48 Compute and Evaluate Overhead Variances

Recontact that the conventional expense of a product consists of not just products and also labor however also variable and also solved overhead. It is likely that the quantities established for conventional overhead expenses will certainly differ from what actually occurs. This will bring about overhead variances.

Determination and Evaluation of Overhead Variance

In a traditional expense system, overhead is applied to the items based upon a typical overhead price. This is equivalent to the prefigured out overhead rate supplied previously. The standard overhead rate is calculated by splitting budgeted overhead at a offered level of manufacturing (known as normal capacity) by the level of activity compelled for that certain level of manufacturing.


Units of output at 100% is 1,000 candy boxes (units). The conventional overhead price is the full budgeted overhead of ?10,000 split by the level of task (direct labor hours) of 2,000 hrs. Notice that fixed overhead remains consistent at each of the production levels, however variable overhead transforms based on unit output. If Connie’s Candy just produced at 90% capacity, for example, they should mean total overhead to be ?9,600 and a typical overhead price of ?5.33 (rounded). If Connie’s Candy developed 2,200 systems, they must intend full overhead to be ?10,400 and a standard overhead rate of ?4.73 (rounded). In enhancement to the full conventional overhead price, Connie’s Candy will desire to know the variable overhead rates at each task level.

Using the flexible budobtain, we deserve to recognize the conventional variable expense per unit at each level of manufacturing by taking the total intended variable overhead split by the level of task, which deserve to still be direct labor hrs or machine hrs.


Factoring out actual hours functioned, we can recompose the formula as


Connie’s Candy also had actually this actual output information:


Connie’s Candy likewise had this actual output information:


Factoring out traditional overhead rate, the formula can be composed as


Connie’s Candy likewise had actually the following actual output information:


Connie’s Candy also had the following actual output information:


For example, Connie’s Candy Company kind of had actually the adhering to information easily accessible in the flexible budget:


The variable overhead price variance is calculated as (1,800 × ?1.94) – (1,800 × ?2.00) = –?108, or ?108 (favorable). The variable overhead efficiency variance is calculated as (1,800 × ?2.00) – (2,000 × ?2.00) = –?400, or ?400 (favorable).

The full variable overhead cost variance is computed as:

( extTotal Variable Overhead Cost Variance=left(–?108 ight)+left(–?400 ight)=–?508phantom ule0.2em0ex extorphantom ule0.2em0ex?508phantom ule0.2em0exleft( extFavorable ight))

In this instance, 2 elements are contributing to the favorable outcome. Connie’s Candy provided fewer direct labor hours and also less variable overhead to develop 1,000 candy boxes (units).

The same calculation is presented as follows in diagram format.


What is the typical variable overhead price at 90%, 100%, and also 110% capacity levels?


90% = ?315,000/14,000 = ?22.50, 100% = ?346,000/16,000 = ?21.63 (rounded), 110% = ?378,000/18,000 = ?21.00.

The XYZ Firm is bidding on a contract for a new aircraft for the military. As the administration team is going over the bid, they pertained to the conclusion it is as well high on a per-aircraft basis, yet they cannot uncover any type of expenses they feel deserve to be reduced. The indevelopment from the armed forces states they will purchase in between 50 and 100 planes, yet will more most likely purchase 50 planes rather than 100 planes. XYZ’s bid is based upon 50 planes. The controller says that they base their bid on 100 planes. This would spread the resolved expenses over more planes and mitigate the bid price. The reduced bid price will boost significantly the opportunities of XYZ winning the bid. Should XYZ Firm save the bid at 50 planes or rise its bid to 100 planes? What are the pros and cons to maintaining the bid at 50 or enhancing to 100 planes?

Key Concepts and Summary

There are 2 sets of overhead variances: variable and solved.The variable variances are led to by the overhead application price and the activity level versus which the rate was used.The variable overhead price variance is the distinction in between the actual variable manufacturing overhead and also the variable overhead that was supposed given the number of hrs worked.The variable overhead efficiency variance is thrust by the difference between the actual hrs worked and also the traditional hours supposed for the devices developed.Tbelow are two addressed overhead variances. One is resulted in by spending as well much or as well little bit on addressed overhead. The other is led to by actual production being over or below the supposed production level.
