EBITDA is a calculation you do yourself using numbers from your financial statements

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. You calculate it by taking your net income (the bottom line of your profit and loss statement) and adding back four specific costs that reduce that number. You are not requesting EBITDA from anyone or filling out a form — you are performing arithmetic on numbers your business already has.

The reason businesses calculate EBITDA is to show what cash the business generates from operations, separate from how it is financed (interest), taxed, or how its assets are accounted for (depreciation and amortization). Lenders, investors, and business buyers often ask for EBITDA because it lets them compare businesses that have different tax situations, debt levels, or asset structures.

You will need your profit and loss statement (also called an income statement) for the period you want to measure — usually a full year, but sometimes a quarter or month. If you use accounting software like QuickBooks, Xero, or FreshBooks, you can pull this statement directly. If you keep records manually, you will need to gather your revenue and expense records for that period.

Key Takeaways

  • EBITDA is a four-step calculation: start with net income, then add back interest expense, income tax expense, depreciation, and amortization.
  • You need your profit and loss statement and a list of depreciation and amortization amounts, which your accountant or accounting software can provide.
  • Different businesses calculate EBITDA differently depending on what they count as operating expenses, so always document your method if you are showing EBITDA to others.
  • EBITDA is useful for comparing business performance or showing cash generation, but it does not replace net income or cash flow statements for understanding true financial health.

The four numbers you add back to net income

Start with your net income — the profit or loss at the bottom of your profit and loss statement. Then add back these four items in order:

Interest expense is what you paid to borrow money. This appears on your P&L as a line item, usually near the bottom. If you have a business loan, line of credit, or credit card debt, the interest you paid goes here.

Income tax expense is the federal, state, or local income tax your business owed for that period. This is the tax line on your P&L, not the payroll taxes you withheld from employees. If your business is a sole proprietorship or partnership, you may not have a separate income tax line — in that case, this number is zero.

Depreciation is the accounting method that spreads the cost of equipment, vehicles, or buildings over several years. Your accountant or accounting software calculates this and lists it on your P&L. A $10,000 piece of equipment might be depreciated at $2,000 per year for five years.

Amortization works the same way as depreciation but applies to intangible assets like patents, software licenses, or goodwill (the premium you paid when you bought another business). If you have none of these, amortization is zero.

Where to find these numbers on your financial records

If you use accounting software, run a Profit and Loss report for the time period you want. Most software labels this as "Income Statement" or "P&L Statement." The report will show net income at the bottom and usually lists interest and tax expense separately. Depreciation and amortization may appear on the P&L or on a separate Balance Sheet or Fixed Assets report.

If your accountant prepares your taxes, they have already calculated depreciation and amortization. Ask them for a schedule showing these amounts for the year. They can also confirm your interest and tax expense from your tax return.

If you keep records manually or in a spreadsheet, gather your revenue total and all expense totals for the period. Subtract expenses from revenue to get net income. Then list any interest you paid (loan payments, credit card interest), any income tax you paid or owed, and ask yourself whether you own any equipment, vehicles, or intangible assets that should be depreciated. If you are unsure, a bookkeeper or accountant can review your records and calculate these for you.

The EBITDA formula written out

The calculation looks like this:

EBITDA = Net Income + Interest Expense + Income Tax Expense + Depreciation + Amortization

Example: A small consulting business has a net income of $50,000 for the year. It paid $3,000 in interest on a business loan, owed $8,000 in income tax, had $2,000 in depreciation on office equipment, and $500 in amortization on software licenses.

EBITDA = $50,000 + $3,000 + $8,000 + $2,000 + $500 = $63,500

This means the business generated $63,500 in operating cash before financing costs, taxes, and non-cash charges. That is higher than the net income of $50,000 because you added back the costs that reduced net income but are not cash outflows in that exact year (depreciation and amortization) or are financing decisions rather than operating performance (interest and taxes).

Why EBITDA matters and what it does not tell you

EBITDA is useful when you are comparing your business to competitors, showing performance to potential investors or buyers, or tracking whether your operations are generating cash. A lender might ask for EBITDA to see whether your business can cover debt payments. A buyer might use EBITDA to value your business as a multiple — for example, "this type of business sells for 4 times EBITDA," so a $63,500 EBITDA business might be worth around $254,000.

EBITDA does not tell you whether you have enough cash in the bank, whether you can pay your bills next month, or whether your business is truly healthy. It removes taxes and financing costs, which are real expenses you actually pay. It also ignores changes in inventory, accounts receivable, or accounts payable — all of which affect whether you have cash on hand. For those reasons, EBITDA should always be looked at alongside your cash flow statement and balance sheet, not instead of them.

Different businesses and accountants sometimes calculate EBITDA differently, especially when deciding what counts as an operating expense versus a one-time charge. If you are showing EBITDA to a lender or buyer, document exactly how you calculated it and what you included and excluded. This transparency prevents misunderstandings later.

Common mistakes when calculating EBITDA

The most common error is forgetting to add back all four items. Some business owners add back interest and taxes but forget depreciation, or vice versa. Check your P&L line by line to make sure you have captured each one.

Another mistake is confusing depreciation with a cash expense. Depreciation is not money you paid out this year — it is an accounting entry that spreads a past purchase across multiple years. That is exactly why you add it back: it reduced your net income but did not reduce your cash. The same is true for amortization.

A third error is including items that should not be in EBITDA. For example, if you had a one-time gain from selling equipment or a lawsuit settlement, those are not operating expenses and should not be added back. EBITDA is meant to show operating performance, so stick to the four categories: interest, taxes, depreciation, and amortization.

Finally, some business owners calculate EBITDA from a single month and assume it represents the whole year. Monthly EBITDA can be lumpy — one month might have a large equipment purchase (depreciation spike) or a tax payment. For a true picture, calculate EBITDA for a full year or at least a full quarter.

Frequently Asked Questions

Do I need an accountant to calculate EBITDA?

No. If you have a profit and loss statement and know your depreciation and amortization amounts, you can calculate EBITDA yourself with a calculator. Your accountant can confirm the numbers are correct and help you gather depreciation schedules, but the math is straightforward addition.

What if my business has no depreciation or amortization?

Then those numbers are zero and you simply do not add them. EBITDA = Net Income + Interest + Taxes. Many service businesses with few physical assets fall into this category.

Can EBITDA be negative?

Yes. If your net income is negative (your business lost money), EBITDA can also be negative even after adding back interest, taxes, depreciation, and amortization. A negative EBITDA means your operations are not generating cash.

Is EBITDA the same as cash flow?

No. EBITDA removes non-cash charges like depreciation, but it does not account for changes in working capital (inventory, receivables, payables) or capital expenditures (new equipment purchases). Cash flow is what actually moved in and out of your bank account. You need both numbers for a complete picture.

Why would a lender ask for EBITDA instead of net income?

Because EBITDA shows operating performance independent of how the business is financed or taxed. Two identical businesses with different debt levels or tax situations will have different net incomes but the same EBITDA, making them easier to compare. Lenders use EBITDA to assess whether operations can support a loan payment.
