SDE vs EBITDA vs TTM: The Only Valuation Guide You Need in 2026

Ask five different people what a business is worth and you'll get five different answers — not because valuation is subjective, but because they're using different metrics. SDE, EBITDA, and TTM are the three most important financial concepts in small business valuation, and confusing them is one of the most common — and costly — mistakes buyers and sellers make. Understanding the difference isn't just academic. It's the difference between paying fair value and overpaying by $300,000 on a $1.5M deal.

This guide breaks down each metric in plain language, explains when each one applies (and when using the wrong one actively misrepresents a business), covers 2026 industry multiples for Main Street and lower-middle-market deals, demystifies legal add-backs, and gives you a simple framework to estimate any business's value in three minutes. Whether you're buying, selling, or just benchmarking your business, this is the foundation everything else is built on.

What Each Metric Means: SDE, EBITDA, and TTM Defined

These three terms get used interchangeably in casual conversation, but they measure very different things. The distinctions matter enormously when calculating a multiple-based valuation.

Seller's Discretionary Earnings (SDE): The Main Street Standard

Seller's Discretionary Earnings (SDE) is the total financial benefit that a full-time owner-operator derives from a business in a given year. It starts with net income from the business tax return and adds back:

• The owner's W-2 salary or owner's draw
• Depreciation and amortization
• Interest expense
• Non-recurring, one-time expenses (legal fees, equipment replacement, etc.)
• Owner personal expenses run through the business (personal vehicle, health insurance, phone, etc.)
• Non-cash expenses

SDE is the right metric for businesses with revenues under approximately $2–3 million where the owner is actively working in the business full-time. It answers the question: "How much total economic benefit does one full-time owner extract from this business?" The key distinction is that it includes the owner's compensation — the buyer is expected to replace the owner themselves.

For a practical deep dive on SDE and EBITDA differences, see our EBITDA vs. SDE valuation comparison guide.

EBITDA: The Middle-Market Standard

EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization — is the metric used for larger businesses where the owner's salary is replaced by a professional management team. EBITDA normalizes cash flow across companies with different capital structures, tax situations, and depreciation schedules, making it ideal for comparing businesses of similar size and industry.

The key difference from SDE: EBITDA does not add back the owner's compensation. Instead, it assumes that a market-rate management team is already in place (or will be hired post-close). This means EBITDA is always lower than SDE for the same business, which is why using EBITDA on a small owner-operated business dramatically understates its value for the right buyer.

When should you use EBITDA? For businesses with revenues above $2–3 million, management teams in place, and where the buyer is acquiring a company they will manage from a distance (or through professional managers) rather than operate themselves. Most private equity and institutional buyers use EBITDA exclusively.

TTM (Trailing Twelve Months): The Time Frame, Not the Metric

TTM — Trailing Twelve Months — is a time period designation, not a valuation metric in itself. It refers to the most recent 12-month period of financial data, rolling forward from the current month (e.g., May 2025 through April 2026 if you're valuing in April 2026). TTM financials are critical because they reflect the business's current performance trajectory, not just calendar-year snapshots.

Why does TTM matter so much? Because a business's most recent tax return is always at least three to fifteen months old. If the business has been growing rapidly, the tax return understates current performance. If it's been declining, the tax return overstates it. TTM financials — typically built from monthly P&L statements — capture the real current state of the business. Sophisticated buyers always calculate TTM SDE or TTM EBITDA alongside the 3-year average when making offers.

Adjusted EBITDA vs. Normalized EBITDA

You'll often hear "adjusted EBITDA" or "normalized EBITDA" in deal discussions. These terms describe EBITDA that has been recasted to remove one-time, non-recurring, or non-business items — making the underlying earnings power of the business clearer. Adjustments might include: removing a one-time legal settlement expense, adding back above-market owner salaries, eliminating a personal vehicle expensed through the business, or adjusting for a year with unusual insurance claims. The resulting "adjusted EBITDA" or "adjusted SDE" is the basis for valuation multiples.

2026 Industry Multiples: What Buyers Are Actually Paying

Valuation multiples represent how many times the relevant earnings metric a business sells for. A business with $400,000 SDE selling at a 3x multiple closes at $1.2M. At a 4x multiple, that's $1.6M. The difference between 3x and 4x on the same cash flow is $400,000 — which is why understanding where your business falls in the multiple range matters enormously.

Multiples are driven by industry, business size, revenue stability, growth trajectory, owner dependency, customer concentration, and overall market conditions. Here are 2026 benchmarks based on transaction data across Main Street and lower-middle-market deals:

Industry / Business Type	Typical Metric	2026 Multiple Range	Premium Drivers
HVAC / Plumbing / Electrical	SDE or EBITDA	3.5x – 5.5x	Recurring contracts, licensed techs
Landscaping / Lawn Care	SDE	2.5x – 3.5x	Commercial contract base, equipment value
Software / SaaS	EBITDA or Revenue	4x – 8x EBITDA	MRR growth, low churn, ARR base
Medical / Dental Practices	SDE or EBITDA	3x – 6x	Payer mix, patient retention, specialty
Restaurants / Food Service	SDE	1.5x – 3x	Long lease term, systemized ops
Manufacturing	EBITDA	3.5x – 5x	Proprietary processes, long-term contracts
Laundromats	SDE or Net Cash Flow	3x – 4.5x	Lease length, card-operated, low labor
Auto Repair / Tire Shops	SDE	2.5x – 3.5x	Real estate ownership, repeat customers
Staffing / Recruiting Agencies	EBITDA	3x – 5x	Recurring client relationships, niche focus
E-Commerce / DTC Brands	SDE or EBITDA	2.5x – 4x	Brand strength, platform diversification

These are market ranges, not guaranteed outcomes. Individual deals deviate based on business-specific factors. For a comprehensive breakdown of multiples by industry, see our 2026 EBITDA multiple benchmarks guide.

What Pushes a Business to the Top of Its Multiple Range?

Moving from the bottom to the top of a multiple range on a $400K SDE business is the difference between a $1M and $1.6M exit. The following factors reliably command premium multiples:

• Recurring or contracted revenue — Predictable cash flow reduces buyer risk and commands higher multiples universally
• Documented systems and SOPs — Businesses that run without the owner present are worth more
• Diversified customer base — No single customer representing more than 15–20% of revenue
• Clean, auditable financials — Three years of clean books with minimal unexplained variance
• Growth trajectory — TTM significantly above prior year averages justifies forward-looking multiple expansion
• Transferable relationships — Vendor agreements, customer contracts, and key employees willing to stay

Legal Add-Backs: What You Can (and Cannot) Justify in a Recast

Add-backs are the adjustments made to reported net income to arrive at true SDE or normalized EBITDA. They're legitimate, expected, and necessary for accurate valuation — but they're also one of the most contentious areas in deal negotiations. Understanding which add-backs will survive buyer and lender scrutiny is critical.

Add-Backs That Are Always Accepted

• Owner's salary and payroll taxes (for owner working in the business)
• Depreciation and amortization
• Interest expense
• Personal health insurance premiums paid by the business
• Personal vehicle expenses (the personal use portion)
• Life insurance on owner with business as beneficiary
• One-time legal, accounting, or consulting fees (with documentation)
• Non-recurring capital expenditure (e.g., a one-time roof replacement)

Add-Backs That Require Strong Documentation

• Above-market owner salary (requires market comp analysis for the role)
• Family member salaries for work that is not actually performed
• Personal travel, meals, and entertainment (estimate of personal vs. business use)
• Home office deduction (if owner operates from home)
• COVID-19 impact adjustments (now increasingly dated; buyers scrutinize these)

Add-Backs That Will Damage Your Credibility

• Revenue that never existed in bank statements
• "Cash" revenue claimed but undocumented (huge red flag)
• Large, recurring expenses claimed as "one-time"
• Add-backs that contradict the business tax returns
• Personal expenses without any documentation or business purpose

The quality of your recast matters as much as the numbers themselves. A professional recast with a clear add-back schedule, supporting documentation, and narrative context will survive due diligence and SBA underwriting. A recast that reads like it was designed to inflate earnings will destroy buyer trust.

The 3-Minute Valuation Calculator Framework

You don't need a valuation firm to get a working estimate of your business's value. Use this simple framework:

Step 1: Calculate Your TTM Net Income

Pull your last 12 months of P&L statements (monthly). Add up net income after all expenses.

Step 2: Add Back SDE Items

Add: your owner salary, payroll taxes on owner salary, depreciation, amortization, interest expense, personal health insurance, personal vehicle (business portion), and any clearly non-recurring items with documentation.

Step 3: Apply the Relevant Multiple

Use the industry table above to identify the appropriate multiple range. Start at the midpoint of the range, then adjust up for premium factors (recurring revenue, clean books, growth) and down for risk factors (owner dependency, customer concentration, declining revenue).

Step 4: Sanity Check With Market Comps

Search BizBuySell and Business Broker of Florida / IBBA transaction databases for recent sales of comparable businesses in your industry, region, and revenue range. Your estimate should be in the same ballpark as market comps — if it's significantly higher, examine why.

Frequently Asked Questions: SDE vs EBITDA vs TTM

Conclusion: Know Your Numbers Before You Enter Any Negotiation

Whether you're buying or selling a business in 2026, the three most important financial concepts you need to command are SDE, EBITDA, and TTM. Using the wrong metric miscalculates business value. Ignoring TTM misses the most current picture of performance. And failing to understand add-backs either leaves money on the table (for sellers) or leads to overpaying (for buyers).

The framework is not complicated once you understand the underlying logic. SDE captures total owner benefit for hands-on businesses. EBITDA captures management-team-run businesses. TTM captures current performance. Multiples translate these numbers into market value. And add-backs bridge the gap between tax return accounting and economic reality.
