DSCR for small business loans: what it is and how to calculate it
Updated 2026-11-10
Short answer: Debt service coverage ratio (DSCR) equals your annual operating cash flow divided by your annual loan payments (principal plus interest). A DSCR of 1.25 means the business earns $1.25 for every $1.00 of payments due. SBA requires at least 1.10 on 7(a) Small loans up to $350,000 and 1.15 on larger 7(a) loans, and lenders commonly want about 1.25.
The formula
DSCR = operating cash flow / debt service
SBA defines both terms in its lender rulebook, SOP 50 10 8.1 (SBA):
- Operating cash flow (OCF) is earnings before interest, taxes, depreciation and amortization (EBITDA). Lenders may then add or subtract items such as unfunded capital expenditures, non-recurring income, owner's draws and distributions.
- Debt service (DS) is the future required principal and interest payments on all business debt, including the new loan you are asking for.
Two details trip people up. First, debt service means principal and interest, not interest alone. Second, it covers every business debt: the equipment loan, the credit card used for inventory, the vehicle note, and the new loan. Lenders check this against your bank statements. SBA tells lenders on small loans to review the two most recent months of activity on the primary operating account to confirm that all commercial debts were counted (SBA Procedural Notice 5000-876777).
Worked example
A small business owner wants a $150,000 loan at 10.5% over 10 years. The rate and term are illustrative, not a quote. The business has one existing equipment loan.
Step 1: operating cash flow (EBITDA)
| Line | Amount |
|---|---|
| Net income | $24,000 |
| Plus interest expense | $6,000 |
| Plus taxes | $0 (LLC taxed to the owner) |
| Plus depreciation | $12,000 |
| EBITDA | $42,000 |
Step 2: debt service
| Debt | Annual payment |
|---|---|
| Existing equipment loan (principal and interest) | $9,000 |
| New $150,000 loan, 10.5%, 10 years ($2,024 a month) | $24,288 |
| Total debt service | $33,288 |
Step 3: divide
$42,000 / $33,288 = 1.26
The business clears 1.25 by a small margin. The monthly payment comes from the standard loan payment formula, and you can test other amounts and rates in the loan payment calculator or run the whole ratio in the DSCR calculator.
Note that this uses last year's figures. If you are a start-up there is no history, so the lender uses your projections instead, and the projected operating cash flow has to carry the full debt service. That is why the projections need defensible assumptions, and why a financial projection template that calculates the ratio for you saves rework. See our guide to what an SBA lender wants in financial projections.
What a DSCR of 1.25 means
A ratio of 1.00 means cash flow exactly covers the payments, with nothing left over. Below 1.00, the business cannot pay its debts from operations. At 1.25, cash flow could fall about 20% before payments are no longer covered (1 / 1.25 = 0.80). That cushion is what lenders are buying. A restaurant with a slow January or a cleaning company that loses its biggest account needs it.
Minimums lenders use
| Test | Minimum DSCR | Source |
|---|---|---|
| 7(a) Small loan, up to $350,000 | 1.10, historical or projected | SBA SOP 50 10 8.1, Section B, Ch. 2 |
| Standard 7(a), above $350,000 | 1.15, plus 1.0 global | SBA SOP 50 10 8.1, Section B, Ch. 1 |
| 504 loan | 1.15 on historical figures | SBA SOP 50 10 8.1 |
| 7(a) initial acquisition (buying a business) | 1.25 | SBA SOP 50 10 8.1, Appendix 15 |
| SBA lender comfort target | About 1.25 | Reported by GoSBALoans |
The 1.10 test for small loans started March 1, 2026, replacing the old credit-score screen. For 7(a) Small loans the ratio can be shown on last year's statements, on last year plus an interim statement, or on 12-month projections that reach 1.10 within one year of funding. Conventional bank loans have no single rule. Each bank sets its own, so ask yours for its minimum.
Global DSCR
On standard 7(a) loans, SBA also requires a global DSCR of at least 1.0. Global means the lender combines the business with the owner's personal income and obligations, and with any affiliated business, so that the owner's mortgage, car payments and other debts are in the denominator. If your personal debts are heavy, a business that passes on its own can still fail globally.
How to improve a low DSCR
There are only two levers: raise the top number or lower the bottom one.
Raise operating cash flow
- Cut costs you can document as permanent, such as a cheaper insurance quote or a renegotiated supplier contract.
- Raise prices on the jobs or menu items with the weakest margin.
- Back projected growth with something checkable, such as signed customer agreements or a lease in a high-traffic spot. Lender guides recommend this for projections (GoSBALoans).
Lower debt service
- Pay off a small existing loan before applying. In the example, removing the $9,000 equipment payment lifts the ratio from 1.26 to 1.73.
- Borrow less. Cutting the new loan to $125,000 drops its payments to about $20,240 and the ratio to 1.44.
- Choose the longest term that fits what you are buying, since payments fall as the term grows.
- Increase your equity injection so that you need less debt.
You can also work backward. At 1.25, the example business can support total payments of $33,600 a year ($42,000 / 1.25). After the $9,000 existing loan, that leaves $24,600 for the new loan, which supports a loan of about $152,000 on the same terms. Run the same math with your own EBITDA before you ask for a number.
Common mistakes
- Using net profit instead of EBITDA, or leaving out a fair owner salary so cash flow looks higher than it is.
- Leaving a small debt out of the calculation. The lender will find it in the bank statements.
- Testing only the best case. Run the ratio with revenue 10% lower and see whether it holds.
- Forgetting that the new loan payment starts before the business reaches full volume.
Ask your lender or accountant how they adjust cash flow, because definitions differ at the margins.
Next step
Enter your own EBITDA and loan terms in the DSCR calculator and see where you land against 1.10, 1.15 and 1.25. If the ratio is thin, adjust the loan amount or your cost assumptions before you apply.
