You can calculate EBITDA from either net income or EBIT. Both methods should produce the same result when you use the same reporting period and financial statements.
The Net Income Add-Back Method
Use this EBITDA formula when you start with the bottom line of your income statement:
EBITDA = Net Income + Interest Expense + Taxes + Depreciation + Amortization
Net income already includes all five items. You add them back to show earnings before financing costs, income taxes, and non-cash charges for long-term assets.
Be sure to use interest expense, not interest income. Add income tax expense shown for the period, whether your business paid the tax during that period or recorded it as a future obligation.
Also make sure that depreciation and amortization do not appear twice. Some businesses include these in cost of goods sold or operating expenses, and then list the total separately in the cash flow statement.
The EBIT Add-Back Method
Using the formula below, your calculation can also begin with EBIT, which often appears on the income statement as operating income or operating profit, although company labels can differ:
EBITDA = EBIT + Depreciation + Amortization
This method is shorter because EBIT already excludes interest expense and taxes. You only add back depreciation and amortization.
Depreciation records the declining accounting value of physical assets, such as equipment, vehicles, and buildings. Amortization applies to certain nonphysical assets, such as patents, software costs, and customer-related assets.
Check to confirm what your EBIT figure includes. If it contains unusual income or costs, such as a lawsuit settlement or asset sale, you may want to track those items separately rather than treating them as normal operating results.
EBITDA and EBIT Calculation Examples
Assume your income statement reports the following annual figures:
Item
| Amount
|
Net income
| $180K
|
Interest expense
| $25K
|
Income tax expense
| $45K
|
Depreciation
| $30K
|
Amortization
| $10K
|
Here’s the EBITDA calculation: $180K + $25K+ $45K + $30K + $10K = $290K EBITDA
If your business instead reports EBIT of $250K, you can confirm the same result: $250K + $30K depreciation + $10K amortization = $290K
EBITDA does not equal cash flow. Your business still needs cash to pay interest and taxes as well as to replace equipment, repay debt, and fund working capital.
