    Hello dear john Moffat sir

    Please guide me on this question sir on calculating the variable cost per unit
    It’s a question from a mock paper

    And I have no idea how to solve this

    This year the output is 6000 units and the overhead cost is $32000.
    Three years ago the output was 3000 units and the overhead cost was $9800

    The price index was 132 three years ago and and 164 this year .

    Using the high low technique . What is the variable cost per unit to the nearest $0.01 expressed in current years prices ?

    Calculate what the current costs would be of the 3,000 units produced three years ago (in the way explained in my free lectures on index number).

    Then use the normal high low technique using the current costs.

    Have you watched the lectures on index numbers and on high-low calculations?

    OK. Well use the index numbers to get the cost of the 3,000 units at current prices. Tell me what you get and then we will take it from there 🙂

    164 /132 x 3000 =3727.27 units

    Is this correct sir

    No it is not correct.

    It is the cost that would be higher as per the index numbers, not the number of units.

    At current prices the cost for 3,000 units would be 164/132 x $9,800 = $12,176

    So now you can use the normal high-low method on costs of:

    For 6,000 units: $32,000
    For 3,000 units: $12,176

    in order to arrive at the variable cost per unit at current prices.

    Sir so the variable cost per unit expressed in current years price is

    32000-12176/6000-3000= $6.608 per unit

    Am I correct

    Secondly
    If the question had asked the variable cost per unit expressed in the 3 years ago’s price then

    164/132 x 32000= 39758

    So for
    6000 units : 39758
    3000 units : 9800

    And v/c expressed in the 3 years ago’s price will be

    39758-9800/6000-3000
    = 9.986 per unit

    Am I correct sir
    Thank you

    Sir I hope 9.986 is correct

    The $6.608 is correct.

    $9.986 is certainly not correct. How could it be correct given that cost 3 years ago were lower than they are now?

    The variable cost expressed in prices 3 years ago is 132/164 x $6.608.
