DSCR = Net Operating Income (NOI) / Total Annual Debt Service (Principal + Interest)Key Takeaway
Strong coverage of 1.48x provides a 15.5% cash buffer before hitting the lender's 1.25x covenant limit.
Strategic Advantages
Institutional credit underwriting standard Clear safety margin calculation
Risk & Limitations
Assumes steady occupancy and operating expenses
Pro Financial Strategy
Commercial lenders typically require a 1.20x to 1.30x DSCR plus a minimum 65-75% Loan-to-Value (LTV) ceiling.

About the DSCR & Commercial Loan Sizing
What This Calculator Does
DSCR is the primary underwriting metric commercial banks and private credit funds use to size loans and enforce covenants.
Why This Calculator Matters
A DSCR below 1.0x means operating income cannot cover loan payments, creating severe default risk.
How the Calculation Works
Input gross revenue, operating expense ratio, loan interest rate, amortization years, and required bank minimum DSCR hurdle (e.g. 1.25x).
When to Use This Calculator
- -- Applying for commercial mortgages / multifamily loans
- -- Underwriting acquisition debt sizing
- -- Quarterly banking covenant reporting
Benefits
- -- Calculates maximum allowable loan amount
- -- Stress-tests income declines before covenant breach
- -- Visual safety margin meter
Mathematical Formula
DSCR = Net Operating Income (NOI) / Total Annual Debt Service (Principal + Interest)Measures the cushion between a property or company's operating cash flow and its mandatory annual loan debt obligations.
Variables Explained
| Variable | Symbol | Description |
|---|---|---|
| Annual Gross Revenue | Rev | Total property rental or corporate revenue ($) |
| Operating Expense Ratio % | OpEx% | Expenses as % of revenue (typically 35-45%) |
| Proposed Loan Amount | Loan | Requested commercial debt ($) |
| Interest Rate % | Rate | Commercial loan APR % |
| Amortization Term (Years) | Term | Standard 25 or 30 year amortization |
| Lender Minimum DSCR Hurdle | Hurdle | Bank minimum requirement (typically 1.20x to 1.35x) |
Calculation Workflow
Enter calculation parameters: Annual Gross Revenue, Operating Expense Ratio %, Proposed Loan Amount, Interest Rate %
Apply mathematical derivation: DSCR = Net Operating Income (NOI) / Total Annual Debt Service (Principal + Interest)
Validate input boundary constraints and check against statutory tolerances
Compute principal and secondary outputs with standard rounding conventions
Generate dynamic visual projections and breakdown analysis
Step-by-Step Example
$1.2M Gross Revenue with 40% OpEx ($720K NOI) on a $6.0M loan at 6.5% over 25 years.
- Annual Debt Service: $486,000
- Calculated DSCR: 1.48x
- Status: Approved (Exceeds 1.25x Hurdle)
Interpreting Your Results
Strong coverage of 1.48x provides a 15.5% cash buffer before hitting the lender's 1.25x covenant limit.
Advantages
- -- Institutional credit underwriting standard
- -- Clear safety margin calculation
Limitations
- -- Assumes steady occupancy and operating expenses
Common Mistakes
- -- Failing to reserve for capital expenditures (CapEx replacement reserves) in NOI.
Helpful Tips
- -- Commercial lenders typically require a 1.20x to 1.30x DSCR plus a minimum 65-75% Loan-to-Value (LTV) ceiling.
