THE SHORT ANSWER
Debt yield is annual net operating income divided by loan principal, expressed as a percentage. It compares the property's income with the amount lent without directly using the interest rate, amortization schedule, or appraised value. It is a lending-risk measure, not the borrower's investment return.

Calculate debt yield
Debt yield = annual NOI ÷ loan amount × 100. Use a clearly identified loan balance and income period. If there are multiple debt layers, say whether the calculation refers to the senior loan or combined borrowing.
For a hypothetical property with $150,000 NOI and a $1,500,000 loan, debt yield is 10%. With the same income and a $1,800,000 loan, it is about 8.33%. The lower figure reflects more debt supported by the same income.
What makes debt yield different
DSCR changes when required payments change. LTV changes when the value assumption changes. Debt yield instead ties income directly to principal. This can make it a useful cross-check when low payments or an optimistic appraisal make other loan ratios look comfortable.
That independence has limits. Debt yield does not tell you the current monthly payment, the cost of replacing a tenant, or the amount of a balloon balance at maturity. The full loan structure still needs analysis.
| Metric | Main comparison |
|---|---|
| Debt yield | NOI versus loan principal |
| DSCR | Income available for debt versus scheduled payments |
| LTV | Loan principal versus property value |
Use it to understand loan sizing
Rearrange the formula as loan amount = NOI ÷ required debt yield. If a hypothetical lender uses a 10% minimum and accepts $150,000 NOI, that constraint suggests $1,500,000. This is an example of the arithmetic, not an available loan quote.
Another constraint may allow less borrowing. A DSCR requirement, LTV limit, borrower liquidity requirement, or property issue can change the result. A maximum derived from one ratio is not a financing commitment.
Check the income before trusting the percentage
A debt-yield calculation is only as credible as its NOI. Compare historical collections, operating expenses, and lender adjustments. If projected rent increases create the entire margin, show what the ratio looks like before those increases.
Debt yields vary across risk profiles and lender programs. Use a specific lender's documented criteria when analyzing an actual proposed loan, and stress the income input to understand what deterioration would change.
Common questions
Is a higher debt yield always desirable?
It means more NOI per dollar of debt when inputs are comparable. It does not establish that the property is a suitable investment or that its price is reasonable.
Does a lower interest rate improve debt yield?
Not directly. If NOI and principal stay constant, debt yield stays constant. Lower payments can improve DSCR instead.
