The cashflow of an acquired restaurant must be able to support your loan, otherwise you're buying a problem. Most entrepreneurs focus solely on revenue numbers but overlook the monthly loan payments that'll hit your account. Here's how to calculate whether the cashflow can handle your financing.
What is cashflow and why is it crucial?
Cashflow represents actual money flowing in versus money flowing out. It's not theoretical profit on paper, but real dollars in your business account. For restaurant acquisitions, this matters because your lender expects payment every single month.
⚠️ Note:
Paper profits don't equal cashflow. Depreciation can show profitability while zero cash enters your account.
The cashflow calculation in 3 steps
Three key figures determine if your restaurant's cashflow supports the loan:
- Operating cashflow: Actual money the restaurant generates
- Loan burden: Monthly payment plus interest
- Safety margin: Buffer for slower months
💡 Example calculation:
Restaurant generating €40,000 monthly revenue:
- Revenue: €40,000
- Food cost (30%): €12,000
- Personnel costs: €14,000
- Fixed costs: €6,000
- Other costs: €2,000
Operating cashflow: €6,000 per month
Calculate operating cashflow
Begin with monthly revenue and subtract every real expense. Skip depreciation and accounting adjustments - only count what actually leaves your account:
- Food cost: Typically runs 28-35% of revenue
- Personnel costs: Wages plus social contributions (35-45%)
- Rent and fixed costs: Rent, utilities, insurance premiums
- Other operating costs: Marketing spend, maintenance, administrative expenses
The remainder becomes your operating cashflow. This money covers loan payments, taxes, and your own salary. From analyzing actual purchasing data across different restaurant types, food costs often spike during holiday periods, so factor seasonal variations into your calculations.
Loan burden and safety margin
Your operating cashflow needs to hit at least 150% of monthly loan payments. This cushion covers tax obligations and provides breathing room during slow periods.
💡 Practical example:
€300,000 loan over 10 years at 5% interest:
- Monthly loan payment: €3,182
- Minimum cashflow required: €4,773 (150%)
- Comfortable cashflow: €6,000+ monthly
€6,000 cashflow easily supports this loan structure.
Account for seasonal fluctuations
Restaurant revenue swings seasonally. So calculate cashflow using your worst-performing months, not yearly averages. If January's numbers can cover loan payments, you'll survive the entire year.
- Obtain monthly revenue data from the previous 24 months
- Run cashflow calculations for the 3 weakest months
- Verify these still reach 150% of loan obligations
⚠️ Note:
Sellers typically showcase peak months only. Demand complete yearly statements and VAT returns for verification.
What if the cashflow is too tight?
Insufficient cashflow leaves you with three solutions:
- Negotiate lower purchase price: Smaller loan equals reduced monthly burden
- Extended loan term: Spreads payments over more months
- Increase equity contribution: Reduces total financing needed
Don't proceed with tight cashflow scenarios. The restaurant must comfortably support loan payments during challenging periods. Tools like KitchenNmbrs can help model different financing scenarios before you commit.
💡 Calculation example adjustment:
€4,000 cashflow, €3,182 loan payment (125% = risky):
- Option 1: Reduce loan by €50,000 → €2,650 payment
- Option 2: Extend to 15 years → €2,372 payment
- Option 3: Add €100,000 equity → €2,119 payment
Now you've achieved a safe 150%+ ratio.
How do you calculate cashflow vs. loan capacity? (step by step)
Gather the real figures
Request the VAT returns and annual accounts from the past 2 years. Calculate the average monthly revenue and costs per category (food, personnel, fixed costs).
Calculate operating cashflow per month
Subtract from the monthly revenue: food cost, personnel costs, rent, energy and other operating costs. What's left is available for loan repayment.
Check the 150% rule
Your operating cashflow must be at least 150% of your monthly loan burden. Calculate this also for the worst months to account for seasonal fluctuations.
✨ Pro tip
Run your cashflow analysis using the restaurant's 3 weakest consecutive months from the past 18 months. If those numbers still support 150% loan coverage, you've found a financially sound acquisition.

Frequently asked questions
What constitutes a safe cashflow ratio for restaurant financing?
Operating cashflow should reach at least 150% of your monthly loan payment. This buffer accommodates tax payments, seasonal downturns, and unexpected expenses that inevitably arise.
Should depreciation factor into my cashflow calculations?
Never include depreciation in cashflow analysis. It's an accounting entry with no actual cash outflow. Focus exclusively on real expenses like food costs, payroll, rent, and utilities.
How do I verify the seller's financial claims?
Request VAT returns and bank statements spanning 24 months minimum. Sellers often cherry-pick their strongest months, so independent documentation proves actual performance. Without verified numbers, accurate cashflow analysis becomes impossible.
