EBITDA Calculator (2026) — SMB Earnings Quality + Adjusted EBITDA
EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization — is the standard SMB earnings-quality proxy. Lenders use it to underwrite financing. Buyers use it to value acquisitions. SBA loan officers use it in DSCR calculations. This calculator computes EBITDA, EBIT, net income, and EBITDA margin from your income-statement basics — and adds an Adjusted EBITDA view with the standard SMB-transaction add-backs (owner comp above market, one-time items, related-party rent above market) that lenders and buyers actually underwrite to.

How it works
Methodology
Inputs
- Revenue
- Top-line revenue for the period (typically trailing 12 months for a transaction-grade EBITDA).
- Cost of Goods Sold (COGS)
- Direct costs of producing what you sell. Excludes overhead and indirect costs.
- Operating Expenses (excl. D&A)
- SG&A, marketing, rent, payroll, etc. — but NOT depreciation or amortization (they're separate inputs).
- Depreciation
- Non-cash charge against fixed-asset basis. Pull from your P&L D&A line or fixed-asset schedule.
- Amortization
- Non-cash charge against intangibles (goodwill, patents, customer lists, etc.).
- Interest Expense
- Total interest paid on debt for the period.
- Tax Expense
- Income tax expense for the period.
- Owner compensation above market (optional)
- Adjusted EBITDA add-back. Only the portion above what a market-rate hire would cost.
- One-time / non-recurring items (optional)
- Adjusted EBITDA add-back. Genuine one-time items only — recurring items don't qualify.
- Related-party rent above market (optional)
- Adjusted EBITDA add-back. The above-market portion of rent paid to an owner-controlled entity.
Formula
Operating Income (EBIT) = Revenue − COGS − OpEx EBITDA = EBIT + Depreciation + Amortization Net Income = EBIT − Interest Expense − Tax Expense EBITDA margin = EBITDA ÷ Revenue × 100 Adjusted EBITDA = EBITDA + owner-comp add-back + one-time add-backs + related-party rent add-back Adjusted EBITDA margin = Adjusted EBITDA ÷ Revenue × 100
Assumptions
- OpEx input EXCLUDES depreciation and amortization (they're separate inputs that get added back). If your P&L bundles D&A inside OpEx, subtract it before entering.
- Net income approximation doesn't model interest income, other income, gains/losses on asset disposal, equity-method earnings, or discontinued operations. For a clean SMB operating business those are typically immaterial.
- Adjusted EBITDA add-backs must be genuinely supportable. In transaction due diligence, aggressive add-backs get challenged hard — get them documented before relying on them.
- Verdict band thresholds (8% / 10% / 15% margin) are screening heuristics based on conventional bank, SBA, and non-bank underwriting patterns. Actual financeability depends on the full file, not margin alone.
- Industry context matters — software and services run at much higher EBITDA margins than retail or restaurants. The verdict band doesn't normalize for industry. Use industry comps when making transaction or financing decisions.
- Educational tool only. Not financial, tax, accounting, or valuation advice. Talk to your CPA before relying on an Adjusted EBITDA figure in a transaction.
Worked examples
$1M revenue · clean services business · no add-backs
- Revenue
- $1,000,000
- COGS
- $400,000
- OpEx (excl. D&A)
- $350,000
- Depreciation
- $30,000
- Amortization
- $10,000
- Interest
- $25,000
- Tax
- $40,000
EBIT = $250,000. EBITDA = $290,000 (29% margin). Net income = $185,000. Margin is well above the 15% bank-tier threshold — on margin alone, conventional bank financing typically pencils. Valuation context: ~4–6× EBITDA SMB transaction multiple would imply a $1.2M–$1.7M enterprise value range, subject to industry, growth, and concentration adjustments.
$2M revenue · owner-operated · with Adjusted EBITDA add-backs
- Revenue
- $2,000,000
- COGS

EBIT = $150,000. Reported EBITDA = $200,000 (10% margin). Adjusted EBITDA = $305,000 (15.3% margin) after $80K owner-comp normalization and $25K one-time legal expense. Reported margin sits at the SBA-financeable line; Adjusted margin clears bank-tier — exactly why lenders underwrite to Adjusted EBITDA, not reported.
$500K revenue · thin-margin retail · lender concern band
- Revenue
- $500,000
- COGS

- OpEx (excl. D&A)
- $170,000
- Depreciation

EBIT = $30,000. EBITDA = $38,000 (7.6% margin). Net income = $22,000. Margin is below the 8% non-bank threshold — underwriters typically flag the file at this level. Before pursuing financing, look for legitimate add-backs and revisit pricing/expense lines; revenue-based products that flex with actual cash flow may be the better fit.
Frequently asked
Questions readers ask
What is EBITDA, exactly? +
EBITDA = Earnings Before Interest, Taxes, Depreciation, and Amortization. It strips three sources of noise out of net income: capital-structure noise (interest), tax-jurisdiction noise (tax), and non-cash noise (D&A). What's left is a directional proxy for operating cash-generation capacity. It's not a GAAP measure, but it's the standard SMB lending and M&A shorthand because it's harder to manipulate than net income and more comparable across businesses with different debt loads and tax situations.
What's the difference between EBITDA and Adjusted EBITDA? +
Adjusted EBITDA normalizes for items that don't carry forward to a new owner or wouldn't recur. The standard SMB-transaction add-backs are: owner compensation above market (the portion of owner pay above what a market-rate hire would cost), genuine one-time items (legal settlements, non-recurring consulting, one-time asset write-downs), and related-party rent above market (if you own the building and lease to your business at above-market rent). Lenders and buyers underwrite to Adjusted EBITDA — reported EBITDA understates earnings power for owner-operated SMBs because owner comp is often above market.
What's a good EBITDA margin for a small business? +
Industry-dependent, but a rough screening heuristic: 15%+ is bank-tier, 10–15% is SBA-financeable, 8–10% is non-bank territory, below 8% raises lender concerns. Software and services businesses run higher (25%+); retail, restaurants, and contractors run lower (5–15%); commodity wholesale can run very thin. The verdict band in this calculator is screening guidance, not lender-specific underwriting. Talk to your lender or M&A advisor for industry comps.
How do lenders use EBITDA in underwriting? +
Most commonly via the debt service coverage ratio (DSCR): EBITDA (or a similar cash-flow proxy) divided by total annual debt service. Conventional bank lenders typically want DSCR ≥ 1.25; SBA 7(a) and 504 typically want 1.15–1.25 with some flexibility for strong files. EBITDA also feeds the leverage ratio (Debt ÷ EBITDA), which most bank-tier SMB lenders cap around 3-4× for healthy operating businesses. For DSCR math specifically see the DSCR Calculator.
How do buyers use EBITDA in valuation? +
SMB valuations are typically expressed as a multiple of Adjusted EBITDA — for example, 'this business sold for 4.2× EBITDA.' Common SMB ranges in 2026: 2–3× for thin-margin or single-customer-concentrated businesses, 3–5× for typical operating SMBs with diversified revenue, 5–8× for high-margin or growing businesses, and higher for SaaS / professional services with recurring revenue. The multiple depends heavily on industry, growth rate, customer concentration, and owner-dependence — these ranges are directional only.
Should I include owner salary in OpEx for this calculator? +
Yes — enter owner compensation as part of OpEx, then if owner comp is above market, separately enter the above-market portion as an Adjusted EBITDA add-back. Example: owner takes $250K, market-rate replacement would cost $150K. Include the full $250K in OpEx (which lowers reported EBITDA), then add back $100K as 'owner compensation above market' (which raises Adjusted EBITDA). The Adjusted EBITDA figure is what a buyer or lender would underwrite.
What about depreciation on leased equipment? +
Standard capital-lease and finance-lease depreciation runs through your P&L and adds back to EBITDA. Operating leases (now treated as right-of-use assets under ASC 842 since 2019) don't generate depreciation — the rent expense sits in OpEx and is NOT added back. If you're not sure which treatment applies to your leases, ask your CPA before relying on this calculator for a transaction.
Is this calculator a substitute for a CPA-reviewed financial statement? +
No. This is a quick directional tool for an SMB owner who wants to see their numbers through a lender's or buyer's lens. For any actual transaction (financing, acquisition, sale, refinance), you need CPA-reviewed financials and likely a quality-of-earnings analysis. The Adjusted EBITDA add-backs in particular get aggressively challenged in due diligence — get them documented and supportable before relying on them in a deal.
