Explanation:

The budget variance can be calculated using either a static budget or a flexible budget. All measures have to be conducted at the end of the accounting period. The static budget is projected at the end of the year and represents changes in the costs -raw materials- business operations over the year. These are only designed for one level of production volume and do not adjust after they have been created.

Flexible budgets are calculated by the beginning of the year and can vary based on the level of production during the year. These are calculated for various volume rates and separate fixed and variable costs.
