What this result does not account for
- Ignores capital expenditure entirely, which makes it unreliable for asset-heavy businesses.
- Excludes working capital movements, so a growing business can show strong EBITDA while consuming cash.
- Adjusted EBITDA is not a defined accounting measure and its add-backs are frequently contested in diligence.
In short: Adding $96,000 of D&A to $372,000 of EBIT gives $468,000 of EBITDA, a 19.50% margin against a 15.50% operating margin. But capex of $140,000 exceeds D&A by $44,000, so EBITDA overstates the cash the business actually produces.
Formula
EBITDA adds back a non-cash charge that exists precisely because assets wear out. Subtracting real capex is the only honest way to test whether the add-back is justified.
Worked Example
- Start from operating income. $372,000 of EBIT, a 15.50% operating margin. This figure already carries the depreciation charge.
- Add back the non-cash charges. $96,000 of depreciation and amortisation gives $468,000 of EBITDA — a 19.50% margin, exactly 4.00 points above the operating margin.
- Test it against real capex. $140,000 of capital expenditure exceeds the $96,000 charge by $44,000. The assets cost more to replace than the accounts are recognising.
- Compute the honest cash proxy. $468,000 less $140,000 of capex is $328,000, or 13.67% of revenue — below the operating margin, not above it.
- Bridge to valuation. At 5.5×, enterprise value is $2,574,000. At the 7.6× that businesses above 80% gross margin command, it is $3,556,800 — a $982,800 difference on identical earnings.
EBITDA earns its criticism precisely in cases like this one. The metric adds back $96,000 of depreciation on the theory that it is a non-cash accounting artefact, yet the business spent $140,000 of actual cash on capital equipment in the same period. The depreciation was not a fiction; it was an understatement. A buyer paying 5.5× on $468,000 of EBITDA is paying $2,574,000 for a business that generated $328,000 of cash before interest and tax, an effective 7.85× on the honest figure. This is why quality-of-earnings work always reconciles EBITDA to cash before a deal closes.
Strengths & Limits Of This Model
Where this engine is strong
- Reports EBITDA less capex alongside the headline, exposing when the add-back is unjustified.
- Bridges directly to enterprise value across a range of multiples.
- Tests capex against D&A to show whether the asset base is being maintained.
Where it stops
- Cannot substitute for a genuine cash flow statement.
- Industry multiple ranges are wide, so the valuation output is indicative only.
Practical Use Cases
Preparing a business for sale
EBITDA is the number a buyer starts from. Test what it implies across a range of multiples with the EBITDA Multiple Calculator.
Comparing capital-intensive businesses
EBITDA neutralises differing depreciation policies, which is exactly why it is used to compare companies with different asset ages and accounting choices.
Testing lender covenants
Most debt covenants are written against EBITDA. Check headroom with the Debt Service Coverage Ratio Calculator.

Methodology & Editorial Standards
EBITDA margin divides earnings before interest, tax, depreciation and amortisation by revenue. Its purpose is comparability: by removing financing decisions, tax jurisdiction and depreciation policy it allows businesses with different capital structures and asset ages to be compared on operating performance, which is why it dominates mid-market M&A and lender covenants. Its well-documented weakness is that depreciation is not a fiction — it represents assets genuinely being consumed — so the engine requires capital expenditure as an input and reports EBITDA less capex alongside the headline margin. Where capex exceeds the depreciation charge, EBITDA overstates sustainable cash generation, and where it falls materially below, the business is deferring investment in a way that cannot continue indefinitely. Benchmarks verified for 2026 place SaaS and software at 20% to 40% with deep-tech and infrastructure reaching 35% to 50%, professional services at 15% to 25%, home services at 10% to 20%, manufacturing at 8% to 18%, restaurants at 8% to 15%, retail at 4% to 10% and distribution at 3% to 8%. On valuation, businesses with gross margins above 80% earn a median multiple of 7.6 times against 5.5 times below that threshold, and margin trend is weighted more heavily than absolute level: a business improving from 8% to 14% over three years typically prices better than one flat at 18%. The engine implements the standard published formula for this calculation. Inputs are validated for domain and sign before evaluation, and any undefined case returns an em-dash rather than a spurious value.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

EBITDA Margin Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is a good EBITDA margin?
Entirely industry dependent. SaaS runs 20% to 40%, professional services 15% to 25%, manufacturing 8% to 18%, restaurants 8% to 15% and distribution just 3% to 8%.
How is EBITDA calculated?
Add depreciation and amortisation back to operating income. Here $372,000 of EBIT plus $96,000 of D&A gives $468,000.
Why do buyers use EBITDA instead of net income?
Because it strips out financing, tax and depreciation policy, letting them compare the underlying operation and then apply their own capital structure.
What is wrong with EBITDA?
It ignores capital expenditure. Here capex of $140,000 exceeds the $96,000 D&A charge, so EBITDA overstates real cash generation by $44,000.
What is the difference between EBITDA margin and operating margin?
Only depreciation and amortisation. The 4.00-point gap here between 19.50% and 15.50% is exactly the $96,000 D&A charge expressed as a share of revenue.
Should I use EBITDA or EBITDA less capex?
Use both. EBITDA for comparability against peers, EBITDA less capex to understand what the business actually generates.
What EBITDA multiple will my business sell for?
It depends on size, growth, sector and margin. Businesses above 80% gross margin earn a median 7.6 times against 5.5 times below, and clearing the Rule of 40 roughly doubles the premium.
What is adjusted EBITDA?
EBITDA with one-off or owner-specific items added back. Legitimate adjustments survive quality-of-earnings scrutiny; aggressive ones do not, and buyers test every one.
Does margin trend matter more than the level?
In M&A, generally yes. A business moving from 8% to 14% over three years typically prices better than one stable at 18% with no trajectory.
Why do lenders write covenants against EBITDA?
Because it approximates cash available to service debt before financing costs. Most require debt service coverage of at least 1.25 times.
Is EBITDA the same as cash flow?
No. It excludes capex, working capital movements, interest and tax. It is a proxy for cash, and a poor one for capital-intensive businesses.
What does it mean if capex is below depreciation?
The business is underinvesting relative to the rate its assets are being consumed. It flatters cash today and defers a bill that eventually arrives.
Do asset-light businesses need EBITDA at all?
Less so. Where D&A is minimal, EBITDA and EBIT converge and the add-back adds little insight.
How does EBITDA margin affect enterprise value?
Directly and multiplicatively. On $468,000 of EBITDA, the difference between a 5.5 times and a 7.6 times multiple is $982,800 of enterprise value.
Should owner salary be added back?
In a small-business sale, an above-market owner salary is commonly normalised. That figure is usually presented as seller discretionary earnings rather than EBITDA.
Can EBITDA margin exceed gross margin?
No. EBITDA is calculated after cost of goods sold, so gross margin remains the ceiling.
Is this ebitda margin calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
