Debt service coverage ratio (DSCR) for buying a business
Short answer
The debt service coverage ratio (DSCR) is the business's cash flow available to pay debt divided by the total yearly payments on that debt. SBA lenders require at least 1.25 for an Initial Acquisition (1.15 for a Business Expansion) under SOP 50 10 8.1, using the last fiscal year or the average of the last two.
The SBA's historical DSC uses EBITDA over post-closing debt service; lenders may add justified adjustments, but can't rely on projections to meet the minimum.
DSCR is the number that decides how big your loan can be. It's also a useful personal test: if the business can't cover its debt with room to spare after paying you a living wage, you're buying a job with a lot of risk attached.
The formula
DSCR = cash flow available for debt service ÷ total annual debt service
- Cash flow: for the SBA's historical test, EBITDA. In practice for an owner-operated business, that's SDE minus a reasonable salary for you (or a manager), with justified adjustments.
- Debt service: all principal and interest on post-closing debt: the SBA loan, any paying seller note, assumed loans, equipment financing.
SBA minimums (SOP 50 10 8.1)
| Transaction type | Minimum DSC |
|---|---|
| Initial Acquisition | 1.25 |
| Business Expansion | 1.15 |
| Owner Buyout | 1.25 |
| ESOP and Cooperative | 1.25 |
Measured on the last fiscal year-end or the average of the last two, on a historical or adjusted basis. The lender also has to show global cash flow (you, the business, any affiliates) at 1:1, and must evaluate your projections but can't use them to meet the requirement. For deals needing a QoE ($3 million and up), the QoE's earnings must be used.
A worked example
Illustrative example, not a real deal
Price $800,000 plus $50,000 of working capital and costs = $850,000 project. Equity 10% = $85,000. SBA loan $765,000 at an example 10.5% over 10 years = about $123,900 a year.
Verified SDE is $260,000. You need an $80,000 salary, and the business needs about $12,000 a year of equipment replacement. Cash for debt = $260,000 − $80,000 − $12,000 = $168,000. DSCR = $168,000 ÷ $123,900 ≈ 1.36.
Now suppose $40,000 of the seller's add-backs don't hold up. Verified SDE is $220,000, cash for debt is $128,000, and DSCR falls to about 1.03. The same price no longer works.
Historical vs adjusted DSC
Historical DSC uses EBITDA as reported. Adjusted DSC lets the lender include prudent, justified changes to cash flow: savings realized through the transaction, seller discretionary expenses, owner compensation, distributions and S-corp tax distributions, non-recurring income (subtracted), unfunded capex. Each adjustment has to be explained in the credit memo, and adjustments without support are ineligible. If you want an add-back to count, bring the evidence.
Check your own deal
Use the SBA DSCR calculator with SDE built from solid add-backs (try the SDE calculator first). If coverage is under 1.25, the fixes are a lower price, more equity, a longer seller note or standby structure, or walking away. For the full SBA rule set see SBA 7(a) for acquisitions.
Working backwards from coverage to price
Illustrative example, not a valuation or a lending decision
Verified SDE is $300,000. You need $95,000 to live on and $15,000 a year for equipment, leaving $190,000 for debt. At 1.25 coverage, debt service can be up to $190,000 ÷ 1.25 = $152,000 a year. At an example 10.5% over 10 years, each $100,000 borrowed costs about $16,200 a year, so the loan can be about $938,000. With a 10% equity injection on total project cost, that supports a project of roughly $1,040,000, and after $60,000 of closing costs and working capital, a price of about $980,000, before any seller note. If the asking price is $1.2 million, the earnings don't support it with this structure, whatever multiple anyone quotes. That's the calculation the DSCR calculator runs.
What counts in debt service, and what doesn't
| Item | In debt service? | Note |
|---|---|---|
| SBA loan principal and interest | Yes | At the actual or expected rate; variable rates change it |
| Seller note with payments | Yes | Interest-only non-standby debt is underwritten on an amortization of no more than 10 years |
| Seller note on full standby | No payments during the SBA loan | SBA Form 155; may accrue interest |
| Equipment loans and capital leases | Yes | Including ones you assume |
| Working capital line | Usually, as the lender calculates it | Ask how your lender treats it |
| Rent | No, it's an operating expense | Already deducted before EBITDA |
Global cash flow: your budget is tested too
For SBA loans, lenders also look at global cash flow: the business's cash flow together with your personal income and obligations. If an owner compensation adjustment is part of the analysis, the SOP requires the global analysis at 1:1 coverage. In plain terms: after the business pays the debt, does the salary you'll take, plus any other household income, cover your mortgage, car loans and living costs? If your plan only works with a salary the business can't afford after debt, the deal doesn't really work, even if business coverage looks fine.
Worked example: stress-testing coverage
Illustrative example continued, not current rates
From the deal above: cash for debt of $168,000 and debt service of $123,900 gives DSCR of about 1.36. Now three stresses. A 10% fall in SDE ($26,000) drops cash for debt to $142,000: DSCR 1.15. A 2-point rise in the loan rate (to 12.5%) adds about $10,500 a year of payments: DSCR about 1.25 on the original earnings, right on the line. Both together: $142,000 ÷ $134,400 = 1.06. The deal passes the lender's test today and fails it under fairly ordinary bad news. That doesn't make it a bad deal, but it tells you how much margin you have, and that a cash reserve outside the business isn't optional.
SBA's September 2026 technical update confirmed there's no reduced coverage standard for 7(a) Small or SBA Express acquisition loans; the same Appendix 15 minimums apply whatever the loan size. Run your own stress tests in the DSCR calculator.
Worked example: a seller note that isn't on standby
Illustrative example, not a real deal or rates
Earnings available for debt service are $250,000. The buyer borrows $900,000 from an SBA lender over 10 years at 10.5% (an example rate): about $145,700 a year in payments, so coverage is $250,000 ÷ $145,700 = 1.72. The seller also carries a $100,000 note over 5 years at 6%, with payments starting at closing: about $23,200 a year. Total debt service becomes $168,900, and coverage falls to $250,000 ÷ $168,900 = 1.48. Still above the 1.25 minimum, but with less room for a bad year. If the note were on full standby, its payments wouldn't count in the first years, though the lender will still ask how it will be paid later.
Coverage in a seasonal business
Lenders test annual coverage, but loan payments are monthly. A business that earns most of its profit in a few months can pass the annual test and still struggle to make payments in the slow season. Build a monthly cash flow with the loan payment in every month, and check that the low months are covered by cash in reserve or working capital in the loan. Ask the lender whether payment timing can be adjusted for seasonality.
Frequently asked questions
What DSCR do SBA lenders require to buy a business?
At least 1.25 for Initial Acquisitions, Owner Buyouts and ESOP/co-op deals, and 1.15 for Business Expansions, under SOP 50 10 8.1. Many lenders set higher internal targets.
What earnings go in the numerator?
For the SBA's historical DSC, EBITDA. Lenders can make prudent adjustments (owner compensation, seller discretionary expenses, non-recurring income, unfunded capex) if each is justified. Owner compensation changes need a global cash flow analysis.
Does the seller note count in DSCR?
A paying seller note does. A note on full standby doesn't, because it has no payments during the SBA loan.
What is global DSCR?
Coverage that includes the buyer's personal income and debts and any affiliated businesses. The SOP requires a global cash flow analysis at 1:1.
Can projections help me meet the SBA's DSCR requirement?
No. Under SOP 50 10 8.1, lenders may review projections but can't rely on them to meet the debt service coverage requirement for a change of ownership. Coverage has to work on historical earnings (last fiscal year or the average of the last two), with justified adjustments.
What DSCR do lenders want for a Business Expansion?
Under SBA SOP 50 10 8.1, the minimum is 1.15 for a Business Expansion, compared with 1.25 for Initial Acquisitions, Owner Buyouts and ESOP or cooperative transactions. Lenders may set higher requirements of their own.
