What defines a flexible budget?

A flexible budget is defined as a budget that adjusts for changes in the volume of activity. This means that as the level of activity increases or decreases, the budget is adjusted to reflect those changes in costs and revenues. This flexibility allows management to compare actual performance against a more accurate benchmark that takes into account the actual level of activity, rather than a static figure that does not reflect varying conditions.

For example, if a company anticipates a higher sales volume, a flexible budget will consider the variable costs associated with producing and selling those additional units, allowing for a more relevant analysis of performance and operational efficiency. This characteristic of flexibility is crucial in managerial accounting, as it provides a clearer insight into financial performance under different conditions, thus aiding in better decision-making.

In contrast, other types of budgets mentioned do not offer this adaptability. For instance, a budget that remains unchanged regardless of activity levels lacks the responsiveness that a flexible budget provides, and one that only accounts for fixed costs does not include the variable costs that change with production levels. A static budget set at the beginning of the fiscal year fails to account for fluctuations in activity, rendering it less useful for ongoing performance evaluations.
