Fixed Overhead Variances

A direct labour variance is the difference between the standard cost of direct labour (expected) and the actual cost. The variance is made up of two other variances:
  • Spending Variance: Difference between what was actually spent on fixed overhead and the total amount that was budgeted.
  • The standard price is the predetermined overhead rate


  • Volume Variance: Difference between the amount of fixed overhead that was applied to production and the total amount that was budgeted.
  • Total Variance: The sum of the spending and volume variance.


PAGE BREAK
What causes Fixed Overhead spending variance
  • Unexpected increase or decrease in a fixed overhead expense during the period. For example an unexpected increase in the insurance premium for the factory.
  • Waste and inefficiencies in the management of fixed overhead costs.
What causes Fixed Overhead volume variance
  • Producing more or less units than originally expected when preparing the budgets.
  • Underestimating or overestimating time required to produce units.

Example: Fixed Overhead Variances

Wize Corporation manufactures a single product and has the following standard costs per unit of finished goods:



The company's master budget indicates that the normal capacity for any given month is 5,000 units, and in the month of August 2020, 4,800 units were actually produced. The budgeted variable and fixed overhead cost are $87,500 and $112,500 respectively. In producing the 4,800 units, the following costs were incurred:


Compute the Fixed Overhead spending, volume and total variances.

Practice: Fixed Overhead Variances

Buono Corporation manufactures fire extinguishers for residual and commercial use. The standard material cost of producing one unit is $30 (3 lbs of material @ $10/lb). The standard labor rate of workers at the company is $15 per hour, and it is expected that each unit will require 1 hour of labor to be produced.

The budgeted overhead cost is $500,000, of which 30% is variable and the rest is fixed. The company's budget is based on producing 10,000 units this year.

At the end of the year, the company had produced 9,300 units and the following costs were incurred:
  • Direct materials (31,000 lbs) $308,450
  • Direct labor (9,100 hours) $141,050
  • Variable overhead: $180,000
  • Fixed overhead: $334,550
