What factors causes Budget Variance?
There are 7 variances associated with a budget ( which are generally calculated for controlling purposes) 1- Material Price variance 2- Material Quantity variance 3- Labor rate variance 4- Labor efficiency variance 5- Spending variance 6- Efficiency variance 7- Capacity variance
What is variance?
In most production management systems, a "Planned" quantity and material cost is calculated based on the associated Bill of Materials (BOM) and Operatons being performed (Route) creating labor and overhead related costs. The "Actual" quantities, material costs, and labor/overhead costs are issued to a Work in Process (WIP) account and the quantities/values of the produced items are recieved from the WIP account. A variance usually occurs when there is a difference between the issued material cost plus labor and overhead and the recieved material cost of the produced item. The reasons for these variances can be differences in planned vs actual quantities, differences in system or planned cost of materials, labor, or overhead vs actual cost, or any other potential reason for an unplanned difference.
When a coin is tossed four time then mean and variance of the number of the head?
Mean = 2. Variance = 1.
Fixed-overhead budget variance?
Fixed overhead budgeted variance is the difference between estimated budgeted cost and actual fixed overhead cost of production.
Is variance based on deviations from the mean?
Variance is the squared deviation from the mean. (X bar - X data)^2
