What do indirect costs contribute to in an intervention budget?

Indirect costs contribute to the overall cost of an intervention by encompassing expenses that are not directly tied to a specific project or activity but are essential for the functioning and support of the intervention as a whole. These may include overhead costs such as utilities, administrative salaries, and other operational expenses that sustain the organization or initiative implementing the intervention.

Understanding indirect costs is crucial in budget management, particularly in fields like healthcare and research, where they can represent a significant portion of total expenses. When preparing a budget for an intervention, it's important to account for these costs to ensure that the financial resources allocated can adequately support not just the direct activities but the infrastructure needed for successful execution.

In contrast, the other options focus on more specific or direct forms of financial categorization that do not encapsulate the broader scope of indirect costs.
