Debt Yield Calculator

Debt Yield Calculation

Debt yield is calculated by dividing annual Net Operating Income (NOI) by the total loan amount: Debt Yield = NOI ÷ Loan Amount. Calculate commercial real estate debt yield in seconds, solve for maximum loan amount, and size proceeds across debt yield, DSCR, and LTV constraints.

Workflow

How it works

Follow the underwriting path lenders use: input the deal, apply constraints, then read the result.

Step 1

Determine underwritten NOI

Input your property's annual Net Operating Income (gross revenues minus operating expenses and vacancy, before debt service). Lenders evaluate this after standard replacement reserve deductions.

Debt Yield Calculation: Formula and Worked Example

Debt yield is net operating income divided by the loan amount, expressed as a percentage. The debt yield ratio — the two terms mean the same thing — is the figure lenders use to gauge how quickly they would recover their money in a default. Lenders prefer it over loan-to-value and debt service coverage because it is independent of the interest rate, the amortization period, and the appraised value. A borrower cannot engineer a better debt yield by stretching amortization or shopping for a higher appraisal — only real income or a smaller loan moves it. The formula also runs in reverse: maximum loan equals NOI divided by the minimum debt yield. A lender requiring a 10% debt yield on a property generating $800,000 of NOI will cap the loan at $8,000,000 regardless of what the appraisal says the building is worth. That single line of arithmetic is why debt yield so often surprises borrowers who sized their deal on LTV alone. Full loan sizing applies all three constraints simultaneously — debt yield, LTV, and DSCR — and the binding constraint is whichever produces the lowest maximum loan. To convert rate and amortization into annual debt service for the DSCR test, you can calculate the loan constant. The lowest of the three tests is the modeled ceiling. Other underwriting requirements, fees and holdbacks can further reduce proceeds. For an in-depth tutorial on how lenders adjust NOI and underwrite reserves, see our guide on how to calculate debt yield.

Read the calculation methodology and limitations.

Debt Yield   = NOI ÷ Loan Amount
Max Loan     = NOI ÷ Minimum Debt Yield
Binding Loan = MIN(Max by DY, Max by LTV, Max by DSCR)
Example

A property with $1,200,000 NOI and a $12,000,000 loan has a debt yield of 1,200,000 ÷ 12,000,000 = 10.0%. Run in reverse at an 8% minimum, the same NOI supports a maximum loan of 1,200,000 ÷ 0.08 = $15,000,000. If that property is worth $16,000,000 at 75% max LTV ($12,000,000) and DSCR caps the loan at $13,500,000, the binding constraint is LTV — the modeled ceiling is $12,000,000, the lowest of the three, before other constraints.

The request meets the assumed 10% target. DSCR, LTV and other requirements still need separate checks.

Quick facts

  • Debt yield is annual property income divided by the loan balance.
  • Changing rate or amortization leaves debt yield unchanged when income and balance stay fixed.
  • A lower assumed debt-yield target increases the loan supported by that test alone.
  • Use the lender's required income definition, including any reserve adjustment, consistently.
  • Passing a calculated target does not establish loan approval or agency eligibility.
