EBIDA (earnings before interest, depreciation and amortization) is a profit measure that takes net income and adds back interest expense, depreciation and amortization, while leaving income tax expense deducted. It is EBITDA with taxes kept as a cost. EBIDA is never higher than EBITDA when a company records a tax expense, so it gives a more conservative view of profitability. It is far less widely used than EBITDA.

How EBIDA Works

EBIDA starts from an accounting result and strips out three expenses. Interest is a financing cost that depends on how much the company borrows. Depreciation and amortization are non-cash charges that spread the cost of physical and intangible assets over their useful lives. Removing them shows earnings closer to what the business generates from operations, after it has paid its taxes.

Everything needed for the calculation appears on the income statement. Depreciation and amortization are sometimes combined into one line, or appear only in the cash flow statement or the notes.

Calculating EBIDA

There are three equivalent ways to get the figure, depending on your starting point:

1. From net income: EBIDA = Net income + Interest expense + Depreciation + Amortization
2. From EBIT (operating income): EBIDA = EBIT + Depreciation + Amortization − Income taxes
3. From EBITDA: EBIDA = EBITDA − Income taxes

Net income is the most convenient starting point because every company reports it. The EBIT route suits companies that report operating income separately. If the company has other non-operating income or expenses (gains on asset sales, investment income), routes 1 and 2 will differ unless you treat those items consistently, so apply one definition to every company you compare.

Example of EBIDA

Consider a hypothetical manufacturer with the following annual figures:

• Revenue: $2,400,000
• Cost of goods sold: $1,100,000
• Selling, general and administrative expenses: $450,000
• Depreciation: $180,000
• Amortization: $40,000
• Interest expense: $130,000
• Income tax expense: $100,000

Net income is revenue minus all expenses: $2,400,000 − $1,100,000 − $450,000 − $180,000 − $40,000 − $130,000 − $100,000 = $400,000.

EBIDA adds back interest, depreciation and amortization: $400,000 + $130,000 + $180,000 + $40,000 = $750,000.

Checking with the EBIT route gives the same answer. EBIT is $2,400,000 − $1,100,000 − $450,000 − $220,000 = $630,000. Then $630,000 + $220,000 − $100,000 = $750,000.

For comparison, EBITDA is $850,000, because it also adds back the $100,000 tax expense. The $350,000 gap between net income and EBIDA shows how much interest and non-cash asset charges reduce reported earnings. The $100,000 gap between EBIDA and EBITDA is the tax bill.

How EBIDA Is Used

Comparing companies with different financing. Adding interest back removes the effect of capital structure, so a heavily indebted company and a debt-free one can be compared on the earnings their operations produce. This works best within one industry, where depreciation and tax profiles are similar.

Keeping taxes in the picture. EBITDA treats taxes as if they were not an operating cost. EBIDA does not. Taxes are a recurring cash cost for profitable companies, so EBIDA is a stricter test, most useful when comparing companies with different tax rates, a difference EBITDA hides. Because interest is tax deductible, a company’s tax bill is partly a product of its borrowing, and EBITDA’s add-back of taxes can flatter a leveraged business. EBIDA keeps the reported tax expense as a deduction, so its result is lower. One subtlety: the tax figure EBIDA keeps was calculated after the interest deduction, so EBIDA is not a fully “unlevered, after-tax” number either.

Tax-exempt organizations. Nonprofit hospitals, universities and charities generally pay no income tax, so the “T” in EBITDA has nothing to remove. EBIDA is the natural description of their pre-interest, pre-depreciation earnings, and for them the two measures are interchangeable.

Interpreting EBIDA

There is no universal “good” EBIDA. The number scales with company size, so it is more useful as a margin (EBIDA ÷ revenue) or as a trend over several periods. In the example above, the EBIDA margin is $750,000 ÷ $2,400,000 = 31.25%. A rising margin means operations are producing more after-tax earnings per dollar of sales, before financing and asset charges.

A positive EBIDA is a minimum condition, not proof of health. Because depreciation and amortization are added back, a company can report positive EBIDA and still post a net loss every year if its asset charges and interest are large enough.

EBIDA vs. EBITDA, EBIT and Net Income

The only difference between EBIDA and EBITDA is the treatment of income taxes: EBITDA adds them back, EBIDA leaves them deducted. When a company has a positive tax expense, EBIDA is lower. When it has a tax benefit (a negative tax expense), EBIDA can be higher. EBIDA is usually above EBIT, because the depreciation and amortization it adds back tend to exceed the taxes it subtracts, but that depends on the company.

Limitations of EBIDA

• No standard definition. EBIDA is a non-GAAP measure. Two analysts can include or exclude items differently, so figures from different sources may not be comparable.
• Rarely reported. Because EBITDA and EBIT dominate analyst reports and loan covenants, you will usually have to calculate EBIDA yourself.
• Not cash flow. It ignores capital expenditures, changes in working capital and the cash actually spent on interest. Depreciation is non-cash in the period it is recorded, but the assets behind it had to be paid for and will have to be replaced. Free cash flow captures those outflows.
• Can overstate earning power. Since EBIDA sits above net income, presenting it on its own can make a company look more profitable than its bottom line shows, especially in asset-heavy or highly leveraged businesses.

The Bottom Line

EBIDA suits analysts comparing companies with different debt loads or tax rates, and it describes the earnings of tax-exempt nonprofits that pay no income tax. Since it is non-GAAP and rarely reported, you will usually calculate it yourself and should apply one definition consistently. Treat a positive figure as a minimum condition, and check net income and free cash flow before judging profitability.
