In economics, barriers to exit are obstacles in the path of a firm that wants to leave a given market or industrial sector. These obstacles often have associated costs, prohibiting the firm from leaving the market. If the barriers of exit are significant, a firm may be forced to continue competing in a market. This forced stay in the market occurs when the costs of leaving a market are higher than costs incurred by continuing in the market. Sometimes, when firms operate at low profit or at loss, they still choose to compete with others. Major factors of this decision making is high barriers to exit.

Direct costs of exit and indirect opportunity costs of exit are covered in this definition. In 2021, Will Kenton gives a very clear definition which states, "Barriers to exit are obstacles or impediments that prevent a company from exiting a market in which it is considering cessation of operations, or from which it wishes to separate." Kenton mentions how "Barriers to exit can be compared with barriers to entry." All of the above definitions describe barriers to exit as obstacles that may force a firm to continue operating in a market or a consumer to continue using a firm.
