Debt Yield Calculation: Formula, Examples, and Why Lenders Use It
Debt yield is a lending metric that measures a property's net operating income as a percentage of the total loan amount. It answers a simple question: if the lender had to take back the property today, what annual return would the property's income provide on the loan balance? Commercial lenders increasingly use debt yield alongside DSCR and LTV to evaluate loan risk.
The debt yield formula
Debt Yield = Net Operating Income (NOI) / Total Loan Amount × 100
Example:
NOI: $150,000/year
Loan amount: $1,500,000
Debt yield = $150,000 / $1,500,000 = 10.0%
A 10% debt yield means the property generates income equal to 10% of the loan balance annually. The higher the debt yield, the lower the risk to the lender.
Why lenders care about debt yield
Traditional lending metrics like DSCR and LTV can be manipulated by changing loan terms. A borrower can lower the interest rate or extend the amortization to improve DSCR without changing the underlying property economics. LTV depends on appraised value, which involves subjective judgment.
Debt yield strips out all of that. It uses only two numbers: the property's actual income and the loan amount. No interest rate, no amortization schedule, no appraisal. This makes it a cleaner measure of the lender's risk position.
Minimum debt yield thresholds
Most commercial lenders require a minimum debt yield, though the threshold varies by property type and lender:
| Property Type | Typical Minimum Debt Yield |
|---|---|
| Multifamily (stabilized) | 7-8% |
| Office / Retail | 9-10% |
| Industrial | 8-9% |
| Hotel / Hospitality | 11-13% |
| Construction / Bridge | 10-12% |
CMBS lenders (commercial mortgage-backed securities) typically require 10% minimum debt yield regardless of property type. Balance sheet lenders may be more flexible.
Debt yield vs. DSCR vs. cap rate
These three metrics measure different aspects of the same property:
- Debt yield = NOI / Loan Amount. Measures lender's return on loan balance. Independent of loan terms.
- DSCR = NOI / Annual Debt Service. Measures ability to cover mortgage payments. Affected by interest rate and amortization.
- Cap rate = NOI / Property Value. Measures investor return on total investment. Affected by market valuation.
Same property, three metrics:
NOI: $200,000
Purchase price: $2,500,000
Loan: $1,750,000 (70% LTV)
Debt service: $130,000/year
Debt yield: $200,000 / $1,750,000 = 11.4%
DSCR: $200,000 / $130,000 = 1.54x
Cap rate: $200,000 / $2,500,000 = 8.0%
How debt yield affects loan sizing
When a lender has a 10% minimum debt yield requirement, it effectively caps the loan amount:
Maximum Loan = NOI / Minimum Debt Yield
If NOI = $200,000 and minimum debt yield = 10%, max loan = $200,000 / 0.10 = $2,000,000
Compare this to the LTV constraint: if the property appraises at $2,500,000 and the lender allows 75% LTV, the LTV-based max loan is $1,875,000. The lender uses whichever is more restrictive. In this case, the LTV constraint ($1,875,000) is tighter than the debt yield constraint ($2,000,000), so LTV governs.
In low-cap-rate markets where property values are high relative to income, debt yield often becomes the binding constraint rather than LTV.
Improving your debt yield
There are only two ways to improve debt yield: increase NOI or decrease the loan amount.
- Increase NOI: Raise rents to market, reduce vacancy, cut operating expenses, add income sources (parking, laundry, storage).
- Decrease loan amount: Bring more equity to the deal. This may mean finding equity partners or using less leverage.
Debt yield cannot be improved by negotiating better loan terms (lower rate, longer amortization) because the formula ignores loan terms entirely. This is why lenders like it as a risk metric. For deeper analysis of income properties, see our income approach guide and NOI explanation.
