What EBITDA Calculator does, with a checked example

Start with reported earnings and bridge to EBITDA by adding back interest, income taxes, depreciation, and amortization. The calculator can then incorporate separately entered adjustments, express the result as a percentage of revenue, and divide enterprise value by EBITDA for valuation comparison. The common trap is mixing bases: an adjusted EBITDA figure should not be compared with an unadjusted figure, and a multiple based on enterprise value is not the same as a price-to-earnings ratio.

Worked example

A concrete input and expected output from the current implementation.

Input

Revenue: $1,000,000
Net income: $120,000
Interest expense: $30,000
Income tax expense: $40,000
Depreciation: $25,000
Amortization: $5,000
Add-back adjustments: $20,000
Enterprise value: $1,200,000

Expected output

EBITDA: $220,000; EBITDA margin: 22.00%; adjusted EBITDA: $240,000; adjusted EBITDA margin: 24.00%; EV/EBITDA: 5.45x; EV/adjusted EBITDA: 5.00x.

Base EBITDA is $120,000 + $30,000 + $40,000 + $25,000 + $5,000 = $220,000. Adding $20,000 produces $240,000; dividing each result by $1,000,000 gives the margins, while dividing $1,200,000 by each result gives the multiples.

How the result is produced

1

Earnings bridge

The earnings bridge begins with net income and adds interest expense, income tax expense, depreciation, and amortization for the same reporting period. The sum is base EBITDA. Separately entered add-back adjustments are then added to base EBITDA to produce adjusted EBITDA, allowing the unadjusted and adjusted results to remain distinct in the comparison.

Margins and multiples

EBITDA margin equals EBITDA divided by revenue and is shown as a percentage. EV/EBITDA equals enterprise value divided by EBITDA and is shown as a multiple; using adjusted EBITDA produces a separate adjusted multiple. This differs from ratios that compare equity value with earnings available to common shareholders.

Good uses

  • Reconcile reported net income to base and adjusted EBITDA before reviewing a lending covenant.
  • Compare EBITDA margins for two periods using each period's revenue and earnings data.
  • Test how a proposed enterprise value translates into base and adjusted EV/EBITDA multiples during an acquisition review.

Limits and checks

  • EBITDA and adjusted EBITDA are non-GAAP measures, so companies may define or label adjustments differently.
  • Positive EBITDA does not establish positive cash flow because working capital, capital spending, and debt principal payments are outside the measure.
  • A meaningful comparison requires revenue, earnings components, adjustments, and enterprise value to refer to compatible dates and periods.

Common questions

Should depreciation and amortization be added back if they are already combined?

Yes, but only once. Enter the combined D&A amount in a combined field if available, or split it between depreciation and amortization so the two entries sum to the reported total. Do not enter the combined total and repeat its components, because that would overstate EBITDA.

Does a lower EV/EBITDA multiple always mean the business is cheaper?

No. The multiple is only a ratio of enterprise value to the selected EBITDA measure. Differences in growth, risk, accounting policies, lease treatment, cyclicality, and adjustment choices can make two multiples non-comparable. The ratio is also undefined when EBITDA is zero and usually unhelpful when EBITDA is negative.
