Calculating expected revenue is crucial for your business plan. Many starting entrepreneurs estimate this too optimistically, while successful operators know that conservative projections prevent financing disasters. Here's how to build realistic revenue expectations using occupancy rates and average bill values.
The basics: occupancy × average bill
Your revenue consists of two components: how many guests you serve and what each guest spends. This formula appears straightforward, but it's packed with potential mistakes.
Basic revenue formula:
Revenue = Number of covers × Average bill value × Number of days open
? Example calculation:
Restaurant with 40 seats, open 6 days per week:
- Average occupancy: 60% (24 guests per service)
- 2 services per day (lunch + dinner): 48 covers/day
- Average bill value: €28.50
- Per week: 48 × 6 = 288 covers
Weekly revenue: 288 × €28.50 = €8,208
Annual revenue: €8,208 × 52 = €426,816
Realistic occupancy percentages per phase
Many entrepreneurs calculate with 80% occupancy from day one. That's completely unrealistic. New businesses build momentum gradually.
- Month 1-3: 20-30% average occupancy
- Month 4-6: 35-45% average occupancy
- Month 7-12: 45-60% average occupancy
- Year 2+: 55-75% average occupancy (depending on location)
⚠️ Note:
Never calculate with 100% occupancy. Even top restaurants average 70-80%. There are always quiet days, weather impacts and seasonal dips.
Determining average bill value
Your average bill value depends on your concept, location and target market. Research similar businesses in your neighborhood to get accurate benchmarks.
Common bill values per concept:
- Casual dining: €22-32 per person
- Fine dining: €45-75 per person
- Bistro/brasserie: €28-38 per person
- Lunch café: €12-18 per person
- Pizzeria: €18-25 per person
? Example bill value breakdown:
Bistro - average order per person:
- Appetizer: €8.50 (60% of guests)
- Main course: €19.50 (100% of guests)
- Dessert: €7.50 (40% of guests)
- Beverages: €12.00 average per person
Calculation: (€8.50 × 0.6) + €19.50 + (€7.50 × 0.4) + €12.00 = €37.60
Seasonal influences and weekly patterns
Your revenue fluctuates throughout the year. Factor this into your calculations to avoid cash flow disasters.
Typical seasonal patterns:
- January-February: -20% (post-holiday slump)
- March-May: +5% (spring recovery)
- June-August: -10% (vacation period)
- September-November: +10% (autumn peak)
- December: +15% (holiday season)
⚠️ Note:
Plan your cash flow for the slowest months. If you can survive January and February, you'll weather the rest of the year.
Estimating weekly patterns
Not every day brings equal traffic. Monday and Tuesday typically drag, while Friday and Saturday drive most revenue.
Average distribution per weekday:
- Monday: 60% of average day
- Tuesday: 70% of average day
- Wednesday: 85% of average day
- Thursday: 100% of average day
- Friday: 140% of average day
- Saturday: 160% of average day
- Sunday: 85% of average day (if open)
? Example weekly distribution:
Restaurant with average 50 covers per day:
- Monday: closed
- Tuesday: 35 covers (70%)
- Wednesday: 43 covers (85%)
- Thursday: 50 covers (100%)
- Friday: 70 covers (140%)
- Saturday: 80 covers (160%)
Total week: 278 covers (average 56 per opening day)
Market research and validation
Based on real restaurant P&L data, overly optimistic projections cause 60% of financing shortfalls. Validate your assumptions through thorough market research.
- Visit comparable businesses at different times
- Count covers and estimate bill values
- Talk to local entrepreneurs
- Check reviews: what do people order?
- Research local events and seasonal peaks
Conservative vs. optimistic scenarios
Always create three scenarios for your business plan: conservative, realistic and optimistic. Smart operators plan financing around the conservative numbers.
? Example three scenarios:
Restaurant 40 seats, open 6 days:
- Conservative: 45% occupancy, €26 bill value = €316,000/year
- Realistic: 55% occupancy, €29 bill value = €421,000/year
- Optimistic: 65% occupancy, €32 bill value = €545,000/year
Plan your financing on the conservative scenario!

How do you calculate expected revenue? (step by step)
Determine your capacity and opening hours
Count your seats, determine how many services per day you run and which days you're open. This is your theoretical maximum.
Estimate realistic occupancy percentages per period
Start conservatively: 25% in months 1-3, building up to 55-65% after a year. Never calculate with more than 75% average.
Research average bill values in your market
Visit comparable businesses, study menus and estimate what guests spend on average. Be realistic about your price level.
Calculate per month and build in seasonal variation
Use the formula: covers × bill value × days open. Adjust for seasons (January -20%, December +15%).
Create three scenarios and validate with market research
Calculate conservative, realistic and optimistic scenarios. Plan your financing on the conservative scenario.
✨ Pro tip
Track your actual covers versus projections weekly for the first 6 months. Adjust your cash flow forecasts immediately if you're running 15% below conservative estimates.
