When talking about debts or financial obligations, the term "amount owed" is commonly used. However, there are several synonyms that can be used interchangeably depending on the context. For instance, the term "outstanding balance" is commonly used to describe the unpaid amount on loans or credit cards. "Debt" is another synonym that refers to the total amount owed to creditors. In accounting, the term "accounts payable" is used to describe money that a company owes to its vendors or suppliers. Other possible synonyms include "arrears," "liabilities," and "payables." Ultimately, the choice of synonym will depend on the specific context and the level of formality required.
