Picture this: your restaurant's about to shift from quiet winter months to bustling summer season. Your P&L becomes your roadmap, showing exactly where you stand financially and how to prepare for the rush. With the right numbers, you steer consciously toward higher profit instead of just working harder.
Analyze your current P&L as a starting point
Before you can steer, you need to know where you stand. Take your P&L from the past 3 months (low season) and compare it with the same period last year during high season.
💡 Example comparison:
Restaurant De Kust - March vs August last year:
- Revenue March: €45,000 vs August: €78,000
- Food cost March: 32% vs August: 28%
- Labor costs March: 35% vs August: 31%
- Net profit March: 8% vs August: 18%
Bottom line: With higher revenue, your percentages drop due to better distribution of fixed costs.
Critical ratios that change during seasonal transition
Not all cost items rise proportionally with your revenue. That's why your percentages shift and your P&L changes.
- Food cost: Can drop through better purchasing (larger volumes) and less waste (higher turnover)
- Labor costs: Rise in absolute terms, but drop as a percentage through better productivity
- Fixed costs: Stay the same, so drop dramatically as a percentage of revenue
- Variable costs: Rise proportionally (energy, dishwashing, packaging)
Optimize food cost for high season
Your food cost can drop 3-5 percentage points through smarter purchasing and less waste. This has enormous impact on your profit.
💡 Impact calculation:
At €80,000 revenue per month during high season:
- Food cost from 32% to 28% = 4 percentage point difference
- Savings: €80,000 × 0.04 = €3,200 per month
- Over 4 months of high season: €12,800 extra profit
How do you achieve this? Larger purchases get you better prices. Higher turnover means less spoilage. Better planning means less overproduction.
Keep labor costs in balance
More revenue means more staff, but not proportionally. An experienced team can handle 40-60% more revenue without proportionally more hours.
⚠️ Watch out:
Don't hire staff too early. Better to start slightly understaffed than to have too much labor cost too soon. You can always add more hands.
Aim for 28-32% labor costs during high season. During low season this can be 35-40% due to lower revenue.
Use fixed costs as a lever
Your rent, insurance, and depreciation stay the same. With higher revenue, these automatically become lower percentages. This becomes one of the most common blind spots in kitchen management - owners don't realize how powerful this lever really is.
💡 The multiplier effect:
Fixed costs €8,000 per month:
- At €40,000 revenue = 20% of revenue
- At €80,000 revenue = 10% of revenue
- Difference: 10 percentage points more profit!
Monthly P&L monitoring during transition
Track your P&L every month and compare with last year. Pay special attention to these signals:
- Food cost rises: Check if suppliers raised prices or if there's more waste
- Labor costs too high: Maybe you expanded too early or have too much overtime
- Revenue stalls: Competition active or another setback?
A system like automated food cost tracking helps you spot signals in your P&L faster.
Use P&L as a management tool (step by step)
Analyze your baseline
Compare your P&L from the past 3 months with the same period last year. Note the differences in food cost, labor costs, and net profit percentages.
Set target percentages
Determine realistic goals for high season: food cost 28-32%, labor costs 28-32%, total costs max 85% of revenue for healthy profit.
Monitor weekly
Check your key ratios every week. If deviations exceed 2 percentage points, take immediate action: adjust prices or cut costs.
Adjust based on trends
If your food cost rises for 2 weeks straight, check your supplier prices. If labor costs are too high, revise your planning before it becomes a habit.
✨ Pro tip
Track your food cost percentage against last year's high season numbers every 10 days during the 6-week transition period. If you're running more than 2 percentage points higher than your target, you're bleeding €2,000+ per month on an €80k revenue base.

Frequently asked questions
How often should I check my P&L during seasonal transition?
At least weekly, ideally every few days for the key ratios. You want to be able to adjust quickly if something goes the wrong way.
Which P&L ratio is most important to watch?
Food cost percentage. This changes fastest and has direct impact on your profit. A 2 percentage point increase can cost thousands of euros per month.
What if my labor costs get too high?
First check if it's due to overtime or too much staff. You can address overtime directly, but too much staff requires more planning for next month.
How do I prevent my food cost from rising during busy periods?
Through better portion control and less waste. More business often means rush, and rush leads to larger portions and more mistakes. Train your team on this.
Should I adjust my menu prices for high season?
Only if your supplier costs have risen. Use your P&L to see if your current prices deliver enough margin at the new cost structure.
What's the biggest mistake restaurants make with fixed costs during seasonal transitions?
They don't factor in the multiplier effect early enough. Many owners focus only on variable costs while missing that fixed costs become their biggest profit driver during high season.
