What Is DSCR and Why Do Lenders Care?
The Debt Service Coverage Ratio (DSCR) is one of the most critical metrics in commercial lending. It measures a business's ability to generate enough cash flow to cover its debt obligations. For SBA lenders, DSCR is a primary underwriting criterion because it directly answers the fundamental question: can this business pay back the loan?
A DSCR of 1.0 means the business generates exactly enough income to cover its debt payments with nothing left over. Anything below 1.0 means the business is losing money relative to its obligations. SBA lenders typically require a minimum DSCR between 1.15x and 1.25x, depending on the lender, the deal structure, and the overall risk profile of the transaction. Strong deals with experienced borrowers may get approved at 1.15x, while riskier transactions or newer businesses will need 1.25x or higher.
How to Calculate DSCR
The formula is straightforward:
DSCR = Net Operating Income / Annual Debt Service
Net Operating Income (NOI) is your business's total revenue minus all operating expenses, but before debt payments, income taxes, depreciation, and amortization. Think of it as the cash the business generates from operations that is available to service debt.
Annual Debt Service includes all principal and interest payments due on business debt over a 12-month period. For SBA underwriting, this includes the proposed new SBA loan payment plus any existing business debt that will remain after closing. Some lenders also include personal obligations of the guarantor when calculating global DSCR.
For example, if a business generates $500,000 in NOI and has $400,000 in total annual debt payments, the DSCR would be $500,000 / $400,000 = 1.25x. This meets the standard SBA minimum and indicates the business generates 25% more income than it needs to cover debt.
Common Add-Backs SBA Lenders Accept
Add-backs are adjustments made to the business's reported income to reflect its true cash-generating ability. Lenders recognize that many small businesses run personal expenses through the company or have one-time costs that distort profitability. Common add-backs that SBA lenders accept include:
- Owner's salary and compensation: The current owner's W-2 wages, distributions, or draws that the new buyer will receive as income.
- One-time expenses: Legal fees from a prior lawsuit, moving costs, or other non-recurring charges that won't continue under new ownership.
- Depreciation and amortization: Non-cash expenses that reduce reported income but do not affect actual cash flow.
- Excessive owner perks: Personal vehicle leases, travel, meals, or other discretionary expenses run through the business.
- Interest expense on debt being refinanced: If the SBA loan will pay off existing high-interest debt, that interest expense can be added back.
These add-backs can dramatically change the picture. A business showing $200,000 in net income might have $150,000 in add-backs, giving it $350,000 in adjusted cash flow. This is why understanding add-backs is essential for both borrowers and originators when packaging SBA deals.

How to Improve Your DSCR
If your DSCR is falling short of lender requirements, there are several strategies to improve it before submitting your application:
- Increase NOI: Look for ways to boost revenue or reduce operating expenses before the loan application period. Even small improvements in margins can meaningfully shift DSCR.
- Reduce debt payments: Pay off small balances, consolidate high-interest debt, or negotiate lower payments on existing obligations to reduce your annual debt service.
- Extend the loan term: A longer amortization period reduces the monthly payment, which lowers annual debt service and increases DSCR. SBA 7(a) loans can go up to 25 years for real estate.
- Increase the down payment: Putting more equity into the deal reduces the loan amount and therefore the annual debt service required.
- Document all legitimate add-backs: Work with your CPA to identify every allowable adjustment. Many borrowers leave add-backs on the table because they don't know what qualifies.
Global DSCR vs. Project DSCR
SBA lenders evaluate cash flow coverage at two levels, and understanding the difference is critical for deal preparation. Project DSCR looks only at the income and debt associated with the specific business or project being financed. It answers the question: can this business alone cover the proposed loan payment?
Global DSCR takes a broader view. It includes all income sources available to the borrower and guarantors (such as W-2 income from a spouse, rental income, other business income) and all personal and business debt obligations. Most SBA lenders calculate both ratios. A deal with a weak project DSCR of 1.10x might still get approved if the global DSCR is 1.40x because the borrower has significant outside income to backstop the loan.
When packaging your loan request, always present both calculations. Showing the lender that you understand the distinction demonstrates financial sophistication and builds confidence in your ability to manage the debt.
