What is SDE and how does it affect my valuation?
SDE — Seller’s Discretionary Earnings — is the single most important number in a small business valuation. If you are a small business owner thinking about selling, understanding SDE is not optional. It is the foundation that most valuations are built on, and it has a direct and significant impact on what your business is worth.
The good news is that once you understand what SDE is and how it is calculated, you will have a much clearer picture of your business value — and more importantly, what you can do to increase it.
What Does SDE Actually Mean?
SDE represents the total financial benefit a single full-time owner-operator receives from owning and running the business. It answers one simple question for a potential buyer:
“If I bought this business and ran it myself, how much money would I make in a year?”
That number includes more than just your salary. It captures every dollar of economic benefit flowing to you as the owner — profit, compensation, and any personal expenses the business pays on your behalf.
How Is SDE Calculated?
SDE starts with your net profit and adds back several items that are specific to you as the current owner but would not necessarily carry over to a new owner. This process is called a recast or normalization of earnings.
The standard SDE formula is:
Net Profit
+ Owner’s salary or draw
+ Owner’s personal expenses run through the business
+ Depreciation and amortization
+ Interest expense
+ Any one-time or non-recurring expenses
= SDE
Here is a practical example:
| Item | Amount |
|---|---|
| Net profit | $80,000 |
| Owner salary | $90,000 |
| Owner’s vehicle (business paid) | $12,000 |
| Owner’s cell phone (business paid) | $2,400 |
| One-time legal expense (non-recurring) | $8,000 |
| Depreciation | $15,000 |
| Total SDE | $207,400 |
Notice how dramatically different $207,400 looks compared to the $80,000 net profit on the surface. This is why business owners are often surprised — in a good way — when they see their true SDE for the first time.
What Gets Added Back to SDE?
Understanding what qualifies as an addback is critical because every dollar you can legitimately add back increases your SDE — and therefore your valuation. Common addbacks include:
Owner compensation
Your salary, draws, distributions, or any other form of compensation you take from the business. A new owner would pay themselves from this same pool of earnings, so it is added back to show the true earning power of the business.
Owner personal expenses
Expenses that benefit you personally but are paid by the business — a company vehicle you use personally, your cell phone, health insurance premiums, travel, meals, or a home office. These are real expenses on your books but would not necessarily continue under new ownership.
Depreciation and amortization
These are non-cash accounting entries that reduce your reported profit but do not represent actual money leaving the business. They are added back because they do not affect the real cash the business generates.
Interest expense
Interest on business loans is specific to your current financing structure. A buyer may pay cash or finance the purchase differently, so interest is added back to show earnings before financing decisions.
One-time or non-recurring expenses
Anything that was an unusual, one-time cost that is unlikely to repeat — a major repair, a lawsuit settlement, a one-time marketing campaign, or equipment replacement. These expenses reduce profit in the year they occur but do not reflect the ongoing earning power of the business.
Owner family members on payroll
If you pay family members who do not actively work in the business, or who are paid above market rate for what they do, the excess compensation may be added back as a normalization adjustment.
How Does SDE Affect My Valuation?
Once your SDE is calculated it is multiplied by an industry-specific number called a multiplier to arrive at your estimated business value. This is where SDE becomes incredibly powerful — small increases in SDE produce large increases in valuation.
Here is an example using a 2.5x multiplier:
| SDE | Multiplier | Business Value |
|---|---|---|
| $150,000 | 2.5x | $375,000 |
| $175,000 | 2.5x | $437,500 |
| $200,000 | 2.5x | $500,000 |
| $250,000 | 2.5x | $625,000 |
Notice that a $100,000 increase in SDE results in a $250,000 increase in business value at a 2.5x multiplier. This is why business brokers and exit planning advisors focus so heavily on improving SDE in the years leading up to a sale — the payoff is multiplied.
What Factors Influence the Multiplier Applied to Your SDE?
Your SDE is only half of the equation. The multiplier applied to it can vary significantly based on several factors:
- Industry — some industries command higher multiples than others based on risk and buyer demand
- Business size — larger SDE figures typically attract higher multipliers because the business is less dependent on a single owner
- Growth trend — a business growing year over year commands a premium over a flat or declining business
- Owner dependence — if the business cannot operate without you, buyers will discount the multiplier because of transition risk
- Customer concentration — if one or two customers represent the majority of revenue, buyers see higher risk and apply a lower multiple
- Recurring revenue — contracts, subscriptions, and repeat customers increase predictability and command higher multiples
- Documented systems and processes — a business with clear operating procedures is easier to transition and more valuable to buyers
How Can I Increase My SDE Before Selling?
This is the question every business owner should be asking at least two to three years before they plan to sell. Here are the most impactful ways to increase your SDE:
- Increase revenue — grow top-line sales through new customers, products, or markets
- Reduce unnecessary expenses — cut costs that do not contribute to revenue or growth
- Document and add back all legitimate owner benefits — make sure every personal expense run through the business is captured
- Eliminate one-time expenses — avoid large non-recurring costs in the years leading up to sale
- Reduce owner dependence — build a management team that can run the business without you
- Develop recurring revenue — shift to contracts, retainers, or subscription models where possible
- Clean up your books — well-documented, professionally prepared financials increase buyer confidence and reduce due diligence risk
A Note on Accuracy
The SDE figure you enter into the calculator does not need to be perfect. A reasonable estimate based on your best recollection of last year’s financials will give you a meaningful valuation range to work with. When you are ready for a formal valuation — especially in preparation for an actual sale — work with a business broker or CPA to prepare a fully recasted SDE with proper documentation.
