The Business Debt Coverage Ratio Calculator helps business owners and financial professionals evaluate debt repayment capacity using the Debt Service Coverage Ratio. Enter your revenue, expenses, and debt payments to see whether your business meets lender benchmarks, how much additional debt you could take on, and where your breakeven revenue sits -- all essential for loan applications and financial planning in 2026.
How DSCR Is Calculated
The calculator applies standard financial formulas used by commercial lenders to assess debt capacity:
Net Operating Income (NOI) = Annual Revenue - Operating Expenses
Cash-Basis NOI = NOI + Depreciation & Amortization
DSCR = NOI / Annual Debt Payments
Cash-Basis DSCR = Cash-Basis NOI / Annual Debt Payments
Max Debt Service at 1.25x = NOI / 1.25
Breakeven Revenue = Operating Expenses + Annual Debt Payments
| Metric | Formula | Example ($500K revenue) |
|---|---|---|
| NOI | Revenue - OpEx | $500,000 - $350,000 = $150,000 |
| DSCR | NOI / Debt Payments | $150,000 / $80,000 = 1.875x |
| Cash-Basis DSCR | (NOI + D&A) / Debt | $170,000 / $80,000 = 2.125x |
| Max Debt at 1.25x | NOI / 1.25 | $150,000 / 1.25 = $120,000 |
| Breakeven Revenue | OpEx + Debt | $350,000 + $80,000 = $430,000 |
DSCR Benchmarks by Lending Sector in 2026
Different lenders and loan types have varying DSCR requirements. Understanding where your ratio falls helps you target the right financing:
| Lending Sector | Typical Minimum DSCR | Notes |
|---|---|---|
| Conventional Commercial RE | 1.25x -- 1.35x | Long-term, asset-backed loans |
| SBA Loans | 1.15x -- 1.25x | More flexible with strong collateral |
| Project Finance | 1.4x -- 2.0x | Higher due to cash flow uncertainty |
| Equipment Financing | 1.20x -- 1.30x | Secured by the equipment itself |
| Lines of Credit | 1.10x -- 1.25x | Revolving, shorter-term facilities |
A manufacturing company with a 1.875x DSCR would comfortably qualify across all these categories, giving it significant flexibility when choosing financing options.
Worked Example: Manufacturing Company Debt Assessment
A manufacturing company reports $500,000 in annual revenue, $350,000 in operating expenses, $20,000 in depreciation, and $80,000 in annual debt payments. Here is how each metric is derived:
- NOI: $500,000 - $350,000 = $150,000
- DSCR: $150,000 / $80,000 = 1.875x (strong -- exceeds 1.25x minimum)
- Cash-Basis DSCR: ($150,000 + $20,000) / $80,000 = 2.125x
- Excess Cash: $150,000 - $80,000 = $70,000 available after debt
- Max Debt at 1.25x: $150,000 / 1.25 = $120,000 (room for $40,000 more)
- Breakeven Revenue: $350,000 + $80,000 = $430,000 (current revenue exceeds by $70,000)
The 1.875x DSCR signals to lenders that this business generates nearly twice the income needed to cover its debt, making it a strong candidate for additional financing.
Strategies to Improve Your DSCR
If your DSCR falls short of lender requirements, focus on the three levers in the formula: revenue, expenses, and debt structure. Even modest changes can move the needle significantly.
For the example business at 1.875x DSCR:
- Reducing expenses by $10,000 raises NOI to $160,000 and DSCR to 2.0x
- Increasing revenue by $20,000 raises NOI to $170,000 and DSCR to 2.125x
- Refinancing to $60,000 annual payments raises DSCR to 2.5x with the same NOI
| Scenario | NOI | Debt Payments | DSCR |
|---|---|---|---|
| Current | $150,000 | $80,000 | 1.875x |
| Cut $10K expenses | $160,000 | $80,000 | 2.000x |
| Add $20K revenue | $170,000 | $80,000 | 2.125x |
| Refinance to $60K | $150,000 | $60,000 | 2.500x |
Lenders view improving DSCR trends favorably, so even incremental gains strengthen your borrowing position over time.
