Are You Reading Your P&L Backwards?

Do you have strong P&L reading skills?

A restaurant P&L can feel intimidating. Rows of numbers, accounting codes, percentages, variances, and a few red figures that make everyone in the room go quiet.

I've sat in that room more times than I can count, on both sides of the table. And here's what twenty years of running restaurants taught me: a P&L isn't really an accounting document. It's the financial story of everything that happened inside your restaurant. Every plate served, every shift scheduled, every product wasted, every guest who came back and every one who didn't. When the story ends in a healthy profit, cha-ching. When it

ends in a battlefield of red numbers, it's time to investigate.

The Simple Math, and the Not-So-Simple Part

The formula is basic: Sales − Cost of Goods Sold − Operating Expenses = Profit Sales = total revenue generate

COGS = cost of food, beverages, packaging, and other product costs

Operating Expenses = labor, rent, utilities, marketing, repairs, technology, and everything else required to keep the doors open

What's left after subtracting both from sales is your profit. Simple enough. The hard part is what happens before that number ever appears, how every transaction gets categorized on the way in.

That starts wit

h your chart of accounts, the filing system behind the P&L.

Lump every expense into one broad "restaurant expenses" bucket and bookkeeping gets easier while actual analysis becomes impossible. The goal isn't more accounting complexity. It's enough detail to spot a problem without drowning in a hundred accounts nobody manages.

How Often to Actually Look

A full P&L should come together every four weeks or monthly, not once a quarter.

By the time a quarterly report shows a food-cost problem, the damage is already done.

The right rhythm has three layers. Daily: sales, average check, labor, comps The stuff that tells you what's happening right now. Weekly: sales versus budget, labor percentage, preliminary food cost The stuff that tells you whether a pattern is forming. Monthly: the full picture, revenue through profit, the stuff that tells you how the business actually performed.

What to Actually Look For

Don't start at net profit. Work down from the top.

Sales tell you whether the concept, pricing, and guest experience are actually working together, not just how much money came in the door. If food or beverage cost climbs, don't assume automatically the chef is over-portioning. It could be vendor pricing, waste, a menu that no longer reflects real product cost, or a dozen other things. The number raises the question. It never answers it by itself.

Labor needs to be read in both dollars and percentage, because a rising labor line doesn't automatically mean overstaffing. Sometimes it just means sales came in soft and the percentage moved on its own.

The goal was never less labor. It's productive labor.

Then there's prime cost, labor and cost of goods combined, which I'd argue is the single most important number on the whole page, since it's your two biggest controllable costs living together. A restaurant can post strong sales and still struggle if food and labor aren't managed as one problem instead of two.

Operating expenses deserve a second look whenever they're climbing, duplicated, or quietly not earning their keep anymore. And profit, the bottom line, is where you ask what actually drove it. Stronger traffic? Smarter pricing? Disciplined labor? Or just a temporary dip in expenses that isn't going to repeat next month?

Red numbers were never the enemy.

Unexplained red numbers are.

Benchmarks Are Clues, Not Commandments

Everyone wants to know the "right" food cost or labor percentage.

There isn't one. A quick-service concept and a fine-dining room shouldn't be measured by the same yardstick, and neither should a bakery and a steakhouse.

The Better Questions Does performance match the business model?

Are we hitting budget?

Can we explain the variances?

Are we protecting quality while we chase profitability?

Make the Numbers Do Something

A P&L only matters if someone acts on it. Food cost up two points means the chef reviews portioning by Friday. Labor over budget means the GM adjusts deployment before the next schedule posts. That's the difference between a report that sits in an inbox and a tool that actually runs the restaurant.

Sales bring the money through the door.

Operational discipline is what protects it once it's there.

Want a second set of eyes on what your own P&L is actually trying to tell you?

That's exactly the conversation worth having.
