    From my earlier studies and F5 costing chapters, I clearly understood that within an absorption costing approach, fixed cost stay constant as a whole and vary per unit according to the level of output. could anybody please tell me why in this example they stay constant per unit and vary as a whole?, which makes them exactly like variable overheads

      Of course fixed overheads stay fixed in total!!!
      I do not say any different in this lecture.

      However, I am trying to explain in the lecture that when we are using absorption costing for variance analysis it is effectively treating the fixed overheads on a unit basis i.e. as though they are variable.
      Obviously they are not variable and that is why we have a fixed overhead volume variance to ‘correct’ for this.

      (It is actually exactly the same problem as you will have been through in Paper F2 on absorption costing (and in variance analysis – ‘basic’ variance analysis here is revision of F2. Because of what I have written above we had in F2 to be able to adjust for the over/under absorption of fixed overheads.)

      Rent is a fixed expense. Assume that the company is working on a rented building, and the company has to pay the entire rent for the month even if it doesn’t work for the entire month!
      Hope that helps…..

    Can someone please help me with this question below. And if the answer can be supported by an explanation, it would be a great help.

    A company has a fixed overhead volume variance that is $10,000 unfavorable. The most likely cause for this variance is that
    a. the production supervisory salaries were greater than planned.
    b. the production supervisory salaries were less than planned.
    c. more was produced than planned.
    d. less was produced than planned.

    Cheers,
    Ali

      The answer is d

      The reason is that when using absorption costing, when the standard profit is calculated is is effectively assuming that fixed overheads are charged on a unit basis and the amount charged for fixed overheads will be the actual production at fixed cost per unit, which will be less than the budget production at fixed cost per unit.
      It is difficult to explain here without numbers, but the lecture does explain.

      However…..the easy way to remember whether the volume variance is favourable or adverse is to say: if production is more than budget then we have done well – it is good – and the variance is favourable. Vice versa if production is less than budget. That way of thinking always works :-)

      (answers a and b have clearly nothing to do with the volume variance – they will create a fixed overhead expenditure variance)

    Just wondered if Basic Variances (price, labour, volume etc) are relevant for Dec 2013 exam. I have checked the syllabus and I can’t see them. All I can see Budgeting and Standard Costing, Material Mix which includes Yield variances but not the basic variances. Or is this knowledge assumed to have acquired in F2 study and will be tested in F5 exam? I am sorry if I sound silly but I am bit confused and hope someone will help me.

      It is assumed knowledge from Paper F2.

      You will not be set a whole question on basic variances, but they can be part of a question (and were in June 2013 exam).
      Also, knowledge of basic variances is essential to understand planning and operational variances.
