Flexible Budgets and Performance Analysis
Solutions to Questions
9-1 A planning budget is prepared before
the period begins and is valid for only the
planned level of activity. It is sometimes referred
to as a static planning budget because it is not
adjusted even if the level of activity
subsequently changes.
9-3 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.
9-4 As noted 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
assumed in the planning 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
9-6 If the actual level of activity is greater
than the planned level of activity, the activity
variances for variables expenses will be
unfavorable.
9-7 A revenue variance is the difference
between the actual revenue for the period and
how much the revenue should have been, given
the actual level of activity. 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
unfavorable revenue variance occurs because
the revenue is less than expected for the actual
level of activity.
