SBA Equity Injection Explained: 5% Cash + 5% Seller Note Structure

What Is an SBA Equity Injection and Why Does It Matter?

The SBA does not call it a down payment. That distinction is not semantic. It matters because equity injection has specific rules about what qualifies, what does not, and how it can be structured. Getting this wrong is one of the most common reasons deals fall apart at the lender stage.

Every SBA 7(a) acquisition loan requires the borrower to inject at least 10% equity into the transaction. The purpose is to ensure the buyer has skin in the game and that the business is not being acquired with 100% borrowed money.

The critical word is "injection." The SBA cares that real economic value is going into the deal from a source that is not a loan. Cash qualifies. A seller note on full standby qualifies. Borrowed money from anywhere does not.

What Counts as SBA Equity Injection?

Not all sources of funds are treated equally. The SBA draws a hard line between equity and debt. Here is what qualifies.

Cash from the buyer. Personal savings, checking, money market, or any liquid asset the buyer owns free and clear. The lender will verify the source with 60 to 90 days of bank statements. The cash must be seasoned, meaning it cannot arrive as a large unexplained deposit right before closing.

Seller note on full standby. This is the most deal-friendly component of the structure. A portion of the seller's proceeds gets deferred, structured as a promissory note at 0% interest with no payments during the entire SBA loan term (typically 10 years). Because the seller is leaving money in the deal without expecting repayment during the loan period, the SBA treats this as equity-equivalent. Regalis Capital achieves full standby terms on over 90% of transactions.

Retirement funds via ROBS. A Rollover for Business Startups (ROBS) allows a buyer to roll funds from a 401(k) or IRA into a C-corporation that then invests in the acquisition. Done correctly, this is not a distribution or a loan, so it does not trigger early withdrawal penalties. It counts as equity. ROBS is complex and requires a specialist to set up properly. Costs typically run $5,000 to $10,000 in setup fees, with ongoing administration around $1,500 to $2,500 per year.

Gifted funds with documentation. A family member or third party can gift funds for the equity injection. The gift must be documented with a letter confirming no repayment is expected. The lender will scrutinize gifted funds carefully. The gift giver may also need to provide their own bank statements showing the source of the gift.

Equity from a sold asset. Proceeds from selling real estate, stocks, or other assets can fund the equity injection, as long as the source is documented and verifiable.

What Does NOT Count as Equity Injection?

This is where buyers get into trouble.

Borrowed money. Any loan taken out to fund the equity injection is a disqualifier. This includes personal loans, home equity lines of credit (HELOCs) taken out specifically for this purpose, and loans from friends or family with repayment expectations.

Credit card advances. Cash advances on credit cards are debt, not equity. Lenders see this and it kills deals.

Unsecured personal loans. Same logic as above. If there is a repayment obligation, it is not equity.

Seller notes NOT on full standby. A seller note that requires payments during the SBA loan term does not count as equity. The note must be on full standby, meaning zero payments for the duration of the SBA loan, to qualify. This is a common misunderstanding. A seller carrying back 10% with monthly payments is not an equity injection structure.

Investor money with equity or repayment expectations. If a third party is contributing funds in exchange for an ownership stake or repayment, the SBA will treat this as a co-borrower situation and potentially require that party to guarantee the loan as well. This complicates deals significantly.

How the 5% Cash + 5% Seller Note Structure Works in Practice

The standard Regalis Capital deal structure for SBA acquisitions works as follows.

The buyer brings 5% of the purchase price in cash to closing. The seller agrees to defer 5% of their proceeds as a promissory note with no interest and no payments for the duration of the SBA loan term (10 years). The remaining 80% to 85% of the purchase price is funded by the SBA 7(a) loan. Any gap between the SBA loan and the total deal value is typically covered by additional seller financing at market rate, separate from the standby equity note.

The seller is not giving away money. They receive 95% of the purchase price at closing (or close to it, after accounting for the seller note), and they receive the deferred 5% at the end of the SBA loan term or upon a sale of the business, whichever comes first.

From the seller's perspective, accepting a standby note is often preferable to a deal falling apart. Regalis Capital's team works with sellers to frame this accurately: they are deferring a small portion of their proceeds, not forfeiting them.

From the buyer's perspective, this structure minimizes cash out of pocket at closing. Rather than needing 10% cash, the buyer only needs 5%.

Deal Math: Three Acquisition Scenarios

The following tables show exact equity injection requirements across three deal sizes. These are estimates based on current market data as of Q1 2026. Actual terms depend on individual qualification and lender.

Scenario 1: $300K Acquisition

At $300K, the buyer needs $15,000 in cash. That is a realistic number for many first-time buyers.

Scenario 2: $750K Acquisition

At $750K, the buyer needs $37,500 in cash. The additional seller note at market rate is separate from the standby equity note. These are rough estimates based on Q1 2026 market data.

Scenario 3: $1.5M Acquisition

At $1.5M, the buyer needs $75,000 in cash. That is a manageable number for a business generating $400K in annual cash flow, particularly when paired with ROBS or retirement funds for buyers who are cash-constrained. These are rough estimates based on Q1 2026 market data. Actual terms depend on individual qualification and lender.

Note on SDE: the cash flow figures above represent discounted SDE. SDE (Seller's Discretionary Earnings) is a broker-reported figure that typically requires a 15% to 50% discount to approximate what a buyer will actually take home after replacing the owner's labor.

What If You Do Not Have the 5% Cash?

This is a real situation. Not every qualified buyer has $37,500 or $75,000 sitting in a checking account. Here are the legitimate options.

ROBS (Rollover for Business Startups). If you have retirement savings in a 401(k), 403(b), or IRA, ROBS allows you to access those funds without a taxable distribution or early withdrawal penalty. The structure involves creating a C-corporation that sponsors a new qualified retirement plan, rolling the old retirement funds into the new plan, and then having the new plan purchase stock in the C-corp, which uses the proceeds for the acquisition. This is legal and IRS-recognized. It is also complex. Expect $5,000 to $10,000 in setup costs and annual administration fees. The key benefit: funds deployed via ROBS count as equity.

Increase the seller note. If the seller is willing to carry more than 5% on full standby, the buyer's cash requirement drops. Some sellers will carry 10% on full standby, reducing the buyer's cash injection to nearly zero. This requires lender approval and is not guaranteed, but Regalis Capital has structured zero-cash-at-closing deals on qualifying acquisitions.

Negotiate a lower purchase price. A lower price reduces the absolute dollar amount of the equity injection. If a deal is priced at $750K but the business is worth $650K, closing that gap also reduces your cash requirement by $5,000 (5% of $100K).

Equity partner. A passive equity partner who contributes cash without expecting repayment can provide the equity injection. The SBA will require the equity partner to also guarantee the loan if they own 20% or more of the entity. Ownership stakes below 20% do not trigger the personal guarantee requirement, but this should be structured carefully with legal counsel.

How the Seller Note on Full Standby Gets Documented

The standby seller note is a promissory note between the buyer (or the acquiring entity) and the seller. It specifies the principal amount, a 0% interest rate, and a payment schedule that begins after the SBA loan is fully paid off (or at year 10, whichever comes first). The SBA lender will require the seller to sign a standby agreement confirming they will not receive any payments during the standby period.

This is not a handshake deal. The documentation needs to be airtight. Regalis Capital's team works with transaction attorneys to make sure the standby note is structured in a way the SBA lender will accept. A poorly drafted seller note is one of the most common reasons SBA deals get delayed or restructured at the 11th hour.

According to Regalis Capital's deal team, sellers who initially resist the standby note concept almost always come around once they understand the alternative: the deal may not close at all without it. A 10-year deferral on 5% of the sale price is a small price for a seller who wants liquidity on the other 95% at closing.

Understanding the Full Acquisition Capital Stack

The SBA 7(a) loan does not have to be the only layer of financing. In a typical Regalis Capital deal structure, the capital stack looks like this.

SBA 7(a) loan: 70% to 85% of the purchase price. 10-year term. Rates currently approximately 10% to 11% based on WSJ Prime plus 1.5% to 2.75%.

Seller note (standby equity portion): 5% on full standby at 0% interest. Counts as equity.

Seller note (additional carry, if needed): 5% to 15% at market rate, with payments typically deferred for 6 to 24 months after closing. This portion is not part of the equity injection. It is subordinate debt that supplements the SBA loan.

Buyer cash equity injection: 5%.

Understanding how these layers interact is the foundation of SBA acquisition financing. See the equity injection glossary page for formal definitions, and use the acquisition calculator to model your specific deal.

The debt service coverage ratio (DSCR) is the metric that determines whether the full capital stack is serviceable. Regalis Capital targets a 2.0x DSCR at minimum, with a floor of 1.5x when synergies are credibly underwritten. At 1.25x, the deal does not pencil regardless of how the equity is structured.

When the Equity Injection Gets Complicated

A few situations require extra attention.

Partial cash, partial ROBS. If the buyer is funding part of the equity with cash and part via ROBS, the lender needs documentation from both sources. The ROBS administrator will provide a letter confirming the fund transfer. Both sources are counted together toward the 10% requirement.

Multiple buyers. If two partners are buying a business together, their combined equity injection still needs to hit 10%. The split between them is flexible, but the lender will verify the source of each person's contribution independently.

Business assets as equity. In some cases, a buyer may be contributing equipment or other assets rather than cash. The SBA allows this in specific circumstances, but the assets must be appraised and the value must be verified by the lender. This is less common in pure business acquisitions and more relevant in asset-heavy deals with real estate or heavy equipment.

Standby note with a balloon. Some sellers will accept a standby structure but want a balloon payment at year 5 rather than year 10. Depending on the lender, this may or may not qualify as a full standby note. The safer structure from an SBA compliance standpoint is a note that runs the full term of the SBA loan.

Frequently Asked Questions

What is the minimum equity injection required for an SBA 7(a) acquisition loan?

The minimum equity injection is 10% of the total acquisition price. This is not the same as a down payment. It represents capital from non-borrowed sources that goes into the deal. The standard structure is 5% buyer cash plus a 5% seller note on full standby at 0% interest, with no payments during the SBA loan term.

Can I use a home equity line of credit to fund my SBA equity injection?

No. A HELOC is a loan. The SBA requires equity injection funds to come from non-borrowed sources. Using HELOC proceeds for the injection will disqualify that portion of the funds and may kill the deal entirely. Acceptable sources include cash savings, retirement funds via ROBS, gifted funds with a gift letter, and seller notes on full standby.

What does "full standby" mean on a seller note?

Full standby means the seller receives zero payments on their note for the entire duration of the SBA loan term, which is typically 10 years. No interest accrues. No principal payments are made. The seller receives their deferred amount either at the end of the term or upon a sale or refinancing of the business. Regalis Capital achieves full standby terms on over 90% of transactions.

How does ROBS work for SBA equity injection?

A ROBS (Rollover for Business Startups) allows a buyer to roll funds from a qualified retirement account, such as a 401(k) or IRA, into a new C-corporation that invests in the acquisition. Because the funds are invested rather than withdrawn, no early withdrawal penalty or immediate income tax applies. The invested funds count as equity for SBA purposes. Setup typically costs $5,000 to $10,000 with ongoing annual fees of $1,500 to $2,500.

Can the seller contribute more than 5% on full standby to reduce my cash requirement?

Yes, and this is a legitimate strategy for cash-constrained buyers. If the seller carries 10% on full standby, the buyer's cash injection requirement drops to near zero on the equity portion. Lender approval is required. Some lenders are more flexible than others on the split, and the total equity injection (seller note plus buyer cash) still must reach 10%. Regalis Capital has structured zero-cash-at-closing deals on qualifying transactions.

Does a gift from a family member count toward the equity injection?

Yes, provided the gift is properly documented. The donor must provide a signed gift letter confirming no repayment is expected, and the lender will typically request bank statements from the donor showing the source of the gifted funds. Undocumented transfers between family members are treated as loans by SBA lenders until proven otherwise.

What happens to the seller note if I sell the business before the SBA loan term ends?

The standby seller note typically becomes payable upon a change of ownership or refinancing of the SBA loan, whichever comes first. This means if you sell the business in year 4, the seller receives their deferred amount at that closing. The exact terms depend on how the note is drafted, which is why having a transaction attorney involved in the documentation is non-negotiable.

At what acquisition price does the 5% cash requirement become too large for SBA 7(a)?

The SBA 7(a) loan maximum is $5M. At a $5M acquisition, the buyer cash injection at 5% would be $250,000. Most buyers targeting the upper end of the SBA range either use ROBS to supplement their cash or structure a larger seller note on standby. Regalis Capital focuses on deals in the $500K to $5M range, and the equity injection structure scales linearly across that range.
