Different menus for lunch and dinner can dramatically change your restaurant's profitability. Lunch guests spend €12-18 on average while dinner guests spend €25-45. Calculating the margin impact helps you see which service drives real profit.
Why lunch and dinner margins differ so much
Your fixed costs don't change between services - rent, insurance, and base staffing stay constant. But revenue patterns shift dramatically between dayparts.
- Lunch guests: Quick turnover, lower checks, more covers per hour
- Dinner guests: Longer stays, higher checks, fewer covers per hour
- Service expectations: Lunch demands speed and value, dinner allows premium pricing
? Example:
Restaurant with 40 seats, lunch (12:00-15:00) and dinner (18:00-22:00):
- Lunch: 60 covers × €15 average = €900 in 3 hours
- Dinner: 50 covers × €32 average = €1,600 in 4 hours
- Hourly revenue: Lunch €300 vs. Dinner €400
Dinner generates €100 more per hour
Track your actual daypart performance
You can't optimize what you don't measure. Start by separating your lunch and dinner numbers completely.
Step 1: Collect 4 weeks of data per service
- Revenue by daypart
- Cover counts per service
- Average spend per guest
- Food costs (different dishes = different percentages)
Step 2: Calculate true costs per daypart
- Labor costs per service hour
- Utilities and energy per operating hour
- Equipment usage costs
? Sample calculation:
Daily comparison: Lunch (3 hours) vs. Dinner (4 hours):
LUNCH SERVICE:
- Revenue: €900
- Food cost (25%): €225
- Labor: €180 (3 hours × €60/hour)
- Utilities: €45
- Net profit: €450 (50%)
DINNER SERVICE:
- Revenue: €1,600
- Food cost (30%): €480
- Labor: €240 (4 hours × €60/hour)
- Utilities: €60
- Net profit: €820 (51%)
Hourly profit: Lunch €150 vs. Dinner €205
Model different menu strategies
Separate menus let you price strategically for each service. Lower lunch prices can drive volume while premium dinner pricing maximizes revenue per guest.
I've seen restaurants make a mistake that costs them €200-400 monthly by not tracking how menu changes affect each daypart differently - lunch volume responds to price cuts while dinner guests often ignore small increases.
Strategy A: Reduce lunch prices 10%
- Current lunch average: €15
- New lunch average: €13.50
- Expected volume boost: +20% more covers
⚠️ Note:
Volume increases are estimates - test with limited-time offers before changing your entire menu structure.
Strategy B: Increase dinner prices 15%
- Current dinner average: €32
- New dinner average: €36.80
- Expected volume drop: -5% fewer covers
? Revenue impact:
Lunch pricing strategy (-10% price, +20% volume):
- Current: 60 × €15 = €900
- New: 72 × €13.50 = €972
- Daily increase: €72
Dinner pricing strategy (+15% price, -5% volume):
- Current: 50 × €32 = €1,600
- New: 47.5 × €36.80 = €1,748
- Daily increase: €148
Combined daily boost: €220
Food cost variations between services
Lunch and dinner naturally have different food cost percentages. Don't use the same targets for both services.
- Lunch dishes: Salads, pasta, sandwiches (20-28% food cost)
- Dinner dishes: Steaks, seafood, complex preparations (28-35% food cost)
- Portion differences: Lunch portions typically 15-20% smaller
Track these percentages separately so you understand which service actually drives more profit.
Testing and rolling out changes
Start small before overhauling your entire menu structure.
Week 1-2: Limited testing
- Change prices on 3-4 popular dishes per service
- Track sales volume and guest feedback
- Monitor online reviews for price complaints
Week 3-4: Analyze results
- Compare to same period previous year
- Calculate actual margin impact per daypart
- Decide whether to expand or adjust strategy
How do you calculate the margin impact? (step by step)
Gather 4 weeks of data per daypart
Record revenue, number of covers, and average check value separately for lunch and dinner. This gives you an accurate picture of the current situation per daypart.
Calculate costs per hour per daypart
Divide your staff costs, energy costs, and food cost by the number of hours you're open. Lunch is often 3 hours, dinner 4 hours.
Model different pricing scenarios
Test on paper what happens if you make lunch 10% cheaper and dinner 15% more expensive. Calculate with realistic volume effects (+20% lunch, -5% dinner).
✨ Pro tip
Test price changes on your top 5 lunch dishes over 3 weeks before changing everything. Lunch guests respond faster to pricing than dinner guests, so you'll see volume changes within days.
