A restaurant takeover's net present value tells you if your 10-year investment makes financial sense before you sign anything. Too many buyers get caught up in current profits and forget that €100 today buys more than €100 will in five years. The math separates smart investments from expensive mistakes.
What is net present value?
Net present value (NPV) shows what all your future cash flows are worth right now. It factors in inflation and the reality that money sitting in your pocket today has more buying power than the same amount years down the road.
💡 Example:
Restaurant costs €300,000. Expected yearly profit: €50,000. Discount rate: 8%.
- Year 1: €50,000 / 1.08 = €46,296
- Year 2: €50,000 / 1.08² = €42,867
- Year 10: €50,000 / 1.08¹⁰ = €23,160
Add all years, subtract investment = NPV
The formula for NPV
The basic formula looks like this:
NPV = Σ (Cash flow year n / (1 + discount rate)ⁿ) - Initial investment
Breaking it down:
- Cash flow = net profit + depreciation per year
- Discount rate = your required return (usually 6-12% for restaurants)
- n = the year (1, 2, 3... to 10)
- Initial investment = purchase price + renovations + working capital
Figuring out cash flows
Your restaurant's yearly cash flow includes:
- Net profit: revenue minus all operating expenses
- Depreciation: these paper losses don't actually cost you cash
- Owner's salary: what you pay yourself for running the place
💡 Example cash flow calculation:
Restaurant pulling €800,000 yearly revenue:
- Net profit: €40,000
- Owner's salary: €45,000
- Depreciation: €15,000
Total cash flow: €100,000 per year
Picking your discount rate
The discount rate reflects how much return you need to make this worthwhile. For restaurants, think:
- 6-8%: rock-solid, established business
- 8-12%: typical restaurant deal
- 12-15%: risky buy or unproven concept
⚠️ Note:
More risk means you need higher returns. A restaurant in a sketchy neighborhood needs a steeper discount rate than a proven business in a great location.
Residual value after 10 years
Your restaurant will still be worth something after the 10-year period. This leftover value gets added to your NPV calculation.
Common ways to estimate this:
- Book value: original price minus total depreciation
- Market value: what similar businesses sell for now
- Terminal value: year 10 cash flow divided by discount rate (assuming you keep running it)
💡 Example residual value:
Year 10 cash flow: €100,000. Discount rate: 8%.
Terminal value: €100,000 / 0.08 = €1,250,000
Present value: €1,250,000 / 1.08¹⁰ = €579,000
Reading your NPV results
Your calculation tells you everything you need to know:
- NPV > 0: investment beats your required return
- NPV = 0: investment hits exactly your target return
- NPV < 0: investment doesn't meet your profitability standards
Higher NPV numbers mean better investment opportunities.
Real-world calculation tips
Ground your projections in reality and factor in:
- Seasonal ups and downs in revenue
- Rising costs (inflation, wages, rent bumps)
- Equipment repairs and kitchen upgrades
- New competitors moving in
And the kind of thing you only learn after closing your first month at a loss: always stress-test your numbers with different scenarios. Run your NPV with pessimistic, realistic, and optimistic cash flows.
⚠️ Note:
Conservative estimates save you from nasty surprises. Calculate using 80% of projected revenue and 120% of estimated costs for a safety cushion.
How do you calculate the NPV of a restaurant takeover?
Determine the annual cash flow
Calculate net profit + owner's salary + depreciation per year. Use the seller's figures, but verify them with your own research. Request at least 3 years of financial statements.
Choose the right discount rate
Determine what return you want to achieve at minimum. For stable restaurants 6-8%, for risky takeovers 12-15%. The higher the risk, the higher the discount rate.
Calculate the present value per year
Divide each annual cash flow by (1 + discount rate)^year. Year 1: cash flow/1.08¹, year 2: cash flow/1.08², and so on until year 10.
Add the residual value
Estimate what the restaurant is worth after 10 years. Calculate its present value by dividing by (1 + discount rate)¹⁰.
Subtract the investment
Add up all present values and subtract the total investment (purchase price + renovation + working capital). Is the result positive? Then the takeover is profitable.
✨ Pro tip
Run a 30% revenue drop scenario for years 4-6 to stress-test your NPV against economic downturns. This reveals if your acquisition can weather financial storms and still hit your 10-year return targets.

Frequently asked questions
What discount rate should I use for a restaurant?
For stable, established businesses use 6-8%. Average restaurants warrant 8-12%. High-risk situations like new concepts or poor locations require 12-15%. Higher risk always demands higher returns.
How reliable are the seller's figures?
Always request three years of financial statements and have an accountant review them. Many sellers highlight their best years or omit certain costs. Calculate conservatively with 80% of promised revenue.
Should I include my own salary in the cash flow?
Yes, your owner's salary represents part of the investment return since you're contributing your time. Use a realistic salary for your management role, typically €40,000-€60,000 for restaurant managers.
What if the NPV is negative?
A negative NPV means the investment won't achieve your desired return. You can negotiate a lower purchase price, reduce your discount rate expectations, or walk away from the deal entirely.
