What is a Healthy Prime Cost for Restaurants?
Prime cost is the single most important number in your restaurant. It’s also a number that has drastically changed over the past number of years. What was once realistic is no longer realistic. Everything costs more now.
Before we talk about what’s realistic today, let’s make sure we’re talking about the same thing.
What Prime Cost Actually Is
Prime cost is the combined total of your food cost, beverage cost, and labor cost, expressed as a percentage of sales.
The formula is: (Food Cost + Labor Cost) / Total Sales = Prime Cost %
If your food cost last month was $34,000, your labor was $26,000, and your sales were $100,000 — your prime cost is 60%.
That number tells you more about the health of your restaurant than almost anything else on your P&L.
What Healthy Looks Like by Concept Type
There is no single universal target. Prime cost benchmarks vary based on your concept, service model, and cost structure. We operate in the QSR and fast casual worlds, where general targets are:
QSR and Fast Casual
Food cost target: 28% to 34%
Labor cost target: 25% to 32%
Prime cost target: under 60%
However, no matter what sector you operate in (QSR, fine dining, full service, etc.), we recommend keeping your prime costs around 60%. Above 65% should signal that something needs attention. Prime cost above 70% is a crisis, even if sales look strong.
Why Operators Struggle to Know Their Number
Here's the problem many restaurant owners run into: they find out their prime cost at the end of the month, when the books are closed and the damage is done.
By the time you see a problem, you've already lost three or four weeks of margin.
Prime cost needs to be tracked weekly. Not because it's a nice habit but because it's the only way to catch a problem while you still have time to act on it.
A 2% spike in food cost that shows up on a weekly report is a conversation. A 2% spike that shows up on a monthly P&L is a loss you can't recover.
What to Do If Your Number Is High
If your prime cost is running above your target, the answer is almost never "sell more." Higher sales with undisciplined prime cost just scales the problem. Although we sometimes say that sales cover a multiple of sins, those things are still “sins.”
Start here:
Identify which side is driving it: food or labor
On the food side: check your theoretical vs. actual variance, review your inventory counts, and look at portioning and waste
On the labor side: review your scheduling against your sales forecast, check for overtime, and look at labor by daypart
We set up automated overtime reports that get emailed to our management team in order to curb overtime before it gets unhinged
Set a weekly review cadence and assign an owner to the number
One percentage point of prime cost improvement on $1.5M in annual sales is $15,000 back in your pocket. Three points is $45,000. In the our world of slim margins, that can be game changing money.
