What EBITDA margin means

EBITDA — Earnings Before Interest, Tax, Depreciation & Amortisation — is a checkpoint one step further down the waterfall than gross profit: revenue, minus the direct cost of what was sold (COGS), minus the day-to-day cost of running the business (salaries, distribution, admin), but before the company’s financing decisions (interest), tax, or the accounting effect of its assets ageing (depreciation) enter the picture. We defined the full waterfall in Reading an Income Statement — EBITDA margin is just that EBITDA line expressed as a percentage of revenue.

The point of stopping here specifically: it’s the cleanest read on how the core operating business is doing, stripped of two things that have nothing to do with how good the business itself is — how it’s financed (debt vs equity) and how its accountants choose to depreciate its assets.

The formula

EBITDA Margin (%) = EBITDA / Revenue × 100

Worked example: Desi Bites Foods, FY25

  ₹ Lakh
Revenue 2592
EBITDA 441
EBITDA Margin 17.0%

Worked example: Britannia Industries, FY25

Same source as always for the real-company half of this series: Britannia Industries’ audited consolidated results for FY25 (year ended 31 March 2025, filed 8 May 2025). For illustration only, not a signal to act on.

  ₹ Crore
Revenue from operations 17942.67
EBITDA (revenue − COGS − operating opex) 3187.15
EBITDA Margin 17.8%

FY24’s EBITDA margin, from the same filing, was 18.9% — again a touch richer than FY25. That tracks the same story as Gross Margin: the compression starts at the raw-material line and mostly carries through, since operating expenses (the other thing between gross profit and EBITDA) moved by less.

Common mistakes

  • Treating EBITDA margin as a cash margin. EBITDA excludes depreciation because it’s a non-cash accounting entry — but that doesn’t mean EBITDA is cash. Working capital changes (unpaid customer invoices, growing inventory) can still mean healthy EBITDA and weak actual cash — that’s what the cash flow statement is for.
  • Using it to compare companies with very different asset intensity. A company that leases most of its equipment and a company that owns a heavy factory outright can show similar EBITDA margins while having very different real economics — depreciation (which EBITDA ignores) is exactly where that difference would show up.
  • Ignoring debt entirely because EBITDA excludes interest. EBITDA margin tells you nothing about whether a company can actually service its debt — a highly leveraged company can have a great EBITDA margin and still be in financial trouble once interest and debt repayment are due.
  • Reading a single year as the whole story. As with gross margin, one year’s EBITDA margin can move on input costs alone — worth checking against at least one prior year, as above, before drawing a conclusion.

Takeaway: EBITDA margin isolates how the core operating business is doing, before financing and depreciation choices — useful for comparing operating performance, but it is not a cash number and says nothing about a company’s ability to service its debt.
