Legal Definition
Interest expense refers to the costs incurred by a legal entity for borrowing money, typically expressed as the cost of financing or the expense associated with debt obligations. In a legal context, it represents the direct costs of borrowing capital, such as interest paid on loans or debt instruments.
Plain-English Translation
Imagine you need to borrow money from a bank. The 'interest expense' is the extra cost you pay for that loan. It’s the fee the company pays just for having borrowed money instead of paying the full amount right away.
