanding performance, or you're overlooking expenses
Monthly check routine
Track these metrics monthly to maintain healthy margins:
- Total revenue and average transaction value
- Food cost percentage (target under 35%)
- Daily fuel consumption costs
- Operating days versus daily revenue averages
💡 Practical example:
Food truck 'The Best Burger' in March:
- 22 working days, average €320 per day
- Total revenue: €7.040 incl. VAT
- Revenue excl. VAT: €6.459
- Food cost: €2.200 (34%)
- Other costs: €3.100
- Profit: €1.159
Net margin: (€1.159 / €7.040) × 100 = 16.5%
How do you calculate your net margin? (step by step)
Gather all revenue and costs
Add up all income for the month (including VAT). Make a list of all expenses: ingredients, fuel, stand fees, insurance, maintenance and other costs.
Calculate revenue excluding VAT
Divide your total revenue by 1.09 to get the revenue excluding 9% VAT. This is your actual sales value without the VAT you need to pay.
Subtract all costs and calculate percentage
Subtract all costs from your revenue excluding VAT. Divide the result by your total revenue including VAT and multiply by 100 to get your net margin percentage.
✨ Pro tip
Track your net margin weekly for the first 8 weeks of operation to identify patterns quickly. You'll discover which locations and weather conditions generate the highest profits versus operational costs.

Frequently asked questions
Should I include VAT in my net margin calculation?
Yes, VAT directly impacts your cash flow since you collect it from customers but owe it to tax authorities. Calculate profit using revenue excluding VAT, but divide by total revenue including VAT for the percentage.
What if I make a loss on some days?
Daily losses are normal due to weather, location changes, and seasonal fluctuations. Focus on monthly averages instead. If you're losing money more than 5 days monthly, examine your fixed costs and pricing strategy.
How often should I check my net margin?
Review your complete net margin monthly and monitor food cost percentages weekly. This frequency lets you spot problems early and make adjustments before they damage your bottom line.
Is 10% net margin enough for a food truck?
10% represents the minimum for sustainable operations. Aim for 15% or higher to build reserves for equipment repairs and seasonal downturns. Anything below 10% leaves you vulnerable to unexpected expenses.
Which costs do food truck owners often forget?
Vehicle depreciation, comprehensive insurance premiums, mobile payment processing fees, and small recurring expenses like cleaning supplies add up quickly. These overlooked items can total several hundred euros monthly.
How do I handle VAT if I operate in multiple locations?
VAT obligations remain consistent regardless of where you operate within the same country. Keep detailed daily records of all sales locations since some jurisdictions require location-specific reporting for mobile food vendors.
