Debt Service

What Is Debt Service?

Debt service is the cash needed to meet the scheduled payments on a loan or other debt during a set period, usually a year. It includes two parts: the interest charged on the balance and the principal, which is the portion that reduces the amount owed. Companies, governments, and households all have debt service, and it is one of the most closely watched measures of whether a borrower can keep up with its obligations.

How It Works

Each scheduled payment on a loan is split between interest and principal. Early in a loan, a larger share of each payment goes to interest. Later, more goes to principal. Adding up all payments due over a year gives the annual debt service. Some borrowers also make irregular payments, such as balloon payments or sinking fund contributions, which are included in the total when they fall due.

Analysts often compare debt service with the cash a borrower generates. A common version is the debt service coverage ratio, which divides operating income by debt service. A ratio above 1.0 means earnings cover the payments, while a ratio below 1.0 means the borrower must find other funds or borrow more.

Why It Matters to Investors

Debt service shows how much of a company's cash flow is committed to lenders before shareholders receive anything. A company with high debt service has less room to invest, pay dividends, or absorb a downturn in sales. Lenders use the same figure when deciding whether to extend credit, and bond investors watch it to judge the risk of default.

Debt service is not the same as total debt. A company can have a large balance owed but low annual payments if the loans have long terms or low interest rates. Changes in rates can also shift the figure, especially for debt that resets periodically. Investors usually read debt service alongside the level of leverage and the borrower's cash flow to get a complete picture.
