What is EBITDA?
The EBITDA calculator above computes Earnings Before Interest, Taxes, Depreciation, and Amortization by adding those four items back to net income. EBITDA is one of the most widely used — and widely debated — measures of business performance. Its purpose is to show the underlying operating profitability of a business, stripped of decisions about financing (interest), the tax environment (taxes), and non-cash accounting charges (depreciation and amortization).
The appeal is comparability. Two businesses might have identical operations but very different net incomes simply because one carries debt and the other doesn’t, or one operates in a high-tax jurisdiction, or one recently bought expensive equipment it must depreciate. EBITDA removes those differences so you can compare the core earning power of the businesses themselves. This is why EBITDA dominates valuation multiples and lending decisions.
The formula
EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization- Net income — the bottom-line profit after everything.
- Interest — interest expense on debt (a financing choice).
- Taxes — income taxes paid.
- Depreciation — the non-cash expense spreading the cost of physical assets over time.
- Amortization — the same idea for intangible assets.
You add these four back to net income because each reflects financing, tax, or accounting decisions rather than core operating performance.
Worked example
Net income $500,000, interest $50,000, taxes $120,000, depreciation $80,000, amortization $30,000:
EBITDA = $500,000 + $50,000 + $120,000 + $80,000 + $30,000 = $780,000The business produced $780,000 in operating earnings before financing, tax, and non-cash charges — substantially more than its $500,000 net income. That $280,000 difference is exactly what EBITDA is designed to surface: the portion of operating performance that net income obscures because of how the company is financed, taxed, and depreciating its assets.
In valuation, this matters directly. If similar businesses sell for 8x EBITDA, this company would be valued around $6.24M on EBITDA — versus $4M if someone naively applied the same multiple to net income. Using the right earnings base is the difference between a fair price and a costly mistake.
Benchmarks
EBITDA itself isn’t benchmarked as a raw number — it scales with company size — but two derived measures are:
- EBITDA margin (EBITDA ÷ revenue): commonly 10–20% for healthy businesses, higher for software and asset-light models.
- EBITDA multiple (valuation ÷ EBITDA): private businesses often transact at 3–10x EBITDA depending on size, growth, and industry; larger, faster-growing companies command higher multiples.
How to interpret it — and its limits
EBITDA is best read as an approximation of operating cash flow that enables apples-to-apples comparison. A rising EBITDA margin signals improving operating efficiency; a healthy EBITDA multiple anchors a valuation conversation.
But EBITDA has a famous blind spot, and ignoring it is dangerous. By adding back depreciation, EBITDA pretends capital expenditure doesn’t exist — yet a manufacturer or infrastructure business must constantly reinvest in equipment that wears out. For such businesses, EBITDA dramatically overstates the cash actually available to owners. Warren Buffett’s well-known criticism is exactly this: “Does management think the tooth fairy pays for capital expenditures?” EBITDA also ignores changes in working capital, which can consume cash even in a profitable, growing business.
The practical rule: EBITDA is excellent for comparing operating performance across companies with different capital structures, but never mistake it for free cash flow. For an asset-heavy business, always look at EBITDA minus capital expenditure to see what’s really left.
Frequently asked questions
What is EBITDA? EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It is calculated by adding those four items back to net income, producing a measure of operating profitability that strips out financing structure, tax environment, and non-cash accounting charges.
Why is EBITDA used? EBITDA approximates operating cash flow and lets you compare the core profitability of businesses with different debt loads, tax situations, and asset bases. It is widely used in valuation (EBITDA multiples) and lending, though it can overstate cash flow because it ignores capital expenditure and working capital needs.
