Cash flow available for debt service

Cash flow available for debt service is the earnings figure a lender sets against principal and interest payments. BDC divides EBITDA by principal and interest for the debt service coverage ratio, and gives a separate rule of thumb built on net income plus depreciation.

This is the top half of a coverage test: the cash a business earns that can go toward loan payments. The debt service coverage ratio divides it by the payments due. In a purchase, ask which of the target’s financial statements the figure is built from and how it is defined, because a different definition gives a different result.

Definitions in BDC’s guidance

BDC’s glossary calculates the debt service coverage ratio by dividing EBITDA by principal and interest. A BDC article on how banks assess a business gives a different rule of thumb: borrowing capacity is guided by net income plus depreciation, less the annual repayments of existing term debt. The same article says any profit a business earns is available to cover new debt service, and describes the debt-service coverage ratio using adjusted EBITDA, less current income taxes, distributions paid and unfunded capital expenditures.

What to ask

  • Which definition the lender is using, in writing.
  • Whether the lender adjusts the seller’s earnings before using them.
  • Whether the owner’s own pay is deducted, since a new owner may need to be paid.
  • Whether payments on existing debt are subtracted.
