Debt Yield Calculator: NOI as a Share of Loan Amount

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Debt yield | Non-yield share |
|---|---|---|
| $120k NOI · $1.5M loan | 8.00% | 92.00% |
| $80k NOI · $1M loan | 8.00% | 92.00% |
| $450k NOI · $5M loan | 9.00% | 91.00% |
| $60k NOI · $1M loan (stretch) | 6.00% | 94.00% |
How This Calculator Works
Enter annual NOI and the loan amount. The calculator divides one by the other and multiplies by 100 to give debt yield, with the complement shown alongside. The figure is independent of interest rate and term, which is why CMBS lenders use it as a backstop test alongside LTV and DSCR.

Part is the portion, Whole is the total it belongs to
Worked Example
A property with $120,000 of NOI against a $1,500,000 loan posts an 8% debt yield. CMBS underwriting commonly targets 8% to 10% minimum debt yield; under 8% signals the loan is too large relative to the income stream, regardless of how the LTV looks on a momentarily high appraisal.
Key Insight
Debt yield rose to prominence after the 2008 financial crisis exposed how LTV and DSCR could be gamed in low-rate environments — both improve when rates fall, even if NOI is stagnant. Debt yield ignores rates entirely: it asks 'how much income does this loan produce relative to its size?' A 6% debt yield is a 6% debt yield whether rates are 3% or 8%.
Why debt yield replaces LTV in modern lending
Pre-2008 commercial real estate lending focused on Loan-to-Value (LTV) ratio — typically 75-80% maximum. The 2008 financial crisis revealed LTV's flaw: when property values fell, LTV ratios that looked safe became unsafe through no fault of the borrower (LTV calculated against inflated 2007 valuations was 75%; against 2009 values became 100%+).
Post-2008, the industry shifted to debt yield as the primary underwriting metric. Debt yield is calculated against actual NOI, not against appraised value (which is subject to subjective assumptions). At 10% debt yield, the loan is supported by genuine current income regardless of valuation assumptions. This made underwriting more conservative and stable.
Lender requirements 2024 (post-COVID rate normalization): minimum debt yield 8-9% for stabilized multifamily and industrial; 9-11% for office (reflecting work-from-home risk); 10-12% for hotels and self-storage. As interest rates rose 2022-2024, debt yield requirements tightened — borrowers need to bring more equity to deals (lower LTV) to meet debt yield minimums.
Debt yield, DSCR, and cap rate — three views of the same risk
Debt yield, debt service coverage ratio (DSCR), and cap rate spread are all measures of CRE lending safety, each emphasizing different aspects. DEBT YIELD = NOI / debt — measures income coverage of debt regardless of interest rate. Independent of rate environment.
DSCR = NOI / annual debt service — measures income coverage of actual payments. Sensitive to interest rate; loan with 6% interest has higher DSCR than same loan at 10% interest for same NOI. Standard CRE minimum: 1.25× DSCR.
CAP RATE SPREAD = cap rate − interest rate — measures whether the property's yield exceeds debt cost. Positive spread = positive-leverage; negative spread = negative-leverage. As interest rates rose 2022-2024, many deal cap rate spreads compressed to zero or negative, meaning leverage no longer enhances returns. This is why CRE deal flow slowed materially during 2023-2024 — many sponsors couldn't underwrite deals to acceptable returns at high financing costs.
Commercial real estate lender debt yield requirements (2024)
Reference minimum debt yield requirements by property type and risk category. Higher debt yield required for riskier properties.
| Property type | Minimum debt yield (stable) | Minimum debt yield (transitional) | Notes |
|---|---|---|---|
| Multifamily (Class A) | 8-9% | 9-10% | Lowest risk |
| Multifamily (Class B/C) | 9-10% | 10-12% | |
| Industrial / logistics | 8-9% | 10-12% | Strong sector |
| Retail (grocery-anchored) | 9-10% | 11-13% | |
| Office (CBD class A) | 9-11% | 12-15% | Elevated risk |
| Office (suburban / older) | 11-13% | 14-18% | High risk |
| Hotels (full-service) | 10-12% | 12-15% | Volatility |
| Self-storage | 9-11% | 11-13% | |
| Healthcare (medical office) | 8-10% | 10-12% |
Lender debt yield requirements rose 100-300 basis points from 2021 to 2024 as interest rates increased. Office sector minimums rose most dramatically reflecting work-from-home demand uncertainty. For deals to close at acceptable debt yield, borrowers brought more equity (lower LTV) than in 2021 — typical LTV for multifamily fell from 70% to 60-65% in this period.
Frequently Asked Questions
How is debt yield calculated?
Divide annual NOI by the loan amount, then multiply by 100. $120,000 of NOI on a $1.5M loan is an 8% debt yield.
Why use debt yield instead of LTV or DSCR?
LTV depends on appraisal (which can spike with low rates); DSCR depends on interest rate (which inflates DSCR when rates are low). Debt yield uses only NOI and loan balance — neither can be gamed by financing assumptions.
What is a healthy debt yield?
CMBS lenders commonly underwrite to 8% to 10% minimum debt yield. Class A office and apartments often clear 10%+; tertiary markets and stretch loans frequently sit below 8%. The threshold varies by property type and market.
How is debt yield used in loan sizing?
Lenders set a minimum debt yield (e.g. 9%) and back into the maximum loan size: max loan = NOI / minimum debt yield. A property with $120k NOI under a 9% minimum supports at most $1.33M of debt regardless of LTV.
Is debt yield used outside commercial real estate?
Rarely. The metric is specific to commercial real estate, particularly conduit (CMBS) lending. Corporate debt uses interest coverage and leverage ratios; consumer mortgages use LTV and DTI.
When is this calculator unreliable?
When NOI is calculated inconsistently with the lender's methodology (some lenders include reserves, others don't), for transitional or value-add properties where pro-forma NOI exceeds current NOI (lenders typically underwrite to current NOI for debt yield), or for properties with materially seasonal income (hotels, ski resorts, agricultural) where annual NOI smooths out monthly volatility that the lender may discount.

Methodology & Review
Debt yield equals net operating income (NOI) / loan amount × 100. The calculator returns debt yield as a percentage. Debt yield is the commercial real estate lender's key risk metric — it measures how much income the property generates per dollar of debt independent of interest rate. A 10% debt yield means the property generates $0.10 of NOI per dollar of debt. Standard CMBS lender requirements 2024: minimum 8-9% debt yield for stabilized commercial properties; 9-11% for transitional/value-add; 10-12% for hotels and other higher-volatility assets. RELIABILITY: Reliable for stable income properties. Less reliable for properties with NOI growing rapidly (debt yield will improve over time but starts low), for value-add deals where pro-forma NOI exceeds current NOI, or for transactional purposes where 'NOI' definitions vary between lenders.
