Debt yield formula and denominator consistency
Debt yield divides annual NOI by the entered loan balance and multiplies by 100. Keep NOI before debt service, and label the balance date: an original loan commitment and today’s outstanding principal can produce different percentages for the same property income. This model uses the balance you enter.
DSCR instead divides NOI by annual debt service, while the loan constant compares debt service with loan balance. Changing interest or amortization can affect those two ratios without changing debt yield if NOI and principal stay fixed. None of the results establishes a universal approval threshold or lender decision.
What debt yield measures in real estate
Debt yield expresses annual property NOI as a percentage of the outstanding or proposed loan balance. It compares income with debt principal without using property value, interest rate, or amortization. That makes it a different view from both LTV and DSCR.
The ratio is often used in commercial real estate loan analysis as one of several sizing and risk measures. EstateCalc does not apply a universal target or classify the result. Requirements vary with lender, market conditions, property type, income stability, and the rest of the credit structure.
Debt yield formula for commercial real estate
Divide annual NOI by the loan balance and multiply by 100. Use NOI and principal from the same scenario: a stabilized numerator paired with a current balance answers a different question from trailing NOI paired with a proposed acquisition loan. Label the basis before comparing results.
Debt yield is not the interest yield earned by a lender and is not the borrower’s return. It is a property-income-to-debt ratio. Interest rate, points, amortization, and term affect payments and loan economics, but they do not appear directly in this formula.
Debt yield vs. DSCR and loan constant
DSCR divides NOI by annual debt service, so a rate or amortization change can move DSCR even when NOI and loan balance stay constant. Loan constant divides annual debt service by loan balance. Debt yield can also be viewed as DSCR multiplied by loan constant when every input uses the same period and debt definition.
Showing the three outputs together makes the drivers visible. If debt yield is unchanged but DSCR moves, the payment schedule changed. If both move, NOI or loan balance also changed. This is more informative than treating one ratio as a replacement for the others.
Choosing the NOI and loan balance inputs
NOI should reflect effective gross income after vacancy and collection loss, less recurring operating expenses, before debt service and investor income tax. A lender may stabilize rent, vacancy, management fees, taxes, insurance, and reserves. Use its definition when reproducing underwriting, and preserve your own case separately.
For an acquisition, the proposed funded principal is usually the relevant denominator. For ongoing monitoring, use the outstanding balance at the measurement date. Do not substitute total project cost or property value; those belong in LTC and LTV calculations.
A worked debt yield calculation
With $40,000 of annual NOI, a $350,000 loan balance, and $24,000 of annual debt service, debt yield is about 11.43%, loan constant is about 6.86%, and DSCR is about 1.67x. Each ratio uses the same annual income and debt scenario, while the denominators remain distinct.
If annual NOI falls to $32,000 and principal and payments stay unchanged, debt yield becomes about 9.14% and DSCR becomes about 1.33x. Loan constant stays about 6.86% because it contains no NOI. These arithmetic scenarios illustrate the formulas; they do not set a lending threshold or classify the result.
Stress-testing debt yield and refinance risk
Test NOI reductions from vacancy, lease rollover, expense growth, or loss of ancillary income. Then test alternative loan balances. Because debt yield ignores the interest rate, pair it with DSCR scenarios using current and stressed payments to see both principal leverage and payment sensitivity.
The calculation does not forecast refinance proceeds or market value. A future lender may use different income, value, leverage, and coverage requirements. Treat the result as one transparent input to a broader underwriting review.

Debt Yield Calculator FAQ
Can financing terms change DSCR without changing debt yield?
Yes. Debt yield depends on NOI and loan balance, whereas DSCR also depends on annual debt payments. Compare all inputs over the same period and balance date.
What is the debt yield formula?
Debt yield equals annual net operating income divided by the outstanding or proposed loan balance, multiplied by 100%.
Is debt yield the same as interest rate?
No. Debt yield is property NOI divided by loan principal. It does not measure the lender’s contractual interest return and does not directly use rate or amortization.
How is debt yield different from DSCR?
Debt yield uses loan balance as the denominator. DSCR uses annual debt service, so DSCR changes when the payment schedule changes even if NOI and principal do not.
Does property value affect debt yield?
Property value is not in the formula. Value affects LTV and may influence the lender’s overall decision, but debt yield uses only NOI and loan principal.
Which loan balance should I enter?
Use proposed funded principal for a new-loan scenario or outstanding principal at the measurement date for portfolio monitoring. Match it to the NOI period and purpose being analyzed.
