TL;DR
An add-back is any expense a seller claims you won’t have once you take over the business. On paper, they boost SDE (Seller’s Discretionary Earnings) and make the deal look juicier. In reality, many are inflated, misleading, or outright fiction. Learn the five most abused categories, how they distort valuations, and how to rebuild a P&L to see the real numbers.
Understanding Add-Backs
If you’ve ever looked at a small business listing and thought:
"Wait, how is this guy making $400K from a doggy daycare?"
You’re probably looking at an add-back fiesta.x
Definition: Add-backs adjust net income to reflect the owner’s benefit. In theory, they strip out expenses you won’t have.
Reality: They’re also the #1 way brokers inflate valuations.
-
Examples in Theory:
- Personal car lease
- Annual ski trip passed off as a "conference"
- Grandma on payroll for answering the phone
-
Examples in Reality:
- Necessary salaries disguised as “discretionary”
- Marketing spend you’ll need to restart
- “One-time” repairs that happen every year
Operator Tip: If cutting the expense would hurt revenue, it’s not an add-back. It’s your new bill.
The 5 Most Abused Add-Back Categories
If there’s a broker playbook for inflating valuations, this is page one.
1. Owner’s Salary (or Lack of One)
- The Move: Add back the full salary because “you can choose to pay yourself whatever you want.”
- The Problem: Unless you work for free or clone yourself, you’ll need a replacement.
- Example: $75K owner salary added back, but you’ll hire a GM at $90K — not income, just payroll.
2. Family on Payroll
- The Move: Remove salaries for spouse, kids, or cousin Jimmy who “doesn’t really do anything.”
- The Problem: They probably do something you’ll have to replace.
- Example: $30K for admin work by seller’s spouse — you’ll need a bookkeeper or VA.
3. Personal Perks Disguised as Business Expenses
- The Move: Add back meals, travel, vehicles, phones — anything that smells personal.
- The Problem: Some of it is real business overhead.
- Example: $12K in travel “add-backs” includes supplier visits and a trade show — ops-critical.
4. Underreported Marketing Spend
- The Move: Call marketing “discretionary” or “paused” and add it back.
- The Problem: Leads don’t come from nowhere.
- Example: $15K add-back for “paused ads during COVID,” but now you’ll spend $20K/month to restart.
5. “One-Time” or “Non-Recurring” Expenses
- The Move: Add back lawsuits, repairs, upgrades — anything labeled one-off.
- The Problem: Many “one-time” costs happen… every time.
- Example: $8K “non-recurring” IT fixes — third year in a row.
How Add-Backs Inflate the Multiple
Here’s the math trick:
- Inflate SDE with add-backs
- Apply a multiple
- Market it as a “deal”
Example:
- Claimed SDE: $300,000
- Add-backs: $75K owner salary, $20K marketing, $15K “non-recurring” legal fees
- Asking Price: $900,000 → Claimed Multiple: 3x
- Reality: Real SDE ≈ $190,000 → Real Multiple: 4.74x
Line Item | Broker’s Version | Reality After Due Diligence |
---|---|---|
Owner Salary Add-Back | $75,000 — “You can pay yourself whatever you want.” | $90,000 cost to hire GM — no net gain. |
Marketing Add-Back | $20,000 — “Paused ads, totally optional.” | $240,000/year to maintain lead flow at current revenue. |
One-Time Legal Fees | $15,000 — “Won’t happen again.” | Annual compliance and dispute costs averaging $10,000/year. |
Claimed SDE | $300,000 | $190,000 |
Effective Multiple | 3.0× | 4.74× |
Operator Tip: Multiples don’t lie — inflated SDE does.
What to Accept — and What to Reject
Usually Acceptable:
- Personal car lease not used for business
- Health insurance if you’ll use your own
- Charitable donations unrelated to ops
- Documented one-time legal settlements
- Excess owner salary if you’ll replace them for less
Reject or Discount Heavily:
- Family salaries for people you’ll need to replace
- “One-time” costs that recur
- Marketing needed to sustain revenue
- Blended personal/ops expenses
- Owner salary add-backs when you’re taking their job
