EBITDA Explained: What It Is, What It Hides

EBITDA stands for earnings before interest, taxes, depreciation and amortization, and it is a measure of operating profit before financing choices, tax regimes and accounting write-offs of long-lived assets. Lenders, buyers and boards use it because it makes companies with different debt, tax and asset structures easier to compare. It is also one of the most abused numbers in business, because it ignores several things that cost real money: capital spending, working capital, interest and tax. This guide explains what EBITDA is, shows two ways to calculate it with checked arithmetic, covers the common adjustments and where they go wrong, and compares two companies with identical EBITDA and very different cash. It belongs to unit economics and budgeting and forecasting, builds on net profit margin and gross margin, and leads to EBITDA vs. net income and operating margin.

What EBITDA measures

EBITDA is operating profit with depreciation and amortization added back. In other words, it shows what the business earns from operations before:

• Interest, which depends on how the business is financed.
• Taxes, which depend on jurisdiction, structure and history.
• Depreciation and amortization, which spread the past cost of long-lived assets over time and are non-cash charges.

The idea is to isolate the earning power of operations. A company with a lot of debt and a company with none, or a company that owns its warehouse and one that rents, look more alike on EBITDA than on net income.

Two ways to calculate it

Use the hypothetical company from the net profit margin example: revenue $4,000,000, net income $330,000, interest $60,000, income tax $110,000, depreciation and amortization $150,000 (included in operating expenses).

Bottom-up, from net income:

EBITDA = Net income + Interest + Taxes + Depreciation and amortization = 330,000 + 60,000 + 110,000 + 150,000 = $650,000

Top-down, from operating income:

Operating income = $500,000, which already includes the $150,000 of depreciation as an expense. EBITDA = Operating income + Depreciation and amortization = 500,000 + 150,000 = $650,000

Both give the same answer, which is a good check. EBITDA margin = 650,000 / 4,000,000 = 16.25%.

If your income statement includes other non-operating items, such as gains on asset sales or investment income, take them out so that EBITDA reflects operations.

Why people use it

For example, at an illustrative multiple of 6 times, the company above would be valued at an enterprise value of 6 × 650,000 = $3,900,000. Multiples vary with industry, growth, size and market conditions, so the 6 is an assumption for the sake of the example and not a benchmark.

What EBITDA hides

EBITDA leaves out costs that a business must pay in cash. This is the central issue.

Capital spending

Depreciation is added back, but the cash spent on equipment, vehicles, buildings and software development is not in EBITDA at all. Two companies with the same EBITDA may need very different amounts of reinvestment.

Compare Company A and Company B, each with EBITDA of $650,000, interest of $60,000 and tax of $110,000 (illustrative figures):

Check: A = 650 - 100 - 60 - 110 - 50 = 330. B = 650 - 450 - 60 - 110 - 50 = -20 (thousands).

With identical EBITDA, Company A generates $330,000 of cash and Company B consumes $20,000. EBITDA alone cannot tell them apart.

Working capital

Growth in inventory and receivables uses cash but does not reduce EBITDA. A product company that grows 20 percent a year may need to fund extra inventory that is far larger than its profit increase. Inventory that cannot be sold is eventually written down, which reduces profit later, but the cash is gone sooner. See cash flow management and demand planning and inventory optimization.

Interest and taxes

These are real cash costs. Debt service must be paid from cash flow, not from EBITDA. A highly indebted company can have strong EBITDA and still struggle.

Stock-based pay and other non-cash costs

Some companies add back share-based compensation as non-cash. It is a real cost to owners through dilution. Treat such add-backs with skepticism, and look at how they are described.

Adjusted EBITDA

Companies often report adjusted EBITDA, which adds back items management calls unusual or non-recurring. Some adjustments are reasonable and some are not.

A useful test: would the cost have been needed to earn the revenue? If yes, it belongs in EBITDA. Ask for a bridge from reported to adjusted figures, with support for each line, and track the size of adjustments as a percentage of EBITDA over time. A growing gap is a warning.

A practical bridge for monthly reporting

Show EBITDA and its bridge to cash each month: EBITDA, minus change in inventory, minus change in receivables, plus change in payables, minus capital expenditure, minus interest and tax, equals net cash flow before financing. Owners of product businesses are often surprised to find that the inventory line is the largest difference between EBITDA and cash. Forecast it explicitly. See budgeting and forecasting.

Common mistakes

• Treating EBITDA as cash flow.
• Comparing EBITDA across companies with different capital intensity without looking at capex.
• Accepting adjusted EBITDA without a bridge.
• Using EBITDA to assess product or customer profitability, where contribution is more useful.
• Ignoring leases. Rent counts as an operating expense in EBITDA under some accounting rules and as depreciation and interest under others, so comparisons need care.
• Quoting a multiple without stating whether it uses reported or adjusted figures.

EBITDA to cash for a product company

For a company that holds inventory, the walk from EBITDA to cash is where the surprises are. Take the company with EBITDA of $650,000. During the year it grew, so inventory rose by $300,000, receivables by $80,000, and payables by $120,000. Capital spending was $100,000, interest $60,000 and tax $110,000.

Cash flow before financing = 650,000 - 300,000 - 80,000 + 120,000 - 100,000 - 60,000 - 110,000 = $120,000.

Only about 18 percent of EBITDA (120,000 / 650,000) turned into cash. The largest single difference was the $300,000 increase in inventory. If the company had planned inventory more tightly and grown stock by $150,000 instead, cash flow would have been $270,000. That kind of improvement does not show in EBITDA at all, which is why finance and supply chain teams should look at the bridge together. See cash flow management and demand planning and inventory optimization.

Leases and EBITDA

Accounting rules treat leases differently. Under some standards, most leases are recorded as an asset with depreciation and interest, which lifts EBITDA because the rent no longer appears as an operating expense. Under others, operating leases remain a rent expense inside EBITDA. Two companies with the same real rent can show different EBITDA depending on the rules they follow. When comparing, put leases on the same basis, or look at EBITDA after rent. Ask a lender or buyer which definition applies in their documents.

Five rules for using EBITDA well

1. Always show the bridge from net income, and from EBITDA to cash.
2. Show EBITDA less capital expenditure next to EBITDA for capital-intensive businesses.
3. Track the size of adjustments as a percentage of EBITDA, and challenge any growth.
4. Use EBITDA for comparison and covenants, not for judging products or customers.
5. Never describe EBITDA as cash flow.

FAQs

What is EBITDA?

Earnings before interest, taxes, depreciation and amortization. It measures operating profit before financing, tax and non-cash write-offs of long-lived assets.

How do you calculate EBITDA?

Add interest, taxes, depreciation and amortization to net income, or add depreciation and amortization to operating income.

Is EBITDA the same as cash flow?

No. EBITDA ignores capital spending, working capital, interest and taxes, all of which affect cash.

What is a good EBITDA margin?

It depends on industry and business model. Compare it with your own history and your needs for reinvestment and debt service.

What is adjusted EBITDA?

EBITDA after adding back items management considers unusual or non-recurring. Always ask for a reconciliation and test whether the items recur.
