Where Your Food Cost Is Leaking (And How to Stop It)

Food cost is the number one profit killer in hospitality. Not labour, not rent, not utilities. Food cost. And the frustrating part is that most venues have no real idea what their actual food cost is until the damage is already done.

If you are running a cafe or restaurant and your margins feel tighter than they should be, this is where to start looking.

What is food cost and why does it matter

Food cost percentage is the cost of your ingredients as a percentage of the revenue those dishes generate. If a dish sells for $20 and the ingredients cost $6, your food cost on that dish is 30 percent.

For most cafes and casual dining venues, you want to sit between 28 and 32 percent overall. Fine dining can be higher. Fast casual should be lower. If you do not know your number right now, that is the first problem to fix.

The five places food cost leaks

In most venues, the money is not disappearing in one obvious place. It is leaking across five or six small points that add up to a serious problem.

Portion sizes are the most common issue. When there is no standard, chefs plate by feel and portions vary from shift to shift. One generous pour of protein across 80 covers a day adds up to thousands of dollars a month.

Over-ordering and waste is the second one. If you are ordering based on habit rather than actual covers, you are regularly throwing money in the bin. Every item that hits the bin has a purchase price, a labour cost attached to receiving it, and a disposal cost. It adds up fast.

Supplier pricing is another place people stop paying attention. Prices change regularly and many operators are not checking their invoices line by line. A $0.50 increase per kilo on chicken across a high-volume venue can cost thousands per year without anyone noticing.

Menu design is often overlooked as a cost lever. If your most popular dishes are also your lowest margin dishes, you have a design problem. The right menu engineering pushes customers toward high-margin items naturally.

Staff meals, wastage and theft round out the list. These are harder to talk about but real in every venue. Having a clear policy and accountability around these is not about distrust, it is about running a professional operation.

How to fix it

Start by costing every dish properly. Not a rough estimate — a real cost that accounts for every ingredient including oils, garnishes and sauces. Then check your actual food cost weekly against your theoretical food cost. The gap between those two numbers tells you where the money is going.

Standardise your portions. Write it down. Train your team on it. Check it regularly.

Review your supplier invoices monthly. Compare prices and do not be afraid to negotiate or switch suppliers for key items.
