Explanation: In simple words, revenue variance refers to the difference between the revenue one expects to earn as per the budget made for a specified period of time and the revenue it actually earned in that time.
Organisations calculate revenue variance to identify the reasons they are not performing well or the qualities they are performing more than expected.
This measure helps organisation in decision making as to whether they should make changes in their process, and if so then wheat changes, or should remain as they are.
