Flexible Budget vs Static Budget: Why Do Volume Differences Matter?
A static budget stays at planned activity; a flexible budget recalculates expectations for actual activity.
Static budget
The static budget is built for planned volume and does not change when actual activity differs.
Flexible budget
The flexible budget adjusts revenues and variable costs to actual activity while preserving the underlying budget assumptions.
Why compare both
Comparing actual results only with a static budget mixes operating performance with volume effects.
Exam strategy
Use the flexible budget to evaluate performance at actual activity and the static-versus-flexible difference to analyze volume.
The takeaway
Static budgets preserve planned volume; flexible budgets restate expectations at actual activity so performance can be evaluated more fairly.
