EBITDA is net income plus four specific line items from your financial statements
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. To calculate it, you start with your net income (the bottom line of your income statement) and add back four expenses that were already subtracted to get there: interest expense, income tax expense, depreciation, and amortization. The result is what your business earned from operations before financing decisions and accounting methods changed the number.
The formula looks like this: Net Income + Interest + Taxes + Depreciation + Amortization = EBITDA. Every number comes from your company's financial statements — usually the income statement and the cash flow statement. You do not need to estimate or calculate anything new; you are reassembling numbers that already exist.
EBITDA is useful because it shows operating performance without the noise of how a company is financed (interest), taxed (which varies by location and structure), or how it accounts for asset wear (depreciation and amortization). Two companies with identical operations but different debt levels or tax situations will have different net incomes but the same EBITDA.
Key Takeaways
- EBITDA starts with net income and adds back interest, taxes, depreciation, and amortization — all four items must be included for the standard calculation.
- All four numbers come directly from your income statement or cash flow statement; you are not estimating or creating new figures.
- EBITDA removes the effect of financing choices (debt level), tax jurisdiction, and accounting method, making it easier to compare operating performance between companies.
- The calculation is the same whether you are analyzing a small business or a large corporation, though larger companies may have more complex line items to track.
- EBITDA is not a substitute for net income or cash flow; it is one lens on financial performance and is often used alongside other metrics.
Where to find each number on your financial statements
Your income statement lists net income at the bottom, usually labeled "Net Income" or "Net Profit." This is your starting point. On the same statement, you will find interest expense (often under "Other Expenses" or "Interest Expense") and income tax expense (usually a separate line near the bottom, before net income is calculated).
Depreciation and amortization appear in two places. They are listed as expenses on the income statement (which is why net income is already reduced by them), and they also appear on the cash flow statement under "Operating Activities" as a non-cash expense that is added back. Using the cash flow statement is often simpler because both depreciation and amortization are usually grouped together on one line.
If your company uses accounting software (QuickBooks, Xero, FreshBooks), you can pull these numbers from the standard income statement and cash flow statement reports. If you are working from tax returns, the same line items appear on the business tax form (Form 1120 for corporations, Schedule C for sole proprietors).
The order does not matter, but the math must be exact
You can add the four items in any order — the result is the same. Some people add them all at once; others add them one at a time. What matters is that you include all four and that you use the correct sign (positive or negative) for each.
Interest expense, taxes, depreciation, and amortization are all subtracted to get to net income, so you add them back as positive numbers. If any of these is negative (for example, a company with a tax refund instead of a tax bill), you subtract it instead. Most of the time, all four are positive, and you simply add them to net income.
A common mistake is forgetting one of the four items or using the wrong number (for example, using total interest paid instead of interest expense, or using book depreciation instead of tax depreciation). Double-check that you have all four before you finalize the number.
Example: calculating EBITDA for a real business
Suppose a small manufacturing company has these numbers from its most recent income statement:
| Line Item | Amount |
| Net Income | $150,000 |
| Interest Expense | $25,000 |
| Income Tax Expense | $40,000 |
| Depreciation | $35,000 |
| Amortization | $10,000 |
The calculation is: $150,000 + $25,000 + $40,000 + $35,000 + $10,000 = $260,000 EBITDA. This means the company generated $260,000 from operations before paying interest on debt, taxes to the government, and before accounting for the wear on equipment and intangible assets. The net income of $150,000 is what was left after all those items were paid or recorded.
If you were comparing this company to a competitor with the same revenue but higher debt (and therefore higher interest expense), the competitor's net income would be lower, but the EBITDA would be the same if operations are identical. That is why EBITDA is useful for comparing companies with different capital structures.
When depreciation and amortization are zero
Some businesses have no depreciation or amortization — for example, a service company with no equipment and no intangible assets. In that case, you still include both in the formula; they are just zero. The calculation still works: Net Income + Interest + Taxes + 0 + 0 = EBITDA.
A business might also have depreciation but no amortization, or vice versa. Again, include both in the formula and use zero for whichever does not apply. This keeps the calculation consistent across all companies.
EBITDA margin: putting the number in context
EBITDA by itself is a dollar amount, which is hard to compare across companies of different sizes. EBITDA margin is EBITDA divided by total revenue, expressed as a percentage. It shows what portion of every dollar of sales becomes operating profit.
If the manufacturing company above had $1,000,000 in revenue, its EBITDA margin would be $260,000 ÷ $1,000,000 = 26%. This means 26 cents of every dollar of sales became operating profit. A competitor with a 20% EBITDA margin is converting less of its revenue to operating profit, even if both companies have the same total EBITDA.
EBITDA margin is often used to compare performance over time (is this year's margin better than last year's?) or to benchmark against industry averages. It removes the effect of company size, making it easier to spot trends.
Frequently Asked Questions
Can EBITDA be negative?
Yes. If a company loses money (negative net income) and the four add-backs do not exceed that loss, EBITDA will be negative. This means the company is not generating profit from operations, even before financing and tax effects. A negative EBITDA is a warning sign that the core business is unprofitable.
Is EBITDA the same as cash flow?
No. EBITDA is an accounting measure based on income statement line items. Cash flow is actual money in and out of the business. Depreciation and amortization are added back in EBITDA because they are non-cash expenses, but EBITDA does not account for changes in working capital, capital expenditures, or debt payments — all of which affect cash flow.
Why do lenders and investors care about EBITDA?
Lenders use EBITDA to estimate how much cash a company has available to pay debt. Investors use it to compare operating performance across companies with different tax situations or debt levels. EBITDA is not perfect, but it removes some of the noise that makes net income hard to compare.
Should I use EBITDA or net income to run my business?
Use both. Net income tells you what you actually earned after all expenses and obligations. EBITDA tells you how your core operations are performing. If EBITDA is strong but net income is weak, you have a financing or tax problem. If both are weak, your operations need work.
What if my company has no interest expense?
Include it in the formula as zero. The calculation is still Net Income + 0 + Taxes + Depreciation + Amortization = EBITDA. A company with no debt has no interest expense, but you still follow the same formula for consistency.
