Short answer: DSCR (debt service coverage ratio) is the property's or business's cash flow divided by its yearly loan payments. A 1.00 ratio means the cash flow covers the payments exactly, with no cushion. Every lender sets its own minimum, and it changes with the loan type and property type. For example, SBA's current lending rules (SOP 50 10 8.1, effective October 1, 2026) require at least 1.15 for standard 7(a) and 504 loans, plus at least 1.0 on a global basis. Income-property lenders usually want a cushion above 1.0, and riskier property types usually need more.
How DSCR is calculated
The basic formula is simple:
DSCR = net operating income (NOI) ÷ annual debt service
- Net operating income is the property's income (rents and other income, after vacancy) minus operating expenses such as property taxes, insurance, utilities, repairs, management and reserves. It does not subtract loan payments, depreciation or income taxes.
- Annual debt service is the total principal and interest due on the loan over a year. Lenders usually include every loan secured by the property, not just the new one.
A simple, made-up example: a building with $150,000 of NOI and $120,000 of yearly debt service has a DSCR of 1.25. The cash flow covers the payments with a 25% cushion. If NOI fell to $120,000, the ratio would be 1.00, meaning no cushion at all.
For an owner-occupied business property (for example, an SBA loan), the lender usually looks at the business's operating cash flow instead of rent. SBA's rules define it as earnings before interest, taxes, depreciation and amortization (EBITDA), with certain adjustments.
What minimums lenders use
There is no single number. Each lender sets its own credit policy, and federal bank examiners expect banks to set minimum coverage standards for each type of loan they make (see the OCC Comptroller's Handbook on commercial real estate lending). A few published benchmarks help show the range:
- SBA 7(a) and 504 loans. Under SBA SOP 50 10 8.1 (effective October 1, 2026), a standard 7(a) or 504 applicant needs a DSCR of at least 1.15 on a historical and/or projected basis, and at least 1.0 on a global basis (counting owners' and affiliates' cash flow and debts). 7(a) Small Loans for purposes other than buying a business need at least 1.10. Business acquisitions follow separate rules.
- Federal "qualifying CRE loan" standards. Federal risk-retention rules (12 CFR 43.17) define a very conservative loan with a DSCR of at least 1.25 for multifamily, 1.5 for qualifying leased commercial property and 1.7 for other commercial property. These are standards for a securitization exemption, not everyday minimums, but they show that lenders view multifamily as lower risk than many other property types.
- Income-property loans in general. Bank, credit union, life company and private lenders set their own ratios. A stabilized apartment building with steady leases usually needs less cushion than a hotel, a single-tenant retail building or a property with a lot of near-term lease rollover.
What lenders look at besides the ratio
- Which numbers they use. Many lenders use the last full year or two of actual results, a current rent roll and in-place leases. Some will consider projected income, often with conditions.
- Their own expense assumptions. Lenders often add a vacancy factor, a management fee or replacement reserves even if you self-manage, so their NOI can be lower than yours.
- How the payment is figured. The ratio depends on the loan amount, the amortization and the rate the lender uses to test the loan, so the same property can show different ratios with different lenders.
- Loan-to-value, credit and liquidity. DSCR is one test. Lenders also review value, your credit, your reserves and your experience with this kind of property.
- Tenant and lease quality. Who the tenants are, how long their leases run and when they expire.
If your DSCR is tight
- Request a smaller loan. Lower debt service raises the ratio. More down payment or equity may be the cleanest fix.
- Ask about a longer amortization or an interest-only period, where a program allows it.
- Document income the lender may not see yet, such as signed new leases, rent increases already in effect or other income (parking, laundry, storage).
- Clean up the expense history. Separate one-time repairs from recurring costs so the lender can see the real operating picture.
- Consider a bridge loan first. For a property still being leased up or renovated, a short-term loan may come first, with permanent financing once the income is stable.
I look at the numbers the way a lender will before your file goes anywhere. That helps us find the right fit and avoid surprises. Have a tight ratio or a file another lender turned down? Send me the scenario. Related: DSCR investor loans (1-4 units), multifamily loans, bridge loans and SBA loans.
Questions about this topic
What is a good DSCR for a commercial loan?
It depends on the lender, the loan type and the property. A ratio of 1.00 means cash flow exactly covers the payments, so lenders want a cushion above that. SBA's current rules require at least 1.15 for standard 7(a) and 504 loans, and many income-property lenders want more for riskier property types.
How do lenders calculate DSCR?
They divide net operating income (income after vacancy, minus operating expenses) by the total yearly principal and interest payments on the loans secured by the property. For SBA loans, they usually use the business's operating cash flow instead.
Can I get a commercial loan with a DSCR below 1.0?
It is difficult with a standard permanent loan, because the property doesn't cover its own payments. Options may include a smaller loan, more equity, or a short-term bridge loan while income improves, subject to lender approval.
Does DSCR use my personal income?
Mostly no for income-property loans, which focus on the property's cash flow. Many lenders still review your credit, reserves and experience, and SBA loans also look at global cash flow, including owners' income and debts.
Is a DSCR loan for 1-4 unit rentals the same thing?
It uses the same idea, rent compared with the payment, but 1-4 unit DSCR programs are usually calculated on gross rent versus the full monthly housing payment and follow their own program guidelines.
