Most restaurants leave money on the table with awkward pricing, while smart operators round up to maximize profit. That €0.40 jump from €16.50 to €16.90 doesn't register with guests, but it can generate hundreds in extra annual revenue. You'll discover exactly how much rounding impacts your bottom line.
Why rounding up works
Guests expect 'nice' prices on menus. €16.90 doesn't feel psychologically pricier than €16.50, yet it delivers 2.4% more revenue. This extra cash flows almost directly to profit since your fixed costs remain unchanged.
💡 Example:
Your current steak costs €16.50. You're considering moving to €16.90.
- Difference per portion: €0.40
- At 20 steaks per week: €8.00 extra
- Per year: €416 extra revenue
Since ingredient costs stay the same, this flows almost entirely to profit.
The formula for margin impact
Extra revenue from rounding has a bigger effect on profit than most operators realize. And here's the math:
Extra profit = (New price - Old price) × Number of sales × Work weeks
The magic happens because ingredient costs stay fixed. So that extra €0.40 goes almost entirely to profit, minus VAT.
💡 Calculation example:
Pasta from €14.20 to €14.90 (difference €0.70):
- Sales: 35 pastas per week
- Extra per week: €0.70 × 35 = €24.50
- Per year (50 work weeks): €1,225
- Excl. VAT: €1,124 extra profit
One dish nets you €1,124 more annually, with zero additional costs.
Which prices are optimal to round
Not all rounding delivers equal results. Target these price points:
- From €X.20-€X.50 to €X.90: Maximum psychological impact
- From €X.00 to €X.50: Less noticeable than jumping to €X.90
- Avoid €X.95 or €X.99: Feels cheap in restaurant settings
- Watch out for big jumps: From €12.50 to €14.90 is too aggressive at once
⚠️ Heads up:
Test rounding first on your top-selling dishes. If those perform well, you can roll out to other items. Never raise all prices simultaneously.
Impact on different dishes
Margin impact varies by dish type and sales frequency. Based on real restaurant P&L data, high-volume items deliver the biggest wins:
💡 Impact comparison:
Rounding of €0.50 per dish, at different sales volumes:
- Top seller (40/week): €1,000 extra per year
- Average dish (15/week): €375 extra per year
- Slow mover (5/week): €125 extra per year
So prioritize your most popular dishes for maximum impact.
Timing of price adjustments
Your timing affects how guests react to changes:
- Start of season: Guests expect new menus
- After holidays: Less noticeable than mid-season
- With menu refresh: Rounding goes unnoticed among other changes
- Avoid busy periods: No price changes during Christmas or summer rush
Plan your rounding strategically. A fresh menu is perfect cover for rounding prices up without detection.
How do you calculate margin impact? (step by step)
Determine your new rounded prices
Choose your current prices you want to round. Focus on dishes between €X.20 and €X.60 - you can bring those to €X.90. Note the difference per dish.
Count your weekly sales per dish
Check in your POS system how much you sell per week of each dish you want to adjust. Take the average of the last 4-6 weeks for a realistic picture.
Calculate the annual impact
Multiply: (new price - old price) × weekly sales × 50 work weeks. This gives you the extra revenue per year. Subtract 9% VAT from this for the net impact on your profit.
✨ Pro tip
Test your rounding strategy on Tuesday-Thursday first, then expand to weekends after 3 weeks if sales hold steady. Weekend diners are typically less price-sensitive but weekday testing gives you cleaner data.

Frequently asked questions
Will guests notice if I round prices up?
Small rounding (€0.40-€0.70) usually goes unnoticed, especially with menu updates. From €16.50 to €16.90 doesn't feel much pricier than the original.
Which dishes should I round first?
Start with your top-selling dishes. Those deliver the biggest profit impact. If those perform well after 2-3 weeks, you can expand to other items.
How much can I raise without losing customers?
Stay under 5% increase at a time. From €16.00 to €16.90 (5.6%) is often still acceptable, but anything over 10% becomes risky.
Should I adjust all prices at once?
Never adjust everything simultaneously. Test first with 3-5 popular dishes and monitor sales for 2-3 weeks before expanding.
How do I calculate the impact on my food cost percentage?
Your food cost percentage improves because selling price rises while ingredient costs stay fixed. From €16.50 to €16.90 improves food cost by about 2.4%.
What's the difference between rounding to €X.50 vs €X.90?
€X.90 endings feel more premium and generate higher revenue per dish. €X.50 is safer for price-sensitive items but delivers smaller gains.
How do I track if rounding is hurting my sales volume?
Monitor weekly sales data for each rounded item over 4-6 weeks. If volume drops more than 3-5%, consider reverting or testing a smaller increase.
