The Debt-Service Coverage Ratio (DSCR) is a key metric used by lenders and credit analysts to determine the ability of a borrower to repay its debt. The DSCR measures how easily a company can cover its interest payments with operating profits. It is calculated by dividing operating income by total interest payments.A high DSCR indicates that the company has more than enough cash flow to cover its debt obligations, while a low DSCR suggests that the company may not be able to meet its obligations in the future. Lenders will usually require borrowers with low DSCRs to undergo additional scrutiny, such as increased loan terms or higher interest rates.The debt-service coverage ratio is also used in personal finance and government budgeting. In personal finance, it can be used to measure an individual's ability to repay their debts. In government budgeting, it can be used to measure whether a country has enough revenue coming in each year to service its debts.
