    Last month a manufacturing company’s profit was $2,000, calculated under the absorption costing principles. If marginal costing principles had been used a loss of $3,000 would have occurred. The company’s fixed production cost is $2 per unit. Sales last month were 10,000 units.

    What was last month’s production unit?

    Answer 12,500 units

    Sir John, I don’t understand how there is $3000 loss under marginal costing Shouldn’t it be a profit since production units are higher than sales units.

    Can you please clarify

    Thank you

    As I explain in my free lectures, the only difference ever between the absorption and marginal profits is the change in inventory multiplied by the fixed production cost per unit.

    If inventory increases then absorption gives the higher profit. If inventory decreases then marginal gives the higher profit.

    Here, the change in inventory is 5,000/2 = 2,500 units.
    The absorption profit is higher and therefore the inventory has increased.

    Therefore they produced 2,500 more units than they sold.

    Again, this is all explained in detail in my free lectures 🙂

    Sir John, I re-watched the lecturers, just let me know if my understanding is correct

    Question 1

    Opening inventory 16,500
    Closing inventory 18,000
    Change in inventory 1500

    Fixed production overhead rate is $10

    Profit using absorption costing is $40,000

    What is profit using marginal costing

    1500 x $10 = $15,000
    $40,000 – $15,000 = $25000

    Question 2

    Opening inventory 18,000
    Closing inventory 16,500
    Change in inventory 1500

    Fixed production overhead rate is $10

    Profit using absorption costing is $40,000

    What is profit using marginal costing

    1500 x $10 = $15,000
    $40,000 + $15,000 = $55,000

    Sir can you clarify this one too

    Question 1

    Production 18,000
    Sales 16,500
    Change in inventory 1500

    Fixed production overhead rate is $10

    Profit using absorption costing is $40,000

    What is profit using marginal costing

    1500 x $10 = $15,000
    $40,000 – $15,000 = $25,000

    Question 2

    Production 16,500
    Sales 18,000
    Change in inventory 1500

    Fixed production overhead rate is $10

    Profit using absorption costing is $40,000

    What is profit using marginal costing

    1500 x $10 = $15,000
    $40,000 +$15,000 = $55,000

    They are the same questions – you should be able to check yourself 🙂
