Earnings Before Interest, Taxes, Depreciation, and Amortization

What it measures

EBITDA is the difference between what you make (gross margin: revenue minus product-delivery costs) and what you spend to run the business (operating, overhead, and G&A expenses). It excludes interest on debt, income taxes, depreciation of fixed assets, and amortization of intangibles — real costs, but not part of day-to-day operating profit. In Plantactic, EBITDA starts from gross margin (not net revenue) and subtracts total operating-and-overhead opex (Tech, R&D, Ops, G&A, Sales & Marketing), proxying operating profit for a SaaS P&L without a separate D&A line.

Why it matters

You watch EBITDA because it shows whether your core business is profitable before financing, tax, and accounting effects muddy the picture. Investors and boards use it to ask one question: can this business fund itself from operations, or is it burning cash faster than revenue grows? Because EBITDA strips out capital structure, tax situation, and depreciation method, it lets you compare operational efficiency across companies on a level playing field. For SaaS it sits close to operating cash flow before working-capital swings, so a rising EBITDA usually signals the path to sustainability.

How to read it

Positive EBITDA means gross profit covers all operating costs — you're profitable at the operating level. Negative EBITDA means you're spending more to operate than you earn on products, so you need external funding or revenue growth to turn the corner. Read EBITDA as a trend, not a snapshot, and track EBITDA margin (EBITDA ÷ Total Revenue) to normalize for size — two companies can both post the same EBITDA dollars while one is far healthier on a margin basis. Compare the EBITDA trend to revenue growth: if revenue climbs but margin shrinks, you're investing heavily in acquisition or infrastructure; if revenue and margin rise together, you're scaling efficiently.

Watch-outs

• Forgetting EBITDA sits before financing and accounting. A company with strong EBITDA can still fail if debt service is crushing or the tax bill is large — always pair EBITDA with debt levels and free cash flow.
• Comparing EBITDA margins across stages as if they're equivalent. Early-stage companies run negative margins by design (heavy investment) while mature SaaS runs positive; benchmarking a seed company against a mature competitor is apples-to-oranges.
• Slipping one-time or non-recurring charges into standard EBITDA without flagging them. Severance, asset sales, and litigation settlements distort period-over-period comparison — if you remove them, label the result 'adjusted EBITDA' so readers know which number they're seeing.
• Reading the sign of EBITDA without decomposing it. Negative EBITDA from rising revenue (growth-mode spending) is a very different story from negative EBITDA on declining revenue (an alarm) — always check whether revenue or opex moved the number.
