How to Calculate Seller’s Discretionary Earnings (SDE)

Key Takeaways: Understanding Seller’s Discretionary Earnings (SDE)

SDE is the most important valuation metric for small to mid-sized, owner-operated businesses.
It reflects the total financial benefit to a new owner—including salary, discretionary expenses, and one-time costs added back to net profit.
SDE can be used as earnings, but also to pay down acquisition debt or reinvest in the business.
Use SDE instead of EBITDA if you’re actively running your business and generating under $5 million in annual revenue.
A clean, well-documented SDE supports higher valuations and attracts more serious buyers.

When it comes to valuing small to mid-sized businesses, the most important metric to consider is Seller’s Discretionary Earnings (SDE). Net profit reflects what is left after expenses, but SDE offers a full picture of the financial benefit that the business earns for the owner. This is a crucial metric for potential buyers to consider, as it helps them determine how much they can expect to take home.

Any owner looking to sell their business needs to understand SDE and how to properly calculate it. Otherwise, they face the risk of potentially undervaluing their business or turning off serious buyers who don’t have a full view of the business’s earnings.

Continue below, where we will dive deeper into this topic and how to determine seller's discretionary earnings.

What Are Seller’s Discretionary Earnings?

Seller’s Discretionary Earnings is a metric that represents the total financial benefit that a full-time owner/operator receives from the business annually. It differs from net income in that it adds back certain expenses that may not carry to the new owner. This gives a full picture of what the new owner can expect to earn.

Other names for SDE include Adjusted Cash Flow, Owner’s Benefit, and Recast Earnings.

Example of Seller’s Discretionary Earnings

Let’s take, for example, a landscaping business where the owner pays themselves a $60,000 salary. However, they also pay their car and phone expenses through the business, and also a one-time legal fee of $5,000. These expenses will be added back to the net profit to normalize the earnings and give buyers a more accurate picture of expected earnings.

SDE is primarily relevant to selling small and Main Street businesses. Larger corporations will typically have more complex financial structures and use different metrics.

How to Determine Seller’s Discretionary Earnings

Calculating SDE is a relatively straightforward process that can be done step-by-step. Each step will consider additional factors or expenses that may be added back to the earnings. Follow the steps below.

Step 1: Start with Net Profit or Pre-Tax Income

The first step of the process is to start with the net profit or pre-tax income shown on the business’s Profit and Loss (P&L) statement. This figure can be found at the bottom of the statement and will serve as the base of the SDE calculation.

It is a good baseline because it shows quickly what the business has earned through normal annual operations after all expenses have been deducted. Now, we need to add back expenses that won’t carry over to show the true earning potential.

Step 2: Add Back Owner’s Compensation

The immediate expense to add back is the salary of one full-time owner/operator. However, if there is more than one, they should only be added back if the new owner doesn’t need to replace them. Otherwise, they must be replaced at the market rate.

Step 3: Add Back Standard Adjustments

Next, add back standard non-cash or financing-related adjustments, such as:

Depreciation
Amoritization
Interest Expense
Owner Payroll Taxes

Step 4: Add Back Discretionary Expenses

Now, add back personal or non-essential expenses that have been run through the business. Some examples of these include:

Club Memberships
Personal Travel
Charitable Donations
Owner’s Cell Phone
Personal Vehicle Payments.

Step 5: Add Back Non-Recurring or One-Time Expenses

Next, add back any non-recurring or one-time expenses. These can distort true earnings, as they are not a regular expense or obligation throughout the year. Some examples include:

Emergency Repairs
Legal Settlements
Unusual Tech Purchases

Step 6: Subtract Non-Operating Income

Lastly, you will need to deduct any income that isn’t included in normal business operations or won’t carry over to the new owner. For example:

Asset Sales
Insurance Payouts
Rental Income from Personal or Unrelated Properties

Simplified SDE Formula:

Sellers Discretionary Earnings (SDE) = Net Profit + Owner Salary + Interest + Taxes + Depreciation + Amortization + Discretionary + Non-Recurring – Non-Operating Income

Common Add-Back Examples: What Counts and What Doesn’t

It’s important to understand which add-backs count and which don’t. Some are considered standard or widely accepted in SDE calculations, but others may raise red flags for buyers without justification for their inclusion. There are three categories to distinguish add-backs:

Clearly Acceptable SDE Add-Backs

These are add-backs commonly included within SDE calculation that most buyers will accept without question:

One Owner’s Salary
Depreciation and Amortization
Interest Expense
Owner’s Health Insurance

Gray Area Items (Need Justification)

These may qualify, but only if the seller can clearly explain their inclusion with valid reasoning:

Business Travel with Partial Personal Benefit
Meals and Entertainment
Charitable Donations

Not Acceptable SDE Add-Backs

These are expenses that will generally never be accepted by serious buyers:

Expenses benefitting employees or the business itself
Multiple owner salaries (Beyond the initial one)
Rent at Market Rate (unless below-market correction is needed).

Remaining transparent and honest with add-backs will maintain credibility and ensure the valuation remains accurate even under buyer scrutiny.

What Is the Difference Between SDE and EBITDA?

Another commonly used metric in business sales is Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA). SDE and EBITDA metrics are not interchangeable, and each is used in different ways for different types of businesses.

You should use SDE if you’re a sole owner actively running the business and generating less than $5 million in revenue. EBITDA should be used if the business has management staff and you are not involved in the daily operations.

Here’s a further breakdown of each metric:

Aspect	SDE	EBITDA
Use Case	Used when the owner actively manages the business	Used when the business has management in place or the owner is not involved
Business Size	Typically for businesses with under $5M in revenue	Commonly used for mid-market and larger businesses
Owner’s Salary	Adds back one owner’s salary	Does not add back the owner’s salary
Discretionary Expenses	Adds back personal/discretionary expenses	Excludes personal expenses; assumes professional financials
Reflects	What a single owner-operator earns	The performance of the business is independent of owner involvement
Valuation Use	Small business valuations (main street buyers, owner-operators)	Institutional valuations (PE firms, strategic/investment buyers)

It is vital to employ the right metric, as using the wrong one can either undervalue or overvalue your business. This can lead to either you profiting less from the sale or turning off serious buyers.

SDE Calculation Example: What a Buyer Really Sees

To clarify the application of SDE, let’s break it down into a real-world example:

Let’s look at a fictional HVAC business with the following financials:

Pre-Tax Income (EBT): $275,000
Owner’s Salary: $85,000
Interest Payments: $12,000
Depreciation & Amortization: $18,000
Owner’s Discretionary Expenses (e.g., personal meals, phone plan): $22,000
One-Time Renovation Expense (non-recurring): $8,000.

As mentioned in our steps for calculating SDE above, we start with the pre-tax income of the business. Then, we need to add back any items that reflect the owner’s personal benefit, as well as non-essential or one-time costs. Making these adjustments helps to reflect how much a new owner-operator could potentially earn after buying the business. Here is a breakdown of the formula:

SDE = $275,000 (EBT)

+ $85,000 (Owner’s Salary)

+ $12,000 (Interest)

+ $18,000 (Depreciation & Amortization)

+ $22,000 (Discretionary Expenses)

+ $8,000 (Non-Recurring Expense)

= $420,000

So, a buyer considering purchasing the business could reasonably expect to take home $420,000 per year when stepping into the owner role. However, SDE isn’t just about take-home pay—it represents the total financial benefit available to a buyer. These earnings can also be used to pay off acquisition-related debt, reinvest in the business through capital improvements, or support future growth initiatives. This helps you to determine and justify the right asking price, and gives buyers confidence in the business’s potential.

Why SDE Matters for Sellers and Buyers

We started off this article by mentioning that SDE is the most important metric when selling a small to mid-sized business. This is because it is the foundation of how these businesses are valued, marketed, and sold. It offers a clear and concise answer to buyers asking: How much can I realistically make if I run this business?

This helps them determine whether it meets their goals and expectations, and justifies any risk of buying. Moreover, it helps you determine a realistic asking price through an SDE multiple. A multiple simply means a factor ranging from 2x to 4x the SDE, depending on industry, growth trends, location, and other factors.

An example of a multiple:

If your SDE is calculated at $300,000 and the average industry multiple is 3x, you may be able to sell your business for ~$900,000.

A clear, credible, and accurate SDE figure is vital to give buyers confidence in the sale. Not only does it attract serious buyers and lenders, but it can also help you achieve much better offers.

Tips for Getting the Cleanest SDE Before You Sell

If you are planning to sell your business, the sooner you start preparing, the better. This will let you present a strong and defensible SDE when it is time to sell. Here are some tips for preparation even years before selling:

Stop running personal expenses through the business
Keep business and personal accounts separate
Avoid gray-area expenses (e.g. mixed personal/business travel)
Maintain clean financial records (P&Ls, balance sheets, tax returns)
Work with a CPA to identify legitimate add-backs.

Well-documented financials, or “clean books,” give buyers much more confidence in the sale and reduce the perceived risk. Both of these help you to achieve smoother negotiations, faster sales, and ultimately, better offers for your business. Don’t neglect to start preparing as soon as possible.

Know Your Value Before You Sell, Start with a Confidential Valuation

Whether you are considering selling soon or just starting to consider it, understanding SDE is a crucial step in the process. It will help you to start getting everything in order to provide an accurate SDE to demonstrate your business’s worth to potential buyers. Remember, you don’t need to be ready to sell today to start preparing. Anytime is a good time to start getting everything in order.
