What Is Contribution Margin? The Number That Drives Menu Decisions

Ask most restaurant owners which dish is "best" and they'll point to the one with the lowest food cost percentage. But the dish with the prettiest percentage isn't always the one paying your bills. The number that does that is contribution margin.

The definition

Contribution margin is simply the cash a dish contributes after its ingredient cost:

Contribution margin = selling price − ingredient cost

It's the money left over from each sale to cover rent, salaries, utilities — and profit.

Why it beats food cost % alone

Consider two dishes:

• A drink sells for 40 EGP at 25% food cost → contribution margin = 30 EGP.
• A steak sells for 320 EGP at 40% food cost → contribution margin = 192 EGP.

By food cost percentage, the drink looks "better." But the steak puts more than six times as much cash in your pocket per sale. Chase only low percentages and you'll under-sell your most valuable dishes.

How to use it

1. Calculate contribution margin for every item.

2. Multiply by how many you sell to get each dish's total contribution.

3. Rank them. The dishes at the top — high margin and high volume — are your real engine.

This is the foundation of the menu engineering matrix: popularity on one axis, contribution margin on the other. Together they tell you what to feature, fix, promote, or cut.

Don't do it by hand

Tracking price, cost, volume, and margin across a full menu is exactly the kind of work that's slow and error-prone in a spreadsheet. Wizzora calculates the contribution margin of every dish automatically and ranks your menu by what truly drives profit.
