How do I calculate break-even with different scenarios of occupancy and average bill?

📝 KitchenNmbrs · updated 14 Mar 2026

How many guests do you actually need each month to keep your doors open? Most restaurant owners guess at their break-even point, then wonder why they're bleeding money three months later. Here's how to calculate your exact break-even for any combination of occupancy and average bill.

What is break-even and why is it crucial?

Break-even is the point where your revenue equals your total costs. You're making no profit, but also no loss. It's the minimum number of guests you need to pay your bills.

💡 Example:

Restaurant with 50 seats, open 6 days a week:

  • Fixed costs per month: €12,000 (rent, staff, energy)
  • Variable costs: 35% of revenue (food, drinks)
  • Average bill: €32.50

Break-even: 569 guests per month

The break-even formula for restaurants

The basic formula for break-even in covers (number of guests) is:

Break-even covers = Fixed costs / (Average bill - Variable costs per guest)

Where:

  • Fixed costs: rent, permanent staff, insurance, depreciation
  • Average bill: revenue divided by number of guests
  • Variable costs per guest: food cost + drink costs + any extra staff

⚠️ Note:

Always calculate with prices excluding VAT. The revenue on your receipt includes 9% VAT for food.

Scenario 1: High occupancy, low average bill

This scenario fits fast, casual concepts like lunch cafés or pizzerias. You'll need volume to make it work.

💡 Example lunch café:

40 seats, 2 shifts per day, 6 days a week:

  • Fixed costs: €8,500 per month
  • Average bill: €18.50 (€16.97 excl. VAT)
  • Variable costs: €5.60 per guest (33% of bill)

Break-even: €8,500 / (€16.97 - €5.60) = 749 guests per month

That's 31 guests per day, or 78% occupancy per shift.

Scenario 2: Average occupancy, average bill

The most common scenario for bistros and casual dining restaurants. Here's where many owners make a mistake that costs the average restaurant EUR 200-400 per month - they assume 50% occupancy is enough without doing the math first.

💡 Example bistro:

60 seats, 1 shift per day, 6 days a week:

  • Fixed costs: €15,000 per month
  • Average bill: €42.00 (€38.53 excl. VAT)
  • Variable costs: €13.50 per guest (35% of bill)

Break-even: €15,000 / (€38.53 - €13.50) = 599 guests per month

That's 25 guests per day, or 42% occupancy.

Scenario 3: Low occupancy, high average bill

Typical for fine dining restaurants with longer seating times and higher prices. But fewer guests means each one counts more.

💡 Example fine dining:

45 seats, 1 shift per day, 5 days a week:

  • Fixed costs: €18,000 per month
  • Average bill: €85.00 (€77.98 excl. VAT)
  • Variable costs: €26.00 per guest (33% of bill)

Break-even: €18,000 / (€77.98 - €26.00) = 347 guests per month

That's 17 guests per day, or 38% occupancy.

How seasons affect your break-even

Your break-even changes each month due to seasonal fluctuations in occupancy and costs.

  • Summer months: higher occupancy, but also higher staff costs
  • Winter months: lower occupancy, but stable fixed costs
  • Holidays: peak days can make up for a bad month

⚠️ Note:

Calculate your break-even per month, not per year. Otherwise you'll discover too late that you're entering a rough patch.

Creating a break-even dashboard

Track these figures weekly to stay on top of your performance:

  • Number of guests this week vs. break-even number
  • Average bill this week vs. target bill
  • Occupancy rate per day (covers / number of seats)
  • Revenue so far this month vs. break-even revenue

With a system like tools available you can track these figures automatically and get alerts if you're falling behind on your break-even.

How do you calculate break-even scenarios? (step by step)

1

Gather your fixed costs per month

Add up: rent, permanent staff, insurance, energy, depreciation, accountant. These are costs you always have, regardless of how many guests you serve.

2

Calculate your variable costs per guest

This is your food cost + drink cost per average bill. Usually 30-40% of your bill excl. VAT. Also include extra staff if you deploy that during busy times.

3

Determine your average bill per scenario

Lunch vs. dinner, weekday vs. weekend. Always calculate excl. 9% VAT. Divide your total revenue by number of guests for your current average.

4

Apply the formula per scenario

Break-even guests = Fixed costs / (Average bill excl. VAT - Variable costs per guest). Check if this is achievable with your seats and opening hours.

5

Convert to occupancy rate

Divide your break-even number of guests by your maximum capacity. If you need 80%+ occupancy to break even, your concept is risky.

✨ Pro tip

Run break-even scenarios every 6 weeks using your actual average bill from the past month. If your current pace puts you 15% below break-even, you have exactly 10 days to adjust pricing or boost marketing before you're in trouble.

Frequently asked questions

What if my break-even is higher than my maximum capacity?

Then you need to lower your costs or increase your average bill. Check if your rent is too high, or if your menu is priced too low. Sometimes it means your concept isn't viable at this location.

Should I calculate different break-evens for lunch and dinner?

Yes, if you charge different prices. Lunch usually has a lower average bill, so you need more guests to break even. Calculate both scenarios separately.

How often should I recalculate my break-even?

At least every 3 months, or if your prices or costs change. For seasonal businesses it's better to look at your break-even monthly for the coming period.

What is a healthy margin above break-even?

Aim for at least 20-30% more guests than your break-even. This gives you a buffer for disappointing months and room for profit and investments.

Does VAT count in my break-even calculation?

No, always calculate excl. VAT. The VAT you receive must be passed on to the tax authorities, so it's not real revenue for you.

How do I handle fluctuating food costs in my break-even?

Update your variable cost percentage quarterly based on actual food costs. If ingredients spike 15%, your break-even point shifts immediately. Don't wait until year-end to adjust.

Can I use break-even analysis for menu engineering decisions?

Absolutely. Calculate break-even for different menu mixes - if you push higher-margin dishes, you need fewer total guests. A 5% shift toward premium items can drop your break-even by 50+ covers monthly.
