Picture this: you've found what seems like the perfect restaurant space, but three months after opening, you're struggling to make rent. Many entrepreneurs choose locations based on gut feeling, completely forgetting to check whether they can actually earn enough to cover the monthly payments. Here's how to calculate a realistic rent ceiling before you sign anything.
Why a rent ceiling matters so much
You can have the most beautiful restaurant, but if rent's too high, you'll go bankrupt. Many hospitality entrepreneurs seriously underestimate how much revenue they need to cover all costs.
Sure, there's a rule of thumb: rent should be at most 20-25% of your expected revenue. But that's way too simple. You've got to account for every single cost.
Calculate your total monthly costs
Before determining a rent ceiling, you need to know exactly what it costs your restaurant to operate each month:
? Example cost breakdown bistro (50 seats):
- Staff: €8,000 per month
- Food purchases: €6,000 per month
- Energy: €800 per month
- Insurance: €300 per month
- Other costs: €900 per month
Total without rent: €16,000 per month
Estimate your realistic revenue
Now you need to honestly estimate how much revenue you can generate. After managing kitchen operations for nearly a decade, I've seen too many owners get this wrong. Look at:
- Number of seats: How many covers per day are realistic?
- Average bill: What does a guest spend on average?
- Number of opening days: 6 or 7 days per week?
- Seasons: Are there quiet months?
? Example revenue calculation:
50 seats, average 60 covers per day, €22 average bill:
- Per day: 60 × €22 = €1,320
- Per week (6 days): €1,320 × 6 = €7,920
- Per month: €7,920 × 4.33 = €34,295
Monthly revenue: €34,295
⚠️ Note:
Be conservative with your revenue estimate. Better to be cautious than disappointed. It often takes 6-12 months before you're operating at full capacity.
Calculate your maximum rent
Now you can figure out how much rent you can afford while still making a profit:
Formula:
Maximum rent = Expected revenue - All other costs - Desired profit
? Example calculation:
- Expected revenue: €34,295
- Costs without rent: €16,000
- Desired profit: €3,000
Maximum rent: €34,295 - €16,000 - €3,000 = €15,295
That's 44% of revenue - way too high! A more realistic rent ceiling is €6,000-€7,000.
Apply the 20% rule as maximum
A safe rule of thumb: keep your rent below 20% of your expected revenue. And if you're unsure, go lower, not higher.
- 15-18%: Safe, plenty of room for setbacks
- 18-22%: Acceptable, but little margin for error
- 22%+: Risky, only if you're absolutely certain you'll hit your revenue targets
Calculate different scenarios
Create three scenarios: optimistic, realistic, and pessimistic. Your rent ceiling should be based on the pessimistic scenario.
? Example three scenarios:
- Optimistic: €40,000 revenue → max €8,000 rent
- Realistic: €34,000 revenue → max €6,800 rent
- Pessimistic: €28,000 revenue → max €5,600 rent
Safe rent ceiling: €5,600
Don't forget additional costs
Rent isn't just the monthly rental price. Add these costs as well:
- Service charges: Cleaning common areas, maintenance
- Utilities: Sometimes separate, sometimes included in rent
- Municipal charges: Waste disposal fees, sewage charges
- Insurance: Building insurance, business liability
⚠️ Note:
Always ask for the total monthly charges, not just the base rent. Additional costs can be 20-30% on top of the rent.

Subtract your total costs and desired profit from your expected revenue. What's left is your absolute rent ceiling.
Check the 20% rule
Is your rent ceiling more than 20% of your revenue? Then go for lower rent or find a cheaper location. Safety comes first.
