Say that a company has a debt of 10 million $US
But from that debt, the company has to pay 2 million $US today. The rest of the debt has to be payed next year and later.
Is there a term for the debt that has to be paid today?
Are you thinking of "due debt"?
Debt due today is an example of a current liability, although that term also includes liabilities due within one year, and is contrasted with long-term liabilities which are those due in more than one year.
