Debt Yield Ratio Calculator
Commercial lenders ask one blunt question before approving a loan: if we foreclosed tomorrow and operated this property ourselves, what would we earn on the loan amount? The debt yield ratio answers it with a single division, net operating income over loan amount, and it ignores interest rates entirely. This debt yield ratio calculator computes yours, tests it against a lender minimum you choose, and shows the maximum loan the property income can support at that minimum.
Quick Answer
A property with $480,000 of net operating income and a $4,000,000 loan has a 12.00% debt yield, comfortably above the 10% floor most CMBS lenders require. At that 10% minimum, the income supports up to $4,800,000 of debt, leaving $800,000 of borrowing headroom. Because the ratio ignores interest rates, it cannot be improved with cheaper financing.
How to use this calculator
The direct answer: enter annual NOI, the loan amount, and the minimum yield your lender requires, then press Calculate Debt Yield. Use NOI on the same basis your lender will underwrite, which usually means trailing-12-month actuals after operating expenses and before debt service and taxes. A projected NOI that has not materialized will flatter the result and then fail at underwriting, so enter the defensible figure first and run the optimistic one second, if at all.
Results stay hidden until you calculate, and Reset restores the worked example. The verdict badge reads the tool’s own bands: 10% or higher is Strong, 8% to below 10% is Borderline, below 8% is Weak. Those bands are a reading of market practice, not a published rule, and your lender’s term sheet overrules them. The maximum loan line is the figure to negotiate around, but it is only this test’s answer: loan-to-value and DSCR can still cut the loan below it.
Formula
The direct answer: debt yield equals NOI divided by loan amount, times 100, and the maximum loan at a minimum equals NOI divided by that minimum as a decimal. Both formulas use the same two inputs, which is why the tool can run forward to a yield and backward to a loan size in one click.
Debt yield = NOI / loan amount x 100. Maximum loan = NOI / (minimum yield / 100). Headroom = maximum loan minus proposed loan, and when headroom is zero or negative the tool reports “No headroom” rather than a negative dollar figure. That wording is deliberate: a negative headroom number would look like an amount you could borrow, when it is really an amount you must cut.
Worked example: $480,000 of NOI on a $4 million loan
The defaults above reproduce this exactly when you press Calculate. First, confirm the NOI: $480,000 of annual net operating income, after operating expenses, before debt service and taxes. Second, divide by the loan: $480,000 / $4,000,000 = 0.12 = 12.00% debt yield. Third, test the minimum: 12% clears the 10% CMBS floor, so the loan passes this screen. Fourth, size the maximum loan: $480,000 / 0.10 = $4,800,000, which is $800,000 of headroom above the proposed loan.
| Step | Arithmetic | Result |
|---|---|---|
| Debt yield | 480,000 / 4,000,000 x 100 | 12.00% |
| Maximum loan | 480,000 / 0.10 | $4,800,000 |
| Headroom | 4,800,000 – 4,000,000 | $800,000 |
| Implied foreclosure cap rate | Same figure, different reading | 12.00% |
The implied foreclosure cap rate equals the debt yield (12%), since a foreclosing lender effectively buys the property for the loan balance. If that implied cap rate looks rich against market cap rates, the lender has downside protection. If it looks thin, the lender is paying a full price for a troubled asset, and the yield alone will not save the deal.
Debt yield vs DSCR: the two lender screens side by side
The direct answer: debt yield tests the loan balance, DSCR tests the payments, and a loan needs to pass both. Both ratios use NOI, but they interrogate the loan from opposite directions, and that difference is the whole reason lenders run them together.
| Debt yield (this calculator) | DSCR | |
|---|---|---|
| Divides NOI by | Loan amount | Annual debt service |
| Moves with rates? | No | Yes |
| Moves with amortization? | No | Yes |
| Viewpoint | Lender foreclosure return | Borrower payment capacity |
A loan can pass DSCR and fail debt yield: cheap floating-rate debt makes payments look easy while the income-to-loan cushion stays thin. That is the structure that burned lenders in past cycles, which is why most term sheets now require both. For the investor side of the same deal, our cap rate calculator divides the same NOI by property value instead of loan amount, and the contrast between the two answers is often the most useful number in the negotiation.
Lender minimums by property type
The direct answer: there is no single published minimum, but market practice clusters around 8% for multifamily, 10% for retail, and 12% for office, with the calculator’s 10% CMBS line as its green band. Treat every figure in this table as a starting point for a lender conversation, not as a term sheet, because minimums move with the cycle, the market, and the sponsor.
| Property type | Typical minimum in market practice | Why it differs |
|---|---|---|
| Multifamily | Around 8% | Sticky rents, diversified tenants |
| Retail | Around 10% | Anchor-tenant and e-commerce risk |
| Office | Around 12% | Vacancy and work-from-home overhang |
| Worked example | 12.00% actual | Clears all three bars on this test alone |
Debt funds and bridge lenders often demand more than banks, and every lender pairs the yield test with DSCR, loan-to-value, and borrower credit. A 12% debt yield with a thin DSCR still gets a hard look. The leverage side of the same deal is covered by our debt to capital ratio calculator for capital structure and our debt to EBITDA ratio calculator for earnings coverage, which answer different leverage questions from this lender cushion test.
What competing calculators miss
The direct answer: most rival tools divide two numbers and stop, which misses the entire point of the metric. The thin tools in this space never test the result against a lender minimum, never work backward to the maximum supportable loan that borrowers actually negotiate around, and never show the implied foreclosure cap rate that lets a lender sanity-check the collateral value. Several also bury the rate-independence point, leaving users to wonder whether they entered the interest rate in the wrong box.
This calculator adds the minimum test, the reverse loan sizing, the cap-rate reading, and the rate-independence note on every result. It also says plainly what it does not do: it does not compute DSCR, it does not test loan-to-value, and it does not underwrite the borrower. A tool that pretended to approve a loan from one ratio would be worse than a thin tool, because it would be confident and wrong. If you need the full loan picture, run this test first for sizing, then a commercial mortgage calculator for the payments that DSCR will test.
Key takeaway: Debt yield moves only with income or loan size. If you want a bigger loan at the same minimum, raise the NOI or bring more equity; no change in rate, term, or amortization will move it.
Frequently asked questions
10% or higher satisfies most CMBS lenders and counts as strong in this tool’s verdict bands. From 8% to below 10% is borderline and depends on property type and lender, and below 8% is weak and usually means a smaller loan or a declined application. Those bands are this tool’s reading of market practice, not a rule published by any single regulator.
Cap rate divides NOI by property value, while debt yield divides NOI by loan amount. They coincide only if the loan equals the value. Debt yield is the lender’s lens, because it measures income against the loan at risk, and cap rate is the investor’s lens, because it measures income against the price paid.
No, deliberately. It is independent of rates, amortization, and loan terms, which is why lenders trust it: a borrower cannot improve it with cheaper financing, only with more income or less debt. That is also why it must sit next to DSCR, which does test whether payments can be made.
DSCR compares NOI to annual debt service, so it moves with rates and amortization. Debt yield compares NOI to the loan balance, so it does not. Lenders typically require both, because a loan can pass the payment test while failing the cushion test.
Lenders prefer trailing-12-month actuals and haircut projections. Some accept stabilized pro-forma NOI for value-add deals, usually with a lower loan until the income materializes. Enter the NOI your lender will actually underwrite, not the best-case rent roll.
No. It is a commercial real estate underwriting metric. Residential lending uses debt-to-income, loan-to-value, and credit scores instead, because a home loan is underwritten on the borrower’s income, not on a property’s operating income.
The lender typically offers a smaller loan, which raises the yield, prices the loan wider, or declines. A borrower can respond with more equity, which shrinks the loan and lifts the ratio, or with a smaller purchase price on the same income.
Divide NOI by the lender’s minimum yield as a decimal: $480,000 divided by 0.10 is $4,800,000. That is the largest loan that still clears the bar on this test alone, before loan-to-value and DSCR constraints cut it back.
After the 2008 crisis, regulators and CMBS investors wanted a metric that aggressive loan structuring could not flatter. Debt yield filled that gap because only income and loan size move it, so interest-only periods and long amortizations leave it unchanged.
No. It is one screen among several: DSCR, loan-to-value, borrower credit and experience, property condition, and market all matter. A strong debt yield with weak sponsorship or a troubled tenant roster still gets declined.
