Add-Backs Made Easy: Understanding Seller Discretionary Earnings (SDE) When Selling Your Business

This guide will explain what add-backs are, why they matter, and how they affect your business value. By the end, you’ll know exactly what buyers look for and how to prepare long before you sell.

What are add-backs?

When someone buys a small business, they want to know one big thing: “How much money does this business really make for the owner?”

This number is called Seller Discretionary Earnings (SDE) or the total financial benefit the owner takes home each year. But your tax return or profit-and-loss statement does not always show the full picture.

Why? Because most small business owners run personal or one-time expenses through the business. These lower your taxes, but they also make the business look less profitable than it really is.

Add-backs fix that. They “add back” expenses that a future buyer would not have to pay, so the buyer can see the true earning power of your business.

‍

Why do add-backs matter?

Add-backs directly affect:

✔ How much your business is worth

Higher SDE = Higher valuation = Higher sale price.

✔ How attractive your business is to buyers

Buyers want clean, clear numbers. Add-backs help tell the real story.

✔ Your negotiation power

If you can explain your add-backs well, buyers will trust your financials more.

‍

Examples of add-backs:

Here are the most common add-backs buyers look for. You may have many of these without realizing it.

1. Your salary (aka owner’s compensation)

Most buyers will replace you with themselves or someone else, so your salary is usually added back.

Example:
You pay yourself $80,000/year.
Add-back: $80,000

2. One-time or non-recurring expenses

Things that won’t happen again or are unusual for a normal year.

Examples:

• Legal fees from a dispute
• A one-time website rebuild
• Equipment repair after a storm
• Rebranding or special consulting project

Example:
You paid $12,000 one year to defend a lawsuit.
This will not repeat → Add-back: $12,000

3. Personal expenses run through the business

Very common for small businesses...and totally normal. Don't worry!

Examples:

• Your personal car payment
• Family cell phone plans
• Personal travel mixed with a conference
• Personal meals or entertainment
• Your kids on payroll (buyers love this example!)

Tip:
You don’t need to feel embarrassed. Buyers expect this.

4. Family members on payroll (who won’t work for the buyer)

If your spouse or child helps a little — or not at all — their pay may be added back.

Example:
You pay your teenage daughter $10,000/year to help with admin tasks.
Add-back: $10,000

5. Owner’s benefits or perks

Expenses a buyer won’t need to pay for.

Examples:

• Health insurance for you
• Retirement contributions
• Gym memberships
• Personal subscriptions
• Travel upgrades (first-class flights, nicer hotels)

6. Interest expenses

Interest payments are tied to your debt, not the buyer’s.
Buyers will have their own financing.

So interest gets added back.

7. Depreciation and amortization

These are accounting rules, not real cash flowing out. They always get added back to calculate SDE.

8. Unusual COVID expenses (still common in valuations)

If your business had one-time costs or income changes due to COVID, they may qualify.

Examples:

• Deep cleaning
• Special PPE
• Temporary shutdown costs
• One-time government grants

Example: add-backs in action

Let’s say your Profit & Loss statement shows a net income of: $80,000

But after reviewing add-backs, we find:

Owner salary: $60,000
Personal vehicle: $6,000
One-time legal fees: $8,000
Depreciation: $10,000
Health insurance: $7,000

Total Add-Backs = $91,000

Now we calculate SDE:

$80,000 (net income)

• $91,000 (add-backs)
  = $171,000 SDE

A buyer values your business using multiples of SDE.

If your industry multiplier is around 2.5x, then:

👉 $171,000 x 2.5 = $427,500 value

Without add-backs, your business looks like it's worth ~$200k. With add-backs, it’s worth more than double.

This is why add-backs matter.

‍

What owners often get wrong about add-backs:

Here are common mistakes:

❌ Thinking add-backs are “cheating”

They’re not — they’re standard.

❌ Not documenting add-backs

Buyers need proof (invoices, notes, an expense summary).

❌ Waiting until they’re ready to sell

Start tracking add-backs now, even if you’re years away.

❌ Overstating add-backs

Don’t try to add back things that are truly business expenses (rent, labor, cost of goods). Buyers will walk away if numbers seem inflated.

‍

How to track add-backs (the easy way)

You don’t need fancy tools. Owners can:

✔ Keep a simple spreadsheet
✔ Label personal or one-time expenses in QuickBooks
✔ Write notes on unusual expenses
✔ Save invoices for anything you want to add back
✔ Review add-backs annually

And if you're an SMB.co owner, this will all become even easier with our valuation tools and dashboards.

Why seller discretionary earnings (SDE) matters most:

SDE is the number buyers use to decide:

• What your business is worth
• Whether they can get an SBA loan
• Whether they can pay themselves
• Whether the business fits their financial goals

Most small businesses (under $5M revenue) are valued based on SDE, not revenue.

So cleaning up your SDE with proper add-backs can increase your sale price significantly.

‍

Final takeaway for owners:

Add-backs are not just an accounting term, they are a powerful tool that:

✔ Shows the true earning power of your business
✔ Helps buyers understand your numbers
✔ Raises your valuation
✔ Makes your business more attractive
✔ Gives you confidence when you’re ready to sell

And the best part? You can start preparing years in advance.
