Equity Injection: What It Means for Business Buyers

What Is Equity Injection?

The distinction between "equity injection" and "down payment" matters more than it sounds.

A down payment implies you pay cash out of pocket and the lender covers the rest. An equity injection is a capital adequacy test. The SBA wants to know that you have skin in the game and that the deal is not 100% leveraged. How you meet that 10% threshold is more flexible than most buyers realize.

The 10% is calculated on the total purchase price, not the loan amount. On a $500,000 acquisition, the equity injection is $50,000. On a $1,000,000 acquisition, it is $100,000.

What Counts as Equity Injection

The SBA accepts several sources toward the 10% equity injection requirement.

Cash. Buyer's own liquid funds. This is the most straightforward. Bank statements will document the source.

ROBS (Rollover as Business Startups) or 401(k) rollover. Retirement funds rolled into a C-corp that then invests in the business. This counts as equity, not a loan, because you are not borrowing money. There is a specific IRS-compliant structure required. Not every acquisition uses this, but it is a legitimate path.

Gifted funds. Cash gifts from family members, with proper documentation. The donor cannot be repaid, which the SBA verifies through a gift letter.

Seller note on full standby. This is the most commonly used piece of the structure. A seller note on full standby means the seller agrees to receive no payments during the SBA loan term, typically 10 years. Because the seller is not pulling cash out of the business during the loan period, the SBA treats this note as equity-equivalent rather than debt.

According to Regalis Capital's deal team, they achieve full standby seller notes at 0% interest on over 90% of their deals. This is the primary mechanism that lets buyers close acquisitions with only 5% cash out of pocket.

What Does NOT Count as Equity Injection

The SBA is specific about what it will not accept.

Borrowed money of any kind does not count. This includes personal loans, credit card advances, home equity lines of credit used as a "bridge," and loans from friends or family that must be repaid. The SBA will ask for 3 to 6 months of bank statements to verify that funds have been seasoned and are not the result of a recent large deposit from a loan.

Partially-on-standby seller notes do not count. The seller note must be on full standby. If the seller receives any payments during the SBA loan term, the note does not meet the equity-injection standard.

How the 5/5 Structure Works in Practice

The standard Regalis Capital deal structure looks like this:

• 70% to 85% SBA 7(a) loan
• 10% to 20% seller note on full standby
• 5% buyer cash equity injection
• 5% seller note on full standby acting as equity (separate from the seller financing piece above, or combined depending on deal size)

In practice, the seller note often serves two functions simultaneously: it fills the gap between the SBA loan and the purchase price, and the 5% standby portion counts toward the equity injection requirement.

The table below shows how this plays out at three different acquisition prices. These are illustrative examples based on current SBA deal structures as of Q1 2026.

These are rough estimates based on current market data. Actual terms depend on individual qualification, lender, and deal structure.

The $300,000 acquisition requires only $15,000 in cash from the buyer. The $1,000,000 acquisition requires $50,000 in cash. This is why SBA acquisitions are structurally different from buying real estate or raising private equity.

How Does Equity Injection Apply to SBA Acquisitions?

Based on Regalis Capital's analysis of recent acquisitions, the equity injection structure is the single most misunderstood element of SBA deal mechanics. Most first-time buyers assume they need to bring 20% to 30% cash to close. The 5% cash plus 5% standby seller note structure changes the math considerably.

Here is how the equity injection fits into a full deal stack at a $500,000 acquisition price:

The SBA lender provides $400,000 at approximately 10% to 11% interest on a 10-year term (based on current rates, which move with WSJ Prime). The seller agrees to a $75,000 note on full standby at 0% interest, with $25,000 of that note counting toward the equity injection requirement. The buyer brings $25,000 in cash.

Annual debt service on the $400,000 SBA loan at current rates runs approximately $62,000 to $65,000. For this structure to hit the target 2x DSCR, the business needs to generate roughly $124,000 to $130,000 in annual cash flow. At a 1.5x floor, the minimum acceptable cash flow is around $93,000 to $98,000.

The seller note on full standby adds no debt service pressure during the SBA loan term because no payments are made. This is why the full standby structure is not just convenient, it directly improves DSCR math.

Related Terms

Understanding equity injection requires knowing how it fits into the broader SBA deal structure.

SBA 7(a) Loan is the financing vehicle that the equity injection requirement applies to. The 10% injection is an SBA rule, not a lender preference.

Seller Note on Full Standby is the mechanism that lets buyers use a portion of the seller's deferred payment as equity. Understanding how standby works is essential before structuring any SBA deal.

DSCR (Debt Service Coverage Ratio) is directly affected by whether the seller note is on standby. A seller note with active payments increases debt service and reduces DSCR. Full standby removes those payments from the calculation entirely.

Frequently Asked Questions

Can a seller note on full standby replace all 10% of the equity injection requirement?

No. The SBA requires that at least 5% of the equity injection come from an eligible source other than a seller note. In practice, the standard structure is 5% buyer cash plus 5% seller note on full standby. The buyer must contribute some cash directly. A deal structured with zero buyer cash will not meet SBA equity injection standards.

Does the equity injection amount change if I am buying a partial stake in a business?

Yes. The equity injection is calculated based on the total acquisition cost, not the enterprise value. If you are buying 100% of a business for $750,000, the injection is $75,000. If you are buying a partial stake for $300,000, the injection is $30,000. The 10% rule applies to what you are paying, not what the whole business is worth.

What happens to the seller note acting as equity after the SBA loan is paid off?

The seller note becomes payable once it is no longer required to remain on standby. After the 10-year SBA loan term ends, the buyer and seller can negotiate repayment terms for the outstanding note balance. At 0% interest with no payments during the standby period, the note balance stays flat for the full term. This is one reason sellers sometimes push back on long standby periods, and why structuring this correctly from the start matters.
