What DSCR tells a lender
The debt service coverage ratio (DSCR) compares a property's net operating income to its annual debt payments. It answers one question: can this property cover its own mortgage by a comfortable margin?
Annual debt service is the full year of principal and interest payments on the mortgage. Net operating income is the property's rental income after operating expenses but before debt payments.
A DSCR of 1.00 means income exactly equals debt payments, leaving nothing for vacancies, repairs, or margin. Lenders want a cushion, typically 1.25 or higher.
Reading the status labels
This calculator labels the result based on common lender thresholds. A ratio at or above 1.25 is marked healthy, which clears most commercial and rental property lending bars.
Between 1.00 and 1.25 the loan is borderline: a short vacancy or an unexpected repair can push the property under water. Below 1.00 the income does not cover the debt, and most lenders will decline without additional cash or equity.
| DSCR | What it means |
|---|---|
| 1.25 and above | Healthy. Income covers debt with the margin lenders typically accept. |
| 1.00 to 1.24 | Borderline. Covers the payment but leaves little room for setbacks. |
| Below 1.00 | Too low. Income falls short of debt service and approval is unlikely. |
Using DSCR in your own analysis
Worked example: a rental produces $50,000 in annual net operating income and carries $40,000 in annual debt service. The ratio is 1.25, right at the healthy line.
Raising rent, cutting operating costs, or buying at a lower price all push DSCR up. Adding debt, or borrowing at a higher rate, pushes it down. You can test each lever here before approaching a lender.
