DSCR Formula and Calculation
Basic DSCR Formula:
DSCR = Net Operating Income ÷ Total Annual Debt ServiceComprehensive Formula:
DSCR = (Gross Rental Income - Operating Expenses) ÷ (Annual Principal + Interest + PMI + Other Debt Service)What DSCR Measures:
The property's ability to generate sufficient income to cover all debt payments, expressed as a ratio where 1.0 means the property exactly breaks even on debt service, and anything above 1.0 indicates a safety cushion.
DSCR Interpretation:
DSCR < 1.0
Negative Cash Flow: Property cannot cover debt payments from income alone
DSCR = 1.0
Break-Even: Property exactly covers debt payments with no cushion
DSCR > 1.0
Positive Cash Flow: Property generates excess income after debt service
