EBITDA
イービットディーエー
EBITDA means earnings before interest, taxes, depreciation, and amortization. It helps compare operating earnings before capital structure, tax, and non-cash depreciation or amortization effects, but it is not cash flow or GAAP net income.
EBITDA is a non-GAAP operating performance measure that starts from earnings and adds back interest, taxes, depreciation, and amortization. Teams use it when they need a normalized view of operating profit across companies, business units, or acquisition targets. Its value comes from comparability; its risk is that it can hide capital intensity, working-capital needs, financing cost, tax exposure, and aggressive adjustment policy.
Use one calculation policy consistently and reconcile it to the closest financial statement line. Net income method | EBITDA = net income + interest expense + income taxes + depreciation + amortization | Use when starting from the bottom line Operating income method | EBITDA = operating income + depreciation + amortization | Use when the review focuses on operating performance Adjusted EBITDA | EBITDA +/- documented non-recurring adjustments | Use only with a written adjustment policy and reconciliation
| Lens | Formula / treatment | When to use it |
|---|---|---|
| Net income method | EBITDA = net income + interest expense + income taxes + depreciation + amortization | Use when starting from the bottom line |
| Operating income method | EBITDA = operating income + depreciation + amortization | Use when the review focuses on operating performance |
| Adjusted EBITDA | EBITDA +/- documented non-recurring adjustments | Use only with a written adjustment policy and reconciliation |
EBITDA is useful only when the team writes what is included and what is intentionally excluded. Include | Earnings, interest, taxes, depreciation, and amortization from the same period and entity boundary | Keeps the numerator auditable Exclude | Capex, working-capital movement, debt principal payments, cash taxes paid timing, and one-time revenue | These are not captured by basic EBITDA Define explicitly | Stock-based compensation, restructuring costs, acquisition expenses, lease treatment, and owner compensation | Adjustment choices can change the conclusion

EBITDA moves when operating profit, cost structure, accounting policy, or adjustment policy changes. Revenue quality | Price, volume, mix, renewals, and non-recurring revenue | Separates durable operating growth from temporary uplift Cost structure | Gross margin, headcount, support cost, and operating leverage | Explains whether EBITDA improvement is scalable Adjustment policy | Add-backs, one-time costs, and accounting choices | Shows whether the number is comparable or overstated

Use EBITDA to compare operating performance when capital structure or tax position differs across companies. Use EBITDA in valuation only after checking revenue durability, capex needs, working-capital movement, and debt service. Use EBITDA in management reviews when the adjustment policy is stable enough for quarter-over-quarter comparison.

- Use EBITDA in valuation only after checking revenue durability, capex needs, working-capital movement, and debt service.
- Use EBITDA in management reviews when the adjustment policy is stable enough for quarter-over-quarter comparison.
- EBITDA is a comparability tool, not a complete profitability or liquidity answer.
- A higher EBITDA number can still be weak if capex, working capital, churn, or debt burden is high.
- Adjusted EBITDA needs a reconciliation and a stable policy; otherwise add-backs can become storytelling.
- Read EBITDA with EBITDA margin, free cash flow, net income, revenue growth, and leverage.
- Keep the same period, entity boundary, and adjustment rules when comparing companies or quarters.
Do not make capital allocation, acquisition, or financing decisions from EBITDA alone. Check whether the number is GAAP, non-GAAP, adjusted, or management-defined. Reconcile EBITDA to net income or operating income before using it externally. For public-company style disclosure, keep non-GAAP presentation and reconciliation rules in view.

EBITDA should be read with metrics that explain scale, margin quality, liquidity, and risk. EBITDA Margin | EBITDA / revenue | Shows operating profit intensity Free Cash Flow | Cash after operating needs and capex | Tests whether EBITDA converts into cash Net Income | GAAP bottom-line profit | Keeps the analysis tied to complete earnings Leverage Ratio | Debt / EBITDA | Tests debt capacity and lender risk
| Metric | Role | Why read together |
|---|---|---|
| EBITDA Margin | EBITDA / revenue | Shows operating profit intensity |
| Free Cash Flow | Cash after operating needs and capex | Tests whether EBITDA converts into cash |
| Net Income | GAAP bottom-line profit | Keeps the analysis tied to complete earnings |
| Leverage Ratio | Debt / EBITDA | Tests debt capacity and lender risk |
A software acquirer compares two targets. Target A has $10M revenue, $1.6M net income, $300k interest, $400k tax expense, $700k depreciation, and $200k amortization, so EBITDA is $3.2M. Target B has $3.5M EBITDA but needs $1.4M annual capex and has weaker retention. The team uses EBITDA for operating comparability, then lowers Target B's valuation after checking free cash flow, churn, and debt capacity.
EBITDA | Profit before interest, taxes, depreciation, and amortization | Useful for operating comparability EBIT | Profit before interest and taxes | Keeps depreciation and amortization inside operating performance Operating Income | GAAP operating result before non-operating items | Better for financial statement discipline Free Cash Flow | Cash left after operations and investment needs | Better for liquidity and owner cash Adjusted EBITDA | EBITDA after management-defined add-backs | Better only when adjustments are documented and comparable

- EBITDA is not cash flow; it excludes capex, working capital, debt principal, and timing of cash taxes.
- EBITDA is not the same as net income; it removes real costs that still matter to owners and lenders.
- Adjusted EBITDA is not automatically better; the adjustment policy can make weak performance look stronger.
- A company with positive EBITDA can still need financing if growth consumes working capital or capex.
Is EBITDA a GAAP measure?
No. EBITDA is commonly used as a non-GAAP performance measure, so it should be reconciled to the closest GAAP measure when used in formal reporting contexts.
Why do investors use EBITDA?
It helps compare operating earnings before financing structure, tax position, and depreciation or amortization policy, especially in valuation and acquisition screens.
What is the biggest risk of EBITDA?
It can overstate business health when a company has high capex, working-capital needs, debt burden, or aggressive add-backs.
When should I use EBITDA margin instead?
Use EBITDA margin when you need to compare EBITDA relative to revenue, not just the absolute EBITDA amount.
