The Difference Between Revenue, Profit, EBITDA & Cash Flow (Explained Simply)

The Difference Between Revenue, Profit, EBITDA & Cash Flow (Explained Simply)

By The Accounting Investor

If you’ve ever felt confused by terms like revenue, profit, EBITDA, and cash flow, you’re not alone. These numbers are often used interchangeably in investing conversations — but they measure very different things.

Understanding the differences is one of the fastest ways to become a better investor.
As a Chartered Accountant and long-time Singapore investor, here’s how I explain these terms in a simple, clear way — without accounting jargon.

By the end of this guide, you’ll be able to read company announcements with far more confidence.

1. Revenue — The Top Line (Not the Bottom Line)

Revenue is simply:

The total amount the company earned from selling goods or services.

It does not consider:

  • Costs
  • Expenses
  • Interest
  • Taxes

Revenue tells you how big the business is, but not how profitable it is.

✔ Good revenue signs:

  • Consistent growth
  • Better pricing power
  • Strong demand

✘ Red flags:

  • Revenue growing but profit shrinking
  • Revenue boosted by acquisitions instead of real growth
  • Revenue growing but cash flow falling (possible aggressive accounting)

Revenue is the start of the story, not the score of the game.

2. Profit — The Bottom Line (But Still Not Cash)

Profit tells you whether the company earned more than it spent.

But there are several types of profit:

  • Gross profit
  • Operating profit (EBIT)
  • Profit before tax
  • Net profit (after tax)

Each measures performance at a different stage.

✔ Gross Profit

Revenue minus the cost of producing goods/services.
Tells you whether the company has pricing power.

✔ Operating Profit (EBIT)

Gross profit minus all operating expenses.
Shows the true profitability of the business before interest and taxes.

✔ Net Profit

The final profit after interest, taxes, and one-off items.
This is the number most investors focus on — but it can be distorted by:

  • Fair value gains
  • Disposal profits
  • FX gains/losses
  • Government grants
  • Impairments

✘ Important warning:

Profit ≠ Cash Flow
A company can look profitable but be running out of cash.

3. EBITDA — A Popular but Misunderstood Metric

EBITDA stands for:

Earnings Before Interest, Tax, Depreciation & Amortisation

It is supposed to reflect the “core operating performance” of a business.

Think of it as:

Profit without the effects of capital structure, tax environment, and non-cash expenses.

Investors and analysts like EBITDA because it makes companies easier to compare.

But EBITDA can be misleading.

✔ What EBITDA is useful for:

  • Comparing companies with different capital structures
  • Understanding underlying operating performance
  • Valuing businesses (EV/EBITDA)
  • Assessing businesses with high depreciation

✘ What EBITDA hides:

  • Interest costs
  • Tax obligations
  • Maintenance CapEx
  • Working capital needs
  • Cash that must be spent to keep the business running

The truth:

EBITDA is not cash, not profit, and definitely not free cash flow.

It is only useful when paired with cash flow analysis.

4. Cash Flow — Where the Real Story Lives

Cash flow shows the movement of actual cash in and out of the business.

There are three main categories:

1. Operating Cash Flow (OCF)

Cash generated (or consumed) by core operations.
This is the most important number in the entire cash flow statement.

OCF explains whether profits are real.

2. Investing Cash Flow (ICF)

Cash spent on:

  • CapEx
  • Acquisitions
  • Investments
    Or cash received from selling assets.

3. Financing Cash Flow (FCF)

Cash from:

  • Borrowing
  • Share issuance
    Cash used for:
  • Debt repayment
  • Dividends
  • Share buybacks

✔ The number investors should care most about:

Free Cash Flow (FCF)

FCF = Operating Cash Flow − Capital Expenditure

Free Cash Flow is the money available for:

  • Dividends
  • Debt reduction
  • Reinvestment
  • Buybacks

Companies with strong FCF rarely fail.
Companies with weak FCF rarely sustain dividends.

5. Putting It All Together — Why These Differences Matter

Here is a simple summary most investors never learn:

✔ Revenue tells you size

✔ Profit tells you accounting performance

✔ EBITDA tells you operational performance (before key costs)

✔ Cash Flow tells you actual financial health

A company can have…

  • High revenue but low profit
  • High profit but low cash flow
  • High EBITDA but high debt
  • Strong accounting profit but weak cash generation
  • High dividends but insufficient free cash flow

This is why reading all three financial statements is crucial.

6. A Simple Real-World Example

Imagine a company reports:

  • Revenue: ↑ 12%
  • Net profit: ↑ 5%
  • EBITDA: ↑ 10%
  • Operating cash flow: ↓ 25%
  • Free cash flow: negative

On the surface, results look strong.
But the cash flow statement reveals:

  • Customers haven’t paid
  • Inventory piled up
  • Working capital deteriorated
  • Debt rose to support operations

This is not a healthy company.
Cash tells you what’s really happening.

7. The Investor’s Shortcut: My “Four Questions” Test

When I analyse a company, I ask:

1. Is revenue growing because demand is real?

Or because they extended easy credit?

2. Is profit supported by operating cash flow?

Or are there one-offs inflating earnings?

3. Is EBITDA hiding high maintenance CapEx or debt?

High EBITDA is meaningless if cash flow is weak.

4. Is free cash flow positive and stable?

If not, dividends may be at risk.

This simple test filters out most low-quality companies immediately.

Final Thoughts

Revenue, profit, EBITDA, and cash flow are all useful — but they mean different things.
To invest with confidence, you don’t need to memorise accounting standards.
You simply need to understand what each number represents, and how they fit together.

When you can interpret these metrics clearly, you’ll start seeing through:

  • Dividend traps
  • Weak business models
  • Aggressive accounting
  • Unsustainable growth stories
  • Companies masking weakness with non-cash profits

And you’ll become far better at spotting companies with:

  • Real demand
  • Sustainable profits
  • Healthy cash flow
  • Conservative management
  • Strong long-term potential

How to Evaluate Dividend Sustainability (Without Being Misled by Yield) — A Practical Guide for Singapore Investors A step-by-step, financial-statement-based method to judge whether dividends are truly sustainable — not just “high yield”. Published: 15 November 2025 | Category: Investor Education / Earnings Analysis Key Takeaways (If You Only Have 30 Seconds) Start with cash flow vs profit : dividends are paid with cash, not accounting earnings. Check Free Cash Flow (FCF) : if dividends > FCF for long periods, sustainability is at risk. Payout ratio is useful, but only when cross-checked against cash generation and business reality. Dividends from leveraged balance sheets are fragile — rising debt and refinancing risk often come first. One-off gains can inflate profit and “support” dividends temporarily — but do not last. Business model matters: cash-generative businesses usually sustain dividends better than cash-hungry ones. Use the 3-Circle Test : Cash F...
