How to Read a Restaurant P&L
A restaurant P&L built on a generic chart of accounts will balance. It just won't tell you anything useful. The business needs numbers organized the way a restaurant actually runs, not the way a template assumes every business runs.
Why generic bookkeeping falls short
A standard small business P&L lumps cost of goods sold into one line and calls it done. A restaurant needs food cost separated from beverage, labor split by role and department, and enough category detail to see which part of the operation is actually driving a number up or down. Without that, "food cost is high" is the only insight available, and it's not one anyone can act on.
What belongs on a real restaurant P&L
- Sales, by category. Food, beverage, retail, and catering kept separate.
- Cost of goods sold, by category. Tied to actual usage, not just purchases.
- Labor, by department. Front of house, back of house, and management, split out.
- Prime cost. Food and beverage plus labor, rolled into one combined number.
- Controllable expenses. Supplies, repairs, marketing, credit card fees.
- Occupancy and fixed costs. Rent, insurance, utilities.
- Other income and expenses. Kept separate from operations, not blended in.
The one number to watch first: prime cost
Prime cost is food and beverage cost plus labor cost, divided by revenue. It's the single number most full-service restaurants live or die by, because it rolls up the two costs an operator can actually influence week to week.
| Prime cost | What it usually means |
|---|---|
| Below 55% | Often understaffing, not efficiency |
| 55-65% | Where most full-service restaurants land |
| Above 65% | A structural problem, not a menu problem |
If prime cost is climbing and nobody can say exactly why, that's usually the books, not the business. Clean, category-specific bookkeeping is what turns "something's off" into "here's what's off, and here's what to do about it."
The bank account and the P&L can both be accurate and still tell two different stories. Clean books are what make them agree.
Frequently asked questions
What is prime cost and why does it matter more than food cost alone?
Prime cost combines food, beverage, and labor cost into one number against revenue. It matters more than food cost alone because a restaurant can hit its food cost target and still be unprofitable if labor is out of line, or vice versa. Prime cost catches both at once.
What percentage of sales should labor be?
It depends on service style. Quick service typically runs 25 to 30 percent, fast casual 26 to 32 percent, casual and family dining 28 to 35 percent, and full-service sit-down concepts often land between 30 and 37 percent.
How is a restaurant P&L different from a standard small business P&L?
A standard P&L groups cost of goods sold into a single line. A restaurant P&L needs that broken into food and beverage separately, labor split by department, and enough category detail in the chart of accounts to trace a cost problem back to where it's actually coming from.
