How to Read a Restaurant P&L: The Numbers Your Accountant Should Be Explaining
A scene we've watched play out a few hundred times: month-end financials land in an inbox. The operator opens the P&L (cue ominous music), scrolls straight to the bottom line… has a feeling about it (directors note: relief, confusion, dread, angst, avoidance, whatever). Then closes the file.
End scene or “fin” for you cineastes.
Total time spent: about eleven seconds, more akin to checking the weather than actually reading a P&L.
A restaurant profit and loss statement is the most useful management document you own, but most operators have never been walked through one properly. Not because they can't handle it, but because nobody ever sat down and explained what each line is actually telling them.
If your accountant hands you a P&L and disappears until next month, you're getting a report card with no teacher. Or worse, a treasure map but someone has already gotten the treasure chest.
So let's go line by line.
First: A Restaurant P&L Doesn't Look Like Anyone Else's
Before the specifics, understand why a generic P&L fails you. There’s no such thing as a standard small-business income statement. A generalist approach is to lump costs into big buckets like "cost of goods sold," "payroll," "operating expenses,” and call it a day. What works for a law firm doesn’t work for a construction contractor.
And it fails for a restaurant where your two largest costs move every single week, are partially within your control, and interact with each other. A properly built restaurant P&L is organized so you can see which costs you can act on, how fast you can act on them, and what happens when you do.
Everything below assumes your books are structured that way. If they aren't, that's the first conversation to have. (We've written about why that structural difference matters - a chart of accounts designed for a dentist's office with "restaurant" written on top is not restaurant accounting).
And a super important thing to raise: your financial record is the history of what happened for forward looking planning and analysis. It SHOULD NOT be the primary cost management tool you are relying on to manage your business. A lot of our work at Harmony is interfacing with management teams to manage costs on a weekly basis so you can proactively create the P&L you want.
Sales: More Than One Number
The top line should never be a single figure. You want net sales (gross sales minus discounts, voids, and promotions) because that's the money that actually arrived. And you want it broken out by revenue stream: dine-in, bar, takeout, third-party delivery, catering, private events, retail. Each one carries a completely different cost profile. A restaurant doing 20% of its volume through delivery apps is running a different business than one doing 20% through the bar, even at identical gross sales. Your sales breakdown guides your cost structure.
What your accountant should be explaining: which channels are growing, which are diluting your margin, and how much of your "sales growth" is actually price increases versus real traffic.
Cost of Goods Sold: Food and Beverage, Never Combined
Food cost and beverage cost belong on separate lines, and beverage should ideally be split further, as liquor, beer, wine, and non-alcoholic all behave differently. Blending them hides problems. A tightening food cost can mask a bleeding bar program for months.
Commonly cited ranges land food cost somewhere around 25–30% of food sales, liquor in the mid teens to low twenties, beer around 20–25%, and wine anywhere from the high twenties up. Treat those as orientation rather than gospel - a steakhouse and a pizzeria have no business chasing the same number.
The bigger issue is inventory timing. If you're not counting inventory consistently, your COGS isn't a cost, it's a purchase number wearing a costume. Purchases in a month with a big produce order look like a crisis; the following month looks like a triumph. Neither is real. You can manage your business without taking inventory but you will have to look at quarterly pricing data or longer to get a sense of food cost.
Consistent counts and proper adjustments are what turn COGS into a number you can make decisions with, and tools like MarginEdge can let you compare theoretical food cost against actual food so you can see the gap between what your recipes should have cost and what you actually spent.
What your accountant should be explaining: the size of that theoretical-vs-actual gap, and whether it points to waste, theft, portioning drift, or vendor price creep.
Labor: Fully Loaded, Broken Out
Labor should never appear as one line either.
You want front of house separated from back of house, hourly separated from salaried management, and the fully loaded number. Wages alone understate your real labor cost by a meaningful margin once you add payroll taxes, workers' comp, benefits, and employer-side burden. Plenty of operators have built a staffing model on a labor percentage that quietly excludes 15% of what labor actually costs them.
What your accountant should be explaining: labor as a percentage of sales by daypart, where overtime is concentrated, and whether your management salaries are appropriately sized to your volume.
Prime Cost: The One Number to Memorize
Cost of Goods plus fully loaded labor equals prime cost. If you only track one metric, track this one - it captures the overwhelming majority of the costs you can actually influence.
For most full-service concepts, the conventional target is at or below 65% of net sales, with well-run operations pushing toward the high-fifties. Quick service and fast casual generally run lower.
If prime cost is drifting up two or three points across a quarter, you have a problem that no amount of marketing spend will fix - and you want to catch that in week three, not in April when the tax return arrives. It’s such a powerful metric that we can reliably guess that a restaurant with a larger than 65% prime cost will not have meaningful profits.
Controllable Expenses: Where the Quiet Leaks Live
Aside from our Prime Cost categories we have five other “controllable” categories: Direct Operating Expenses, Marketing, Promotions / Discounts, and General & Administrative expenses. Collectively, they're often 12–18% of sales, and they're where cost creep hides best - a 40-basis-point processing rate increase or a stack of forgotten subscriptions doesn't announce itself (we went deeper on this in our piece on hidden restaurant costs).
The degree to which these costs are manageable varies, General & Administrative costs tend to be stickier but all should be monitored for improvement, overspending and deviations from KPIs or budgets.
What your accountant should be explaining: which of these lines is trending up faster than sales, KPI / Budget deviations, large one time charges and which ones are actually negotiable.
Occupancy: Fixed, Which Is Exactly the Danger
Rent, CAM, property taxes, insurance. You can't flex these next Tuesday, which is precisely why they need watching as a percentage of sales. A rent figure that was comfortable at $3.2M in volume becomes a serious constraint at $2.6M - the dollar amount never changed, but your ability to carry it did. Most healthy operations keep total occupancy in the 6–10% range.
Most landlords aren’t dumb, they are just rapacious rent seekers who seek to make money on people who actually work for a living (we kid, we kid). In all seriousness, we’ve had many clients who say the rent was the problem with 70% Prime Cost numbers and it’s hard to make a credible case to a landlord that you need rent relief when your controllable expenses show a story of achievable margin improvements.
The Bottom of the Statement: Know Which "Profit" You're Looking At
There are usually three different profit numbers on a restaurant P&L, and confusing them is a common and expensive mistake.
Net Operating Income / Restaurant-level profit (sometimes called store-level EBITDA) is what the four walls produced before corporate overhead, debt service, and owner compensation. This is the number that tells you whether the operation works.
EBITDA is the number lenders, landlords, and buyers care about most.
Net income sits below depreciation, amortization, interest, and one-time items — and it's the number that drives your tax bill, but it's the worst single indicator of operational health, because a fully depreciated kitchen and a brand-new build-out look wildly different on that line while running identically well.
Two Rules That Change How You Read Everything Above
Percentages, not dollars. Dollar figures only tell you what happened. Percentages tell you whether it was good. A $4,000 increase in food cost is meaningless until you know what happened to sales.
One month is not data. A single period, viewed alone, is noise. You need it against the prior period, against the same period last year, and against a trailing three-month trend. You need to analyze trends, performance over a longer horizon. A data point isn’t a pattern so we often seek to look to perform variance analysis to uncover patterns and problems.
The Questions You Should Be Able to Answer
Run this list against your last set of financials:
What was my prime cost, and which direction is it moving?
What's my theoretical food cost versus actual, and what explains the gap?
What's my fully loaded labor percentage, and does it include taxes and benefits?
Which revenue channel is most profitable, and is my mix shifting?
Which controllable expense line is growing faster than sales?
What's my occupancy percentage, and what sales volume would make it uncomfortable?
Did I receive these financials within days of period close, or weeks?
If you can't answer most of those, the gap isn't your understanding. It's your reporting - and the person delivering it.
Financials Are a Conversation, Not a Delivery
We say this constantly around here: accounting should be a conversation. A P&L that shows up as an email attachment with no context is a compliance artifact. A P&L that shows up alongside someone who says "prime cost moved up 1.8 points, it's coming almost entirely from BOH overtime on Thursdays and Sundays, and here's what we'd look at first" is a management tool.
That's the difference Harmony is built to deliver: accurate, on-time financials from a 100% American in-sourced team that knows this industry cold, paired with advisory guidance that turns the numbers into decisions. And if you'd like your managers reading these statements as fluently as you do, our Hospitality Academy Restaurant 101 course covers exactly this ground.
If your monthly financials feel more like a puzzle than a roadmap, let's talk. A short conversation with our team will tell you what your P&L is actually saying - and what it should be telling you every single period.
