Most food truck owners will confess after a few drinks that they've been guessing their break-even point for months. Fixed costs devour your cash flow regardless of your customer count. The scary part? You can feel busy all day and still lose money.
Why minimum revenue matters more than you think
Your food truck burns cash even when parked. Stand rental, fuel, insurance, perishable ingredients - they don't care about your sales numbers.
⚠️ Watch out:
Most food truck owners only count ingredient costs. Every sold burger feels like profit, but closing time reveals the harsh truth - you're still bleeding money.
Map out every fixed cost
Time for some uncomfortable math. List every expense that hits you regardless of customer volume:
- Stand rental: €50-150 per day (prime spots cost more but deliver volume)
- Fuel: €20-40 per day (driving plus generator runtime adds up quickly)
- Insurance: €8-15 per day (annual premiums divided by operating days)
- Truck depreciation: €30-80 per day (your mobile kitchen loses value constantly)
- Permits: €5-20 per day (bureaucracy costs money)
- Mobile costs: €3-8 per day (card readers, phone bills, connectivity)
💡 Example:
Typical food truck daily expenses:
- Stand rental: €80
- Fuel: €30
- Insurance: €12
- Depreciation: €50
- Permits: €10
- Other costs: €18
Total fixed costs per day: €200
Calculate your survival number
Fixed costs are just the start. Variable costs (ingredients, packaging) grow with every sale. Based on real restaurant P&L data, food trucks typically run 35-45% variable costs because packaging expenses destroy margins.
The formula:
Minimum revenue = Fixed costs / (1 - Variable costs %)
💡 Real numbers:
Fixed costs: €200 per day
Variable costs: 40% (food + packaging)
Minimum revenue = €200 / (1 - 0.40) = €200 / 0.60 = €333 per day
Hit €334? Congratulations, you just earned your first euro of actual profit.
Convert to customer count
Abstract numbers don't help when you're sweating behind the grill. Translate your minimum into customers served, broken down hourly so you can track progress.
- Calculate your average transaction value
- Divide minimum revenue by that average
- Spread across your operating hours
💡 Breaking it down:
Minimum revenue: €333
Average transaction: €12
Operating hours: 8
Minimum customers needed: €333 / €12 = 28 customers
Per hour target: 28 / 8 = 3.5 customers hourly
Four hours in with only 10 customers? Time to panic or pivot.
Account for weather reality
Food trucks live at the mercy of conditions you can't control. Build minimum targets for different scenarios:
- Peak conditions: Bank extra profit for inevitable slow days
- Standard days: Your baseline minimum target
- Terrible conditions: Sometimes closing early saves more money than staying open
⚠️ Reality check:
Consistently missing your minimum? Your fixed costs are too high for that location, or your pricing strategy needs serious work.
Monitor and adapt
Track daily performance against your minimum. Patterns emerge faster than you'd expect:
- Which days or locations consistently drain money?
- What conditions generate profit above your minimum?
- How much does weather actually hurt revenue?
- Which menu items deliver the highest margins?
Food cost calculators can track per-dish profitability and automatically calculate break-even points for various scenarios.
How do you calculate your minimum revenue? (step by step)
List all fixed costs per day
Write down stand rental, fuel, insurance, truck depreciation, permits and other costs. Convert annual costs to daily amounts by dividing by 365. Add everything up for your total fixed costs per day.
Determine your variable costs percentage
Calculate your average food cost including packaging across all your menu items. For food trucks this is usually between 35-45%. Include ingredients, packaging, napkins and sauces all together.
Calculate your minimum revenue
Use the formula: Fixed costs / (1 - Variable costs %). For example €200 fixed costs and 40% variable costs = €200 / 0.60 = €333 minimum revenue per day.
Translate to number of customers
Divide your minimum revenue by your average transaction value. This way you know how many customers you need at minimum. Spread this across your opening hours to know where you need to stand per hour.
✨ Pro tip
Track your hourly customer count for 14 days and identify your 3 slowest hours. Most food trucks discover they lose €40-80 staying open those final hours when foot traffic dies but generator costs keep running.

Frequently asked questions
What if I regularly don't reach my minimum revenue?
Your fixed costs are too high for that location or your prices need adjustment. Find a cheaper spot, raise prices strategically, or add high-margin items that customers actually want.
Should I include my own salary in fixed costs?
Absolutely - budget at least €100-150 daily for your labor. Working for free might feel noble, but it prevents building reserves for repairs and replacements. You're running a business, not a charity.
How often should I recalculate my minimum revenue?
Review monthly since costs fluctuate regularly. Fuel prices spike, rent increases, ingredient costs shift. Adjust your minimum immediately when costs increase permanently, not after you've been losing money for weeks.
Should I include VAT in my minimum revenue calculation?
Never calculate with VAT-inclusive amounts. That VAT goes straight to tax authorities - it's not your revenue. €121 including VAT equals €100 actual revenue for your business.
