What's the minimum revenue your restaurant needs to survive each month? Most restaurant owners guess at their break-even point, leading to months of hidden losses. Here's how to calculate your exact survival threshold.
What is break-even revenue?
Break-even revenue marks the point where your income equals your costs. You're not making profit, but you're not losing money either. Every dollar above this threshold becomes pure profit.
💡 Example:
Restaurant with €8,000 fixed costs per month and 35% variable costs:
- Rent: €3,500
- Staff: €3,200
- Insurance: €800
- Energy: €500
Break-even: €12,308 revenue per month
Fixed vs. variable costs
You need to categorize your expenses into two distinct groups for accurate calculations:
Fixed costs (remain constant regardless of sales volume):
- Rent and lease payments
- Salaried staff wages
- Insurance premiums
- Software and phone subscriptions
- Equipment depreciation
Variable costs (fluctuate with revenue):
- Food ingredients and beverages
- Hourly staff wages
- Utility costs (partially variable)
- Delivery packaging materials
- Third-party platform commission fees
⚠️ Note:
Labor costs often split between categories. Your head chef's salary is fixed, but extra weekend help is variable.
The break-even formula
The calculation for break-even revenue follows this formula:
Break-even revenue = Fixed costs ÷ (1 - Variable cost percentage)
Variable cost percentage equals your variable expenses divided by total revenue.
💡 Example calculation:
Bistro with these monthly figures:
- Fixed costs: €6,500
- Variable costs: 40% of revenue
Break-even: €6,500 ÷ (1 - 0.40) = €6,500 ÷ 0.60 = €10,833
At €10,833 in sales, you'll generate exactly zero profit.
Break-even by restaurant type
Different restaurant concepts carry unique cost structures:
Fine dining establishments:
- High fixed expenses (experienced staff, prime locations)
- Lower variable costs (30-35%)
- Break-even typically €15,000-25,000 monthly
Fast casual operations:
- Moderate fixed expenses
- Higher variable costs (35-45%)
- Break-even typically €8,000-15,000 monthly
Delivery and takeaway:
- Minimal fixed costs (no table service required)
- Elevated variable costs (platform commission fees)
- Break-even typically €6,000-12,000 monthly
💡 Practical example pizzeria:
Pizzeria offering delivery with 25 seats:
- Rent: €2,800
- Fixed staff: €2,500
- Other fixed: €900
- Variable costs: 45% (ingredients plus platform fees)
Break-even: €6,200 ÷ 0.55 = €11,273 monthly
From break-even to profit
Once you surpass your break-even threshold, each additional euro in sales becomes profitable. With 40% variable costs, an extra €1,000 in revenue translates to €600 in profit.
Most successful restaurants target 15-25% profit margins. If your break-even sits at €12,000 and you want 20% profit, you'll need €15,000 in monthly revenue.
⚠️ Note:
Break-even represents your survival minimum, not your target. Always build in profit margins for unexpected expenses and growth investments.
Review and adjustment
Your break-even point shifts constantly due to:
- Lease renewal increases
- Minimum wage adjustments
- Supplier price inflation
- New equipment or software purchases
Based on real restaurant P&L data, successful operators recalculate every quarter to catch cost creep early. Food cost calculators can instantly show how expense changes impact your break-even threshold.
How do you calculate your break-even revenue? (step by step)
Make a list of all fixed costs per month
Add up: rent, fixed staff, insurance, subscriptions, depreciation. These are costs you always have, even at €0 revenue.
Calculate your variable costs percentage
Divide your monthly variable costs (food, flexible staff, platform fees) by your average revenue. This gives you your variable costs %.
Apply the break-even formula
Break-even = Fixed costs / (1 - Variable costs %). This is the minimum revenue you need to cover all costs.
✨ Pro tip
Compare your calculated break-even against actual revenue from the past 90 days. If you're consistently operating 15% below break-even, you have 30 days to cut costs or raise prices before cash flow becomes critical.

Frequently asked questions
What if my variable costs percentage changes every month?
Calculate the average from your last 3-6 months of operations. Seasonal fluctuations and supplier price variations make this completely normal. Use the average for more stable planning.
Should I include VAT in my break-even calculation?
Always work with pre-VAT amounts in your calculations. The VAT you collect from customers gets remitted to tax authorities, so it's not actually your revenue.
What if I'm above break-even but still have no cash flow?
You've likely missed expenses in your calculation or underestimated variable costs. Double-check your actual food costs and labor expenses against your projections. Hidden costs often lurk in credit card fees and maintenance.
