A realistic business plan forms the foundation for every successful restaurant launch. Many entrepreneurs underestimate costs and overestimate revenue, causing them to go bankrupt within a year. Here's how to create an honest business plan that matches reality.
Start with realistic revenue forecasts
The biggest mistake in restaurant business plans? Overly optimistic revenue forecasts. Many entrepreneurs calculate with "full house every night", but reality tells a different story.
💡 Example realistic revenue forecast:
Restaurant with 40 seats, open 6 days:
- Average 60% occupancy (24 guests per service)
- Average check: €32 per person
- Per evening: 24 × €32 = €768
- Per week: €768 × 6 = €4,608
- Per year: €4,608 × 50 weeks = €230,400
Realistic annual revenue: €230,400
Always calculate with 50 weeks, not 52. You'll be closed for vacation, holidays and maintenance - that's just reality.
Calculate your fixed costs accurately
Fixed costs keep running, even if you're not generating revenue. These are crucial for your break-even calculation and shouldn't be underestimated.
💡 Example monthly fixed costs:
- Rent: €3,500
- Energy: €800
- Insurance: €350
- Phone/internet: €150
- Accountant: €200
- Software/licenses: €100
- Depreciation inventory: €800
Total per month: €5,900
Per year: €70,800
Don't forget depreciation on inventory - kitchen equipment and furniture lose value even though you don't pay for them monthly.
Plan your variable costs realistically
Variable costs increase with your revenue. Food cost and labor are your biggest ones, and from tracking this across dozens of restaurants, these percentages hold true across different concepts.
- Food cost: 28-35% of revenue for restaurants
- Labor: 25-35% of revenue (including employer contributions)
- Other variable costs: 5-8% (cleaning, repairs, marketing)
⚠️ Note:
Always calculate labor including employer contributions - pension premium, health insurance, etc. This adds approximately 25% on top of gross salary.
Calculate your break-even point
Your break-even is where revenue equals total costs. Below that point, you're losing money - simple as that.
Formula: Break-even revenue = Fixed costs / (1 - Variable costs %)
💡 Break-even calculation:
Using the figures above:
- Fixed costs: €70,800 per year
- Variable costs: 68% (32% food + 30% labor + 6% other)
- Break-even: €70,800 / (1 - 0.68) = €221,250
You need at least €221,250 in revenue to break even
In this example, with a €230,400 forecast, you're just above break-even. That's tight but realistic for year one.
Create a cashflow plan
Profit on paper doesn't equal money in the bank. Create a monthly cashflow plan for your first year - you'll need it.
- Account for late payments from business customers
- Plan investments in inventory and renovations
- Account for VAT payments per quarter
- Reserve for unexpected costs (10% of revenue)
Financing and startup capital
Calculate exactly how much money you need for startup and those crucial first months. Underestimate this, and you're setting yourself up for failure.
💡 Startup capital calculation:
- Renovation and inventory: €80,000
- Working capital first 3 months: €35,000
- Contingency (20%): €23,000
- Your living expenses 6 months: €18,000
Total startup capital needed: €156,000
Plan for at least 6 months of working capital. Those first months often generate less revenue than you've planned for - and that's normal.
How do you create a realistic business plan? (step by step)
Research the market and location
Analyze similar restaurants in your area. Check their prices, occupancy and concept. Ask the municipality about foot traffic and parking spaces.
Calculate realistic revenue forecasts
Start with 50-60% occupancy, not 100%. Calculate with 50 working weeks per year. Base your average check on similar businesses in the area.
Create a complete cost breakdown
List all fixed and variable costs. Don't forget: depreciation, employer contributions, insurance and a reserve for contingencies.
Calculate your break-even point
Use the formula: fixed costs divided by (1 minus variable costs percentage). This is your minimum revenue to break even.
Create a cashflow plan
Plan your income and expenses month by month. Account for late payments and seasonal fluctuations. Keep at least 3 months of working capital in reserve.
✨ Pro tip
Test your revenue assumptions by spending 3 full days observing similar restaurants in your area during different times and seasons. Count actual customers, estimate average spend, and adjust your projections down by 15-20% from what you observe.

Frequently asked questions
How much startup capital do I need for a restaurant?
For an average restaurant with 40 seats, you need €150,000-€200,000. This includes renovation, inventory, working capital and your living expenses for 6 months. Don't cut corners on this calculation.
What's a realistic occupancy rate for a new restaurant?
In your business plan, calculate with 50-60% occupancy. New restaurants need time to build awareness and a customer base. Planning for 100% occupancy every night is a recipe for disappointment and cash flow problems.
Should I factor in seasonal fluctuations for my revenue projections?
Absolutely - most restaurants see 20-30% revenue swings between peak and slow seasons. Plan your cash reserves accordingly, especially for your first year. Summer and holiday periods can make or break your annual numbers.
