How to read a restaurant P&L

A restaurant P&L in standard format answers questions a generic income statement can't. Most operators are handed the generic one.

A guide from Where the money actually goes

If your bookkeeper hands you a statement with revenue at the top, a wall of expenses in alphabetical order, and net income at the bottom, you have a generic small-business P&L. It's not wrong, but it can't answer the two questions that matter most in this industry: what is my prime cost, and what did management actually control this period.

The National Restaurant Association publishes a standard chart of accounts for exactly this reason — the Uniform System of Accounts for Restaurants. Its value isn't the account list. It's the order.

The structure

Two subtotals do the work. Prime cost collects the costs that move weekly. Controllable income separates what a manager influenced from what a lease signed three years ago determined. If controllable income is strong and operating income is weak, nobody in the building is doing anything wrong — you have a rent problem.

Percentages against the right base

The detail that trips people up: food cost is expressed as a percentage of food sales, and beverage cost as a percentage of beverage sales. Everything below the prime cost line is expressed against total sales.

Run food cost against total sales and it drops as your bar does better, which makes a beverage-led quarter look like the kitchen improved. It didn't. This single error has convinced more than one operator that a cost problem fixed itself.

The line almost everyone misplaces

Utilities are a controllable operating expense. They are not occupancy.

Occupancy means rent, common area maintenance, property and real estate taxes, and insurance on the building. The published benchmarks — roughly 5–7% of sales for a good lease, 7–9% typical, and over 9% where it starts to seriously impair profitability — are all calculated with utilities excluded.

Fold your $40,000 power bill into occupancy and a healthy 7% ratio reads as a worrying 9.5%. Operators have renegotiated leases they didn't need to renegotiate over this. Utilities run roughly 3–5% of sales and belong on their own line, where you can actually act on them.

Two more conventions worth knowing

Non-alcoholic beverages generally go in food. Standard practice records soda, coffee and juice sales and costs in the food accounts, not beverage. Beverage means alcohol. Mixing NA drinks into the beverage line inflates your pour cost and sends you looking for a bar problem that doesn't exist.

Paper is treated differently by format. In limited-service restaurants, paper and packaging is a separate line within cost of sales, historically running 3–4% of sales. In full-service it sits in direct operating expenses. If you've built a large to-go business inside a full-service restaurant, that line has grown and probably never got repriced into the menu.

Reading it in order

Start at prime cost, not at the top. It's one number and it tells you whether the last period was operationally sound.

Then look at cost of sales and labor separately, each against its own base, to see which half moved.

Then controllable income, which is the fairest measure of your management team.

Then occupancy, which you can't fix this month but which determines whether any of the above is enough.

Then operating income. Note what this figure does and doesn't include: it's before depreciation, interest and owner distributions. Published net margins of 3–8% for full service and 4–10% for fast casual are measured after those items, which is why your operating income line will look healthier than the margin statistics you read about — and why comparing the two directly will mislead you.

Discounts, comps and what counts as a sale

A surprising amount of confusion lives at the very top of the statement. Gross sales, net sales and the number your POS shows on the daily summary are frequently three different figures, and benchmarks are calculated against net sales — gross sales less discounts, comps and voids.

Compare your food cost against gross sales and it looks better than it is, because you're dividing real cost by revenue you never collected. A restaurant comping 3% of sales and measuring against gross is understating food cost by roughly a point, permanently.

Comps also deserve to be visible rather than netted away silently. A comp is a marketing decision, a service-recovery decision, or a control problem, and you can't tell which if the number never appears. Track manager comps, service recovery and staff meals separately even when they roll up to one line.

What each line should look like

Rough published targets for a full-service independent, as a percentage of total sales except where noted:

Two cautions. These are targets rather than descriptions — full-service labor runs a median around 36.5% of sales, while operators who are actually profitable run closer to 34.2%, so the target and the reality are several points apart across the industry. And hitting every one of these simultaneously would produce an operating income near 19%, which almost nobody achieves. Use them as a ranking device to find your worst line, not as a scorecard.

How often to produce it

Monthly for the full statement, weekly for prime cost. The full P&L depends on accruals and closings that can't realistically happen every week; prime cost only needs sales, purchases, an inventory count and payroll.

Consider thirteen four-week periods rather than twelve calendar months. Every period then holds the same number of weekend days, which removes the single largest source of noise in period-over-period comparison. A five-weekend month looks like growth and isn't.

The reason this matters right now

Only 42% of US restaurants were profitable in 2024. The half that weren't did not lack effort. Many of them lacked a statement formatted to show where the money was going while there was still time to act.
