Definition
DSCR is a critical underwriting metric in commercial real estate lending that measures a property's ability to pay its debt obligations from operating income. It is calculated by dividing the property's net operating income (NOI) by its annual debt service (total principal and interest payments). A DSCR of 1.0x means the property generates exactly enough income to cover its debt — breakeven. A DSCR below 1.0x means the property is not generating enough income to service its debt, which signals distress. Most conventional lenders require a minimum DSCR of 1.20x to 1.35x, meaning the property must generate 20-35% more income than needed to cover debt payments. This cushion protects the lender against income fluctuations, vacancy, or unexpected expenses. Bridge lenders may accept lower DSCRs for transitional properties with a clear path to income growth.
How It Works
Formula
DSCR = Net Operating Income (NOI) / Annual Debt Service
The lender calculates DSCR during underwriting to determine whether the property's income can support the requested loan amount. If DSCR is too low, the lender may reduce the loan amount (lowering LTV) to bring DSCR within their threshold. Alternatively, the borrower may need to demonstrate a plan to increase NOI through rent increases, occupancy improvements, or expense reductions.
Example
A multifamily property generates $600,000 in NOI. The annual debt service on the first mortgage is $450,000. DSCR = $600,000 / $450,000 = 1.33x. This meets most lender requirements. If the same property had $520,000 in debt service, DSCR would drop to 1.15x, which may be below the lender's minimum threshold and require a reduction in loan proceeds.
Why It Matters
DSCR is often the binding constraint in loan sizing — even if LTV allows a larger loan, the lender will reduce proceeds if DSCR falls below their minimum. Understanding DSCR helps sponsors evaluate how much debt a property can support and whether the business plan generates sufficient income to meet lender requirements. A strong DSCR also provides a cushion against vacancy or market downturns.

Frequently Asked Questions
What is the minimum DSCR for a commercial loan?
Most conventional lenders require a minimum DSCR of 1.20x to 1.35x. Bridge lenders may accept lower ratios — sometimes below 1.0x — for transitional properties with a clear value-add business plan.
How do you improve DSCR?
DSCR can be improved by increasing NOI (raising rents, reducing vacancy, cutting expenses) or by reducing debt service (paying down principal, refinancing at a lower rate, or extending the loan term).
Is DSCR or LTV more important?
Both are critical. LTV measures the equity cushion protecting the lender, while DSCR measures the property's ability to service debt from income. Lenders typically use both metrics together, and the loan is sized to the more conservative constraint.
