How We Think About Restaurant Financials (A CFO Perspective)

I've spent the better part of 15 years inside restaurant financials — not just looking at them from the outside, but building the systems, doing the closes, sitting across from operators and explaining what the numbers actually mean for their business. What I've learned is that most restaurants don't fail because of bad food or bad service. They fail because of financial decisions made with incomplete visibility, usually over a period of months or years before the crisis becomes unavoidable.

Here's how I actually think about restaurant financials — the framework I apply when I start working with a new operator, and the mental models that consistently separate the restaurants that build real wealth from the ones that work extremely hard for very little.

The Three Numbers That Tell You Almost Everything

There are dozens of metrics in a restaurant P&L. But when I'm evaluating the health of a restaurant for the first time, three numbers tell me most of what I need to know:

• Food cost percentage — what percentage of food revenue is consumed by the cost of food sold. Target: 28–34% depending on concept.
• Labor cost percentage — total labor (including taxes and benefits) as a percentage of total revenue. Target: 28–35% depending on service model.
• Prime cost percentage — food cost plus labor cost combined. This is the single most important operational metric in a restaurant. A well-run restaurant should keep prime cost below 60–65% of revenue.

These three numbers immediately tell me whether the restaurant has a structural profitability problem or an operational execution problem — and those require completely different responses. If prime cost is 72%, no amount of revenue growth fixes the business. If prime cost is 58% but the restaurant is losing money, the answer is somewhere in overhead or volume.

Revenue Is Vanity, Cash Flow Is Sanity

I've worked with restaurants doing $3M in annual revenue that were genuinely struggling, and restaurants doing $900K that were building real wealth. Revenue is the starting point, not the destination. What matters is what the business actually generates in distributable cash after all real costs — including the owner's reasonable market-rate compensation.

The most common distortion I see: an owner who works 60 hours a week in the restaurant, pays themselves very little (or nothing), and points to strong net income as evidence of profitability. Strip out the owner's labor at a market rate, and the profitability often vanishes. That's not a profitable business — it's a job with overhead. I always calculate what I call the "true economic margin" — profitability after imputing a market-rate owner salary. That's the number that determines whether the business is viable as a scalable enterprise or whether it only works because of the owner's personal sacrifice.

The Delivery Channel Problem Nobody Talks About

Third-party delivery has become a meaningful revenue stream for most restaurants. It's also, for many of them, an inadvertent profitability destroyer. Here's why: delivery orders carry a 20–30% commission to the platform, often have different (usually higher) food costs due to packaging requirements, and frequently involve the same labor cost per order as a dine-in table — without the beverage attachment, the upsell, or the tip that benefits the business in other ways.

When I build a restaurant's P&L correctly, I separate revenue by channel — dine-in, takeout, delivery, catering — and calculate contribution margin by channel. The results are often surprising. In more than a few cases, I've shown an operator that their delivery channel is generating revenue but negative contribution margin — meaning they'd be better off without it. In other cases, delivery is strong but they're leaving money on the table by not negotiating platform rates or testing menu pricing that accounts for commission.

"The restaurants that thrive long-term aren't the ones with the highest revenue. They're the ones where the owner genuinely understands the economics of every channel, every menu category, and every labor hour — and makes decisions accordingly."

Why I Focus on Weekly Reporting, Not Monthly

Most restaurants review financials monthly. By the time you see the July P&L in mid-August, you've lost 45 days of opportunity to correct a food cost problem, a labor scheduling issue, or a delivery commission that's quietly running away. In a business with 10–15% net margins, a 2-point food cost increase sustained for 45 days before it's caught can cost $8,000–$15,000 in margin depending on volume. Monthly reporting is compliance. Weekly reporting is management.

The framework I implement with restaurant clients includes a weekly flash report — a one-page summary of the week's revenue, food cost, labor cost, and prime cost percentage, compared to the prior week and the same week last year. It takes about 20 minutes to produce and answers the question: "Is this week's performance in line with expectations, and if not, where specifically is the variance?" That's the question that matters, and it needs to be asked every week — not every month.

The Exit Question Most Operators Never Ask

Most restaurant operators think about their business in terms of annual income. Very few think about it as an asset with a potential sale value — and that's a significant opportunity cost. A restaurant with $300,000 in normalized EBITDA can sell for $900,000–$1.5M at a 3–5x multiple, depending on concept, location, lease terms, and how cleanly the financials are presented. That same restaurant with messy books, no documented systems, and owner-dependent operations might sell for $400,000 — or not sell at all.

Building toward a potential exit doesn't mean you're planning to sell. It means you're running the business in a way that builds enterprise value — documented systems, clean financials, normalized EBITDA, reduced owner-dependency. Those same attributes that increase sale value also make the business more enjoyable and less stressful to operate. The discipline of thinking like an owner and an investor simultaneously is what separates the restaurants that build wealth from the ones that generate income.
