How Do You Calculate Ideal Food Cost Percentage?

Well, if you want to know whether your restaurant business is on track, then you have to have some metric with which you can compare your food cost percentage.

To do so, compare your actual food cost, which you have calculated above with your ideal food cost.

The calculation of the ideal food cost percentage is pretty much similar to actual food cost percentage, except it does not take into account your beginning and ending inventories and consider the total costs and sales associated with each dish or menu item.

Ideal food cost percentage = (total cost per menu item)/(total sales per menu item)

Remember that when you are working with ideal costs, you suppose that there is no food waste and theft in your restaurant.

Total Sales Per Menu Item = Sales Price x Weekly Amount Sold

Examples for your understanding

The calculation for actual food cost percentage:

Food cost percentage = (Beginning Inventory + Purchases – Ending Inventory)/ Sales

Beginning inventory = 30,000

Purchases = 8,000

Ending inventory = 32,000

Food sales = 20,000 

Food cost percentage = (30,000 + 8,000 – 32,000) / 20,000 = 30%

The calculation for the ideal food cost percentage:

Ideal food cost percentage = (total cost per menu item)/(total sales per menu item)

Total cost per menu item = $5,000

Total sales per menu item = $20,000

Ideal food cost percentage = 5,000/20,000 = 25%

From the above examples, if we calculate the difference between ideal food cost percentage and actual food cost percentage, then it is 5%, which means that there is an extra 5% of food wastage or additional purchasing. Now that you have grasped these concepts, minimize them to maximise your profits!
