Debt Yield Calculator

Debt yield is the simplest of the three loan-sizing tests in commercial real estate: Debt Yield = Net Operating Income ÷ Loan Amount, expressed as a percentage. A property producing $450,000 of NOI against a $5,000,000 loan has a debt yield of 9.0%. Rearranged, the maximum loan a lender will fund is Loan = NOI ÷ Target Debt Yield, so at a 9.0% requirement that same $450,000 NOI supports exactly $5,000,000.

What makes debt yield distinctive is what it leaves out. It contains no interest rate, no amortization schedule, no cap rate, and no appraised value. It is purely the relationship between the income the asset throws off and the dollars the lender has at risk. Read literally, a 9% debt yield says that if the lender took the keys tomorrow and operated the property, it would recover 9% of its loan balance every year from operations alone.

That immunity to assumptions is exactly why debt yield became a standard underwriting test after the 2008 credit crisis. In the 2005 to 2007 cycle, lenders sized loans on DSCR and LTV, both of which could be inflated: DSCR by interest-only periods and 30-year or 40-year amortization schedules, and LTV by aggressive appraisals struck off compressed cap rates. Debt yield cannot be manipulated by either lever, because neither appears in the formula.

CMBS conduits, life companies, debt funds, and most balance-sheet banks now publish a minimum debt yield alongside their DSCR and LTV requirements. The loan a borrower actually receives is the smallest of the three constraints, which is why sizing a deal means computing all three and taking the minimum, not picking the friendliest one.

Take a stabilized suburban retail center with $450,000 of NOI, an appraised value of $7,500,000 (a 6.0% cap rate), and a lender quoting 6.75% on a 30-year amortization. The lender's stated constraints are 9.0% minimum debt yield, 1.25x minimum DSCR, and 70% maximum LTV.

The LTV test allows 70% of $7,500,000, or $5,250,000. The debt yield test allows $450,000 ÷ 0.09 = $5,000,000. The DSCR test requires that NOI ÷ annual debt service be at least 1.25, which means annual debt service can be no more than $360,000. At 6.75% over 30 years, the constant is roughly 7.784% of the loan balance per year, so the loan cannot exceed 360,000 ÷ 0.07784, about $4,625,000.

The binding constraint here is DSCR at roughly $4.63 million, not debt yield or LTV. The borrower requested $5.25 million and will be offered $4.6 million, meaning $650,000 more equity than they modeled. This is the single most common surprise in commercial financing, and it appears in the term sheet at the worst possible moment.

Now change one variable. Suppose rates fall to 5.25%. The constant drops to about 6.63%, so the DSCR test allows 360,000 ÷ 0.0663, roughly $5,430,000. LTV still caps at $5,250,000, and debt yield still caps at $5,000,000. Debt yield is now the binding constraint. This is exactly the behavior lenders wanted: as cheap debt makes DSCR and LTV permissive, debt yield holds the line on absolute leverage.

Debt yield minimums move with the credit cycle and with perceived asset risk. The ranges below reflect what borrowers have generally seen in the United States in the mid-2020s; every lender publishes its own grid and adjusts quarterly.

Stabilized multifamily with agency debt (Fannie Mae, Freddie Mac): 7.0% to 8.5%. The agencies accept the lowest debt yields in the market because of the depth and stability of apartment demand.

Bank and life-company loans on stabilized industrial or grocery-anchored retail: 8.5% to 10.0%.

CMBS conduit loans on general commercial property: 9.0% to 11.0%, with 10% a frequent floor for anything without long-term credit tenancy.

Office: 11.0% to 13.0% and often higher since 2023. Lenders have repriced office risk sharply, and the debt yield test is where that repricing shows up most visibly.

Hotels: 11.0% to 14.0%, reflecting daily-repricing revenue and operating intensity.

Construction and bridge loans on unstabilized assets: lenders typically apply a stabilized debt yield test at the exit, often 9% to 12%, because there is no current NOI to divide.

A useful mental model: the debt yield floor tends to sit roughly 250 to 400 basis points above the going-in cap rate for the same asset class. When that spread compresses, lending is loose. When it widens, credit is tightening and refinancing risk is rising across the market.

Loan-to-value measures the lender's cushion against a decline in value. Its weakness is that value is an opinion produced by an appraisal, and appraised value is highly sensitive to the cap rate selected. A 50 basis point difference in cap rate assumption can move value by 8% or more, which moves the permitted loan by the same proportion.

Debt service coverage ratio measures the cushion between income and required payments. Its weakness is that the payment is a function of rate, amortization term, and interest-only structure, all negotiable. A borrower can manufacture DSCR compliance simply by requesting a 40-year amortization or a three-year interest-only period, without changing the property at all.

Debt yield measures the cushion between income and loan dollars directly, with no assumptions in between. Its weakness is the mirror image of its strength: because it ignores rate, it can be punitive in a low-rate environment where a property comfortably covers its payments but still cannot reach the debt yield floor.

There is a clean relationship between the three. Debt Yield = Cap Rate ÷ LTV whenever value is derived by capitalizing the same NOI. At a 6% cap rate and 70% LTV, the implied debt yield is 6 ÷ 0.70 = 8.57%. If a lender requires 9%, the maximum LTV it can actually fund on that cap rate is 6 ÷ 9 = 66.7%, regardless of what its LTV grid says. Borrowers who understand this relationship can predict a term sheet before it arrives.

Raise NOI, not value. Because value never appears in the formula, an appraisal that comes in high does nothing for debt yield. Only income does. Signing a vacant suite, converting a gross lease to triple net, adding recoverable expenses, or capturing below-market renewals all move the numerator.

Scrub the expense side before submission. Lenders underwrite to their own expense assumptions, including a management fee even for self-managed owners and a per-unit or per-square-foot replacement reserve. Submitting a statement without these invites the lender to insert its own, usually less favorable, numbers.

Reduce the loan request. It is arithmetic: less leverage produces higher debt yield. If the deal is short by 60 basis points of debt yield, the required loan reduction is roughly that shortfall divided by the target, applied to the requested amount.

Use an earnout or holdback structure. Many lenders will fund the debt-yield-compliant amount at closing and release additional proceeds later when NOI reaches a stated threshold, giving the borrower most of their leverage without breaching the test on day one.

Do not rely on pro-forma NOI. Debt yield is computed on underwritten in-place income, typically trailing twelve months adjusted for lender assumptions. Projections about next year's rent roll almost never count toward the numerator.

Watch the refinance horizon. A loan that barely cleared a 9% debt yield at origination will fail at maturity if NOI has been flat and the market's debt yield floor has risen to 11%. Modeling the exit debt yield, not just the entry, is the discipline that separates operators who refinance smoothly from those who face a capital call.
