What is EBITDA?

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortisation. It’s a key financial metric that shows how much profit a company makes from its core operations, before factoring in costs that don’t directly relate to running the business day-to-day.

In simple terms, EBITDA tells you how well a company performs at its primary job (selling its products or services) without the effects of financing, taxes, or accounting adjustments. That’s why investors and founders often use it to compare operating performance, while remembering that EBITDA is not the same as cash flow.

It cuts through some financial noise to show operating earnings before selected costs. It is useful for assessing business efficiency, but it should be read alongside profit, cash flow, working capital, and capital expenditure.

EBITDA: Components

Let’s look at what each part of the acronym means to grasp the concept of EBITDA. The following five components are either added back or used as a starting point to show how much profit comes purely from the company’s core operations:

• Earnings (Net Income): this is your company’s bottom line. After subtracting all expenses, including operating costs, interest, taxes, and depreciation or amortisation, it shows the total money earned from selling products or services. It’s the base from which EBITDA starts.
• Interest: this is the cost of borrowing money, such as bank loans or credit lines. It’s added back because financing choices differ from one company to another and don’t reflect how efficiently a business actually runs.
• Taxes: these are payments made to the government based on your company’s income. They’re excluded because tax rates vary by country and policy, making it hard to compare performance between businesses fairly.
• Depreciation (D): this non-cash expense shows how physical assets, like machines, vehicles, or equipment, lose value over time. It’s added back since no actual money leaves the business when this is recorded.
• Amortisation (A): similar to depreciation, this non-cash expense applies to intangible assets like patents, trademarks, or software. It’s also added back to show the company’s true cash-generating power.

This breakdown highlights why investors use EBITDA. It shows operating earnings before financing, tax, depreciation, and amortisation, but it does not prove that the business has the same amount of cash available to spend.

How to Calculate EBITDA

Know that there are two primary formulas when learning how to calculate EBITDA. Both yield the same result and provide a clear view of operational earnings. The choice depends on which figures are most readily available on your Income Statement.

Formula 1: Starting with Net Income (The “Bottom-Up” Method)

This is the most common approach, especially when working backwards from the company’s final reported profit: the bottom line. You begin with Net Income and then add the four items excluded from EBITDA: interest, taxes, depreciation, and amortisation.

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

Formula 2: Starting with Operating Income (The “Top-Down” Method)

This method simplifies the calculation since Operating Income, also known as EBIT (Earnings Before Interest and Taxes), already excludes interest and tax expenses. From there, you simply add Depreciation and Amortisation back to EBITDA.

EBITDA = Operating Income (EBIT) + Depreciation + Amortisation

What is EBITDA margin?

EBITDA margin puts the EBITDA figure in context by showing it as a percentage of revenue. The formula is:

EBITDA margin = (EBITDA / Revenue) x 100¹

For example, a business with £65,000 of EBITDA and £250,000 of revenue has an EBITDA margin of 26%. A higher margin is not automatically better: compare it with similar businesses, the company's own history, and the level of investment needed to maintain its operations.

EBITDA vs EBIT and net income

These measures answer different questions:

EBITDA can make comparisons easier when businesses have different financing or asset profiles. EBIT may give a more realistic view where depreciation reflects a significant, recurring cost, while net income shows the bottom-line result. Use the measure that matches the decision you are making.

Startup Example: Comparing Two Businesses

EBITDA is especially useful for fast-growing UK startups still heavily investing in their operations. It allows investors to compare companies on an “apples-to-apples” basis, regardless of differences in debt levels, tax structures, or capital investments.

For example, imagine two UK SaaS startups, Alpha and Beta.

The EBITDA Calculation

We’ll use the first formula: Net Income + Interest + Taxes + Depreciation + Amortisation.

At first glance, Startup Alpha’s £50,000 net loss looks bad. But, after adding back non-operational costs like depreciation, amortisation, and interest, its EBITDA turns positive at £35,000. The loss mainly comes from heavy investments and debt costs.

Startup Beta shows a £25,000 net profit and an even stronger EBITDA of £45,000.

This comparison shows that Beta’s core operations are performing better than Alpha’s, regardless of Alpha’s spending on new assets or debt. This insight really matters when judging a startup’s actual value and funding potential.

Uses and Applications of EBITDA

EBITDA is a critical non-GAAP (or non-IFRS) financial metric widely used in corporate finance, investment, and accounting. A few use cases of it are:

Evaluating Company Performance

EBITDA is frequently used as an indicator of operating performance, but it is not a cash-flow statement or a substitute for operating cash flow.

Core Profitability: EBITDA adds back non-cash expenses like depreciation and amortisation to show a company’s true operating profit. It helps reveal how much the business actually earns from its core activities before major investments.

Management Focus: Companies use EBITDA targets to track efficiency and motivate teams. This is because it reflects results they can directly control through sales and cost management.

Comparing Companies in the Same Industry

One of EBITDA’s greatest strengths is its ability to standardize financial comparisons across companies, a process known as “normalization.” It removes factors like interest (debt costs), taxes (which vary by country), and accounting methods for depreciation. This helps you compare businesses with different debt levels, tax systems, or reporting standards, giving a clearer picture of true performance.

Debt Servicing Capacity

Lenders and banks closely watch a company’s EBITDA because it shows how easily it can repay its debts.

Since EBITDA excludes interest, it can be one input into debt analysis, including a debt-to-EBITDA ratio. Lenders also need to consider actual cash flow, working capital, repayment terms, and the assets supporting the business.

For example, a UK lender might look for a company whose total debt is only two to three times its annual EBITDA. So, a lower ratio means the business can pay off debt faster and poses less risk.

Valuation Multiples

EBITDA is key in valuing companies, especially during mergers, acquisitions, and private equity deals.

The Enterprise Value to EBITDA (EV/EBITDA) multiple is a widely used method². This compares a company’s total value (including debt and equity) to its EBITDA. This helps estimate a fair value by comparing it to similar public or recently acquired companies.

In capital-heavy industries like telecom, manufacturing, and energy, EV/EBITDA may be preferred over the Price-to-Earnings (P/E) ratio because it removes some distortions caused by different depreciation methods or debt levels².

That’s why credit officers in London and even global M&A teams rely on EBITDA as their go-to metric for comparable financial insight.

Why is EBITDA important for startups?

EBITDA can be useful for startups because it shows an operating result before selected financing, tax, and asset charges. New companies often have low or negative Net Income due to high initial investment costs and non-cash expenses, but a positive EBITDA does not by itself mean the startup is profitable or cash-generative.

Simplifies Company Comparison

It helps to look past the individual financial choices of a startup and focus on its business model.

• Ignores financing and tax: startups often take out large initial loans or receive special tax breaks. EBITDA ignores Interest and Taxes, making it easier for investors to compare the operating performance of one startup to another, regardless of their unique debt or tax structures.
• Levels the playing field: if you’re a potential buyer looking at two similar software startups, one with no debt and one with a large bank loan, EBITDA lets you compare them based only on how well they sell software, not their loan payments.

Highlights Operational Profitability

It gives a clear vision of the operational success of a startup before accounting rules take their toll.

• Focus on core business: most startups spend a lot of money in their early years on machinery, equipment, or building a brand (intangible assets). Accounting rules require them to spread the cost of these assets over many years as Depreciation and Amortisation (D&A), which drives Net Income down.
• Shows potential: by adding back D&A, EBITDA highlights operating earnings, showing that a startup can have a positive operating result even if it reports a loss on paper. It is not a measure of cash available to spend.

Useful for Capital-Intensive Industries

EBITDA is often the primary measure of success for startups in sectors that require heavy initial asset spending.

• High upfront costs: companies building a factory, a logistics network, or a massive data center (all standard startup models) have huge D&A expenses. Traditional accounting would make these companies look unprofitable for years.
• Investment context: EBITDA gives potential investors or acquirers another view of operating performance, but it does not by itself prove that a large initial investment has produced recurring profits.
• Valuation: in these sectors, buyers will almost always value the company using a multiple of its EBITDA, not its Net Income. It makes the EBITDA number critical for setting the startup’s price.

The importance of EBITDA for startups lies in how it helps investors and lenders assess operating performance. It can inform valuation and lending discussions, but it does not by itself show how easily a startup can repay its debts.

Limitations of EBITDA

EBITDA is a useful tool, but it is often criticised because it ignores essential business costs. It is a non-GAAP or non-IFRS measure rather than a complete accounting measure of profit, and different businesses may calculate adjusted versions differently.³

A few limitations of EBITDA could be:

• Ignores CapEx: hides costs of maintaining assets, risking future collapse.
• Excludes financing costs: masks the burden of debt payments.
• Ignores taxes: overstates true cash available after HMRC payments.
• Not a cash flow proxy: omits CapEx and working capital changes, misrepresenting liquidity.
• Easily manipulated: companies can inflate EBITDA by reclassifying expenses.

EBITDA is a quick way to view a business’s operating earnings without the effects of taxes, debt, or depreciation and amortisation. For UK startups, it can help investors and lenders assess performance even when early spending keeps the business in the red. Use it alongside net profit, operating cash flow, free cash flow, working capital, and capital expenditure.
