What is a debt service coverage ratio (DSCR)?

DSCR is a financial metric used by lenders to assess a borrower’s ability to cover their debt obligations with available income. It measures the relationship between a company’s operating income and its debt obligations, indicating its ability to service its debt.

DSCR Formula

DSCR = Net Operating Income / Total Debt Service.

Net Operating Income represents the income generated by a business before interest and taxes, while Total Debt Service includes all principal and interest payments on outstanding debt.

What is a good DSCR ratio?

The DSCR required to qualify for a loan varies depending on the lender, the type of loan and the specific circumstances of the borrower. Generally, lenders look for a DSCR of at least 1.25 to 1.5, indicating that the business’s operating income is sufficient to cover its debt obligations comfortably.

What is a DSCR loan?

A DSCR loan is a type of financing where the lender evaluates the borrower’s ability to service debt using the Debt Service Coverage Ratio (DSCR). Lenders use this ratio to assess the borrower’s financial health and determine their eligibility for the loan.

How to get a DSCR loan?

To qualify for a DSCR loan, borrowers typically need to demonstrate a strong DSCR, sufficient collateral and a solid financial track record. Lenders may also consider factors such as the borrower’s credit history, business plan and, and industry trends when evaluating loan applications.
