Equity injection calculator
Equity injection calculator (10%)
Enter your total project cost to estimate the 10% SBA equity injection, then model how much could be satisfied by seller debt on full standby (capped at 50% of the injection).
If you plan to use a personal loan (including a HELOC) to fund part of the injection, repayment generally must be documented as coming from a source other than the acquired business's cash flow.
Buying a business with an SBA 7(a) loan requires a minimum 10% equity injection of the total project cost in nearly every scenario—first-time acquisitions, owner buyouts, business expansions, and ESOP purchases alike. This requirement is addressed in SBA SOP 50 10 credit standards for 7(a) changes of ownership.
The three ways to fund your 10%
SBA doesn't require all 10% in cash from your own bank account. Acceptable sources generally fall into two buckets:
Unlimited sources (can cover the entire 10%)
- Cash that isn't borrowed, from the business or elsewhere
- Cash from a personal loan, as long as repayment comes from something other than the business's cash flow(salary paid from the acquired business generally doesn't count)
- Grants with no repayment or clawback conditions during the loan term
Limited sources (can cover no more than half)
- Standby seller debt (full standby for the loan term)
- Non-controlling minority equity investors (typically under 20% ownership, no operational control)
When it can be reduced — and when it absolutely cannot
For an Initial Acquisition (buying a business you've never owned any part of, from someone unrelated), the 10% floor is generally treated as a hard requirement.
For Business Expansion and Owner Buyout transactions, lenders may have limited discretion based on liquidity, working capital, and balance sheet strength. If you're unsure which bucket your deal fits, start with the SBA application guide and talk to a lender early.
What this actually costs on a real deal
Example: You're buying a business for a total project cost of $1,500,000 (purchase price plus closing costs, working capital, and any real estate).
- Required equity injection: $150,000 (10%)
- If the seller agrees to carry $75,000 on full standby, that satisfies half your requirement
- You'd still need $75,000 in cash, a personal loan, or another qualifying source to close the gap
Common mistake
Buyers frequently assume seller financing alone can cover their entire down payment requirement. It can't—standby seller debt is typically capped at half of the required injection when it is counted toward equity. Structuring a deal assuming 100% seller-carry equity is one of the fastest ways to have a loan application rejected or delayed mid-underwriting.
FAQ
Can I use a HELOC or personal loan for my SBA equity injection?
Yes, if repayment of that loan is documented as coming from a source other than the acquired business's cash flow — a salary paid to you by the business you're buying typically doesn't qualify as an independent repayment source.
Does the seller have to wait to get paid if they carry a note?
Yes. If seller debt is counted as part of your equity injection, it must be on full standby (no principal or interest payments) for the full SBA loan term (often up to 10 years for acquisition financing).
Is the 10% based on the purchase price or something else?
It’s based on total project cost, which can include purchase price plus closing costs, professional fees, and working capital included in the loan request — not just the headline sale price.
Can seller financing cover my entire down payment?
No. Standby seller debt is generally limited to no more than half of the required injection when it’s being counted toward equity. Plan for the remainder to come from cash or another eligible source.
