I've seen too many restaurant buyers pay double what they should've - and it nearly bankrupted them. Most entrepreneurs trust their gut instead of hard numbers, then spend years trapped in debt. Here's how to calculate exactly what you can afford to pay.
The basics: revenue and profit determine value
A restaurant's worth equals the profit it generates. Simple rule: never buy a business that takes longer than 3-4 years to pay for itself. You'll be drowning in loan payments otherwise.
💡 Example:
Restaurant with €400,000 annual revenue:
- Net profit: €60,000 per year
- Maximum price at 4 year payback period: €240,000
- At 3 years: €180,000
Pay €300,000? You're looking at 5 years to recover your investment.
Verify the actual numbers, ignore the sales pitch
Seller claims €500,000 revenue? Demand three years of VAT returns and bank statements. Most sellers inflate numbers or project their best month across twelve.
⚠️ Watch out:
Focus on the last 12 months of actual revenue, not cherry-picked periods. COVID, renovations, and seasonal fluctuations can distort the real picture.
Calculate your true operating costs
Revenue without costs tells you nothing. Here's what you're really spending:
- Rent: typically 8-12% of revenue
- Labor: including your salary, usually 35-45%
- Food costs: generally 28-35%
- Utilities, insurance, maintenance: 8-12%
- Equipment depreciation: 3-5%
What remains is your actual profit - the money available for loan payments.
💡 Calculation example:
Restaurant €400,000 annual revenue:
- Rent: €40,000 (10%)
- Labor: €160,000 (40%)
- Food costs: €120,000 (30%)
- Other expenses: €40,000 (10%)
Actual profit: €40,000 per year
Base calculations on your operating model
Maybe you'll work 70 hours a week while the current owner works 40. Perhaps you have different staffing plans. Calculate using your projected costs, not theirs.
Critical questions to answer:
- How many hours will you personally work?
- What's your time worth per hour?
- Can you renegotiate the lease terms?
- Are there pending maintenance issues?
Maximum price calculation methods
Two proven approaches for determining your ceiling:
Method 1: Payback period
Maximum price = Annual profit × 3 to 4 years
Method 2: Revenue multiple
Small restaurants: 0.3 to 0.6 × annual revenue
Profitable establishments: 0.4 to 0.8 × annual revenue
💡 Both methods applied:
Restaurant €300,000 revenue, €45,000 profit:
- Method 1: €45,000 × 3.5 = €157,500
- Method 2: €300,000 × 0.5 = €150,000
Your maximum offer: approximately €150,000
Factor in additional acquisition costs
The purchase price isn't your only expense:
- Legal and notary fees: €3,000-€8,000
- Renovations: always budget more than estimated
- Working capital: cash for initial operating months
- Property transfer tax: 2% on real estate purchases
⚠️ Watch out:
Reserve €30,000-€50,000 for first-year surprises. Based on real restaurant P&L data, every acquisition involves unexpected expenses.
Your financing capacity sets the limit
You can't pay more than you can finance. Banks typically fund 70% of the purchase price maximum. You'll need to cover the remainder.
Formula:
Maximum purchase price = (Your cash / 0.30) if bank finances 70%
Got €60,000 in cash? Your ceiling is €200,000 (€60,000 / 0.30).
How do you calculate the maximum price? (step by step)
Gather the real numbers
Demand the VAT returns and bank statements from the last 3 years. Calculate the average of the last 12 months. Don't believe any verbal promises about revenue.
Calculate net profit
Subtract all costs from revenue: rent, staff, purchases, energy, insurance. Calculate based on your situation, not the current owner's. Also include your own salary as a cost.
Determine your maximum bid
Multiply the annual profit by 3-4 years for the payback period. Also check if this fits within your financing options. Keep €30,000-€50,000 aside for unexpected costs.
✨ Pro tip
Get your accountant to audit the seller's books within 72 hours of receiving them. This €800 investment can reveal hidden liabilities that could cost you €50,000+ down the road.

Frequently asked questions
What if the seller won't show financial records?
Walk away immediately. You're essentially buying blind without verified numbers. Legitimate sellers always maintain proper records and share them transparently with serious buyers.
Can I pay more if I believe I can boost revenue?
Base your offer on current performance, not projected improvements. Your optimistic plans might fail, but the loan payments remain. Treat revenue increases as potential upside, never as guaranteed income.
How do I verify if the reported profit is accurate?
Check whether the owner included a realistic salary for themselves in the expenses. Many business owners omit their own compensation, artificially inflating the profit margins.
Should I include inventory value in my maximum bid?
Add inventory costs to your total investment calculation, not your business valuation. Have equipment professionally appraised since sellers typically overvalue kitchen assets and furnishings.
Are loss-making restaurants always bad investments?
Not necessarily, but they require extreme caution and deep analysis. You must identify the specific loss drivers and confirm you can realistically fix them before proceeding.
What's the biggest mistake buyers make in valuation?
Falling in love with the location or concept instead of focusing on numbers. Emotional decisions lead to overpaying - stick to your calculated maximum regardless of how perfect the restaurant seems.
