🏦 Debt Service Coverage Ratio Calculator
A DSCR calculator that computes NOI ÷ annual debt service and checks it against the 1.25x threshold most commercial and DSCR-loan lenders require.
What Debt Service Coverage Ratio Calculator Does
DSCR answers one specific question: does the income a property or business generates actually cover its debt payments, with room to spare? It deliberately ignores the price paid for the asset or how it was financed — a highly leveraged purchase and an all-cash purchase of the same property produce the same DSCR, because the ratio only looks at income versus debt payments, not capital structure.
Lender minimums cluster in a fairly narrow, well-documented range. Investopedia reports many lenders set minimum DSCR requirements between 1.2 and 1.25, with a ratio above 1.25 generally considered strong and 2.00 or higher considered very strong, though there is no single industry-wide standard — the actual minimum in any specific loan agreement depends on the lender and loan type.
How to Use Debt Service Coverage Ratio Calculator
- Enter annual gross rental or operating income
- Enter annual operating expenses (not including debt payments)
- Enter total annual debt service (principal + interest) to see the DSCR and how it compares to typical lender minimums
Formula Used by Debt Service Coverage Ratio Calculator
Debt Service Coverage Ratio
DSCR = Net Operating Income ÷ Total Annual Debt Service
- NOI
- Gross income minus operating expenses, before debt payments
- Total Annual Debt Service
- All principal and interest due in the period, including any sinking fund payments
Worked example
$180,000 gross income, $65,000 operating expenses, $92,000 annual debt service
- NOI: $180,000 − $65,000 = $115,000
- DSCR: $115,000 ÷ $92,000
Result: 1.25 — meets typical lender minimums
DSCR reference bands
Commonly cited bands; the specific minimum in any loan agreement is set by the individual lender.
| DSCR | General read |
|---|---|
| Below 1.00 | Negative coverage — income does not cover debt payments |
| 1.00–1.24 | Positive but thin cushion; below many lenders' minimum |
| 1.25–1.99 | Commonly cited as a strong, bankable range |
| 2.00+ | Typically considered very strong — no universal standard, but a common informal benchmark |

How to Read Your Result
DSCR says nothing about return on investment
A property can clear a lender's DSCR minimum comfortably and still be a mediocre investment, or vice versa — DSCR measures debt safety, not profitability. Pair it with a cap rate or cash-on-cash return calculation to see the investment-return side.
Limitations & Accuracy Notes
- This uses net operating income before taxes and interest deductions; a more precise lender calculation may adjust total debt service for the tax-deductibility of interest.
- Lender minimums vary by loan type and property class — the 1.25 reference figure is a common range, not a universal rule, and does not apply identically to every loan program.
- Does not account for vacancy reserves, capital expenditure reserves, or other underwriting adjustments a specific lender may require beyond the basic NOI/debt-service ratio.
