Weekly menus directly impact your bottom line through strategic dish promotion. Smart selection guides customers toward your most profitable options. Menu engineering reveals exactly which dishes deserve the spotlight.

What is menu engineering?

Menu engineering analyzes dishes using two key metrics: how popular they are and how much profit they generate. Cross-referencing these factors shows you which items to push and which need fixing.

? Example menu engineering matrix:

Analysis of 4 main courses over 30 days:

Steak: 120 sold, food cost 28% → Star
Salmon: 90 sold, food cost 38% → Plow horse
Duck: 25 sold, food cost 26% → Puzzle
Pasta: 15 sold, food cost 42% → Dog

Featuring steak as your weekly special = higher profits

Calculate the margin impact per dish

Focus on absolute profit per portion rather than just food cost percentages. This number tells the real story about which dishes make you money.

Absolute profit formula:
Selling price excl. VAT - Ingredient costs = Absolute profit

? Example calculation:

Dish comparison:

Steak: €32.00 incl. VAT → €29.36 excl. - €8.20 = €21.16 profit
Salmon: €28.00 incl. VAT → €25.69 excl. - €9.75 = €15.94 profit

Result: €5.22 more profit per steak portion

Project the impact of your weekly menu

Estimate how many additional covers your featured dish will generate, then multiply by the profit difference. But don't forget about cannibalization effects.

⚠️ Note:

Account for cannibalization: promoting steak might reduce salmon sales. Calculate that lost profit too.

? Example impact calculation:

Weekly special: steak promotion

Additional steak portions: +40/week
Reduced salmon sales: -15/week
Net profit: (40 × €21.16) - (15 × €15.94) = €607.30/week
Monthly impact: €607.30 × 4.3 = €2,611 additional profit

Measure and adjust your strategy

Track actual sales after launching your weekly menu. Did the promoted dish perform as expected? Was your cannibalization estimate accurate?

From years of working in professional kitchens, I've seen how small menu adjustments create massive profit swings. Tools like KitchenNmbrs automatically track food costs per dish, making these calculations much faster.

How do you calculate the margin impact of a weekly menu?

Analyze your current menu

Calculate the absolute profit per portion for each main course (selling price excl. VAT minus ingredient costs). Also count how many you sell per week.

Choose your weekly menu dish

Select a dish with high absolute profit that isn't your best-seller yet. This offers the most growth potential.

Estimate the shift in sales

Project how much extra of your weekly menu you'll sell and how much less of other dishes. Multiply by the absolute profit per dish.

Measure the actual impact

After a week, compare your actual sales figures with your projection. Adjust your next weekly menu strategy based on this.

✨ Pro tip

Track your top 8 dishes over the next 14 days, then calculate absolute profit per portion for each. The highest-margin item that isn't already your bestseller becomes your ideal weekly special candidate.

Frequently asked questions

Should I always choose my most expensive dish as the weekly menu?

No, select the dish with highest absolute profit per portion, not necessarily the priciest option. A moderately-priced dish with low ingredient costs often generates more profit than expensive items with high food costs.

How do I prevent my weekly menu from cannibalizing my other dishes?

Pick a dish that complements rather than competes with your popular items. If steak already sells well, consider featuring fish or vegetarian options as your weekly special.

How long should I keep a weekly menu?

Typically 1-2 weeks works optimal. This gives you enough time to measure real impact while keeping guests interested in your next selection.

Can I promote multiple dishes at once?

Yes, but limit yourself to 2-3 maximum. Too many featured items dilute the promotional impact and make it harder to track which dishes actually drove the results.

What if my weekly special has seasonal ingredient price fluctuations?

Recalculate your absolute profit margins monthly during peak season changes. A dish that's profitable in summer might lose money when ingredient costs spike in winter.

Should I offer a discount on my weekly menu?

Not necessarily required. Strategic menu placement, server recommendations, and appealing descriptions often work just as effectively without cutting into your margins.
