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

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

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.
