Debt Yield Calculator
Calculate debt yield ratio for commercial real estate loans. The lender's stress-test metric beyond LTV and DSCR.
Debt Yield: The Number Wall Street Trusts
Walk into a conversation with a CMBS lender or an institutional debt fund and you will hear them ask about debt yield before they ask about almost anything else. It catches a lot of borrowers off guard, because most people come up through residential lending where loan-to-value is king. On the institutional side, LTV takes a back seat. Debt yield is the number that gets a deal taken seriously, and once you understand why, you will never look at a commercial loan request the same way.
What debt yield actually measures
Debt yield is simple to calculate and that simplicity is the whole point. You take the property's net operating income and divide it by the loan amount.
If a property throws off $500,000 in NOI and the borrower wants a $5,000,000 loan, the debt yield is 10%. What that 10% really represents is the cash-on-cash return the lender would earn if it had to foreclose tomorrow and own the property outright. It answers the only question a lender truly cares about in a downside scenario: if this goes wrong and I end up holding the asset, what is my income relative to the money I put out? Higher is safer.
Why lenders trust it more than LTV
Loan-to-value sounds rigorous, but it leans on an appraised value, and an appraisal is only an opinion of worth at one moment in time. That value is built on a cap rate, and cap rates move with interest rates and market sentiment. When money is cheap and buyers are aggressive, cap rates compress, values balloon, and the same loan suddenly looks conservative on an LTV basis even though nothing about the building's income changed. Then rates rise, cap rates expand, values fall, and a loan that looked safe is suddenly underwater. LTV flattered the deal at exactly the wrong time.
Debt yield ignores all of that. It uses only two hard numbers: the income the property actually produces and the dollars the lender actually advanced. No appraisal, no cap rate, no interest-rate assumption. That is why it held up through the 2008 collapse, when value-based metrics failed spectacularly, and why CMBS desks adopted it as their primary screen afterward. It measures risk the way risk actually behaves, not the way a hot market wishes it would.
Reading the benchmarks
The indicator on this tool reflects the standards institutional lenders apply in practice. A debt yield at or above 10% is the strong, clean number that meets the conventional institutional floor and gets a deal through underwriting without a fight. Between 8% and 10% sits a gray zone: financeable for a high-quality asset in a strong market with an experienced sponsor, but expect scrutiny and possibly a lower loan amount. Below 8% is where deals stall. The lender is being asked to advance so much against so little income that the downside protection has thinned to the point most institutional programs will pass, or will only proceed with significant structure and a haircut to proceeds.
These are not legal thresholds, and they shift somewhat by property type and cycle. Multifamily often clears at slightly lower debt yields than the floor because the income is seen as durable; hospitality and other volatile asset classes get held to higher numbers. The 8% and 10% markers are the widely used reference points, and they are the right place to start.
How debt yield sets your loan ceiling
Run the formula backward and it becomes a sizing tool. If a lender requires a minimum debt yield of 10% and your property produces $500,000 in NOI, the largest loan that lender will write is the NOI divided by that minimum.
At a 10% floor, $500,000 of NOI supports a $5,000,000 loan and not a dollar more, regardless of what the property might appraise for. This is the calculation that quietly governs how much you can actually borrow on a commercial deal, and it is why two properties with identical values can support very different loan amounts. The one with stronger income wins. The tool shows you this maximum and the headroom between it and what you requested, so you can see immediately whether your ask fits inside the lender's box.
Getting NOI right is the whole game
Because debt yield rests entirely on NOI, the integrity of that number is everything. NOI is gross income minus operating expenses, and it does not include debt service, capital expenditures, depreciation, or income taxes. Lenders underwrite to their own view of NOI, not the seller's pro forma, and they will trim optimistic rent assumptions, normalize expenses that look too low, and add reserves for replacements. A debt yield built on an inflated NOI is fiction, and the lender's analyst will rebuild it from the rent roll and trailing financials. Enter a conservative, defensible NOI here and the result will track much closer to what underwriting actually returns.
Is a higher debt yield always better for the borrower?
A higher debt yield is safer for the lender, which usually means easier approval and better pricing. For the borrower it is a trade-off: a high debt yield often means you are borrowing conservatively relative to the property's income, leaving cash on the table you might have financed. The goal is not to maximize debt yield; it is to land at a number that clears the lender's floor while sizing the loan to what the deal needs.
How does debt yield relate to DSCR?
They are cousins. DSCR — debt service coverage ratio — compares NOI to the actual loan payment, so it depends on the interest rate and amortization. Debt yield compares NOI to the loan balance and ignores the rate entirely. Debt yield is the more conservative screen precisely because a low rate can make DSCR look healthy on a loan that is still too large relative to income. Lenders often check both; debt yield is the one that does not get fooled by cheap money.
What debt yield do CMBS lenders require today?
The common institutional floor sits around 10%, though it moves with the rate environment and the asset class. In higher-rate periods lenders push the minimum up because their own cost of capital is higher; for durable property types like stabilized multifamily they may accept less. Treat 10% as the anchor and confirm the specific floor with the lender or originator on your deal.
Does debt yield change as I pay down the loan?
Yes, and in your favor. Because debt yield is NOI divided by the loan balance, paying down principal raises the debt yield over time even if income stays flat. Growing the NOI does the same. This is why lenders sometimes test debt yield not just at origination but at a future point, to confirm the loan deleverages into a safer position over its term.
Can I use this for a small commercial property?
The math is identical at any size — NOI over loan amount works the same for a $500,000 strip retail loan as for a $50,000,000 office tower. What changes is the lender. Smaller deals are often financed by banks that lean more on DSCR and LTV than on debt yield, while debt yield dominates in the CMBS and institutional world. Use this tool to understand where your deal stands; just know which lender type you are pitching.
