What it means
When you look at a small business's standard profit and loss statement, the bottom line often fails to show the real money the business generates. This happens because small business owners frequently mix personal and business finances.
They might pay themselves a high salary, put personal travel through the company, or pay for family members to work part-time. Seller's Discretionary Earnings, often called SDE, strips away these choices to reveal the true financial benefit a new owner would receive.
SDE is the standard measure used when buying or selling small businesses, typically those with a value under two million pounds or fewer than twenty employees. Buyers need to know what cash flow will remain after they take over the operations.
By normalizing the earnings, buyers can fairly compare different businesses, regardless of how the previous owners chose to pay themselves or run their personal expenses through the accounts. To calculate SDE, start with the net operating profit before taxes.
Then, add back the single owner's salary, interest expenses, depreciation, and any non-business or personal expenses paid by the company, such as a company car or health insurance. You also add back any one-off, non-recurring expenses that will not happen again under new ownership, like a legal settlement or a major office refit.
While SDE is powerful, it requires careful verification. Buyers must scrutinise every add-back to ensure it is legitimate.
If an owner claims forty thousand pounds of personal expenses, they must prove those costs. Overstating SDE artificially inflates the asking price of a business, which can lead to failed negotiations or loans being denied by banks during the purchase process.
In practice
Real-world examples.
Example
A local cafe reports a net profit of twenty thousand pounds. The owner pays themselves a salary of thirty thousand pounds and charges five thousand pounds of personal travel to the business. The SDE is fifty-five thousand pounds.
Example
A boutique consultancy shows a net profit of forty thousand pounds. The sole owner takes twenty thousand pounds in salary and expenses ten thousand pounds for a home office allowance. The SDE totals seventy thousand pounds.
Example
An independent hardware store reports a net profit of fifty thousand pounds. The owner includes forty thousand pounds in salary and ten thousand pounds for a one-off roof repair. The calculated SDE is one hundred thousand pounds.
Think of it
“SDE is like looking at the fuel efficiency of a second-hand car after removing all the heavy personal junk in the boot. It shows you how the vehicle performs on its own, rather than how weighed down it was by the previous driver.
Formula
Calculation
Net Operating Profit + Owner's Salary + Owner's Personal Expenses + Interest & Tax + Non-Cash Expenses (Depreciation) - Non-Operating Income = SDE. Example: £30,000 net profit + £40,000 owner salary + £5,000 car lease + £10,000 depreciation = £85,000 SDE.Case study
Seen in the real world.
Jane wanted to sell her pet grooming business, Paws and Claws, and listed the net profit as twenty-five thousand pounds on her tax return. A savvy business broker advised her to calculate her Seller's Discretionary Earnings to attract serious buyers. They reviewed the accounts and added back Jane's annual salary of thirty-five thousand pounds, which she took as the working operator. Next, they added five thousand pounds for her personal mobile phone and vehicle insurance, which the business had covered. Finally, they added a one-off expense of four thousand pounds for emergency plumbing repairs that would not happen again. This brought the total SDE to sixty-nine thousand pounds. When potential buyers evaluated the business, they used the sixty-nine thousand pound figure rather than the twenty-five thousand pound net profit. This realistic reflection of earnings helped Jane secure a fair valuation and successfully sell the business within three months at a multiple of 2.5 times SDE.
Watch out
Common mistakes.
- Adding back the salaries of multiple working owners when the SDE formula only supports one full-time operator.
- Including routine maintenance costs as one-off expenses just to boost the profit figure artificially.
- Failing to provide proper receipts and documentation for personal expenses claimed as add-backs.
Questions
People also ask.
Why is SDE only used for small businesses?
SDE assumes the business is run by a single owner-operator who will step into the day-to-day management. Larger businesses are run by professional management teams, so EBITDA is used instead.
Can I add back the salary of an employee who does not work in the business?
No. You can only add back the wages of family members or non-working staff if you replace them with a market-rate employee or if their role is absorbed by the new owner.
How does SDE affect the final purchase price?
Buyers usually multiply the SDE by a specific industry factor to determine the business value. A higher verified SDE directly increases the asking price.
