EBITDA vs Net Profit: Which Number Actually Matters?

What EBITDA stands for

Earnings Before Interest, Tax, Depreciation and Amortisation. It's net profit with four items added back. Each addback exists for a reason — together they describe how operationally profitable the business is, independent of how it's financed, where it operates, and what assets it owns.

The four addbacks explained

• Interest. Different businesses fund themselves differently — debt vs equity. Adding interest back makes a leveraged business comparable to a debt-free one.
• Tax. Tax rates differ across jurisdictions (21% US corporate, 25% UK, 27% SA). Stripping tax compares operational profit before any geography effect.
• Depreciation. A non-cash charge that spreads the cost of physical assets over their life. The cash already went out years ago when the asset was bought.
• Amortisation. Same idea for intangible assets (goodwill, software, IP). Non-cash, historical.

A worked example

A manufacturer's income statement:

Same business: $400k EBITDA, $213k net profit. A buyer might value this at 5× EBITDA ($2M) or 9× net profit ($1.9M) — similar valuations but different conversations.

Where EBITDA matters most

• Selling your business. Almost all SME transactions are quoted as a multiple of EBITDA (3–7× typical).
• Comparing businesses across industries or geographies. Strips out tax and financing structure.
• Lender debt-service coverage ratios. Banks use EBITDA-to-debt-service as a primary loan covenant.
• Private equity returns. Returns are usually expressed as EBITDA growth multiples.

Where EBITDA misleads

• Capital-intensive businesses. Depreciation isn't fake — those trucks/machines/buildings genuinely wear out and need replacing. EBITDA flatters businesses that need constant capex.
• Highly leveraged businesses. Stripping interest hides the real burden of debt. Two businesses with the same EBITDA can have wildly different net profit if one has 5× the debt.
• Tech with heavy stock-based comp. "Adjusted EBITDA" sometimes strips out share-based payments that are real economic costs.

When net profit is the right number

• Tax filings. Tax is paid on taxable income, not EBITDA.
• Distributions to owners. You can only distribute what's left after tax — net profit.
• Personal income for sole traders. Net profit IS your income, broadly.
• Long-term sustainability check. If net profit is negative for years, the business isn't viable regardless of EBITDA.

Bottom line

• EBITDA = net profit + interest + tax + depreciation + amortisation.
• Used for valuation, lending, and cross-comparison.
• Net profit is the real bottom line for tax and distributions.
• EBITDA flatters capital-intensive and leveraged businesses — always check what's being added back.
