SDE Multiple vs Revenue Multiple

What Is the Difference Between SDE Multiple and Revenue Multiple?

An SDE multiple values a business based on its Seller's Discretionary Earnings — the cash flow a full-time owner-operator takes home. A revenue multiple values a business based purely on top-line sales. For most small businesses under $5M in revenue, SDE multiples produce a more accurate valuation because they reflect actual profitability, not just size. For a refresher on the earnings side of this equation, see what is Seller's Discretionary Earnings.

Here is the practical difference in dollars. A landscaping company with $1.2M in revenue and $240K in SDE valued at a 3.0x SDE multiple is worth $720K. The same company valued at a 0.6x revenue multiple is worth $720K. The numbers match only when the profit margin and multiples align. When they don't, the gap can run six figures.

Why It Matters for Your Business Valuation

Buyers choose the multiple that matches the risk and growth profile of the business. Small Main Street businesses sold to individual operators almost always transact on SDE multiples of 2.0x to 4.0x. Larger businesses sold to private equity or strategic acquirers use EBITDA multiples of 4x to 8x. Revenue multiples dominate in three narrow categories: SaaS (3x-8x ARR), recurring-revenue services (1x-3x), and asset-light businesses where earnings are intentionally suppressed through reinvestment.

Using the wrong multiple is the single most common pricing mistake sellers make. A plumbing company owner who insists on a 1.0x revenue multiple because a SaaS founder got one is going to sit on the market for two years. A SaaS founder who prices on a 3.0x SDE multiple is going to leave $2M on the table. You can explore how multiples shift by industry in our guide to business valuation multiples by industry.

How to Use Both Multiples Correctly

Start with SDE. For any business under $2M in SDE, SDE multiples are the primary method buyers, brokers, and lenders use. Calculate clean SDE first — owner salary added back, personal expenses removed, one-time items stripped — then apply a comparable multiple based on industry, size, and growth.

Use revenue multiples as a sanity check, not a primary method. If your SDE-based valuation comes to $800K but the implied revenue multiple is 4.0x for a traditional service business, something is wrong. Either the SDE is overstated or the multiple assumption is too aggressive.

Three situations where revenue multiples should lead:

• SaaS and subscription businesses with 80%+ gross margins and strong net revenue retention
• High-growth companies reinvesting all cash flow into marketing or product
• Businesses with recurring contracts where predictable revenue commands a premium over current earnings

For everyone else — HVAC, landscaping, trucking, retail, professional services, restaurants — SDE is king. The reason is simple: individual buyers fund these deals with SBA loans, and SBA underwriters use SDE-based coverage ratios. If the SDE multiple doesn't support the price, the financing doesn't close.
