What Is EBITDA and How Is It Used to Value a Business?
Ryan C. Winter Updated July 24, 2026
Short answer: EBITDA is earnings before interest, taxes, depreciation, and amortization: a measure of what the core operation actually generates. Buyers and lenders use it to compare businesses on a level footing, and an EBITDA margin, EBITDA divided by revenue, is judged against your industry’s norms and your own trend, not against a universal number.
If you have spoken to anyone about selling a business, you have heard the term EBITDA. It is the metric buyers, lenders, and advisors lean on to evaluate and price businesses. I am a business broker based in St. Augustine working with owners throughout Florida, and here is what it means, how to calculate it, and, since it is the question owners actually type into Google, what a “good” EBITDA margin really looks like.
What Does EBITDA Stand For?
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures operating profitability by stripping out financing decisions (interest), tax strategy (taxes), and non cash accounting entries (depreciation and amortization) to show how much the core operation generates. The SEC’s investor glossary has the formal definition; what matters for a seller is that it is the number a buyer’s lender will build the whole deal around.
How to Calculate EBITDA
Start with net income from your income statement, then add back:
- Interest expense on business loans or lines of credit
- Income tax expense
- Depreciation on equipment, vehicles, and furniture
- Amortization on intangibles like software or purchased goodwill
Illustration: a Florida HVAC company with $180,000 in net income adds back $25,000 of interest, $60,000 of taxes, $45,000 of depreciation, and $10,000 of amortization, for EBITDA of $320,000. Same company, very different looking number, and the second one is what a buyer’s analysis starts from.
Normalizing: The Add-Backs That Matter
Raw EBITDA rarely tells the whole story of a privately held business. Buyers work from adjusted EBITDA, which also normalizes one time expenses, above or below market owner compensation, and personal costs running through the company. Every adjustment needs a paper trail. An add back you cannot document is an add back the buyer’s lender will not accept, and undocumented adjustments are one of the quiet ways deals reprice during diligence.
EBITDA vs. SDE: Which Applies to Your Business?
Smaller, owner operated businesses are usually measured on seller’s discretionary earnings instead, which adds back the owner’s full salary and benefits on top of the standard adjustments, because the buyer of an owner operated business is typically replacing you. Larger businesses, where a manager runs operations, are measured on EBITDA. There is no bright line between the two. It depends on the size and structure of the business and who the likely buyer is, and part of positioning a business for sale is knowing which lens your buyer will use.
What Is a Good EBITDA Margin?
Your EBITDA margin is EBITDA divided by revenue. It is the question owners most want a single number for, and the honest answer is that no universal number exists. Margins vary enormously by industry, because industries carry different cost structures: a software company keeps a very different share of each revenue dollar than a grocery store, and both can be excellent businesses.
What buyers actually evaluate is threefold. Your margin against your industry’s norms: a business earning meaningfully better margins than its peers is demonstrating pricing power or operating discipline, and buyers notice. Your trend: a stable or improving margin over several years reads as durable; an eroding one reads as risk, whatever the level. Durability: whether the margin survives an ownership change, or depends on the owner underpaying themselves, deferring maintenance, or leaning on one outsized customer.
If you want to improve your margin before selling, favor changes that endure: pricing corrections, a better revenue mix, genuine cost discipline. Buyers discount margin that was manufactured for the listing, and slashing necessary spending the year before a sale is one of the most transparent moves an owner can make.
How EBITDA Turns Into a Price
Buyers apply a multiple to EBITDA, and what moves that multiple is risk: recurring revenue, customer diversification, a team that runs the business, clean books, and growth push it up; owner dependence and concentration pull it down. Multiples vary considerably by industry and size, which is why pricing from comparable completed sales beats any rule of thumb.
Frequently Asked Questions
What is a good EBITDA margin for a small business?
There is no universal benchmark. A healthy margin is one that compares well with your industry’s norms, has held steady or improved over several years, and does not depend on the current owner’s personal sacrifices to exist. Judged that way, businesses in very different industries can both have excellent margins at very different levels.
Is EBITDA the same as cash flow?
No, and buyers know the difference. EBITDA ignores capital expenditures, working capital needs, and debt payments. A business that must constantly reinvest in equipment can show strong EBITDA and weak actual cash flow, which is why buyers of equipment heavy businesses look hard at capex alongside EBITDA.
Should my business be valued on EBITDA or SDE?
If you run the business yourself day to day, buyers will usually think in SDE. If a management team runs it and you oversee, EBITDA. The distinction matters because the two numbers can differ by the entire cost of an owner’s salary, and using the wrong one misprices the business in either direction.
How do I increase my EBITDA before selling?
Document every legitimate add back, correct underpricing, tighten genuinely wasteful spending, and reduce the business’s dependence on you. Give the changes time to show in the financials. A single strong year is a start; a visible trend is what moves valuations.
