How EBITDA is calculated
EBIT = Net income + Interest expense + Tax expense
EBITDA = EBIT + Depreciation + Amortization
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. Starting from net income and adding back these four items strips out the effects of financing decisions (interest), tax structures (taxes), and non-cash accounting charges (D&A) — leaving a number that approximates the cash-generating power of the business's core operations.
EBIT (earnings before interest and taxes) removes the financing and tax distortions but keeps D&A. It is sometimes called operating income or operating profit. EBITDA adds D&A back on top of EBIT, making it a rougher but more widely comparable proxy for operating cash flow — especially useful for asset-heavy businesses where D&A is a large non-cash charge.
EBITDA margin benchmarks by industry
| EBITDA margin | Typical for |
|---|---|
| ≥25% | Strong — software, professional services, pharmaceutical, high-margin specialty businesses |
| 15–24% | Healthy — healthcare services, business services, light manufacturing, strong retailers |
| 5–14% | Fair — general retail, restaurants, construction, light distribution |
| <5% | Thin — grocery, commodity distribution, high-volume low-margin businesses |
EBITDA margins vary enormously by industry. A 10% EBITDA margin is excellent for a grocery distributor and weak for a software company. Compare your margin to your industry peers rather than a universal standard.
How lenders and buyers use EBITDA
Loan underwriting: Many lenders use EBITDA as a starting point for calculating debt service coverage. A simplified lender formula is EBITDA ÷ annual debt service, sometimes called the DSCR. Lenders typically want this ratio above 1.25×. Unlike NOI-based DSCR, EBITDA-based coverage adds back D&A, which increases the apparent cash available to service debt — this is more favorable for asset-heavy businesses that carry significant depreciation charges.
Business valuation: Private equity buyers and M&A transactions typically price businesses as a multiple of EBITDA — for example, 4× EBITDA for a small manufacturing business or 8× for a growing services firm. The business valuation calculator lets you apply a specific multiple to your EBITDA or SDE to estimate enterprise value.
Why EBITDA, not net income: Net income is easy to manipulate through depreciation schedules, interest structures, and tax elections — all of which vary across businesses with identical underlying operations. EBITDA normalizes these out. A buyer comparing two otherwise identical businesses — one that owns its equipment outright and one that leases — will see very different net incomes but similar EBITDAs.
Worked examples
Example 1 — HVAC services company:
| Item | Amount |
|---|---|
| Revenue | $1,200,000 |
| Net income | $95,000 |
| + Interest expense | $28,000 |
| + Tax expense | $32,000 |
| = EBIT | $155,000 |
| + Depreciation & amortization | $45,000 |
| = EBITDA | $200,000 |
| EBITDA margin | 16.7% — Healthy |
At a 4× EBITDA multiple, this company's estimated enterprise value is $800,000. A lender evaluating a $200,000 equipment loan would note that EBITDA covers annual debt service comfortably at current interest rates, supporting approval.
Example 2 — restaurant with negative net income:
| Item | Amount |
|---|---|
| Revenue | $900,000 |
| Net income | −$18,000 |
| + Interest expense | $22,000 |
| + Tax expense | $0 |
| = EBIT | $4,000 |
| + Depreciation & amortization | $38,000 |
| = EBITDA | $42,000 |
| EBITDA margin | 4.7% — Thin |
Despite a small net loss, EBITDA is positive — the business generates cash before non-cash D&A charges. A lender evaluating this restaurant would focus on whether the $42,000 in EBITDA covers proposed debt service. At a 1.25× coverage requirement, this supports up to $33,600/year ($2,800/month) in new debt service. The thin EBITDA margin also signals limited runway to absorb a revenue decline — a lender would want to see the trend improving.
Assumptions and limitations
- EBITDA is not cash flow. EBITDA ignores capital expenditures (capex), changes in working capital, and principal repayments. A business with high EBITDA but constant reinvestment in equipment may have very little free cash flow available to service debt. Free cash flow (EBITDA − capex − change in working capital − debt principal) is a more complete picture of actual cash availability.
- Depreciation add-back can mislead. Adding back depreciation assumes the asset does not need replacement. For businesses with aging equipment or infrastructure, the real economic cost is the eventual capex — not zero. This is why some lenders use "adjusted EBITDA" that caps the D&A add-back based on estimated maintenance capex.
- One-time items require adjustment. EBITDA from a single year's income statement may include non-recurring gains or losses — an insurance settlement, a one-time legal fee, a PPP loan forgiveness. Lenders and buyers typically adjust EBITDA to remove these items before applying a multiple or coverage ratio.
Frequently asked questions
- What is the difference between EBITDA and SDE?
- SDE (seller's discretionary earnings) is the standard for valuing small, owner-operated businesses. It starts with EBITDA and adds back the owner's compensation and personal expenses run through the business — the assumption being that a buyer will replace the owner and recapture those expenses. EBITDA is used for larger businesses where the owner is not the sole operator. The business valuation calculator lets you apply a multiple to either SDE or EBITDA.
- Why do lenders sometimes use EBITDA instead of net income?
- Net income is affected by financing decisions (interest) and tax structure (elections, deductions) that vary across businesses and can be actively managed. A business owner who maximizes deductions will show low net income but healthy underlying operations. EBITDA strips those out to show the operating earnings the business produces before the owner's financial engineering. For loan underwriting, the lender wants to know if the business generates enough operating cash to cover debt service — EBITDA is the closest income-statement approximation of that figure.
- How many years of EBITDA should I show a lender?
- Most lenders want two to three years of tax returns and financial statements. They will typically average or weight recent years, with the most recent year carrying the most weight. A single strong year after two weak ones may be discounted. For an SBA loan, the lender is required to use the average of three years of global cash flow (personal plus business income) to calculate debt service capacity.
- Can EBITDA be negative?
- Yes. Negative EBITDA means the business's core operations are consuming cash before accounting for capital structure. This is common in early-stage businesses and those going through a restructuring. Most conventional lenders will not approve new term debt for a business with negative EBITDA. Businesses in this position typically need equity investment, revenue-based financing, or a turnaround plan before bank financing is available.
