The Modern Acquirer

The SBA Capital Stack Worksheet, Built for SOP 50 10 8.1

A lender decides whether a deal qualifies and may add requirements; this worksheet estimates the stack and does not model every fee waiver. Enter an Initial Acquisition to see project cost, the minimum equity injection, how much of it a standby seller note can fill, the loan with its financed fee, and debt service coverage against the applicable floor.

What's inside

  • A stack calculator. Price, valuation, EBITDA, working capital, closing costs, rate, seller note and outside equity in. Project cost, injection, loan, debt service, coverage and the price ceiling out.
  • A checklist. What I'd do before calling a lender, grouped into the numbers, the money and the documents.
  • A print view. The print button keeps your deal's numbers and your ticks, or saves them as a PDF. Nothing you enter leaves your browser.

A preview

For example, enter an illustrative purchase price, historical earnings, working capital and closing costs. The worksheet adds the financed guaranty fee to project cost [E893, E895]. Counting the fee in project cost is a model assumption; your lender may not. It then calculates the minimum injection for an Initial Acquisition from that total [E841]. At least half the minimum must come from unlimited sources such as unborrowed cash [E842]. It estimates coverage from historical earnings and only the modeled SBA loan payment [E844]. Add any other post-transaction debt service before deciding whether coverage clears the floor [E844]. Your lender must confirm the inputs, sources and result.

The worksheet

SOP 50 10 8.1 applies to loans given an SBA loan number from October 1, 2026; applications submitted through September 30, 2026 remain under SOP 50 10 8.0[1]. The worksheet encodes the rules that change the stack. For an Initial Acquisition, the minimum injection is 10% of total project cost, not of price; lenders may reduce or waive that minimum for Business Expansions and Owner Buyouts[2]. A seller note on full standby, other standby debt and non-controlling minority investors under 20% with no control rights together fill at most half of the required injection[3]. Total acquisition debt, including seller debt not on full standby, stops at the business valuation[4]. Above a $350,000 purchase price, or when buyer and seller are closely related, that valuation must come from an independent qualified source the lender engages[4]. The worksheet finances the guaranty fee into the loan, which the SOP allows[5][6], and stops the loan at the $5M Standard 7(a) maximum[6]. For Initial Acquisitions, Owner Buyouts and ESOPs, coverage has a 1.25x floor; Business Expansions have a 1.15x floor[7]. Coverage uses the last fiscal year or a two-year average[7]. Lenders must review projections but cannot use them to meet the minimum, except for owner-occupied Special Purpose Property deals[7]. The default rate of 8.75% is the FY2026 through June 2026 median for change-of-ownership loans[8]. The displayed minimum injection (10%)[2], limited-source cap (50%)[3], coverage floor (1.25x)[7] and quality-of-earnings threshold ($3M)[9] follow those rules. Coverage here counts only the modeled SBA loan payment; add other post-transaction debt service before treating a displayed result as clearing the 1.25x floor[7].

Prepared for the lender, not for you or the seller. Debt stops at it. Set it equal to price if there is no gap.

Capped at 50% together with any sub-20% investors.

  • SBA 7(a) loan$2,038,346
  • Your cash (unlimited sources)$113,241
  • Seller note, full standby$113,241
  • Price is 4.44x EBITDA. At this rate an SBA-only stack carries about 5.91x at 1.25x DSC, 90% financed, before working capital and fees.
  • Under $3,000,000, a quality of earnings report is not required by the SOP. Many lenders ask for one anyway.

Method: the FY2027 upfront fee tiers use an 85% guaranty for loans of $150,000 or less, charged at 2% of the guaranteed portion; larger loans use a 75% guaranty, charged at 3% through $700K, then 3.5% of the guaranteed portion up to $1M and 3.75% above[15][5]. The 0% FY2027 waiver for some manufacturer, food-supply-chain and rural loans of $700K or less is not modelled[5]; monthly amortization over ten years as an illustrative model assumption (the observed median term was 120 months[8]); and a loop to settle the fee, because the fee is financed. It reproduces the three worked scenarios in the SBA stack analysis on this site. Illustrative arithmetic, not a lending decision: lenders add their own requirements, and fee notices change each fiscal year. Not lending, legal or investment advice.

Questions

Does this tell me whether I qualify?

No. It does the arithmetic the SOP sets out. A lender decides, and adds its own requirements on top.

Why can't a seller note fill the whole injection?

The SOP treats a full-standby seller note, other standby debt and non-controlling minority investors under 20% with no control rights as limited sources, capped together at half the minimum [E842]. The other half has to come from unlimited sources: mostly the buyer's unborrowed cash, a gift, or a personal loan repaid from outside the business [E842].

What if the price is above the valuation?

Total acquisition debt, including seller debt not on full standby, stops at the business valuation [E847]. Above a $350,000 purchase price, or when buyer and seller are closely related, that valuation must come from an independent qualified source the lender engages [E847]. Equity or additional debt on full standby, such as a seller note, may cover the price gap [E847]. The worksheet shows that gap as extra equity; it does not model a full-standby note in that layer. Confirm the source with your lender.

Is anything I enter saved?

No. The worksheet runs in your browser. Nothing you type or tick is stored or sent.
