Nearly 73% of restaurants struggle with food costs exceeding their target margins. You're facing the classic dilemma: raise prices or cut portions. Both paths impact your guests differently and carry distinct risks for profit and satisfaction.
Calculate the impact of both options
Smart decisions require side-by-side number comparisons. Each choice carries consequences that extend far beyond immediate costs.
💡 Example:
Your pasta carbonara costs €12 in ingredients, sells for €28 (excl. VAT €25.69).
- Current food cost: 46.7% (way too high)
- Target food cost: 32%
- You need to save €4 per portion
Option 1: Price increase
Price hikes are transparent but might spook customers. Calculate your minimum increase needed to hit that target food cost percentage.
💡 Price increase calculation:
For 32% food cost at €12 ingredients:
- Minimum price excl. VAT: €12 ÷ 0.32 = €37.50
- Price incl. VAT: €37.50 × 1.09 = €40.88
- Increase: from €28 to €41 = +€13 (46%)
Advantages of price increase:
- Portion size remains unchanged
- Customers receive full value
- Honest and straightforward approach
- Better margin per dish sold
Disadvantages of price increase:
- May drive away price-sensitive diners
- Makes competitors appear more affordable
- Dramatic jumps grab unwanted attention
⚠️ Watch out:
Price increases above 15% typically catch diners' attention. Consider rolling out increases across 2-3 months instead.
Option 2: Portion reduction
Shrinking portions flies under the radar initially, but hungry guests notice eventually. One of the most common blind spots in kitchen management is underestimating how quickly regular customers spot portion changes.
💡 Portion reduction calculation:
For 32% food cost at €25.69 selling price:
- Maximum ingredient costs: €25.69 × 0.32 = €8.22
- Current costs: €12
- Must save: €12 - €8.22 = €3.78 (31.5% reduction)
Advantages of portion reduction:
- Menu prices stay put
- Changes aren't immediately obvious
- Competitive pricing advantage maintained
- Reduces food waste naturally
Disadvantages of portion reduction:
- Disappointed diners leave unsatisfied
- Negative reviews about small portions
- Perceived value takes a hit
- Difficult to reverse later
The hybrid approach
Smart operators often blend both strategies: modest price bump plus minor portion tweak. This distributes the financial impact more evenly.
💡 Hybrid example:
Split the difference for gentler adjustments:
- Raise price: €28 → €32 (+€4)
- Reduce ingredients: €12 → €10.24 (-€1.76)
- New food cost: €10.24 ÷ €29.36 = 34.9%
Result: workable food cost without shocking changes.
Which dishes to tackle first?
Target your top sellers with the worst margins first. These deliver maximum impact on overall profitability.
- Priority 1: High-volume dishes with food cost >40%
- Priority 2: Medium sellers with food cost >35%
- Priority 3: Low-volume items for later review
⚠️ Watch out:
Avoid adjusting everything simultaneously. Customers will definitely notice wholesale changes and might defect to competitors.
Test and monitor the results
After making adjustments, track the effects closely. Watch sales data, customer satisfaction scores, and online reviews.
Key metrics to track:
- Weekly portion sales volume
- Online review sentiment and feedback
- Total dish revenue performance
- Repeat customer ordering patterns
Management systems help you spot the impact of adjustments on food costs immediately, allowing quick pivots if results don't match expectations.
How do you make the right choice? (step by step)
Calculate your current food cost
Add up all ingredient costs and divide by your selling price excl. VAT. Multiply by 100 for the percentage. This is your starting point.
Determine your desired food cost
For most restaurants this is between 28-35%. Choose a realistic percentage that fits your type of business and competitive position.
Calculate both scenarios
Calculate the required price increase and the required portion reduction. Compare which option is most realistic for your situation.
Test with one dish
Start with your best-selling dish with the worst margin. Monitor sales figures and guest feedback for 2-3 weeks.
Evaluate and adjust
See if the adjustment works as expected. Too much customer loss? Consider the hybrid approach or smaller steps.
✨ Pro tip
Test your changes on 2-3 high-volume dishes over 30 days before expanding. Monitor daily sales and review sentiment to catch problems early.

Frequently asked questions
How much price increase do guests notice?
Increases up to 10-15% typically slip by unnoticed, especially with gradual rollouts. Anything above 20% becomes risky for customer retention.
Can I reduce portions without guests noticing?
Small cuts (5-10%) often go undetected. Larger reductions get spotted quickly, particularly with premium ingredients like meat or seafood.
What if my competitors stay cheaper?
Emphasize added value through superior quality, ambiance, or service. Price isn't everything for most diners. Clearly communicate why your dish justifies the premium.
How often can I adjust prices?
Limit regular menu changes to 2-3 times annually maximum. More frequent adjustments confuse both guests and staff. Seasonal specials can change more often.
Should I warn customers about adjustments?
Price increases don't need advance notice unless they're dramatic. For obvious portion cuts, spin it positively: 'perfectly portioned' or 'sustainable sizing.'
Which costs more long-term: losing customers or thin margins?
Thin margins kill restaurants faster than moderate customer turnover. A 5% customer loss with healthy margins beats keeping everyone at break-even pricing.
