Acquiring a competitor can strengthen your market position and generate extra revenue. But what does this mean for your margin? The impact depends on how many customers you take over, what costs come with it, and how you integrate operationally. In this article, you'll learn step-by-step how to calculate the financial impact before you make an offer.
Why calculating margin impact is crucial
When acquiring, you often look at revenue and customer base. But the real question is: how much extra profit does this generate? A competitor with €500,000 in revenue seems attractive, but if your operating costs rise by €400,000, you're only earning an extra €100,000.
⚠️ Watch out:
Many acquisitions fail because entrepreneurs only look at revenue. The margin impact determines whether an acquisition is profitable.
The three pillars of margin impact
With every acquisition, there are three factors that affect your margin:
- Extra revenue: How many customers do you take over and what do they spend?
- Extra costs: Staff, rent, purchasing, integration
- Synergy benefits: Economies of scale in purchasing, more efficient operations
The trick is to estimate these realistically, not optimistically.
Step 1: Calculate the acquired revenue
Not all of your competitor's customers will automatically come to you. Plan for a takeover rate of 60-80% in the first year.
💡 Example:
Competitor has €400,000 annual revenue, average €35 per bill, 11,400 customer visits per year.
- Expected takeover: 70% = 8,000 visits
- Your average bill: €32
- Extra revenue year 1: 8,000 × €32 = €256,000
Realistic scenario: €256,000 extra revenue
Step 2: Calculate extra operating costs
More revenue means more costs. Add up what comes with it:
- Food cost: 30% of extra revenue (at €256,000 = €76,800)
- Extra staff: Kitchen and service for busy periods
- Rent/location: If you take over a second location
- Marketing: To retain acquired customers
💡 Example cost calculation:
- Food cost (30%): €76,800
- Extra staff: €60,000
- Marketing costs: €15,000
- Other costs: €25,000
Total extra costs: €176,800
Step 3: Calculate synergy benefits
Through scaling, you can save costs:
- Purchasing: Larger volumes = better prices from suppliers
- Efficiency: Central prep, shared recipes
- Fixed costs: Spread administration and accounting over more revenue
Calculate conservatively: 2-5% cost savings on your total operation is realistic.
The margin impact formula
Now you can calculate the total margin impact:
Margin impact = Extra revenue - Extra costs + Synergy benefits - Acquisition costs
💡 Complete example:
- Extra revenue: €256,000
- Extra costs: €176,800
- Synergy benefits: €20,000
- Acquisition costs (depreciation): €15,000
Net margin impact: €256,000 - €176,800 + €20,000 - €15,000 = €84,200
Include risk factors
Also create a pessimistic scenario. What if only 50% of customers come over? Or if your extra staff costs more than expected?
⚠️ Watch out:
Always calculate a worst-case scenario. If that's still positive, the acquisition is probably wise.
Timing and cashflow impact
Margin impact isn't immediately visible. Plan for:
- Month 1-3: Integration costs, not all customers over yet
- Month 4-6: Operations stabilize, synergy benefits become visible
- Month 7-12: Full margin impact achieved
Plan sufficient cashflow for the first 6 months.
How do you calculate margin impact? (step by step)
Estimate realistic customer takeover
Calculate how many of the competitor's customers will likely come to you. Plan for 60-80% in the first year, not 100%. Multiply by your average bill amount for extra revenue.
Add up all extra costs
Calculate what the extra revenue costs: food cost (30%), extra staff, marketing to retain customers, and any location costs. Be realistic, not optimistic.
Calculate synergy benefits and ROI
Determine what cost savings are possible through scaling (purchasing, efficiency). Subtract acquisition costs and calculate the net margin impact per year.
✨ Pro tip
Always create three scenarios: optimistic (80% customer takeover), realistic (70%), and pessimistic (50%). If the pessimistic scenario is still positive, the acquisition is probably wise.

Frequently asked questions
How many customers do you typically take over from a competitor?
Realistically, 60-80% of customers in the first year. Some go to other businesses, others stop altogether. Never plan for 100% takeover.
What are typical acquisition costs for a food service business?
This varies widely: from €50,000 for goodwill and inventory to €300,000+ for a complete business with property. Depreciate this over 5-7 years for your margin impact calculation.
How long does it take to see the full margin impact?
Usually 6-12 months. The first months have integration costs and not all customers come over immediately. Plan sufficient cashflow for this period.
What synergy benefits are realistic?
Think about 2-5% cost savings on your total operation through better purchasing prices, more efficient planning, and shared fixed costs. More than 10% is usually too optimistic.
Should you close the competitor or keep it open?
That depends on location and overlap. Closing means taking customers to your location. Keeping it open means running two locations - different cost structure and complexity.
