Most restaurant owners think they can keep old menu prices after a takeover - that's a costly mistake. New suppliers and different recipes mean your margins shifted overnight. Calculate wrong and you'll bleed money for months before realizing what happened.
Why repricing after takeover matters so much
Taking over a restaurant means inheriting all existing contracts, suppliers, and recipes. But the actual costs rarely match what you expected:
- Suppliers bump prices after contract renewal
- Recipes use pricier ingredients than anticipated
- Portion sizes exceed your calculations
- Waste runs higher due to unfamiliar prep methods
⚠️ Watch out:
Many entrepreneurs stick with old menu prices and discover after 6 months they're losing money on popular dishes.
Step 1: Calculate actual cost price per dish
Start with your 10 top-selling dishes. Each dish requires:
- All ingredients with precise quantities per portion
- Current purchase prices from your suppliers
- Waste percentage per ingredient
- Packaging costs (for delivery/takeaway)
The formula for cost price per dish:
Cost price = Σ(Ingredient × Quantity × Current price per kilo)
💡 Example cost price calculation:
Steak with fries (old menu price €28.50):
- Steak 220g: €32/kg → €7.04
- Fries 200g: €2.50/kg → €0.50
- Sauce, butter, garnish: €1.20
- Packaging (for delivery): €0.35
Total cost price: €9.09
Step 2: Calculate current and target food cost
Now compare actual cost price with your current selling price:
Current food cost % = (Cost price / Selling price excl. VAT) × 100
Remember: always calculate with price EXCLUDING VAT. At 9% VAT:
Price excl. VAT = Menu price / 1.09
💡 Example food cost calculation:
Steak €28.50 incl. VAT, cost price €9.09:
- Selling price excl. VAT: €28.50 / 1.09 = €26.15
- Current food cost: (€9.09 / €26.15) × 100 = 34.8%
For restaurants, 28-33% is standard. This dish costs too much.
Step 3: Calculate annual margin impact
From analyzing actual purchasing data across different restaurant types, I've found that annual projections reveal the true financial impact. Calculate the difference per dish and multiply by yearly sales:
Margin impact per year = Difference per portion × Annual portion count
For annual portions, use:
- Daily average (from previous owner's POS data)
- Working days per week
- 52 weeks per year
💡 Example margin impact:
Steak repriced from €28.50 to €32.00:
- Extra margin per portion: €3.50 / 1.09 = €3.21 excl. VAT
- Sales: 15 portions/day, 6 days/week
- Per year: 15 × 6 × 52 = 4,680 portions
Total margin impact: €3.21 × 4,680 = €15,025 per year
Step 4: Factor in demand loss from price increases
Higher prices typically reduce sales volume. Calculate conservatively with 10-20% demand loss for price increases above 15%:
Net margin impact = (New margin × Expected sales) - Old margin
⚠️ Watch out:
For price increases above 20%, demand loss can hit 30%. Test with a few dishes first before overhauling your entire menu.
Smart strategies for successful repricing
Repricing after takeover demands careful planning:
- Phase increases: Spread over 2-3 months, not all at once
- Communicate the takeover: Customers expect price adjustments with new ownership
- Upgrade quality: Better ingredients justify higher prices
- Reposition dishes: Move expensive items to less prominent menu spots
💡 Example phased repricing:
Steak from €28.50 to €32.00 in 3 steps:
- Month 1: €28.50 → €30.00 (+5.3%)
- Month 3: €30.00 → €31.00 (+3.3%)
- Month 6: €31.00 → €32.00 (+3.2%)
Total +12.3% but spread over 6 months.
Tools that streamline post-takeover repricing
Manually recalculating all cost prices takes weeks. Systems like KitchenNmbrs help you:
- Record all recipes digitally with exact cost prices
- Update supplier prices across all dishes instantly
- Test different pricing scenarios for margin impact
- Calculate optimal menu prices per dish
This way you'll see within a day instead of weeks which dishes need repricing and what it'll yield.
How do you calculate the margin impact of repricing? (step by step)
Calculate actual cost price per dish
List all ingredients with exact quantities and new purchase prices. Include cutting waste and packaging costs. Add everything up for the total cost price per portion.
Calculate current and desired food cost percentage
Divide cost price by selling price excluding VAT and multiply by 100. Compare with standard food cost (28-33% for restaurants). Determine which dishes need repricing.
Calculate new selling price and margin impact
Calculate minimum selling price for desired food cost. Multiply the difference per portion by annual sales numbers. Account for 10-20% demand loss for large price increases.

Frequently asked questions
How much can I increase prices after a takeover?
Up to 15% usually works, especially if you communicate the takeover clearly. Above 20%, demand can drop 20-30%. Phase large increases over several months to minimize customer shock.
What if my food cost comes out above 40%?
You're losing money on those dishes - repricing is urgent. Either adjust prices immediately or swap expensive ingredients for alternatives. At 40% food cost, there's barely enough left for labor and overhead.
Should I replace ingredients instead of raising prices?
Both approaches have trade-offs. Replacing ingredients maintains price points but risks changing taste profiles. Price increases preserve quality but may reduce customer volume. Test both strategies on select items first.
