Restaurant Bottom Line

Protecting the bottom line. The operator-CFO perspective on restaurant P&L.

The 4-Wall Series

TL;DR

  • 4-wall EBITDA = store-level EBITDA before corporate G&A and above-store allocations. It’s what the four walls generate on their own. It is the number that tells you if a location is actually working.
  • The flagship article defines the number. The calculator lets you run yours. The companion pieces cover the difference vs consolidated EBITDA, how to calculate it, and where margins land by concept.
  • The valuation article ties it all together: buyers pay multiples of 4-wall EBITDA, and understanding this stack is what changes what your business is worth.

The 4-Wall Series is the deep-dive track on unit economics for people who make decisions about restaurants, not the ones who post about them.

Every article in this series is built around one number: 4-wall EBITDA. It is the number a restaurant produces before corporate overhead is layered on. It is what tells you whether a location is actually working. It is what buyers pay multiples of. It is what operators optimize when they know what they are doing.

If you are evaluating a location, running a portfolio, underwriting a deal, or trying to figure out whether your concept scales, you already own the data. The question is whether you know how to read it.

You already own this if you understand these numbers. This is the series that teaches you how.

FAQ

What is 4-wall EBITDA?

The profit a single location produces before any corporate overhead is layered on. Revenue minus COGS, labor, occupancy, and other in-store operating costs. It is the number that tells you whether the four walls of that location are actually earning money.

Who is the 4-Wall Series for?

Restaurant operators evaluating a location, multi-unit owners running a portfolio, buyers underwriting a deal, and investors sizing a concept. If a P&L crosses your desk, the series is for you.

Where should I start?

Start with the flagship article, then run your own P&L through the calculator. After that the companion pieces on how to calculate it, how it differs from consolidated EBITDA, and where margins land by concept will each land differently because you have your own numbers on the screen.

Why does 4-wall EBITDA matter for restaurant valuation?

Because buyers pay multiples of it. Consolidated EBITDA gets discounted for overhead they can strip out. 4-wall EBITDA is closer to the true earning power of the assets they are actually buying. Understand this stack and you understand what your business is worth.
