How to read your restaurant's daily P&L
Your profit and loss statement tells you whether last night actually made money. Most owners only see it monthly — but the best ones read a simple version every morning. Here's how.
A restaurant P&L shows your revenue minus your costs to reveal profit. The three numbers that matter most are food cost %, labor cost %, and their sum — your prime cost, which should land around 55-65% of revenue. If prime cost is healthy, the restaurant usually is.
The lines that actually matter
A full P&L has dozens of lines, but day to day you only need to watch a handful:
Prime cost is the number to watch
Prime cost — food plus labor — is the clearest single signal of a restaurant's health because it's the part you control. Add the two together:
If your prime cost is 60%, you have 40 cents of every dollar left to cover rent, utilities, insurance, and profit. If it climbs to 72%, that cushion is almost gone — and that's how a busy restaurant still loses money.
Why read it daily, not monthly
A monthly P&L tells you what already happened — too late to change it. A daily read lets you catch a bad pattern on day two instead of day thirty. If last night's labor ran hot, you can adjust tonight's schedule. That's the difference between reacting and steering.

Prime cost is your food cost plus your labor cost, combined, as a percentage of revenue. It's the single most important number on a restaurant P&L because it's the part you control most directly. A healthy prime cost is 55-65% of revenue; above 70% makes profitability very difficult.
At minimum: revenue (sales), food cost percentage, labor cost percentage, and prime cost (the two combined). A full monthly P&L adds rent, utilities, insurance, and other fixed costs, but for daily decisions those four lines tell you most of what you need.
A monthly P&L only tells you what already happened, when it's too late to fix. Reading a simple daily P&L lets you catch problems immediately — if labor ran high last night, you can adjust tonight's schedule. Daily visibility is the difference between steering the business and just reporting on it.
Most restaurants run a net profit margin of 3-9%, with full-service typically on the lower end and quick-service higher. Margins are thin, which is exactly why controlling prime cost (food plus labor) matters so much — small improvements there flow straight to the bottom line.
