Energy costs can turn your seasonal menu upside down. If gas and electricity become 30% more expensive, your profit margin can suddenly evaporate without you noticing. Here's how to adjust your menu calculations and protect your bottom line.
Why energy costs affect your seasonal menu
Energy costs rank as the third largest expense after food and labor. For restaurants, they typically range between 3% and 8% of revenue. But not all dishes consume the same amount of energy.
- Slow-cooked dishes demand more gas and electricity
- Fried dishes consume significant energy heating oil
- Oven dishes cost more than grilled alternatives
- Cold dishes like salads and carpaccio remain energy-neutral
💡 Example:
Energy costs jump from €800 to €1,040 per month (+30%). With 2,000 covers per month:
- Was: €0.40 per plate
- Now: €0.52 per plate
- Difference: €0.12 per plate
Extra costs: €240 per month
Which dishes are hit hardest
Not all dishes face equal impact. Some consume dramatically more energy than others - a pattern we see repeatedly in restaurant financials where operators underestimate these differences.
High energy consumption:
- Stew (3+ hours simmering): +€0.25 per portion
- Spare ribs (2 hours oven): +€0.20 per portion
- Fried dishes: +€0.15 per portion
- Pizzas (hot oven): +€0.12 per portion
Low energy consumption:
- Grilled fish: +€0.05 per portion
- Salads: +€0.02 per portion
- Carpaccio: +€0.02 per portion
- Tartare: +€0.01 per portion
⚠️ Note:
Don't calculate with average energy costs per dish. A stew costs 10 times more energy than a salad.
Calculate your new cost price per dish
For each dish, add the extra energy costs to your existing cost price.
Formula for new cost price:
New cost price = Old cost price + Extra energy costs per portion
💡 Example stew:
Beef stew for €28.50 (incl. 9% VAT):
- Old cost price: €8.50
- Extra energy costs: €0.25
- New cost price: €8.75
- Selling price excl. VAT: €26.15
- New food cost: 33.5% (was 32.5%)
Your margin drops by 1 percentage point
Three strategies to restore your margin
If your food cost rises due to energy costs, you have three options:
1. Raise prices
- Advantage: margin stays the same
- Disadvantage: guests pay more
- Tip: do this selectively for energy-intensive dishes
2. Adjust menu mix
- Advantage: no price increases
- Disadvantage: less choice for guests
- Tip: promote energy-efficient dishes more
3. Optimize portion sizes
- Advantage: cost price decreases
- Disadvantage: guests get less
- Tip: only for overly generous portions
💡 Example price increase:
Restore stew margin from 33.5% to 32.5%:
- Desired cost price: €8.50 (32.5% of €26.15)
- Actual cost price: €8.75
- Difference: €0.25
- New selling price: €26.92 excl. VAT
- Menu price: €29.32 incl. VAT
Price increase: €0.82 per dish
Seasonal menu timing and energy costs
The timing of your seasonal menu can affect energy costs:
- Winter: more stews, slow cooking → higher energy costs
- Summer: more salads, cold dishes → lower energy costs
- Christmas: heavy oven use → peak costs
- Spring: balance between warm and cold
Plan your menu not just based on ingredients, but also on energy consumption.
⚠️ Note:
Energy contracts can change mid-season. Check your energy bill monthly and adjust your cost prices during major changes.
Track energy costs digitally
Manually recalculating all dishes takes considerable time. With a system like KitchenNmbrs, you can enter energy costs as a variable and automatically have your cost prices recalculated.
This saves hours of work with every energy price change and prevents calculation errors.
How do you recalculate your seasonal menu when energy costs rise?
Calculate your total energy cost increase
Compare your current energy bill with last year. Divide the difference by the number of covers per month to get the extra costs per plate.
Categorize dishes by energy consumption
Divide your dishes into: high consumption (stews, fried), medium (grill, quick frying) and low (salads, cold dishes). High consumption gets the most extra costs.
Recalculate cost price and food cost per dish
Add the extra energy costs to your existing cost price. Calculate your new food cost percentage. If this exceeds 35%, you need to take action.
Choose your strategy per dish
Raise prices on popular energy-intensive dishes, promote energy-efficient alternatives, or adjust portion sizes where possible.
Update your menu and communicate
Adjust prices on your menu and explain to your team why certain dishes became more expensive. Transparency helps with acceptance.
✨ Pro tip
Recalculate your energy-intensive dishes within 48 hours of receiving a bill showing 20%+ increases. Quick adjustments prevent 3-4 weeks of eroded margins that can cost you €500-800 in lost profit.

Frequently asked questions
How often should I adjust my menu for energy costs?
Check your energy bill monthly. Changes exceeding 15% warrant immediate cost price adjustments. For smaller fluctuations, you can wait until your next seasonal menu launch.
Can I pass energy costs on to guests without losing customers?
Yes, but do it strategically. Raise prices on energy-intensive dishes by €0.50-1.00 and simultaneously promote energy-efficient alternatives. Guests accept this better than blanket price increases across your entire menu.
What if my competitor doesn't raise their prices during energy spikes?
Focus on value communication rather than price matching. Explain that you choose quality preparation methods and sustainable practices. Many guests will accept slightly higher prices for superior dishes and transparency about your costs.
