  • Normal Cost of Normal Output per unit

  • Actual output (450 × 35.2778) is valued at NCNO/U

Detailed Working

  • Primary Material is output of Process I introduced into the process.
  • The Secondary material introduced into the process does not result in an increase in the number of units of material.
  • Normal Loss Units

    The Quantity of Loss to be considered as normal has to be ascertained based on the problem data.
    NLU = 10% of input
    = IP × 10%
    = 500 units × 10%
    = 50 units
  • Normal Output Units

    The quantity of output that should be obtained if the production is carried out under normal circumstances with all losses as normal.
    NOU = IP − NLU
    = 500 units − 50 units
    = 450 units
  • Actual Output Units

    The Output that is actually obtained in the process.

    Where there are no other factors affecting production and resulting in other losses or gains, we assume it to be equal to Normal Output.

    AOU = NOU
    = 450 units
  • Total Cost

    The total cost that is incurred in relation to the process.
    TC = 9,550 + 2,600 + 2,250 + 1,575
    = 15,975

    Known from the debits made to the process account.

  • Normal Loss Realisable Rate Per unit

    The rate at which the normal loss units can be sold.

    NLRR/U = 2/unit

  • Normal Loss Realisation

    The total value of normal loss units valued at their realisable rate per unit.
    NLR = NLU × NLRR/U
    = 50 units × 2/unit
    = 100
  • Normal Cost

    The cost that should have been incurred for the normal output under standard operational conditions. It is given by the total cost set off with any value realisation from normal loss.
    NC = TC − NLR
    = 15,975 − 100
    = 15,875
  • Normal Cost of Normal Output per unit

    The Cost per unit at which the output from the process would be obtained under normal circumstances.
    NCNO/U =
    NC
    NO
    = 15,875450 units
    = 35.2778/unit ( 63518/unit )

    If not too complex, use the fractional value in calculations to minimise the need to approximate values. Otherwise, the more the digits after the decimal we consider the lesser the need for approximation.

    This is the most important value that we derive which would be useful in the valuation of all outputs and losses in processes.

  • Value of Actual Output

    The normal value of the output actually achieved obtained by valuing actual output units at normal cost of normal production per unit.
    VAO = AOU × NCNO/U
    = 450 units × 35.2778/unit (or) 450 units × 63518/unit
    = 15,875

    In the absence of abnormal losses or gains, the value of actual output would be equal to the normal cost.

    VAO = NC
    = 15,875
    This relation may be used for adjusting approximation error.

    Since here VAO = NC, no adjustment is needed.

    Principle for valuation of output

    Normal Loss is valued at market price (net realisable value) and all others are valued at cost

    Actual Output, Abnormal Loss, Abnormal Gain etc., are all valued at the Normal Cost of Normal output per unit as we will learn later on.

Illustration (Problem2)

From the following information relating to an intermediary process, prepare the process account and any other related accounts.

Output of 800 units valued at 84,000 from Process B, the previous process has been input into the process. Additionally expenses on material 42,000, labour 23,000 and overhead 54,000 have been incurred.

The nature of the process is such that there would be a loss of 2% of input normally. Such loss is capable of being disposed off @ 840 per unit normally. On account of a defect in the current batch, an additional expenditure of 4/unit had to be incurred to make the normal loss units saleable. 10 units have been sold @850/unit.

Detailed Working

  • Primary Material is output of Process B introduced into the process.
  • The Secondary material introduced into the process does not result in an increase in the number of units of material.
  • Normal Loss Units

    The Quantity of Loss to be considered as normal has to be ascertained based on the problem data.
    NLU = 2% of input
    = IP × 2%
    = 800 units × 2%
    = 16 units
  • Normal Output Units

    The quantity of output that should be obtained if the production is carried out under normal circumstances with all losses as normal.
    NOU = IP − NLU
    = 800 units − 16 units
    = 784 units
  • Actual Output Units

    The Output that is actually obtained in the process.

    Where there are no other factors affecting production and resulting in other losses or gains, we assume it to be equal to Normal Output.

    AOU = NOU
    = 784 units
  • Total Cost

    The total cost that is incurred in relation to the process.
    TC = 84,000 + 42,000 + 23,000 + 54,000
    = 2,03,000

    Known from the debits made to the process account.

  • Normal Loss Realisable Rate Per unit

    The rate at which the normal loss units can be sold.

    NLRR/U = 840/unit

  • Normal Loss Realisation

    The total value of normal loss units valued at their realisable rate per unit.
    NLR = NLU × NLRR/U
    = 16 units × 840/unit
    = 13,440
  • Normal Cost

    The cost that should have been incurred for the normal output under standard operational conditions. It is given by the total cost set off with any value realisation from normal loss.
    NC = TC − NLR
    = 2,03,000 − 13,440
    = 1,89,560
  • Normal Cost of Normal Output per unit

    The Cost per unit at which the output from the process would be obtained under normal circumstances.
    NCNO/U =
    NC
    NO
    = 1,89,560784 units
    = 241.7857/unit

    The more the digits after the decimal we consider the lesser the need for approximation.

  • Value of Actual Output

    VAO = AOU × NCNO/U
    = 784 units × 241.7857/unit
    = 1,89,560

    In the absence of abnormal losses or gains, the value of actual output would be equal to the normal cost.

    VAO = NC
    = 1,89,560
    This relation may be used for adjusting approximation error.

    Since here VAO = NC, no adjustment is needed.

Units left in stock

= Normal Loss units − Units sold
= 16 units − 10 units
= 6 units

Total value of units sold

= Units sold × Value/unit
= 10 units × 844/unit
= 8,440

Total value of units left in stock

= Units in stock × Value/unit
= 6 units × 844/unit
= 5,064

Sale value

= Units sold × Selling Price/unit
= 10 units × 850/unit
= 8,500

Profit on sale

= Sale Value − cost value
= 8,500 − 8,440

Assumption

The organisation maintains an Integrated Accounting system. Thus regular accounts like Cash a/c and Profit and Loss a/c are used in recording transactions.

Note

The same normal loss account may be used for all the processes. If the organisation intends to maintain information relating to the normal loss arising on each process distinctly, it will create a distinct Normal Loss account for each process, in which case the account head would also include additional words to differentiate one account from the other, say like Process C Normal Loss a/c.
