Understanding DSCR: How to Calculate Debt Service Coverage Ratio for Rental Properties
Learn what Debt Service Coverage Ratio (DSCR) is, how commercial lenders evaluate it, and how to calculate it for your next investment property.

Buying a rental property often requires a specialized loan. For real estate investors, a **DSCR (Debt Service Coverage Ratio) loan** is one of the most powerful tools available because it focuses on the property's income rather than your personal salary.
What is DSCR?
DSCR stands for **Debt Service Coverage Ratio**. Lenders use this metric to determine if a property generates enough rental income to cover its monthly mortgage payments (including principal, interest, taxes, insurance, and HOA fees).
The DSCR Formula
Calculating DSCR is straightforward:
**DSCR = Net Operating Income (NOI) ÷ Annual Debt Service**
Or on a monthly basis:
**DSCR = Gross Monthly Rent ÷ Monthly Mortgage Payment (PITIA)**
What Lenders Look For
- **DSCR < 1.0**: The property is "negative cash flowing." The rental income does not cover the mortgage.
- **DSCR = 1.0**: The property breaks even.
- **DSCR > 1.25**: This is the standard benchmark for most lenders. It indicates a healthy buffer of 25% cash flow above the debt obligations.
Example Calculation
Let's say you are buying an investment property: - Gross Monthly Rent: **$2,500** - Monthly PITIA (Mortgage, Tax, Insurance): **$1,900**
**DSCR = $2,500 ÷ $1,900 = 1.32**
Since 1.32 is well above 1.25, this property would easily qualify for a DSCR loan.
