Let’s start with the question everyone asks – but no one answers well:

“What size business should I buy?”

Seems like a simple question. But it’s loaded with complexity, especially once you introduce leverage. The moment you bring debt into the equation (which, let’s be honest, you will), the stakes go up fast.

Now you’re not just buying a business. You’re buying pressure. And if you’re not careful, you’re buying a future you’re not ready for.

You’ll see soon enough that: the size of the business you buy is directly tied to the amount of risk you’re agreeing to shoulder.

So let’s walk through how to think about this. Because “bigger is better” is only true when you understand the tradeoffs.

This breakdown comes from Chelsea Wood, my co-founder at Acquisition Lab. She’s seen hundreds of buyers go through the process. She’s guided them through the fog of indecision, helped them navigate SBA underwriting, and has probably answered this one question more times than she’d care to count.

Here’s what you need to know.

 

The Size Fallacy: “I Should’ve Bought Bigger”

It’s a badge of honor in the search world to say, “I should’ve bought bigger.”

It sounds bold. Aspirational. Sophisticated, even.

But that’s a hindsight luxury. And survivorship bias is real.

Yes, it’s true that whether you buy a $1M or a $5M business, the search process and transition pain are remarkably similar. But that doesn’t mean everyone should swing for the fences.

In the moment – when the deal’s on the table, the bank wants your tax returns, your wife’s asking why your stress-induced eye twitch is back, and your kid needs braces – it doesn’t feel like you should be going bigger. It feels like you’re already pushing the limits.

 

 

Bigger deals come with lower execution risk – but much higher financial risk. Smaller deals have the opposite profile.

So what kind of risk are you comfortable with?

If you hate debt and it keeps you up at night, buying a $5M business with a $4.5M SBA loan might not be a wise move – regardless of what Twitter bros say.

 

Execution Risk vs. Financial Risk

Think of it like this:

• Small deals (<$1M) are often owner-operated with limited infrastructure. You’ll work harder and carry the business on your back. Low financial risk, but high execution risk. In smaller deals, you’re the engine.
• Larger deals ($5M–$20M) often come with managers, SOPs, and mature systems. You won’t need to reinvent the wheel – but you’ll owe a lot more. Lower execution risk, but the financial risk is real. In larger deals, you’re the guarantor.

You need to decide: What kind of risk keeps you up at night?

 

Rule of Thumb: Cut Earnings in Half

Let’s say you’re eyeing a business with $450K in SDE.

Sounds solid, right?

Now subtract loan payments.
Now set aside reserves.
Now account for variability in monthly cash flow.
Now consider the ramp time before you’re even operating at full speed.

Suddenly that $450K starts to look a lot more like $225K. And that’s before funding growth initiatives, rebuilding working capital, hiring an operator, or paying yourself.

If you’re trying to replace a $200K salary with $450K SDE, you’re probably going to be underwater.

 

 

Here’s a good rule of thumb as you’re on your search: Cut earnings in at least half to determine your realistic salary. 

If you want to pay yourself $100K, target $300K–$400K SDE to be safe. To pay yourself $200K? You need $600K–$800K, minimum.

And if you want to hire an operator or build aggressively? Think even bigger.

Remember: The math only works if the earnings support the plan.

If you’re planning to:

• Replace your $200K income
• Spend $50K/year on growth
• Set aside $30K in cushion

That’s $280K you’ll need after debt service.

So if debt service eats 50–60% of SDE, you’re going to need $600K–$700K in SDE minimum to make the model work.

This is where so many buyers get tripped up: they target too low and assume the earnings will support their vision. They won’t.

 

Can You Actually Afford This?

Don’t just ask “How much can I buy?”

Ask:  How much can I buy and still sleep at night?

The cost of a business isn’t just the purchase price. You need capital for:

• The down payment (SBA will require 10–20% equity in the deal – don’t get cute).
• Post-close liquidity (5–15% of loan value, depending on the bank).
• Your own personal runway (aka not freaking out in month 3 when payroll hits and your distribution doesn’t).

As Chelsea said, “It’s one thing to close. It’s another thing to survive the first 6 months.” Especially if you’re relying on that cash flow to live.

Don’t just model the down payment – model the entire capital stack.

 

Be Real About the Risk of Hiring an Operator

One of the most dangerous ideas floating around right now is the “I’ll just hire an operator” plan.

Do not buy a business and immediately hand it off to a stranger from LinkedIn.

Doing this is a great way to lose your money – and your mind. It’s not that strangers on LinkedIn don’t have good intentions – it’s that operators don’t work miracles. Ultimately, if you don’t know the business yet, you can’t lead, manage, or spot a bad decision within the business until it’s too late.

Might I also remind you that the debt you just took on was personally guaranteed? Not worth the risk.

However, if you want to step back from the business in 18–36 months? Great. That’s a smart long-term play. But know the business first. Then hire.

 

Yes, SBA Is Getting More Flexible – But Don’t Abuse It

As of June 1, 2025, new SBA rule changes have significantly reshaped how deals can be structured and what’s still allowed.

• Seller notes that are specifically used toward your equity injection now require full 10-year standby (no payments for a decade).
• Any retained seller equity triggers a personal guarantee from the seller — the guarantee may be limited.
• Outside equity capital must come from U.S. citizens or permanent residents. No foreign capital is allowed in the equity stack.

But be warned: just because you can get a deal financed doesn’t mean you should.

If four lenders turn you down and one says yes, that’s not a green light – it’s a red flag.

 

 

Don’t use the new rules as permission to overextend. Use them as a tool to close good deals more efficiently.

 

So… What Size Business Should You Buy?

The real answer?

The biggest business your capital, life goals, and psychological bandwidth can support.

Ask yourself:

• How much cash do I actually have access to?
• How much debt can I emotionally stomach?
• Am I trying to replace income? Hire? Build?
• Am I okay being the operator for a year or two?
• What kind of risk keeps me up at night – financial or operational?

That’s how you decide.

Not with Twitter threads.
Not with LinkedIn humblebrags.
Not with hindsight bias.
Not with “I should’ve gone bigger” stories from people who conveniently forgot their panic attacks.

This is your risk, your capital, your life. Own it.
