Total debt is short-term-debt plus long-term-debt, and most analysts add finance and operating lease obligations, because a lease commits the company to fixed payments exactly as a loan does. Trade payables are not debt.
Rating agencies and lenders work from gross debt because cash can be spent, while debt cannot be wished away. Equity investors prefer net-debt. Both views are defensible; state which one you are using.
Example: Northwind Tools has $60M short-term plus $430M long-term plus $130M of lease obligations, so total debt is $620M against $195M of ebitda, a gross ratio of 3.2 times.
