There is a version of this conversation that starts with “save as much as you can and then we will figure it out.” That is the wrong version.

With an SBA 7(a) loan, the minimum cash you need to close on a business acquisition is 10% of the purchase price. On a $1M deal, that is $100K. On a $500K deal, $50K. That number is real, it comes straight from SBA requirements, and it is the floor most lenders work from.

But knowing the floor is not the same as knowing what you actually need in your account before you start a serious search. How much cash you need, where it can come from, how lenders verify it, and how a well-structured seller note changes the entire equation: that is what separates buyers who close from buyers who spend a year spinning.

The 10% Equity Injection: Floor, Not Target

The SBA 7(a) program requires a minimum 10% equity injection on any acquisition. On a $2M deal, that is $200K. On a $750K deal, $75K.

Some deals require more. Startup franchises, businesses heavy on goodwill with no hard assets behind it, or deals where the lender’s credit committee flags elevated risk can push the requirement to 15% or even 20%. But for a standard profitable business acquisition with reasonable structure, 10% is where most deals land.

One thing buyers consistently get wrong: they think the 10% is just a down payment. It is not exactly that. It is an equity injection. The distinction matters because the lender is not simply collecting a deposit. They are verifying that you have genuine skin in the game before they put up the remaining 90%. The sourcing, the seasoning, the documentation around those funds all matter as much as the number itself.

The SBA caps its loan at $5M, which means the program works for acquisitions up to roughly $5.5M depending on structure. Most of the deals we work on fall between $500K and $5M in acquisition price, mapping directly to this program.

What Actually Counts as Your Equity Injection

This is where most first-time buyers are surprised. Your cash savings for a business purchase do not have to sit in a single checking account waiting to be wired.

Sources that SBA lenders accept:

  • Personal cash savings in checking, savings, or money market accounts
  • 401(k) or IRA funds via a ROBS (Rollover for Business Startups) structure, without triggering early withdrawal penalties
  • Home equity through a HELOC or home equity loan, used to inject funds at closing
  • Gifted funds from family, with proper gift letter documentation and evidence the money is not a loan
  • Proceeds from selling another asset, such as a vehicle, real estate, or an investment account

What lenders will not accept: borrowed funds that create a new liability. A personal loan, a credit card advance, a margin loan against your brokerage account. If you are planning to borrow your equity injection, lenders will catch it. And it will kill the deal.

The key test is simple. Does the equity injection genuinely reduce the lender’s exposure? That is the whole point. If the money traces back to a new debt obligation, it fails that test.

How a Seller Note Changes the Cash Math

Here is something that significantly changes the cash savings equation, and most buyers do not hear about it until they are already deep into a deal.

In the majority of transactions we close, the seller carries a portion of the purchase price in the form of a seller note. When structured correctly (and this is the part that matters), that seller note can count toward your equity injection.

Our standard structure: a 10-year full standby seller note at 0% interest, typically representing 10% of the purchase price. Zero interest. Zero payments. For 10 years. The SBA lender funds 80%, the seller carries 10% in standby, and the buyer injects 10% in cash.

We achieve this structure on over 90% of our deals. It is not magic, and it is not the seller being generous out of the goodness of their heart. It requires negotiating the seller note properly from the outset, before the LOI is signed, and it requires a lender who understands and approves the structure before you go under contract.

On a $1M deal, that means you may only need $100K in actual cash savings. The seller’s $100K standby note handles the other portion of the equity requirement.

So if you are calculating your cash savings for a business purchase without factoring in a seller note, you are almost certainly overestimating what you need out of pocket. But do not assume the seller note is automatic. A 0% standby seller note is a negotiation outcome, not a default. Without proper advisory guidance, many sellers and their brokers push back hard on full standby terms.

Lender Verification: What They Actually Look At

Every SBA lender will verify your equity injection before they issue a commitment letter. No exceptions. Understanding this process early prevents the kind of last-minute surprises that blow up timelines.

Sourcing and seasoning. Lenders want to see that your funds have been sitting in an account for at least 60 days. If $200K shows up in your account two weeks before closing, expect questions. Expect documentation requests. Expect delays. The 60-day seasoning period exists because lenders are trying to confirm the money is genuinely yours, not a hidden loan from a friend or family member that you plan to repay quietly after closing.

Bank statements. Typically the last 2 to 3 months of statements for every account you are using. They are looking for large, unexplained deposits. A $30K deposit three weeks ago with no paper trail? That is a red flag, and you will need to explain it.

Paper trail for transfers. If money moved from a 401(k) through a ROBS, or came from the sale of an asset, you need documentation showing exactly where it originated and how it arrived in your account.

Gift documentation. If any portion came from family, the gift letter must state explicitly that it is a gift, not a loan, and must include evidence that the donor had the funds to give. Lenders have seen every creative workaround, and they are not fooled by vague letters.

Start gathering your documentation early. Sixty days before you engage a lender is not too soon. Waiting until the lender asks for it adds weeks to your timeline at the worst possible moment.

All of That Covers the Equity Injection. But That Is Not Your Full Number.

The 10% requirement is the floor for one component. Your actual cash savings for a business purchase should account for substantially more than just the equity injection.

Here is a realistic breakdown for a $1.5M acquisition:

  • Equity injection (10%): $150K
  • Closing costs: $15K to $25K (SBA guarantee fee, lender fees, legal, third-party reports)
  • Working capital reserve: $50K to $75K for operating the business in the first 90 days
  • Contingency: $25K to $50K

Total realistic cash position before starting a search in the $1M to $2M range: somewhere around $250K to $300K.

Side note: the SBA guarantee fee alone runs 3.5% of the guaranteed portion of the loan. On a $900K SBA loan, that is roughly $31,500. Buyers who budget only for the equity injection often come up short on cash to close, and by that point, the deal is already under contract and the pressure is on.

That $250K to $300K number does not mean every buyer needs exactly that. A seller note, a HELOC, or a business with strong working capital baked into the deal structure can shift things. But walking into a search with $100K in savings and targeting $1.5M businesses is a setup for frustration.

Know your real number before you start.

Cash Savings vs. Deal Size: Finding Your Search Range

Here is a simple way to think about this. Take your liquid savings, subtract a buffer for closing costs and working capital, and divide by 10%. That gives you a rough ceiling for the acquisition price you can realistically target.

Say you have $200K in liquid assets. Subtract $50K for closing costs and working capital reserve. That leaves $150K for equity injection. Divide by 10%. Your effective deal ceiling is $1.5M.

That is your search range. Not a wish. A number.

Targeting deals significantly above that number without a clear plan for additional equity sources will waste your time and burn goodwill with sellers and brokers. On the flip side, if you have $400K in liquid assets, you are realistically looking at businesses up to $3M to $3.5M, which puts a much wider and more attractive pool of deals in play.

Most buyers we work with are in the $150K to $500K cash position range, give or take. That covers the $1M to $5M deal range where the SBA program works best and where quality, cash-flowing businesses are consistently available.

Mistakes That Kill Equity Injection Timelines

Counting funds that are not truly liquid. A 401(k) is not liquid until it goes through a ROBS or gets distributed. Home equity is not liquid until you open a HELOC and draw on it. Restricted stock, illiquid real estate, and locked-up investments do not count until you can show the actual cash in an account. Telling a lender “I have $300K in equity in my house” is not the same as having $300K.

Moving money right before applying. If you consolidate accounts, sell investments, or transfer funds from a family member right before engaging a lender, it creates a paper trail problem. Do it early. Give it 60 to 90 days to season. This is one of those things that looks straightforward on paper but causes real headaches in practice.

Underestimating closing costs. Already covered the SBA guarantee fee above, but it bears repeating because we have watched buyers trip on this more than once. Budget for it. Budget for legal fees. Budget for the QoE report if the lender requires one.

Assuming the seller note structure is a given. We covered this, but it matters enough to say twice. The 0% standby seller note that reduces your cash out of pocket to 5% to 10% is a negotiation win, not a starting position that every seller agrees to.

Getting the equity injection right from the start keeps deals on track. Getting it wrong means renegotiating under pressure or losing the deal entirely.

Frequently Asked Questions

How much cash do you need to buy a business with an SBA loan?

The minimum is 10% of the purchase price as an equity injection. On a $1M acquisition, that is $100K. Add $15K to $25K for closing costs and 1 to 3 months of working capital reserves on top of that. Realistically, plan for 15% to 20% of the purchase price in total liquid assets before you begin a serious search.

Can the seller note count as part of the equity injection for an SBA 7(a) loan?

Yes, in many cases. A seller note on full standby, meaning no payments during the SBA loan term, can count as equity injection. This effectively reduces the cash you need at closing. The structure requires lender approval and careful negotiation well before the LOI stage. We structure deals this way on the majority of our transactions.

What counts as acceptable cash savings for a business purchase under SBA guidelines?

Acceptable sources include personal bank accounts, 401(k) funds through a ROBS structure, HELOC proceeds, proceeds from asset sales, and gifted funds with proper documentation. What does not count: any borrowed funds creating a new liability, including personal loans or credit card advances. Lenders verify sourcing through 60 to 90 days of account statements.

How do lenders verify equity injection for an SBA acquisition loan?

Lenders require 2 to 3 months of bank statements for every account being used. They look for unexplained large deposits that could indicate a hidden loan. Recently moved funds need a full paper trail. ROBS transactions, gift funds, and asset sale proceeds each carry specific documentation requirements that must be satisfied before the lender issues a commitment letter.

Does the 10% equity injection requirement ever increase?

Yes. Lenders may require 15% to 20% if the deal involves a startup franchise, has significant intangible goodwill without hard asset backing, or if the buyer’s financial profile presents higher risk. The 10% floor applies to standard profitable business acquisitions with reasonable deal structure. Your specific lender’s credit policy determines the final number.
