The battle for financial reporting supremacy between cash flow and earnings is ongoing, with ardent proponents on both sides. Those who put more weight on earnings argue that accrual basis net income is the best representation of a company’s performance in a given period. Meanwhile, those who scorn earnings and prize cash flows maintain that earnings are useless unless they can be converted into cash.

Who’s right?

The frustrating (and probably predictable!) answer is that both metrics are necessary to analyze the performance of a business—neither is sufficient by itself. Here are the benefits that each offers.


1. Cash Flows

Cash flow represents the actual money moving in and out of a business. It’s the lifeblood of any company, and without it, even profitable businesses can go bankrupt. Here’s why it matters:

💰 Liquidity & Solvency: A company with strong cash flow can pay its employees, suppliers, and debts on time—regardless of its reported earnings.

📈 Business Sustainability: Startups and fast-growing businesses often burn through cash quickly. Watching cash flow ensures they don’t run out of money before reaching profitability.

📉 Avoiding the “Profitable but Broke” Trap: A business might show strong earnings but have all its cash tied up in accounts receivable or inventory, leading to financial distress.

💪 Ability to Invest & Grow: A company with solid free cash flow (FCF) can reinvest in expansion, new products, or acquisitions without relying on external financing.

👑 Cash Is King in Recessions: During economic downturns, businesses with strong cash reserves have a competitive advantage, while those with weak cash flow struggle to survive.


2. Earnings

Earnings (also called net income or profit) show how much money a company makes after accounting for all revenues, expenses, taxes, and interest. It’s the classic bottom-line number that Wall Street analysts, investors, and executives track. Here’s why it’s valuable:

🚀 Long-Term Performance Indicator: Earnings provide insight into the business’s ability to generate profit over time, not just in the short term.

🔎 Accrual Accounting Gives a Full Picture: Since earnings reflect revenue that has been earned (even if not yet collected as cash), it shows the company’s overall profitability better than cash flow alone.

🏛️ Investor & Market Perception: Public companies are valued based on their earnings multiples (P/E ratios), so strong earnings often drive stock prices higher.

🥇 Better for Comparing Companies: Earnings allow investors to compare businesses in the same industry on an apples-to-apples basis, as cash flow can be volatile based on working capital swings.

✅ Tax & Debt Management: Many businesses focus on optimizing earnings since taxes and debt covenants are often tied to reported profits.


The need to study both a business’s cash flows and its earnings is emblematic of a larger trend in financial reporting—no information should be consumed in a vacuum. To truly understand a company, you need to examine every individual line item on its financial statements and see how the puzzle pieces fit together.
