The debt service coverage ratio (DSCR), known as "debt coverage ratio" (DCR), is a financial metric used to assess an entity's ability to generate enough cash to cover its debt service obligations. These obligations include interest, principal, and lease payments. The DSCR is calculated by dividing the operating income available for debt service by the total amount of debt service due.

A higher DSCR indicates that an entity has a greater ability to service its debts, making it easier for it to obtain loans. Banks and lenders often use a minimum DSCR ratio as a condition in the covenant, and a breach can sometimes be considered an act of default.

Uses

In corporate finance, DSCR refers to the amount of cash flow available to meet annual interest and principal payments on debt, including sinking fund payments.

Debt service coverage ratio

In personal finance, DSCR refers to a ratio used by bank loan officers in determining debt servicing ability.

In commercial real estate finance, DSCR is the primary measure to determine if a property will be able to sustain its debt based on cash flow. In the late 1990s and early 2000s banks typically required a DSCR of at least 1.2, but more aggressive banks would accept lower ratios, a risky practice that contributed to the Financial crisis of 2007–2010. A DSCR over 1 means that (in theory, as calculated to bank standards and assumptions) the entity generates sufficient cash flow to pay its debt obligations. A DSCR below 1.0 indicates that there is not enough cash flow to cover loan payments. In certain industries where non-recourse project finance is used, a Debt Service Reserve Account is commonly used to ensure that loan repayment can be met even in periods with DSCR<1.0

Calculation

In general, it is calculated by:

where:

To calculate an entity's debt coverage ratio, you first need to determine the entity's net operating income (NOI). NOI is the difference between gross revenue and operating expenses. NOI is meant to reflect the true income of an entity or an operation without or before financing. Thus, not included in operating expenses are financing costs (e.g. interests from loans), personal income tax of owners/investors, capital expenditure and depreciation.

Debt Service are costs and payments related to financing. Interests and lease payments are true costs resulting from taking loans or borrowing assets. Paying down the principal of a loan does not change the net equity/liquidation value of an entity; however, it reduces the cash an entity processes (in exchange of decreasing loan liability or increasing equity in an asset). Thus, by accounting for principal payments, DSCR reflects the cash flow situation of an entity.

For example, if a property has a debt coverage ratio of less than one, the income that property generates is not enough to cover the mortgage payments and the property's operating expenses. A property with a debt coverage ratio of .8 only generates enough income to pay for 80 percent of the yearly debt payments. However, if a property has a debt coverage ratio of more than 1, the property does generate enough income to cover annual debt payments. For example, a property with a debt coverage ratio of 1.5 generates enough income to pay all of the annual debt expenses, all of the operating expenses and actually generates fifty percent more income than is required to pay these bills.

A DSCR of less than 1 would mean a negative cash flow. A DSCR of less than 1, say .95, would mean that there is only enough net operating income to cover 95% of annual debt payments. For example, in the context of personal finance, this would mean that the borrower would have to delve into his or her personal funds every month to keep the project afloat. Generally, lenders frown on a negative cash flow, but some allow it if the borrower has strong outside income.

Typically, most commercial banks require the ratio of to ensure cash flow sufficient to cover loan payments is available on an ongoing basis.

Example

Let's say Mr. Jones is looking at an investment property with a net operating income of and an annual debt service of . The debt coverage ratio for this property would be 1.2 and Mr. Jones would know the property generates 20 percent more than is required to pay the annual mortgage payment.
