Introduction to Debt Service Coverage Ratio Calculator (DSCR)

The debt service coverage ratio (DSCR) measures a property’s or business’s ability to cover its debt payments with its net operating income. It is calculated by dividing net operating income by total debt service (principal and interest). Lenders use DSCR to assess loan risk, typically requiring a ratio of 1.25 or higher for commercial mortgages and investment properties. A DSCR above 1.0 means income covers debt payments. Below 1.0 means income is insufficient. This DSCR Calculator helps you determine your debt service coverage ratio instantly. Enter your net operating income and annual debt service. The calculator shows your DSCR, loan eligibility, and cash flow after debt payments. Toolraxy built this calculator to help real estate investors, business owners, and lenders evaluate debt capacity and loan qualification.

Formula Section

Debt service coverage ratio:

DSCR = Net Operating Income ÷ Annual Debt Service

Annual debt service:

Annual Debt Service = Monthly Mortgage Payment × 12

Monthly debt service:

Monthly Debt Service = Annual Debt Service ÷ 12

Net operating income (NOI):

NOI = Effective Gross Income – Operating Expenses

Cash flow after debt service:

Cash Flow = NOI – Annual Debt Service

Maximum loan amount based on target DSCR:

Max Debt Service = NOI ÷ Target DSCR
Max Loan Amount = Max Debt Service × Loan Factor

DSCR interpretation scale:

  • DSCR ≥ 1.50: Strong (excellent loan eligibility)

  • DSCR 1.25 – 1.49: Acceptable (standard loan requirement)

  • DSCR 1.00 – 1.24: Marginal (may require compensating factors)

  • DSCR < 1.00: Weak (negative cash flow, loan likely denied)

Where:

  • NOI = Net Operating Income (income after operating expenses)

  • Debt Service = Total annual loan payments (principal + interest)

  • DSCR = Debt Service Coverage Ratio

  • Target DSCR = Minimum DSCR required by lender (typically 1.25)

Real-Life Examples Section

  • Example scenario:

    • Net operating income (NOI): $150,000

    • Annual debt service: $100,000

    • Monthly debt service: $8,333

    • Target DSCR: 1.25

    Calculations:

    • DSCR: $150,000 ÷ $100,000 = 1.50

    • Cash flow after debt service: $150,000 – $100,000 = $50,000

    • DSCR assessment: Strong (≥1.50)

    • Loan eligibility: Excellent
