3 Numbers Every Restaurant Owner Should Check Every Monday
You don’t need a finance degree or an hour of spreadsheet work to know whether your restaurant had a good week. You need three numbers, five minutes, and the discipline to actually look at them before the week gets away from you.
Here’s the framework I give every operator I work with.
Prime Cost
Your combined food cost and labor cost, as a percentage of revenue. This is the single number that tells you more about your restaurant’s health than anything else on the P&L.
Theoretical vs. Actual Food Cost
Theoretical food cost is what your menu pricing and recipes say your food cost should be. Actual food cost is what you actually spent. The gap between the two is where waste, over-portioning, theft, and inventory shrinkage live — and it’s usually bigger than owners expect.
Labor Cost by Daypart
Not just your weekly labor percentage — labor cost broken out by shift or daypart. A restaurant can hit its weekly labor target on paper while badly overstaffing slow Tuesday lunches and understaffing a busy Saturday dinner. The weekly average hides both problems.
What’s the first number you look at on a Monday?
Why these three, and not a longer list
There are dozens of numbers you could track. These three matter most because they’re leading indicators, not lagging ones — by the time your monthly P&L tells you margins slipped, the week that caused it is long gone. Checking prime cost, the theoretical-vs-actual gap, and labor by daypart every Monday means you catch drift in days, not months.
What to do when a number is off
Don’t panic over a single bad week — look for a pattern across two or three weeks before reacting. A one-off spike in food cost might be a delivery timing issue. A prime cost that’s crept up for a month straight is a structural problem that needs a real diagnostic, not a quick fix.
That’s usually the point where a forensic outside read pays for itself — not because you can’t see the number, but because you need someone to trace exactly where in the operation it’s coming from.
Know your numbers, but not sure what’s driving them?
A Diagnostic Audit traces prime cost drift back to its actual source — vendor, labor schedule, portioning, or menu pricing.
