Ever wondered exactly how many customers you need just to keep your doors open? Most restaurant owners operate on instinct, but that's dangerous territory. The real numbers tell you precisely how many daily covers are required to handle every expense that hits your books.
What is break-even in covers?
Break-even means your revenue equals total costs. You're not profiting, but you're not hemorrhaging money either. Every guest above that critical number drops cash directly into your pocket.
Restaurants measure break-even in daily covers because it's actionable. You can watch customers walk through the door, but revenue remains abstract numbers on a screen until you tally the day's sales.
Gather your fixed costs per month
Fixed costs hit your account regardless of serving 10 guests or 100:
- Rent: dining room, kitchen, storage space
- Staff: salaried employees (not hourly wages)
- Utilities: baseline gas, water, electricity
- Insurance: liability, property, workers' comp
- Equipment: monthly depreciation on ovens, POS systems
- Services: accounting, software subscriptions, phone bills
💡 Example fixed costs:
- Rent: €4,500
- Fixed salaries: €8,000
- Utilities: €800
- Insurance: €400
- Other: €600
Total: €14,300 per month
Calculate your variable costs percentage
Variable costs climb with guest volume. More customers means higher expenses:
- Food cost: ingredients for each dish served
- Hourly labor: extra kitchen and service staff during rush periods
- Additional utilities: more cooking drives up gas and electric bills
Express total variable costs as a percentage of revenue. Most restaurants land between 45-60%.
💡 Example variable costs:
For every €100 in sales:
- Food cost: €32 (32%)
- Variable labor: €15 (15%)
- Extra utilities: €3 (3%)
Total variable: €50 = 50% of revenue
Calculate your average bill amount
Pull data from your POS system covering the past 3 months:
- Total revenue ÷ total covers served
- Use tax-inclusive amounts (what customers actually pay)
- Exclude special events, catering, or unusual one-offs
⚠️ Warning:
Don't rely on just one strong month. After managing kitchen operations for nearly a decade, I've watched too many operators crash using peak-season numbers as their baseline.
The break-even formula
Here's how to calculate your daily guest requirement:
Break-even covers per day = Daily fixed costs ÷ (Average bill - Variable cost per guest)
Breaking it down:
- Daily fixed costs = Monthly fixed costs ÷ 30
- Variable cost per guest = Average bill × Variable percentage
💡 Complete calculation:
Using our example:
- Fixed costs: €14,300/month = €477/day
- Average bill: €35 including tax
- Variable costs: 50% = €17.50 per guest
Break-even = €477 ÷ (€35 - €17.50) = €477 ÷ €17.50 = 27.3 guests per day
You need at least 28 guests per day to break even.
Account for your operating schedule
Your actual operating days matter more than calendar days:
- Open 6 days weekly? You need higher daily volume
- Open 7 days weekly? Break-even spreads across more service days
- Seasonal operation? Calculate based on months you're actually open
If you operate 6 days per week, divide monthly fixed costs by 26 days, not 30.
From break-even to actual profit
Breaking even just keeps you afloat. Healthy restaurants target 20-30% above break-even:
💡 Profit target calculation:
Break-even: 28 guests/day
- 20% profit margin: 28 × 1.2 = 34 guests/day
- 30% profit margin: 28 × 1.3 = 36 guests/day
Each guest beyond 28 contributes €17.50 in pure profit.
How do you calculate your break-even in guests? (step by step)
Gather all fixed costs per month
Add up: rent, fixed salaries, energy, insurance, depreciation and other fixed costs. These are costs you always have, regardless of how many guests you serve.
Calculate your variable costs percentage
Determine what percentage of your revenue goes to variable costs (food cost, variable staff, extra energy). For restaurants this is usually 45-60% of revenue.
Check your average bill amount
Divide your total revenue from the last 3 months by the number of covers. This gives you the average amount each guest spends.
Apply the break-even formula
Break-even guests per day = Fixed costs per day divided by (Average bill minus variable costs per guest). This gives you the minimum number of guests you need daily.
✨ Pro tip
Calculate your break-even for the next 12 weeks, then compare actual covers against your target daily. Most operators discover they're missing their number by 18-22%, which explains persistent cash flow problems.

Frequently asked questions
Should I include VAT in the break-even calculation?
Use tax-inclusive amounts for average bill calculations since that's what customers pay. But remember, VAT gets remitted to the government, so it doesn't count as actual income.
What if my daily volume swings wildly?
Use at least 3 months of data to smooth out fluctuations. Consider calculating separate break-evens for weekdays versus weekends to see which days actually lose money.
How often should I recalculate my break-even?
Every 3-6 months minimum, or immediately after major cost changes like rent increases or menu overhauls. Your variable cost percentage shifts with ingredient prices and operational changes.
I'm hitting my break-even number but still running out of cash. What gives?
You're missing costs somewhere or underestimating variables. Double-check that you've included all taxes, loan payments, and owner draws in your calculations.
