According to the CRISC Review Manual1, cost of controls is the amount of money or resources that an organization is willing to spend to implement and maintain risk responses. Cost of controls is one of the factors that influences the risk appetite of an organization, as it reflects the trade-off between the benefits and costs of risk responses. Cost of controls helps to determine the optimal level of risk that an organization can accept in pursuit of its objectives, and to align the risk responses with the organization's strategy, goals, and culture.
