Nearly 30% of restaurants close within their first year, primarily due to insufficient working capital planning. Working capital bridges the financial gap before profits arrive. Calculate exactly how much cash you need to survive those critical first three months.
What exactly is working capital?
Working capital represents the difference between your current assets (cash, inventory, outstanding invoices) and short-term liabilities (suppliers, loans, taxes). For new restaurants, it's simpler: how much money keeps your doors open before turning a profit?
⚠️ Watch out:
Many entrepreneurs only budget for fixtures and equipment, forgetting operational cash flow. That's why 30% of restaurants close within the first year.
The components of working capital
Your working capital needs consist of five parts:
- Fixed costs: Rent, insurance, utilities, phone
- Personnel costs: Wages, payroll taxes, staffing
- Food and beverage purchases: Initial inventory + ongoing purchases
- Other operational costs: Marketing, cleaning, repairs
- Buffer for emergencies: At least 20% extra
Calculate your monthly fixed costs
Start with expenses you'll pay regardless of customer volume:
? Example fixed costs:
- Rent: €4.500
- Utilities: €800
- Insurance: €350
- Phone/internet: €150
- Waste/cleaning: €200
Total fixed costs: €6.000/month
Estimate your personnel costs
Calculate all staff expenses, including your own salary. For a 40-seat restaurant:
? Example personnel costs:
- Head chef (yourself): €3.500
- Sous chef: €2.800
- Service staff (2 FTE): €4.400
- Payroll taxes (30%): €3.210
Total personnel costs: €13.910/month
Calculate your food & beverage costs
For opening months, you'll face two F&B expense types:
- Starting inventory: Initial stock to fill coolers and shelves
- Ongoing purchases: Monthly buying based on projected revenue
? Example F&B costs:
Expected revenue month 1: €25.000
- Food cost 30%: €7.500/month
- Starting inventory: €3.000 (one-time)
- Beverage inventory: €2.000 (one-time)
F&B first month: €12.500
Other operational costs
Don't overlook these essential expenses:
- Marketing and advertising: €1.000/month
- Administration and software: €300/month
- Maintenance and repairs: €500/month
- Contingency: €500/month
The buffer calculation
Always include a 20-30% buffer in your calculations. Something unexpected always happens during opening months:
⚠️ Watch out:
First-month revenue typically runs 40-60% below projections. So plan for lower income but maintain full expense levels in your working capital calculations.
Three-month calculation
For realistic working capital needs, model gradual revenue increases while maintaining consistent costs:
? Example 3-month overview:
Month 1:
- Fixed costs: €6.000
- Personnel: €13.910
- F&B: €12.500 (incl. starting inventory)
- Other: €2.300
- Subtotal: €34.710
Month 2-3: €27.210 per month
Total 3 months: €89.130 + buffer 25% = €111.400
Managing working capital in practice
Based on real restaurant P&L data, food costs often exceed projections by 15-25% during opening months. A food cost calculator helps track actual spending against budget. Check your numbers weekly during those crucial first months.

Calculate your total personnel costs including payroll taxes
Add up all wages (including yourself) and add 30% for payroll taxes. These are your monthly personnel costs that you have from day one.
Estimate your food & beverage costs for 3 months
Calculate 30% of your expected revenue for food cost, plus one-time starting inventory. Calculate the first 3 months with lower revenue than you hope for.
Add everything up and add a 25% buffer
Sum all costs for 3 months and add at least 25% buffer. This is your working capital need that you need in addition to your investments.
✨ Pro tip
Calculate working capital assuming 45% lower revenue than projected for your first 90 days. Most restaurant failures stem from overestimating opening-month income while underestimating cash burn rates.
