DSCR divides a property's net operating income by its annual debt service, showing how much cushion exists above the loan payment. Debt yield divides net operating income by the loan amount, showing the lender's return if it had to foreclose and hold the asset today. DSCR is sensitive to interest rate and amortization; debt yield is not, which is why many lenders now use debt yield as a floor alongside DSCR.

In Depth
Debt service coverage ratio (DSCR) divides a property's net operating income by its total annual debt service, the sum of principal and interest payments due on the loan. A DSCR of 1.25x means the property generates 25% more income than it needs to cover its debt payments, giving the lender a cushion against vacancy, expense increases, or a soft market. DSCR is the most widely used underwriting metric for permanent and stabilized-asset loans, because it directly tests whether the property's actual cash flow can service the specific loan being underwritten, rather than relying solely on collateral value.
DSCR requirements typically range from 1.20x to 1.35x depending on property type, market, and lender, with more conservative ratios required for higher-risk asset classes such as hotels or for markets with less liquidity. Because debt service depends on both the interest rate and the amortization schedule, DSCR moves whenever rates change or a lender adjusts the amortization period. A loan sized to a strong DSCR at a 5% rate can look materially weaker if rates rise or if the lender shortens amortization from 30 years to 25, even though the property's income has not changed.
The main limitation of DSCR is that it can be manipulated by loan structure rather than property fundamentals. Interest-only periods, longer amortization, or a lower rate can all inflate DSCR without the underlying asset actually generating more income or being worth more. This is part of why many lenders, particularly in the CMBS market, began layering a debt yield test on top of DSCR after the 2008 financial crisis, since debt yield strips out the effect of rate and amortization entirely and tests the loan against income alone.
In Depth
Debt yield divides a property's net operating income by the total loan amount, expressed as a percentage. Unlike DSCR, debt yield ignores the interest rate and amortization schedule entirely: it asks a simpler question, what return would the lender earn on its outstanding balance if it foreclosed today and held the property as an all-cash owner. A debt yield of 9% means the lender's return on its own capital, absent any financing, would be 9% based on current income.
Debt yield became a standard underwriting tool after the 2008 financial crisis, when lenders realized that DSCR alone could support loan amounts that left too little equity cushion if property values fell. Most lenders now target a debt yield floor in the 8-10% range for permanent loans, and use it as a sizing constraint alongside LTV and DSCR, taking whichever test produces the lowest loan amount. Because debt yield is rate-agnostic, it protects the lender even in a rising rate environment where DSCR-based proceeds would otherwise increase.
Debt yield has its own limitation: it says nothing about whether the borrower can actually make the loan payments, since it ignores debt service entirely. A loan could pass a debt yield test comfortably while still failing a DSCR test if the rate is high or amortization is short. For this reason, sophisticated lenders and sponsors run both tests together, treating debt yield as a floor on loan proceeds and DSCR as a check on whether the resulting payment is actually serviceable.
Key Differences
Formula: DSCR compares income to debt service; debt yield compares income to loan amount.
Rate sensitivity: DSCR changes with interest rate and amortization; debt yield does not.
Purpose: DSCR tests whether cash flow covers the payment; debt yield tests the lender's return if it had to foreclose.
Origin: DSCR has long been standard; debt yield gained prominence after the 2008 crisis as a rate-agnostic backstop.
Sizing: Lenders often size to the lower loan amount produced by DSCR, debt yield, and LTV together.
Manipulation risk: DSCR can be inflated by interest-only or long amortization; debt yield cannot.

Going deeper
A property generates $1.2 million in net operating income and is being financed with a $15 million loan, illustrative figures only. At an illustrative 6.5% rate amortizing over 30 years, annual debt service runs roughly $1.14 million, producing a DSCR of about 1.05x, below most lenders' 1.20x to 1.25x minimum.
The same $1.2 million of NOI divided by the $15 million loan amount produces a debt yield of 8%, which might clear a lender's 8% floor even though the DSCR test fails. In this scenario the lender sizes the loan down to whatever amount produces a 1.25x DSCR, roughly $12.7 million at the same rate and amortization, well below what the debt yield test alone would have allowed, illustrating why DSCR is frequently the binding constraint when rates are elevated relative to a property's income.
Lower the rate to an illustrative 5% instead and the picture reverses: the same $15 million loan now carries roughly $966,000 in annual debt service, producing a comfortable 1.24x DSCR, close to passing on its own, while the debt yield calculation stays fixed at 8% regardless of the rate change. In a low-rate environment like this one, debt yield is more likely to become the binding constraint precisely because DSCR alone would otherwise allow a larger loan than an all-cash foreclosure return would justify.
DSCR covenants are written directly into the loan agreement as an ongoing test, not just a closing-day calculation, often requiring annual or even quarterly recertification with the right to sweep excess cash flow into a reserve account if the ratio falls below a specified trigger. This makes DSCR a live, recurring compliance obligation throughout the loan term.
Debt yield is more commonly used as a one-time sizing test at origination, particularly in CMBS loan documents, rather than an ongoing covenant, though some lenders do include a debt yield trigger as an additional cash management event alongside DSCR. Sponsors reviewing loan documents should check whether debt yield appears only in the sizing calculation or whether it also functions as an ongoing covenant with its own remedies, since a debt yield trigger tucked into the cash management section can activate a lockbox sweep well before a DSCR covenant would.
When interest rates rise, DSCR-based loan sizing tightens automatically, since the same NOI now supports less debt at a higher rate, while debt yield, being rate-agnostic, does not move at all in response to the same rate increase. In a rising-rate environment, DSCR frequently becomes the binding constraint even on deals where debt yield alone would have supported a larger loan.
When rates fall, DSCR-based proceeds increase for the same NOI, which is exactly the scenario debt yield was designed to guard against: a lender relying only on DSCR in a low-rate environment could size a loan that represents an uncomfortably thin equity cushion relative to the property's actual income, which is why debt yield became a standard backstop after the 2008 financial crisis.
Since lenders test both ratios together, the useful diligence is understanding which one will actually constrain proceeds on a specific deal, not choosing a single preferred metric.
Our Role
H Equities evaluates both DSCR and debt yield when structuring bridge and mezzanine loans, even though bridge assets are often not yet generating the stabilized income that makes these ratios straightforward to calculate. We underwrite to projected income once the business plan is executed, testing debt yield against as-stabilized cash flow and DSCR against the interest-only payment during the loan term, so the capital stack we structure holds up under a range of income and rate outcomes.
FAQ
Each ratio tests something different. DSCR confirms the property's income can cover the specific loan payment, while debt yield tests the lender's return independent of rate and amortization. Using both protects the lender from a loan that looks safe on one measure but weak on the other, particularly when rates move.
Most institutional lenders look for a debt yield in the 8-10% range on permanent loans, with higher-risk property types or less liquid markets pushing that floor higher. Debt yield requirements vary by lender and are typically set deal by deal rather than published as a fixed standard.
Yes. A loan with a low interest rate or long amortization can post a comfortable DSCR while still producing a debt yield below the lender's floor, particularly at higher leverage. This mismatch is exactly why many lenders size proceeds to whichever test is more restrictive.
Yes, though bridge lenders typically apply it to projected, as-stabilized income rather than current in-place income, since the property has not yet reached its target occupancy or rents. This forward-looking approach lets the lender size the loan against where the asset is expected to land.
