Quick Answer: Debt Service Coverage Ratio (DSCR) measures whether a property's NOI covers its debt payments, and it changes with interest rates and loan terms. Debt yield measures NOI as a percentage of the total loan amount, providing a rate-independent view of lender risk. DSCR is the borrower's coverage cushion; debt yield is the lender's recovery metric.
For a deep dive into each metric individually, see our full DSCR guide and full debt yield guide.
What Is Debt Yield?
Debt yield expresses a property's NOI as a percentage of the loan balance. It tells lenders what return they would receive on their loan amount if they had to take over the property — independent of interest rate, amortization, or loan term.
Example: $1,200,000 NOI ÷ $12,000,000 loan = 10.0% debt yield
What Is DSCR?
Debt Service Coverage Ratio measures NOI relative to the annual debt service (principal + interest payments). It directly answers: can this property make its mortgage payments, and by how much margin?
Example: $1,200,000 NOI ÷ $900,000 debt service = 1.33x DSCR
Key Differences: Debt Yield vs DSCR
| Factor | Debt Yield | DSCR |
|---|---|---|
| Affected by interest rate | No | Yes |
| Affected by amortization | No | Yes |
| What it measures | Lender's yield on loan | Payment coverage cushion |
| Manipulation risk | Low — only two inputs | Higher — adjustable via loan terms |
| Primary users | CMBS, institutional lenders | All commercial lenders |
| Expressed as | Percentage | Ratio (e.g., 1.25x) |
| Typical minimums | 8–10% | 1.20–1.35x |
When to Use Each Metric
Use debt yield when: Comparing loan risk across deals with different interest rates and terms, working with CMBS or institutional lenders who use it as a primary sizing constraint, or evaluating how much risk a lender is taking relative to the loan amount — regardless of financing structure.
Use DSCR when: Assessing whether a property can cover its specific mortgage payments, working with agency lenders (Fannie Mae, Freddie Mac) who use DSCR as the primary constraint, monitoring ongoing loan compliance, or stress-testing a property's ability to service debt if NOI declines.
How They Relate in Practice
Lenders often use both metrics simultaneously, and the more restrictive one determines maximum loan proceeds. A deal might pass the DSCR test at 1.25x but fail the debt yield minimum at 10%. In a low-rate environment, DSCR tends to be less constraining because low interest rates reduce debt service payments. Debt yield remains unchanged because it ignores financing terms entirely.
This is why debt yield gained prominence after the 2008 financial crisis: CMBS lenders realized that DSCR alone could be gamed by extending amortization periods or using interest-only structures. Debt yield provides a financing-structure-agnostic measure of risk. Use our DSCR calculator to model coverage ratios for any loan structure, and see how BubbleGum BI's financial dashboards monitor both metrics with early covenant-violation alerts.
