How to Calculate DSCR: Formula + SBA 1.15 Threshold 2026
DSCR = Net Operating Income ÷ Total Annual Debt Service — a ratio above 1x means the business generates more cash than it owes in annual debt payments. SBA 7(a) requires a minimum global DSCR of at least 115% coverage (business + personal debt); most bank lenders require 125% or higher.
The DSCR formula
DSCR = Net Operating Income (NOI) / Total Annual Debt Service. Net Operating Income is your business's earnings before interest expense and income taxes (EBIT), sometimes calculated as gross revenue minus operating expenses (excluding debt payments). Total Annual Debt Service is the sum of all principal and interest payments due in a 12-month period.
Worked example — DSCR calculation
A landscaping business has annual revenue of $600,000, operating expenses (payroll, fuel, equipment maintenance, insurance) of $420,000, giving NOI of $180,000. Annual debt service on an existing equipment loan is $60,000. A proposed new SBA loan adds $48,000/year in payments. Total annual debt service = $108,000. DSCR = $180,000 ÷ $108,000 = 1.67x. Well above the 1.15x SBA minimum.
SBA and bank thresholds
- SBA 7(a) — typically requires 1.15x DSCR or higher on a global basis (including all owner debt).
- Conventional bank loans — most community banks and regional banks prefer 1.25x minimum, with stronger credits at 1.35x+.
- SBA 504 (real estate/equipment) — uses same 1.15x baseline but applies global analysis including owner personal obligations.
- Business lines of credit — lenders look at trailing 12-month average deposits vs. existing fixed obligations rather than a formal DSCR calculation in many cases.
Global DSCR vs. business-only DSCR
SBA underwriters calculate a global DSCR that includes the owner's personal debt obligations (mortgage, auto loans, student loans) alongside business debt. If the business shows 1.40x but the owner has a $4,000/month mortgage and $1,500/month in personal debt that isn't covered by personal income, the global DSCR may still fail the 1.15x test. Always calculate global DSCR before applying.
How to improve your DSCR
- Increase NOI — reduce controllable operating expenses or grow revenue before applying.
- Reduce existing debt — pay off or consolidate high-payment obligations before adding new debt.
- Refinance higher-rate debt — lowering interest rate or extending amortization reduces annual debt service.
- Time the application — apply after a strong 12-month revenue period, not mid-slowdown.
- Separate owner draws — excessive owner salary that depresses NOI can sometimes be restructured before underwriting.
DSCR vs. DTI vs. other underwriting ratios
DTI (Debt-to-Income ratio) is used primarily for personal loans and mortgages — it divides total monthly debt payments by gross monthly income. DSCR is the business equivalent but inverts the math: higher is better. Other ratios lenders use include the current ratio (current assets ÷ current liabilities, ideally 1.5x+), quick ratio (liquid assets ÷ current liabilities), and debt-to-equity ratio.

Key takeaways
- DSCR = Net Operating Income ÷ Total Annual Debt Service; 1.25x means you earn $1.25 for every $1.00 of debt payments.
- SBA 7(a) minimum is 1.15x global DSCR; most bank lenders prefer 1.25x+.
- Global DSCR includes owner personal debt — a strong business DSCR can still fail if personal obligations are high.
- Improve DSCR by increasing NOI, paying down existing debt, or refinancing to lower annual payments.
- DSCR is the most important single metric in SBA and bank underwriting — insufficient cash flow is the top cause of denial.
