How do I calculate the margin of a three-course menu deal compared to à la carte sales?

📝 KitchenNmbrs · updated 13 Mar 2026

Nearly 73% of restaurants offer fixed-price menu deals, yet most can't accurately compare their profitability to à la carte sales. Menu deals might seem less profitable at first glance, but they often drive higher margins through increased order volume. Understanding the real math behind both approaches determines which strategy actually puts more money in your pocket.

Why menu deals turn out differently than expected

A three-course menu for €42.50 seems attractive. À la carte sales would reach €55.00. But does that automatically mean less profit? Not necessarily.

⚠️ Note:

Menu deals often have a different cost structure. Guests might choose cheaper appetizers, or you use different portion sizes.

Calculate the cost price of your menu deal

For a fair comparison, you need to know what each part of your menu actually costs. Not what it would cost individually, but what guests actually choose.

💡 Example menu deal:

Three-course menu €42.50 (incl. 9% VAT = €38.99 excl. VAT)

  • Appetizer: tomato soup (€1.80 cost price)
  • Main course: chicken with vegetables (€7.20 cost price)
  • Dessert: tiramisu (€2.40 cost price)

Total cost price: €11.40

Margin: €38.99 - €11.40 = €27.59 (70.8%)

Compare with actual à la carte sales

Now you need to calculate what the same guest would order with à la carte sales. Note: this is often different from your most expensive options. One of the most common blind spots in kitchen management is assuming guests will order the same items at full price that they choose in a fixed menu.

💡 À la carte scenario:

Same guest orders à la carte (what they would likely choose):

  • Main course: chicken €22.00 (€7.20 cost price)
  • No appetizer or dessert (too expensive)

Sales excl. VAT: €20.18

Margin: €20.18 - €7.20 = €12.98 (64.3%)

The comparison: menu vs. à la carte

Now you can put both scenarios side by side:

  • Menu deal: €27.59 margin per guest
  • À la carte sales: €12.98 margin per guest
  • Difference: €14.61 more margin with menu deal

In this example, you earn more with the menu deal, despite the lower sales price. The guest orders more items than they would à la carte.

⚠️ Note:

This only works if your menu deal encourages guests to order more than they would otherwise. If they would order three courses anyway, you lose money.

Factors that influence the comparison

Different elements make menu deals more or less profitable:

  • Seasonal ingredients: Cheaper seasonal products make menu deals more attractive
  • Choice options: More options mean guests can choose cheaper alternatives
  • Portion sizes: Smaller portions in menu deals can reduce cost price
  • Purchasing advantages: Larger volumes of the same ingredients can be cheaper

💡 Seasonal example:

Autumn menu with seasonal products:

  • Pumpkin soup (€1.20 instead of €1.80 in winter)
  • Wild stew (€6.80 instead of €8.50 for beef)
  • Apple pie (€1.90 instead of €2.40 for exotic fruit)

Seasonal cost price: €9.90 (€1.50 cheaper)

Menu deals that don't work

Menu deals can also backfire. Watch for these signals:

  • High food cost: If your menu deal comes in above 35% food cost, you're probably losing money
  • Cannibalization: Guests who would normally order more expensive items now choose the deal
  • Operational pressure: Complex menus cost more time and staff

Food cost tracking tools help monitor these calculations automatically, so you quickly see which menu composition generates the most revenue.

How do you calculate the margin of a menu deal? (step by step)

1

Calculate cost price of menu deal

Add up all ingredient costs of what guests actually choose in your menu deal. Not the most expensive options, but the average choices. Don't forget to include garnishes and side dishes.

2

Calculate cost price of à la carte sales

Calculate what the same guest would order with à la carte sales. Usually fewer courses than in a menu deal. Use realistic assumptions, not your most expensive dishes.

3

Compare the margins

Subtract the cost price from the sales price (excl. VAT) for both scenarios. The scenario with the highest absolute margin per guest is more profitable, regardless of the percentage.

✨ Pro tip

Track your menu deal selections over 2 weeks to get accurate choice percentages. If 75% pick soup and 25% choose salad, use weighted average costs (soup €1.80 x 0.75 + salad €2.20 x 0.25 = €1.90) rather than individual item costs.

Frequently asked questions

Should I calculate with the price including or excluding VAT?

Always excluding VAT. The price on your menu includes 9% VAT, but for margin calculations you work excl. VAT. So €42.50 incl. becomes €38.99 excl. VAT.

What if guests always choose the most expensive options in my menu?

Then your menu deal will probably become unprofitable. Monitor which choices guests make and adjust your menu accordingly. You can also limit the options to comparable cost prices or redesign the selection.

How often should I recalculate menu deal profitability?

With every menu change and at least every season. Ingredient prices fluctuate, so does your margin. Check especially after supplier price increases or with new seasonal menus, as cost structures shift significantly.
