1 The planning budget is prepared for the planned level of activity. It is static because it is not
adjusted even if the level of activity subsequently changes.
92 A flexible budget can be adjusted to reflect any level of activity—including the actual level of
activity. By contrast, a static planning budget is prepared for a single level of activity and is not
subsequently adjusted.
93 Actual results can differ from the budget for many reasons. Very broadly speaking, the differences
are usually due to a change in the level of activity, changes in prices, and changes in how effectively
resources are managed.
94 As noted in 93 above, a difference between the budget and actual results can be due to many
factors. Most importantly, the level of activity can have a very big impact on costs. From a manager’s
perspective, a variance that is due to a change in activity is very different from a variance that is due to
changes in prices and changes in how effectively resources are managed. A variance of the first kind
requires very different actions from a variance of the second kind. Consequently, these two kinds of
variances should be clearly separated from each other. When the budget is directly compared to the
actual results, these two kinds of variances are lumped together.
95 An activity variance is the difference between a revenue or cost item in the static planning budget
and the same item in the flexible budget. An activity variance is due solely to the difference in the level of
activity assumed in the planning budget and the actual level of activity used in the flexible budget. Caution
should be exercised in interpreting an activity variance. The “favorable” and “unfavorable” labels are
perhaps misleading for activity variances that involve costs. A “favorable” activity variance for a cost
occurs because the cost has some variable component and the actual level of activity is less than the
planned level of activity. An “unfavorable” activity variance for a cost occurs because the cost has some
variable component and the actual level of activity is greater than the planned level of activity.
96 A revenue variance is the difference between how much the revenue should have been, given the
actual level of activity, and the actual revenue for the period. A revenue variance is easy to interpret. A
favorable revenue variance occurs because the revenue is greater than expected for the actual level of
activity. An unfavora
