In a recent LinkedIn post, Cruz Gamboa highlights a critical financial metric that many founders overlook, even those with seemingly healthy profit margins. Gamboa shares an anecdote about a founder experiencing significant cash flow issues despite a strong margin, illustrating a common pitfall in business management.

Gamboa begins by setting the stage for this common dilemma:

A 70% margin and an empty bank account can be the same business.

The post details a conversation with a founder who, despite having a margin superior to some highly profitable companies, found herself consistently operating at a loss. This situation led Gamboa and the founder to analyze her finances directly.

Uncovering the Hidden Financial Drain

According to Cruz Gamboa, the root of the problem wasn’t the profit margin itself, which the founder believed to be strong. Instead, the issue lay elsewhere, in a single, often-ignored number. Gamboa explains the core issue:

We opened a blank spreadsheet, and the reason showed up fast. It wasn’t the margin. The margin was never the problem.

This emphasizes that a high margin, while desirable, does not automatically translate to financial stability or profitability if other key financial aspects are not managed correctly. Gamboa suggests that this overlooked number is the deciding factor in whether a business retains its earnings or sees them evaporate.

The Decisive Metric for Founders

Cruz Gamboa asserts that there is one specific number that dictates whether a business keeps its money, a metric that many founders have never even calculated. This number, he explains, acts as a threshold.

There’s one number that decides whether you keep your money, and most founders have never run it. Below it, a world-class margin bleeds every month. Above it, the same margin prints.

In Gamboa’s view, understanding and monitoring this specific metric is paramount for sustainable business growth. He posits that by identifying and managing this number, founders can transform a seemingly profitable business with cash flow problems into one that consistently retains its earnings.

Actionable Insights for Business Leaders

Gamboa promises to reveal this crucial number and guide readers on how to calculate it in the full context of his original post (which this article is covering). The implication is that this metric offers a more direct path to understanding and improving a company’s financial health than focusing solely on profit margins. As Cruz Gamboa notes, focusing on the right number can make the difference between a business that struggles to stay afloat and one that thrives.

This insight from Cruz Gamboa serves as a vital reminder for founders and CEOs to look beyond the surface-level profitability metrics and delve into the operational financial details that truly drive cash flow and long-term success.
