You Don't Need $500K to Buy a Business (The Real Math on SBA Deal Sizing)

Most people think they need half a million dollars to buy a business. They see a listing for a million dollars, their brain does the math wrong, and they close the browser tab. They go back to their corporate job and tell themselves they'll do it someday when they have the money.

That math is wrong. And the people telling you that number have never closed an SBA deal.

We've closed hundreds of millions in deals. Many of those are SBA-financed acquisitions. We look at over 150 deals a week, every week. I'm not telling you theory. I'm telling you what I see.

In this post, I'm going to break down the real math on three deal sizes, walk you through two real closed deals, and show you exactly what it costs to get to the closing table with SBA 7(a) financing.

The Myth: Why Everyone Gets the Number Wrong

Here's what happens. You see a business listed for a million dollars. Your brain says you need a million dollars. Or you hear someone say you need 20 to 30% down, and you figure that's $200,000 to $300,000 just to get started.

So you walk away.

But SBA 7(a) financing exists specifically to make small business ownership accessible. The SBA will finance up to 90% of a deal when you structure it right. Layer in a seller note, and the buyer's cash at closing drops to just 5% of the purchase price.

5%. Not 50%. Not 30%. Five.

Brokers don't explain this math. Their job is to get you focused on the listing price and paying it. Lenders don't explain it either. Their job starts after you already have a deal, and they want as much of your cash in the transaction as they can get. And the people selling courses online? They've never structured a seller note in their life.

The Three-Part Formula Behind Every SBA Deal

Every SBA acquisition deal has three capital components. Understanding these is the entire game.

Part 1: Equity Injection. The SBA requires a minimum 10% equity injection on acquisition deals. But here's the key: that's total equity, not all your cash. That 10% can come from you, or it can come in part from the seller as a seller note.

Part 2: Seller Note. This is where the structure changes everything. We close almost every one of our deals with a 10-year full standby seller note at 0% interest. Full standby means the seller gets zero payments for 10 years, until the SBA loan is paid off. That's not a pipe dream. We negotiate almost every deal with those terms. If the seller carries a note for over 5% of the total deal on those terms, your cash at closing can drop to just 5%.

Part 3: Closing Costs. These sit on top of your equity injection. Legal fees, diligence costs, lender fees, the SBA guarantee fee, appraisals, environmental reports, and whatever else is applicable. Expect all these fees to land somewhere between 3 to 5% of your deal size. The important part? These costs can get rolled into the SBA loan. They're part of the total project cost.

The Number Nobody Talks About: Post-Close Liquidity

Your cash at the closing table is not the total capital you need. 5% gets you to the closing table. But you need 15 to 20% of the deal in total liquid capital.

The gap between 5% and 20% is post-close liquidity. The lender views this as your runway while you learn the business and operate. That post-close capital doesn't all have to be cash in your savings account. It can be a HELOC, a retirement account, stocks that can be made liquid, or cash surrender value on a life insurance policy.

A HELOC is the only acceptable debt instrument that counts as liquidity. I know some people love saying that 0% credit cards can get you there. That's not reality. Those actually make it worse.

Remember that 20% number. It's going to come back.

Deal Breakdown 1: The $1 Million Business

A million-dollar deal is the entry point for most first-time SBA buyers. Here's the full math.

Purchase price: $1,000,000. Closing costs at the high end run about $48,000 (legal and diligence at $14,000 to $20,000, SBA guarantee fee at $15,000 to $18,000, appraisals and environmental reports at $3,000 to $5,000, miscellaneous at $2,000 to $5,000). Those closing costs get rolled into the SBA loan as part of the total project cost.

Total project: about $1,048,000.

The SBA loan covers 85% of the total project. That's about $891,000. The seller carries a note for 10% of the purchase price, which is $100,000 on a 10-year full standby at 0% interest.

Your injection is 5% of the total project. About $52,000 cash at the closing table.

Not $500,000. Not $300,000. Not even $100,000. $52,000.

Post-close liquidity runs another $100,000 to $150,000. Remember, that doesn't all have to be cash. HELOCs, retirement accounts, stocks, and cash surrender value all count. Total capital needed: about $150,000 to $200,000.

For a sanity check, the monthly SBA payment on about $891,000 at current rates runs $11,000 to $12,000 a month. If SDE on this deal is $300,000 or more, your DSCR lands right around 2x. That's exactly where we target for comfort.

Real Deal: The NEMT Company

We closed a deal on a non-emergency medical transport company. Purchase price: $1,250,000. SBA loan: $1,062,500. Seller note: $125,000 on a 10-year full standby with zero payments. Three months of transition negotiated.

Buyer injection: $62,500. SDE: over $450,000 a year.

$62,500 in cash to buy a business producing over $450,000 a year in cash flow. That's not an outlier. This is what we see every single week.

Deal Breakdown 2: The $2.5 Million Business

Purchase price: $2,500,000. Closing costs run about $86,000 at this level and get rolled into the SBA loan. Total project: about $2,586,000.

SBA loan at 85%: about $2,198,000. Seller note at 10% of purchase price: $250,000. Ten-year full standby, 0% interest.

Cash at the closing table: about $129,000.

Post-close liquidity: $250,000 to $375,000 from the same sources. Total capital needed: about $375,000 to $500,000.

Real Deal: The Painting Contractor

We closed a deal on a 20-plus year old painting contractor. Purchase price: $1,850,000. SBA loan: $1,572,000. Seller note: $92,500 on a 10-year term at 7%. Operational manager already in place. Three months of transition negotiated.

Buyer injection: $185,000. SDE: $1,190,000. DSCR well above 2x.

Now, notice something on that deal. The seller note was at 7% interest, not zero. Not every seller agrees to full standby at zero. Some want interest. Some want a shorter term. When the seller note terms change, the buyer's cash requirement changes. But we close over 90% of our deals on full standby terms. It takes the right positioning and negotiation to get there.

Deal Breakdown 3: The $5 Million Business (SBA Maximizing)

$5,000,000 is the SBA 7(a) maximum. Here's the math near the top of the range.

Closing costs scale up to about $149,000 (legal and diligence at $35,000, SBA guarantee fee at $90,000, appraisals at $12,000, miscellaneous at $12,000). All rolled into the SBA loan.

Total project: about $5,149,000. SBA loan at 85%: about $4,377,000. Seller note at 10% of purchase price: $500,000. Ten-year full standby, 0% interest.

Cash at the closing table: about $257,000.

Even at the maximum SBA deal size, you're not writing a check for $5,000,000. Post-close liquidity at this level runs $500,000 to $750,000 from the same sources. Total capital needed: about $750,000 to $1,000,000.

The monthly SBA payment on $4,377,000 runs $55,000 to $58,000 a month. With SDE of $1,500,000, your DSCR lands right around 2x.

Flip It Around: Start With What You Have

Instead of starting with the deal size, start with what you have. This is the question everyone asks: "What can I buy with what I have?"

Here's the reverse framework:

• $150,000 to $200,000 in total capital gets you to a $1,000,000 deal. That's about $52,000 cash at closing, plus post-close liquidity from the sources we covered.

• $375,000 to $500,000 in total capital gets you to a $2,500,000 deal. Cash at closing is only about $129,000.

• $750,000 to $1,000,000 in total capital gets you to the $5,000,000 SBA max. Cash at closing is about $257,000.

If you're lighter on liquidity, stretch cases work. We closed a deal on a commercial printing business producing $323,000 a year in cash flow. Structured as 85% SBA, 15% seller finance, with three months of working capital included. Bought at 2.17x SDE. The buyer was lighter on liquidity but had strong operational experience. That deal closed.

Your liquidity determines your deal size. Not the other way around.

The Real Barrier Isn't Cash

The real barrier to buying a business isn't how much money you have in the bank. It's knowing how the math works. Start with what you have. Work the formula backward. You'll know exactly what you can buy.

You can do all of this yourself. Some people do. But if you want a team that does this every single day handling it for you, we can help.
