Most restaurant owners think they're profitable when they're actually bleeding money. They calculate break-even using only food costs, completely ignoring labor expenses. This dangerous oversight means you could be operating at a loss while believing you're in the green.
What is the break-even point?
The break-even point represents the exact revenue level where you make zero profit and zero loss. Every cost gets covered, but there's nothing left over. It's your financial baseline - fall below this number and you're losing money.
💡 Example:
Restaurant serving 50 covers daily, operating 6 days weekly:
- Food cost: 32% of revenue
- Labor costs: 35% of revenue
- Other costs: €8,000 per month
Break-even revenue: €24,242 per month
Which costs do you include?
Accurate break-even calculations require every single cost. Sort them into two categories:
Variable costs (fluctuate with sales volume):
- Food cost (all ingredients and supplies)
- Labor costs for all staff members
- Optional: delivery platform commission fees
Fixed costs (remain constant):
- Monthly rent payments
- Insurance premiums
- Utility bills (mostly fixed portion)
- Equipment depreciation
- Administrative expenses
- Marketing and advertising
The break-even formula
The calculation combining food cost and labor costs looks like this:
Break-even revenue = Fixed costs ÷ (1 - Variable costs %)
Variable costs % equals food cost % plus labor costs % (plus any additional variable percentages)
💡 Example calculation:
Bistro operating with these numbers:
- Food cost: 30% of revenue
- Labor costs: 32% of revenue
- Fixed costs: €6,500 per month
Calculation: €6,500 ÷ (1 - 0.62) = €6,500 ÷ 0.38 = €17,105 per month
Determining food cost percentage
Calculate your food cost percentage by dividing average ingredient expenses by average selling prices (excluding VAT). From analyzing actual purchasing data across different restaurant types, the most accurate approach involves checking your top revenue-generating dishes and averaging those percentages.
⚠️ Note:
Always work with VAT-exclusive prices. Menu prices include 9% VAT for food items. Divide menu prices by 1.09 to get the VAT-exclusive amount.
Calculating labor costs percentage
Labor expenses typically rank as your second-largest cost after ingredients. Include every personnel expense:
- Gross salary payments
- Employer contributions (roughly 25% above gross wages)
- Holiday allowances
- Optional: 13th month payments, performance bonuses
Divide total monthly labor costs by monthly revenue to get your labor percentage.
💡 Example labor costs:
Restaurant generating €25,000 monthly revenue:
- Head chef: €3,200 gross + €800 employer contributions
- Line cook: €2,800 gross + €700 employer contributions
- Wait staff: €2,400 gross + €600 employer contributions
Total: €10,500 ÷ €25,000 = 42% labor costs
Converting break-even to covers
Transform your break-even revenue into daily guest requirements. Simply divide break-even revenue by your average spending per customer.
Average bill equals total revenue divided by total covers during the same timeframe.
When you don't reach your break-even
Operating below break-even leaves you with three strategic options:
- Boost revenue: attract more customers or increase average spending
- Reduce fixed costs: negotiate lower rent, cancel unnecessary subscriptions
- Cut variable costs: optimize food costs or improve staff efficiency
⚠️ Note:
Excessive labor cuts damage service quality and customer experience. Focus on workflow improvements before considering staff reductions.
Break-even monitoring
Review your break-even performance monthly. Three consecutive months below break-even demands immediate corrective action. Delaying only worsens your financial position.
Real-time tracking systems help you monitor food cost percentages and make quick adjustments when expenses spike unexpectedly.
How do you calculate your break-even point? (step by step)
Gather all your costs
Make a list of all fixed costs per month (rent, insurance, energy) and calculate your food cost and labor costs as a percentage of your revenue. Add up all personnel costs including employer contributions.
Calculate your variable costs percentage
Add food cost percentage and labor costs percentage together. This is the percentage of every euro of revenue that goes to variable costs. The remaining percentage is available for fixed costs and profit.
Apply the break-even formula
Divide your total fixed costs per month by (1 minus your variable costs percentage). The result is the minimum revenue you need to break even without profit or loss.

Frequently asked questions
Should I include VAT in my break-even calculation?
Never include VAT in break-even calculations. VAT collected goes directly to tax authorities - it's not your revenue. Only count the money you actually keep after VAT obligations.
What if my food cost and labor costs together exceed 70%?
You're in serious trouble. With 70% variable costs, only 30% remains for fixed expenses and profit. Immediately audit your food costs and staff scheduling efficiency.
How often should I recalculate my break-even point?
Recalculate quarterly at minimum, or immediately after significant cost changes. Supplier price increases or wage adjustments directly impact your break-even threshold.
Can I factor seasonal fluctuations into break-even calculations?
Absolutely - calculate separate break-even points for peak and slow seasons. Quiet periods often mean reduced labor costs but identical fixed expenses, shifting your break-even requirements.
What if I'm barely above break-even with no safety margin?
You're operating dangerously close to losses. Minor revenue drops or cost increases will push you into the red immediately. Target 10-15% above break-even as your minimum safety buffer.
How do I handle break-even calculations with multiple revenue streams?
Calculate weighted averages for different revenue sources like dine-in, takeout, and catering. Each stream has different cost structures and profit margins that affect your overall break-even point.
