How to Calculate EBITDA: Formula, Examples and Worksheet

EBITDA is a financial measure used to examine earnings before interest, taxes, depreciation and amortization. To calculate it, start with a clearly defined financial period, use a consistent set of financial statements, and add the relevant items back to net income—or start with EBIT and add depreciation and amortization. The arithmetic is straightforward; making sure the inputs are consistent and supported is the more important part.

This guide provides the formulas, a worked example, a margin calculation, a multi-year comparison and a worksheet you can use to organize the numbers. It also explains how reported EBITDA differs from adjusted EBITDA and why EBITDA is not the same as cash flow or business value. For the broader valuation framework, see EBITDA Business Valuation.

Quick answer: What is the EBITDA formula?

When starting from net income, the simplified formula is:

EBITDA = Net income + interest expense + income tax expense + depreciation + amortization

Another common route is to start with EBIT (earnings before interest and taxes):

EBITDA = EBIT + depreciation + amortization

These approaches should generally reconcile when the financial statement definitions and period are consistent. If the business reports items differently, has tax benefits rather than tax expense, or uses a pass-through tax structure, confirm the correct treatment with the company’s accountant before relying on the result.

The two methods are alternatives, not amounts to add together. Do not calculate EBITDA from net income and then add the same interest, tax, depreciation or amortization a second time.

Worked example: Calculate EBITDA from net income

Suppose a company reports the following figures for one completed financial year. These amounts are hypothetical and demonstrate the arithmetic only.

The calculation is $300,000 + $30,000 + $70,000 + $40,000 + $10,000 = $450,000. Based on the stated inputs, the company’s EBITDA for this period is $450,000.

Before using the result, reconcile each amount to the relevant financial statement and supporting records. This example assumes the income tax expense shown is the relevant amount for the calculation. It is not a rule that every tax payment, owner tax distribution or tax-related entry should be added back.

Step-by-step: How to calculate EBITDA correctly

Step 1: Choose a consistent period

Decide whether you are calculating EBITDA for a fiscal year, calendar year, quarter, or trailing 12-month period. Use figures from the same period and accounting basis. Do not combine 12 months of revenue with six months of expenses or mix interim figures with full-year amounts without a clear reconciliation. If the business is seasonal, one period may not tell the full story.

Step 2: Find net income or EBIT

Start with the relevant income statement. Net income is generally the profit after expenses, interest and income taxes shown in the statement. EBIT is earnings before interest and taxes. Confirm how the company labels and presents these figures; do not assume similarly named lines are defined identically across different accounting reports.

Step 3: Identify interest expense

If using the net-income method, add back the relevant interest expense included in the earnings figure. Review the general ledger or debt schedules if several accounts are involved. Be careful not to include principal repayments as interest expense: loan principal is a balance-sheet repayment, not an income-statement expense in the EBITDA formula.

Step 4: Identify applicable income tax expense

Add the relevant income tax expense used in the income statement calculation. The treatment can require extra care when a company is a pass-through entity, when owners pay personal income tax, or when the accounts show a tax benefit rather than an expense. Do not automatically add back estimated tax payments, owner distributions or every tax-related entry. Reconcile the treatment with the company’s accounting records and professional adviser.

Step 5: Add depreciation

Depreciation allocates the accounting cost of certain tangible assets across their useful lives. Find the depreciation expense for the same period in the income statement, fixed-asset schedule or supporting ledger. Adding depreciation back for EBITDA does not mean equipment is cost-free: the company may still need to maintain or replace vehicles, machinery, computers or other assets.

Step 6: Add amortization

Amortization is generally associated with allocating the cost of certain intangible assets over time. Identify the amortization expense included in the reported earnings. Use the supporting schedule where available, particularly if acquired intangible assets or several categories of amortization are involved.

Step 7: Reconcile and document the result

Add the relevant components once, check the arithmetic, and keep a short reconciliation showing where each number came from. If the result will be used in a potential sale, financing discussion or valuation analysis, preserve the underlying statements and schedules so another reviewer can trace the calculation.

How to calculate EBITDA from EBIT

You can also start with EBIT, which is earnings before interest and taxes, then add depreciation and amortization:

EBITDA = EBIT + depreciation + amortization

Here, $400,000 + $40,000 + $10,000 = $450,000. This matches the earlier example because its net income plus interest and income tax expense also equals $400,000. In actual accounts, investigate any difference between the two approaches instead of forcing them to match: presentation, non-operating items, tax benefits or data-period differences may need to be clarified.

How to calculate EBITDA margin

EBITDA margin expresses EBITDA as a percentage of revenue. It can help describe profitability and compare a company’s performance over time, provided revenue and EBITDA are measured consistently.

EBITDA margin = EBITDA ÷ Revenue × 100

For example, if revenue is $2,000,000 and EBITDA is $400,000, the calculation is $400,000 ÷ $2,000,000 × 100 = 20%. The company’s EBITDA margin for that period is 20%.

This hypothetical table shows revenue growing while the margin rises and then holds steady. The trend is a prompt for further analysis, not a conclusion by itself. Ask whether changes reflect prices, sales mix, labor costs, supplier costs, customer concentration, staffing or a one-time event.

Reported EBITDA vs. adjusted EBITDA

Reported EBITDA is calculated using the company’s reported financial information and a defined formula. Adjusted EBITDA starts with EBITDA and applies further adjustments intended to show a more representative level of continuing operating performance. The appropriate adjustments depend on the business, the purpose of the analysis and the evidence available.

Potential adjustments may involve a supported one-time expense, a non-operating item or another item that does not reflect ongoing operations. An expense does not qualify merely because management calls it unusual. The reviewer should consider whether it is genuinely non-recurring, whether an equivalent cost will recur, whether an owner’s duties will need to be replaced, and whether the adjustment is supported by documentation.

The $25,000 adjustment is hypothetical. It should only be included if an actual review establishes that it is appropriate and supportable. Do not assume all legal fees, consulting fees, owner expenses, repairs or other unusual items can be added back.

For adjustment rules and documentation, read EBITDA Add-Backs. For the separate question of how normalized EBITDA may be used in a value estimate, see EBITDA Business Valuation.

EBITDA worksheet: Record the inputs

Use this worksheet to organize a calculation. Enter amounts from a consistent period and keep a reference to the financial statement or schedule supporting each line.

If separately preparing adjusted EBITDA, use a second schedule for each proposed adjustment: date and description, amount, why it is not representative of continuing operations, supporting evidence, any replacement or recurring cost, and whether it has been accepted in the analysis. Keep reported EBITDA distinct from proposed and accepted adjustments.

Documents commonly used to calculate EBITDA

The documents needed depend on the company’s accounting system and the purpose of the calculation. Common starting records include:

• Income statements or profit-and-loss statements for the chosen period.
• Balance sheets and general-ledger detail where needed to reconcile specific accounts.
• Business tax returns and accountant-prepared financial statements, where available.
• Loan statements or schedules supporting interest expense.
• Fixed-asset and depreciation schedules, plus amortization schedules where applicable.
• Supporting invoices and explanations for any proposed normalization adjustments.
• Current-year results and comparable prior periods, especially where performance is seasonal or recently changing.

Tax returns can be useful supporting evidence, but they may not contain every detail needed for a consistent EBITDA calculation. Reconcile the number to the company’s financial statements and explain any material differences instead of assuming one document automatically provides the final answer.

Common EBITDA calculation mistakes

Mixing periods or accounting bases

Use a clearly stated period and consistent figures. If trailing 12-month numbers are used, show how they are assembled and how they relate to the latest completed financial year.

Adding the same item back twice

Do not add back an item already excluded from the starting earnings figure or already reflected in another adjustment. Maintain a reconciliation to avoid double counting.

Treating loan principal as interest

Only the relevant interest expense is added back in the standard net-income formula. Principal repayments are not interest expense and do not belong in the formula as an add-back.

Assuming every tax-related amount is an add-back

Owner distributions, estimated payments, income tax expense and tax benefits are not interchangeable. Confirm which item appears in the earnings calculation and why it belongs in the chosen formula.

Confusing EBITDA with cash flow

EBITDA does not fully reflect capital expenditure, working-capital changes, income taxes, interest or debt repayments. A business can report positive EBITDA while still requiring substantial cash to operate.

Calling an expense non-recurring without evidence

A proposed normalization adjustment needs a reasonable basis and supporting records. If the expense or the function it funds will continue, removing it may overstate sustainable earnings.

What EBITDA does—and does not—tell you

EBITDA can help describe operating earnings before interest, taxes, depreciation and amortization. It does not measure all cash available to owners, prove that earnings are sustainable, determine the value of the company, or reveal the cash an owner will receive after a transaction. Capital expenditures, working capital, financing arrangements, taxes, debt, transaction structure and other factors can materially affect the result.

If the business is owner-operated and you want to understand the economic benefit available to one working owner, compare EBITDA with Seller’s Discretionary Earnings (SDE). Our SDE vs. EBITDA guide explains the distinction. Owners can also use the Owner’s Cash Flow Calculators to organize relevant cash-flow information; those tools do not by themselves calculate a verified EBITDA figure or provide a formal valuation.

Using EBITDA in a business valuation

After the calculation has been checked and any adjustments have been assessed, EBITDA may be used as one input in an EBITDA-based valuation. A simplified formula is:

Illustrative enterprise value = normalized EBITDA × selected EBITDA multiple

The multiplication is only as reliable as its inputs. The selected multiple should be considered separately using relevant market evidence and business-specific factors. See EBITDA Multiples for that analysis. Enterprise value also differs from equity value and seller net proceeds; debt, cash, working capital, fees, taxes and transaction terms may affect what the owner ultimately receives.

For a broader overview of business value and the factors that can influence it, see Business Valuation in New York, How Much Is My Business Worth? and the Business Valuation Calculator Guide. An online tool can help organize assumptions or illustrate an estimate; it cannot verify financial records or guarantee a transaction price.

Calculating EBITDA for businesses in New York

The EBITDA formula itself does not change because a business operates in New York City, Long Island, Westchester County or the Hudson Valley. What changes is the operating context behind the figures and the questions that may deserve attention. For example, a professional-services firm may need to explain staffing and client relationships; a contractor may need to document project margins, vehicles and equipment; and a distributor may need to clarify inventory, facilities, supplier terms and working capital. These examples are prompts for reviewing the company’s records, not assumptions about every business in a location.
