What Is Debt Yield? The Ratio That Caps Your Loan

Debt yield is a property's annual net operating income divided by the loan amount. Commercial lenders run it alongside loan-to-value and debt service coverage. On a lot of deals it produces the smallest of the three numbers, which makes it the test that sets your loan size.

Most explainers stop at the formula. The part that decides your deal is which of the three tests binds first.

What is debt yield?

The federal banking regulator that supervises national banks defines it the same way. The Office of the Comptroller of the Currency's Commercial Real Estate Lending booklet, version 2.0, calls debt yield the ratio of NOI to debt. It is calculated by dividing NOI by the loan amount, with the quotient expressed as a percent.

That paragraph is the whole reason the ratio exists.

How to calculate debt yield

The formula has two inputs.

Debt yield = annual net operating income ÷ loan amount × 100

Net operating income is the property's gross income less operating expenses. The OCC booklet's definition decides what belongs in that numerator. Gross income covers rents plus other income such as parking, laundry, and vending.

Operating expenses exclude interest, principal, income taxes, and depreciation. They do include a replacement reserve, which the booklet says is "imputed for underwriting purposes irrespective of whether it is actually funded."

Two things follow from that definition. Your mortgage payment never appears in NOI, so the ratio is blind to your loan's rate and amortization schedule. A replacement reserve gets deducted whether or not you fund one. That is a common reason a borrower's NOI and a lender's NOI differ before anyone argues about vacancy.

A worked example, using a 24-unit apartment building:

• Stabilized NOI: $480,000
• Loan request: $6,000,000
• Debt yield: $480,000 ÷ $6,000,000 = 8.0 percent

Run the same formula backward to size a loan. If the lender's floor is 10 percent, divide NOI by 0.10:

• Maximum loan at a 10 percent debt yield: $480,000 ÷ 0.10 = $4,800,000

The $6 million request fails a 10 percent test by $1.2 million, and no amount of rate shopping changes that.

Who uses debt yield

• Banks and credit unions underwriting permanent loans on income-producing property, usually as an internal policy floor rather than a published requirement.
• CMBS conduit lenders, where debt yield has been a standard sizing and stratification metric since the market rebuilt after 2008.
• Life insurance companies and debt funds, whose floors vary widely by strategy and by how stabilized the asset is.
• Bank examiners, who use it to compare loan risk across a portfolio without adjusting for each loan's rate and amortization.

If you are financing a single rental rather than a commercial building, the equivalent conversation is usually about coverage instead. Our walkthrough of what a DSCR loan is covers how those lenders size smaller deals.

Debt yield vs. DSCR vs. LTV: which one caps your loan

A commercial lender that runs all three tests sizes the loan three ways and lends the smallest result. Watch what happens to the same property when only the interest rate moves.

The building: $480,000 stabilized NOI, $8,000,000 appraised value. The lender's tests: 65 percent maximum LTV, 1.25x minimum DSCR, 10 percent minimum debt yield, 30-year amortization.

At 6.75 percent the three tests land within $400,000 of each other and debt yield wins by a nose. Drop the rate 150 basis points and the DSCR test suddenly supports $5.79 million, which is more than even the LTV cap allows. The debt yield test does not move at all, because neither of its inputs changed.

That is the practical difference. DSCR and LTV both relax in a falling-rate, rising-value market. Debt yield is anchored to in-place income and the dollars you borrowed, so it holds the line when the other two drift.

The approved $4.8 million loan works out to a 60 percent LTV and a 1.28x DSCR at the higher rate. Both of those look comfortable on a term sheet. The borrower who assumed 65 percent leverage and budgeted equity accordingly is still $400,000 short at closing.

Debt yield vs. cap rate

These two get confused because they share a numerator. Cap rate divides NOI by the property's value; debt yield divides the same NOI by the loan. Cap rate describes the asset, debt yield describes the lender's exposure to it.

A property can trade at an aggressive 4.5 percent cap rate and still fail a 10 percent debt yield test. A low cap rate means a high value, and a high value invites a bigger loan than the income supports.

What debt yield do lenders require?

This is where most of the internet is quoting a rescinded document.

Version 1.1 of the OCC's Commercial Real Estate Lending booklet was issued in January 2017. It called 10 percent "generally considered a minimum acceptable yield," with higher yields recommended for riskier properties. That line is the source of the 10 percent figure repeated across lender blogs and glossary pages.

OCC Bulletin 2022-7, dated March 29, 2022, replaced that booklet with version 2.0 and rescinded version 1.1. The current text drops the number. It now says only that debt yields vary according to market conditions and property types. The regulator also softened the surrounding sentence, from must be considered alongside other criteria to should.

So there is no supervisory debt yield minimum in force today. Loan-to-value is different, because a published supervisory table still applies to it. The Interagency Guidelines for Real Estate Lending set these supervisory LTV limits:

• Raw land: 65 percent
• Land development or improved lots: 75 percent
• Commercial, multifamily, and other nonresidential construction: 80 percent
• Improved commercial, multifamily, and other nonresidential property: 85 percent

Debt yield has no equivalent table. That is why floors differ so much from one lender to the next.

Market data is the better reference point. Trepp's analysis of CMBS issuance reported that conduit loans originated in 2026 through July carried a 13.20 percent average debt yield, a 58.5 percent LTV, and a 1.89x DSCR. Multifamily arrived at the thinnest debt yield of any major property type, at 8.20 percent.

The refinance side of that market shows why the ratio gets attention.

A loan written at a thin debt yield in a low-rate year comes due at a higher rate against the same income. The coverage test that approved it originally may no longer support the same balance. That leaves a paydown, a restructuring, or a sale.

Bank appetite matters too. In the Federal Reserve's July 2026 Senior Loan Officer Opinion Survey, banks reported easing standards at the margin on nonfarm nonresidential and multifamily loans. Moderate net shares still described their standards for those categories as relatively tight against their historical range. Easing from a tight starting point is still a tight starting point.

How to prepare for the debt yield test

Only two levers exist, and they are not equally fast.

Defend the numerator. Debt yield is only as good as the NOI an underwriter accepts. That figure is almost always lower than the one on the owner's operating statement. Deliver a rent roll that reconciles to the trailing twelve months, because a gap between annualized contract rent and collected income invites a haircut on both. Our breakdown of how lenders read a rent roll covers the specific adjustments to expect.

Strip income the lender will strike anyway. One-time reimbursements, a related-party lease at above-market rent, and income from a unit occupied by an on-site manager tend to come out. Removing them yourself before submission is better than having them found.

Size the request to the test. If the 10 percent floor supports $4.8 million and you need $5.4 million, the $600,000 gap is equity. Lenders verify that equity, plus post-closing liquidity, on a personal financial statement, so build the number into your equity plan early. A current personal financial statement is what documents it, and SBA borrowers file the same information on Form 413, which our SBA Form 413 guide walks through section by section.

Ask which test binds. A good loan officer will tell you. The answer determines whether a better rate helps you at all: if debt yield is the binding test, shopping rate lowers your payment without raising your proceeds by a dollar.

What debt yield means for your deal

Debt yield answers one question: how much income stands behind every dollar of the loan. It is the least flattering of the three sizing tests in a strong market, and the most stable one when conditions turn. Lenders kept using it after the regulator stopped naming a number. Find out your lender's floor before you set your equity budget, and treat any 10 percent figure you read online as a market convention rather than a rule.
