EBITDA calculation formula and how to distinguish it from EBIT.

The EBITDA formula is considered an important indicator to evaluate core operating efficiency, eliminating the impact of interest expenses and depreciation. According to international standards, the EBITDA formula is calculated as follows:

• From operating profit (EBIT):

In which EBIT:

• Profit before tax:

• Profit after tax:

This index not only helps managers understand the profitability of core activities, but is also a measure that investors and credit institutions often use when comparing businesses in the same industry.

What is EBITDA? 

EBITDA is an important financial indicator that reflects the ability of a business to generate profits from its core business activities, without taking into account financial or accounting factors such as corporate income tax, interest expense, depreciation and asset allocation. By eliminating these factors, EBITDA allows managers and investors to focus on evaluating the actual operating results and profitability of the business's core activities, instead of being influenced by tax policy or capital structure.

EBITDA is an acronym for Earnings Before Interest, Taxes, Depreciation and Amortization, which means earnings before interest, taxes, depreciation of tangible and intangible assets. Specifically: 

• Earnings Before Interest: Is the profit of an enterprise determined before deducting interest expenses arising from financial debts.
• Taxes: The amount of money a business must pay to the tax authorities.
• Depreciation: is the loss of value of tangible fixed assets (such as factories, machinery, equipment, etc.) over time, reflecting wear and tear.
• Amortization: The net decrease in value of intangible assets such as patents and trademarks over time..

In financial reporting, the EBITDA calculation formula is considered a crucial measure for evaluating a company's core operational performance. This indicator allows investors and managers to analyze the company's ability to generate actual profits without being influenced by financial factors such as interest expenses, taxes, or depreciation. Applying the correct formula not only helps businesses focus on profits from their core operations but also provides a basis for more objective comparison and evaluation of business performance among companies in the market.

The role of EBITDA in financial analysis

The EBITDA calculation formula is one of the most widely used indicators in financial analysis because it focuses on net business performance and eliminates the influence of capital structure, depreciation policies, and taxes. The table below will explain in detail the practical role of the formula:

Thus, as shown in the table above, the role of the EBITDA calculation formula is not just a simple calculation, but also a financial tool that helps businesses, investors, and credit institutions accurately assess operational efficiency. When applied correctly and combined with other supporting indicators, this formula becomes an important foundation in the management, valuation, and sustainable development strategies of businesses.

Formula for calculating EBITDA most accurate

To calculate accurately, businesses can immediately apply the international standard EBITDA calculation formula below:

• From operating profit EBIT

In which EBIT:

• Profit before tax

• Profit after tax

For example: Suppose that in the fiscal year, enterprise A has information such as pre-tax accounting profit of 50 billion, interest expense of 100 billion and depreciation of 30 billion.

Apply formula number 2:

Therefore, based on the calculation formula, the EBITDA of company A is 180 billion VND. 

EBIT of enterprise A: 

Thus, EBIT of enterprise A is 150 billion VND.

The significance of calculating EBITDA in measuring business performance. 

Besides understanding what EBITDA is, managers and investors also need to master its calculation method to apply it effectively in financial analysis. This is one of the important indicators reflecting the core operational efficiency of a business, helping to eliminate the impact of interest expenses, taxes, and depreciation costs. Therefore, EBITDA shows the true business performance, supporting businesses, owners, and investors in gaining a more accurate view of production and business efficiency as well as sustainable long-term profitability.

For business owners

Mastering the formula not only helps businesses understand the nature of this indicator but also provides a foundation for maximizing its value in financial analysis and management. Specifically:

• Assessing a business's profitability: By eliminating factors such as interest, taxes and depreciation, EBITDA more accurately reflects the efficiency of generating profits from core production and business activities.
• Compare performance over time: Because it is not affected by fluctuations in interest rates or tax rates, business owners can easily track and compare growth over each period.
• Convincing investors: When presenting reports, EBITDA is a powerful indicator that helps businesses convey a positive picture of financial health and operating capacity, thereby increasing investor confidence.

For investors 

To maximize the value from the EBITDA calculation formula, investors and managers often apply this index in many important aspects of business analysis:

• Assessing cash flow generation: EBITDA is a useful tool to determine the profitability of core operations, thereby considering the ability to quickly pay back capital and long-term growth potential.
• Comparing companies within the same industry: By removing the impact of taxes and interest, EBITDA makes comparing performance between companies more transparent and objective.
• Estimating Enterprise Value: Popular valuation metrics such as EV/EBITDA are often used to determine fair value, helping investors identify whether a business is overvalued or undervalued relative to its intrinsic value.

Although commonly used in financial analysis, many people still easily confuse EBITDA and EBIT because both indicators reflect profits from business operations. However, to understand the true nature and avoid inaccuracies in evaluating business performance, it is necessary to clearly distinguish between EBIT and EBITDA.

Distinguishing features of EBIT and EBITDA

Once you understand the concept of EBITDA and the detailed formula, differentiating between EBITDA and EBIT becomes simpler. Although these two indicators have many similarities, they are often compared to comprehensively assess a company's performance. The table below illustrates the differences between these two indicators:

From the comparison table above, it can be seen that both EBIT and EBITDA are important metrics for analyzing corporate finance, but each serves a different purpose. While EBIT focuses on profit before interest and taxes, EBITDA reflects core operating performance by excluding depreciation. Understanding this difference helps managers and investors apply the correct metric in each situation, thereby making more accurate decisions.

So why is EBITDA considered an accurate measure of business performance?

Because EBITDA excludes factors not directly related to core business operations, such as interest expense, corporate income tax, or depreciation expense. These factors may vary depending on financial policies, capital structure, or legal regulations in each country, but they do not reflect the true nature of a company's operational capabilities.

Focusing solely on the results generated from core business operations helps managers and investors clearly see the true effectiveness of revenue generation. For example, two companies in the same industry may differ in debt ratios or depreciation policies, leading to differences in net profit. However, comparing them using EBITDA will reveal which company operates more efficiently, regardless of differences in capital or financial strategies.

In other words, EBITDA is a "fair measure" for evaluating business performance, helping to eliminate distortions from external factors and providing a more honest view of the internal operational strength of the business.

Cases where the EBITDA calculation formula is applied

The EBITDA calculation formula is widely used in many situations to analyze and evaluate the financial performance of businesses. Particularly in industries with a high proportion of assets and high depreciation costs, the formula is often used to reflect operating profit, helping businesses improve their financial reporting image and increase investor confidence.

Furthermore, it is an important tool for comparing the performance of businesses within the same industry or at different stages of development. This indicator often appears in EV/EBITDA valuation models and in many cases can replace cash flow in quick analysis.

Furthermore, investors and managers also utilize the formula through derived indicators such as EBITDA Margin, EBITDA/Depreciation Expense, or Debt/EBITDA, to assess the profitability, level of financial leverage, and long-term growth prospects of the business.

Advantages and disadvantages of the formula

We need to consider both the advantages and disadvantages of the formula. Like any measurement tool, the formula offers significant benefits but also has certain limitations. The table below will help distinguish the advantages and disadvantages of the EBITDA calculation formula, thereby assisting investors and businesses in using this indicator more accurately.

The EBITDA calculation formula is a useful tool for measuring business performance and comparing different companies. However, when conducting financial analysis, it is necessary to combine EBITDA calculation with net profit and cash flow to gain a comprehensive view and minimize the risk of misvaluation.

Notes when applying the EBITDA calculation formula in business and investment

When applying the EBITDA calculation formula, businesses need to keep the following points in mind to ensure that the EBITDA results are effective: 

• Understanding the EBITDA metric, its formula, and its meaning is crucial: EBITDA only reflects profit before accounting for factors such as interest, taxes, depreciation, and amortization. This allows businesses to focus on evaluating core operating performance, but the formula for this metric doesn't provide a comprehensive view of net profit after deducting significant financial expenses.
• Combined with other index formula analysis: The EBITDA formula is just one of many formulas to help evaluate finances. Businesses need to refer to using additional index formulas such as ROE (Return on Equity), ROA (Return on Assets) and free cash flow to help provide a more complete perspective on business performance.
• Assessing the scale, industry characteristics and business cycle: Due to the characteristics of each industry with different investment levels and depreciation costs, the use of the EBITDA calculation formula needs to be placed in the specific context of the industry and business cycle, to ensure accurate comparison between businesses in the same industry.
• Be careful when making decisions: To attract investors, some businesses may "beautify" their reports by increasing the EBITDA index. Therefore, managers need to carefully evaluate the data to avoid being led by numbers that do not reflect reality.

Reference: Interest expenses are not deductible under Decree 255/2026.

Conclude

In summary, the EBITDA formula is a useful tool for businesses and investors to evaluate core operating performance, eliminating financial and accounting factors that interfere. However, for a more comprehensive and accurate view, EBITDA needs to be placed in the context of the industry, business cycle and combined with other financial indicators.

Frequently Asked Questions about the EBITDA Calculation Formula

What does negative EBITDA mean?

Negative EBITDA means the business is losing money at the core operating level, even before accounting for interest, taxes, and depreciation. This is a much more serious warning sign than negative net profit, because negative net profit may simply be due to high interest or depreciation expenses, while negative EBITDA indicates that the business itself is not generating cash.

What is a good EBITDA level? What is the ideal EBITDA margin?

There is no single standard EBITDA margin (EBITDA/Revenue) for all industries. Manufacturing, telecommunications, and real estate typically have margins of 20-40% (TP3T) due to capital intensity; trade and retail industries usually have margins of only 5-15% (TP3T) due to thin profit margins. The correct way to assess EBITDA is to compare a company's EBITDA margin with the industry average and with the company itself over different periods, not cross-industry comparisons.

Does EBITDA include corporate income tax?

No. EBITDA is calculated before deducting corporate income tax. If you start calculating from after-tax profit, you must add back the corporate income tax already paid along with interest expense and depreciation to arrive at the correct EBITDA figure.

What EV/EBITDA ratio is considered reasonable?

A reasonable EV/EBITDA ratio depends on the industry and growth stage: high-growth sectors (technology) are typically valued at 12-20 times, while traditional sectors (manufacturing, trading) are commonly valued at 6-10 times. A lower-than-average EV/EBITDA ratio may indicate an attractive valuation, but it could also reflect underlying risks not yet recognized by the market, requiring further analysis in relation to revenue growth and debt leverage.
