Earnings Before Interest, Taxes, Depreciation & Amortisation
EBITDA
EBITDA measures a company's operating profitability by stripping out financing decisions, tax strategies, and non-cash accounting entries. It is one of the most widely used metrics for comparing the operational performance of businesses across industries.

What is EBITDA?
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortisation. It measures profit from a company's core operations. It strips out capital structure (interest), tax region (taxes), and non-cash charges (depreciation and amortisation).
Stripping out these items isolates how well the business runs day to day. Two companies with the same operations but different debt levels will show different net income due to interest. Two companies in different countries face different tax burdens. Two companies that made large buys in different years carry different amortisation schedules. EBITDA removes these gaps to give a like-for-like view of operating results.
EBITDA has become the standard profit metric for private equity, M&A, and SaaS valuations. Enterprise values are often shown as a multiple of EBITDA (EV/EBITDA). This makes it the yardstick by which companies are priced. For SaaS companies, EBITDA margin feeds into the Rule of 40. There it combines with growth rate to gauge overall financial health.
EBITDA is not a GAAP or IFRS measure. It is a non-standard metric that companies can calculate in slightly different ways. Always check the specific adjustments a company makes when comparing EBITDA figures across businesses.
How to calculate EBITDA
There are two common ways to calculate EBITDA:
Bottom-up method (start from net income):
EBITDA = Net Income + Interest Expense + Tax Expense + Depreciation + Amortisation
Top-down method (start from revenue):
EBITDA = Revenue - Cost of Goods Sold - Operating Expenses (excluding D&A)
Or equivalently:
EBITDA = Operating Income (EBIT) + Depreciation + Amortisation
Both methods should give the same result. The top-down method is often easier because operating income is usually a reported line item. You simply add back D&A.
EBITDA margin shows EBITDA as a share of revenue:
EBITDA Margin = EBITDA / Revenue x 100
This figure is more useful for comparison because it adjusts for company size. A company with 5M EBITDA on 50M revenue (10% margin) runs less efficiently than one with 3M EBITDA on 15M revenue (20% margin).
| Variant | Definition | Use case |
|---|---|---|
| EBITDA | Standard calculation with no adjustments | General performance comparison, valuation multiples |
| Adjusted EBITDA | EBITDA with one-time and non-recurring items removed | M&A transactions, recurring earnings assessment |
| EBITDA margin | EBITDA as a percentage of revenue | Operational efficiency comparison across different-sized companies |
EBITDA in a metric tree
An EBITDA metric tree breaks operating profit into its revenue and cost parts. It traces each back to the business functions and choices that drive it. This turns EBITDA from a finance report into a hands-on management tool.
The tree shows three paths to better EBITDA: grow revenue, improve gross margin (cut COGS), or build operating leverage (grow revenue faster than expenses). Each path ties to different teams and different spending choices.
For SaaS companies, the operating expense split matters most. Sales and marketing often takes 30-50% of revenue at the growth stage. R&D takes 20-30%. G&A takes 10-15%. Knowing these ratios and how they shift with scale is key to EBITDA planning.
EBITDA margin benchmarks
| Industry | Typical EBITDA margin | Key factors |
|---|---|---|
| SaaS (growth stage) | -20% to 0% | Heavy investment in growth. Negative margins are accepted if growth rate is high (Rule of 40). |
| SaaS (mature) | 20-35% | Operating leverage realised at scale. Best-in-class companies reach 35%+ margins. |
| Professional services | 15-25% | People-intensive with limited scale economies. Margins constrained by utilisation rates. |
| Manufacturing | 10-20% | Capital-intensive with significant COGS. Margins driven by volume and production efficiency. |
| Retail | 5-10% | Low margins offset by high volume. EBITDA very sensitive to same-store sales changes. |
For SaaS companies, the long-term EBITDA margin target is typically 25-35% at scale. This is the structural margin the model can reach once growth spending levels off. The path runs through better gross margin (scaling infrastructure costs slower than revenue) and operating margin leverage (growing revenue faster than headcount).
How to improve EBITDA
Grow revenue
Revenue growth is the strongest EBITDA lever because many costs are semi-fixed. Doubling revenue does not mean doubling the finance team or office space. This built-in leverage lifts EBITDA margin on its own.
Improve gross margin
Cut COGS through better infrastructure, support automation, and stronger vendor deals. Each percentage point of gross margin gain flows straight to EBITDA.
Control headcount growth
People costs are the biggest expense for most companies. Raising revenue per employee through automation, process gains, and careful hiring lifts EBITDA margin without cutting investment.
Reduce customer acquisition costs
A more efficient go-to-market shrinks the sales and marketing line. Product-led growth, organic channels, and better conversion rates all cut S&M as a share of revenue.
Common mistakes
- 1
Treating EBITDA as cash flow
EBITDA leaves out working capital changes, capital spending, and debt payments. A company with strong EBITDA can still burn cash if it has high capex or working capital needs. Use free cash flow for cash analysis.
- 2
Excessive adjusted EBITDA adjustments
Some companies strip out stock-based pay, restructuring costs, and other items that come back often. If these adjustments happen every quarter, they are not truly one-off.
- 3
Ignoring capital intensity differences
A software company and a manufacturer may post similar EBITDA margins. But the manufacturer needs far more capital spending to keep running. EBITDA does not capture this gap.
Related metrics
Operating Margin
Core business profitability
Financial MetricsMetric Definition
Operating Margin = (Operating Income / Revenue) x 100
Operating margin measures the percentage of revenue that remains after paying for both cost of goods sold and operating expenses. It isolates the profitability of core business operations, excluding the effects of financing decisions and tax strategies.
Net Profit Margin
Bottom-line profitability
Financial MetricsMetric Definition
Net Profit Margin = (Net Income / Revenue) x 100
Net profit margin measures the percentage of revenue that remains as profit after all expenses, including cost of goods sold, operating expenses, interest, and taxes. It is the ultimate measure of a company's ability to convert revenue into profit.
Free Cash Flow
FCF
Financial MetricsMetric Definition
FCF = Operating Cash Flow - Capital Expenditures
Free cash flow (FCF) measures the cash a business generates from operations after accounting for capital expenditures. It represents the actual cash available to pay dividends, repay debt, fund acquisitions, or invest in growth.
Rule of 40
Growth + Profit benchmark
SaaS MetricsMetric Definition
Rule of 40 Score = Revenue Growth Rate (%) + Profit Margin (%)
The Rule of 40 states that a healthy SaaS company's combined revenue growth rate and profit margin should equal or exceed 40%. It balances the tension between growth and profitability, providing a single benchmark for overall business health.
Decompose EBITDA into actionable levers
Build a metric tree that connects EBITDA to revenue growth, gross margin, and operating expense efficiency so every team can see how their work contributes to profitability.
