Are you making money with that terrace, or just creating more work for yourself? Those extra seats look promising on paper, but the real test is in the numbers. Most restaurant owners forget to count the hidden costs that eat into those shiny revenue projections.
Calculate your extra revenue potential
Start by estimating realistic guest numbers your terrace can attract. Weather, location, and seasonality all play major roles here.
💡 Example revenue calculation:
Restaurant with 30 indoor seats gets 20 terrace seats:
- Terrace occupancy: 60% (lower than indoors due to weather)
- Average bill on terrace: €22 (often lunch/drinks)
- Operating days per season: 180 days
- Average 1.5 seatings per day
Extra revenue: 20 × 0.6 × €22 × 1.5 × 180 = €71,280 per season
Add up all extra costs
Your terrace isn't free money. Hidden costs can quickly eat into those promising revenue numbers.
Staff and service
More tables mean more work, period. You'll need at least 0.5 FTE additional staff during terrace season - from tracking this across dozens of restaurants, most underestimate this by 20-30%.
- Service: €2,500 per month × 6 months = €15,000
- Kitchen: 30% more volume requires extra kitchen hours
- Cleaning: Daily terrace cleaning takes time
Furniture and equipment
💡 Example startup costs:
- 20 tables + 80 chairs: €8,000
- Parasols and heating: €4,000
- Lighting: €2,000
- Windscreens: €3,000
Total investment: €17,000
Operational costs
Don't overlook the ongoing expenses that come with outdoor dining:
- Terrace permit: €500-2,000 per year (varies by municipality)
- Insurance: €300-800 extra per year
- Energy: Lighting and heating €100-300 per month
- Maintenance: Furniture replacement, repairs €1,000 per year
Calculate your break-even point
Now you can determine exactly when your terrace investment pays off. The formula is straightforward:
Break-even = Total investment / (Monthly extra profit)
💡 Example break-even calculation:
With €71,280 extra revenue per season:
- Food cost (30%): €21,384
- Extra staff: €15,000
- Operational costs: €3,600
Net profit per season: €31,296
Break-even: €17,000 / €31,296 = 0.54 season (6.5 months)
⚠️ Note:
Calculate conservatively with your occupancy rate. Weather and season dramatically impact terrace revenue. Start with 50-60% occupancy instead of 80%.
Cashflow impact in the first year
Terraces require big upfront investments while income arrives seasonally. Plan your cashflow accordingly.
- March: Investment €17,000 + permits
- April-September: Monthly profit €5,200
- October-February: No terrace revenue, but depreciation continues
You'll spend 6-8 months in your first year recovering that initial investment.
Boost your chances of success
A few practical strategies to make your terrace more financially successful:
- Start small: Begin with 10-15 seats, expand if it works
- Winter storage: Rent storage space to offset empty months
- All-weather solution: Canopy and heating extend the season
- Special terrace menu: Higher margins on drinks and snacks
💡 Pro tip:
Track your terrace revenue separately in your POS system. This gives you exact data on you're hitting targets and where adjustments are needed.
How do you calculate the financial impact? (step by step)
Estimate your extra revenue
Calculate number of terrace seats × realistic occupancy × average bill × number of operating days. Account for season and weather - calculate conservatively with 50-60% occupancy.
Add up all costs
Add startup investment (furniture, permits) to operational costs (extra staff, energy, maintenance). Don't forget hidden costs like extra cleaning and insurance.
Calculate your break-even
Subtract food cost and all extra costs from your extra revenue. Divide your total investment by your monthly net profit to see how many months until you break even.
✨ Pro tip
Track your actual terrace profits daily for the first 90 days - most operators discover their break-even calculation was off by 2-3 months. This early data helps you adjust pricing and staffing before the season ends.

Frequently asked questions
How much extra revenue can I expect from a terrace?
This depends on your location and terrace size, but plan for €2,000-4,000 extra revenue per terrace seat per season. A 20-seat terrace can generate €40,000-80,000 in extra revenue.
What are the biggest cost items for a terrace?
The biggest costs are usually extra staff (€15,000+ per season) and the startup investment in furniture (€10,000-20,000). Operational costs like permits and energy are relatively small but add up over time.
How long does it take for my terrace to pay for itself?
For an average terrace, payback time is 6-18 months, depending on your investment and profitability. Plan for at least one full season before you break even.
What if the weather is bad during terrace season?
Bad weather can reduce your revenue by 30-50%. That's why calculating conservatively matters so much. Consider investing in a canopy or heating to extend your season and reduce weather dependency.
