Closing inventory in marginal costing is valued at the total variable production cost. In absorption cost it is valued at the total production cost including fixed overheads of production.
(I trust you have watched the full F2 lectures where we go through the syllabus in detail. These revision lectures are just meant to be quick revision of the main points.)
This too : A company uses standard absorption costing. Its fixed overhead absorption rate is $8 per machine hour and each unit of production should take 3 machine hours. Last year there was an opening inventory of finished goods of 4000 units. They produced 30,000 units and sold 25,000 units. The actual profit last year was $526K.
What profit would have been earned under a standard marginal costing system? (the answer is $406K)
my workings are : 4K + 30K – 25K = 9K x $8 = $27,000. $526,000 – $27,000 = $499K. I do not know where did i go wrong.
Sir, how do you work this out? A company uses standard absorption costing. Its fixed overhead absorption rate is $8 per machine hour and each unit of production should take 3 machine hours. Last year there was an opening inventory of finished goods of 4000 units. They produced 30,000 units and sold 25,000 units. 90,000 machine hours were used for production, and the total fixed overheads were $700,000. What was the amount of the over or under absorption of fixed overheads?
Please ask questions like this in the F2 Ask the Tutor Forum – not as comments on lectures.
As you will know from the lectures, the over or under absorption is the difference between the actual fixed overheads and the amount absorbed (i,e, actual hours x standard cost per hour).
The amount absorbed is 90,000 hours x $8 per hour = $720,000. The actual overheads were $700,000.
Yes it has. It is the change in inventory that is relevant. If they produce more than they sell, the inventory will increase. If they sell more than the produce, then inventory will decrease.

Thank you soo much its helping a lot and this is the best source i have found for my revision thank you 🙂
sir can you please tell me that when inventory level decreases marginal gives a higher profit but will the valuation of inventory also give a higher value then absorption costing?
@faaezam, The value of inventory is lower with marginal costing than with absorption costing (because the absorption cost includes fixed overheads whereas the marginal cost does not)
These revision are much more helpful than attending classes… No disturbance, i can rewind and replay in case i didn’t understand.. Zat’s perfect… Very clear explanation, covering details of all chapters!! Thanks a lot!!

Dear Sir/Madam
Please assist , how to calculate the “Closing Stock” using marginal Costing/Variable Costing and Absorption costing
John Moffat says
Have you watched our free lectures?
Closing inventory in marginal costing is valued at the total variable production cost. In absorption cost it is valued at the total production cost including fixed overheads of production.

The only difference between marginal and absorption costing profits is the fixed overheads in opening and closing inventory.
Here, the inventory increases by 5000 units. The fixed overheads per unit are 3 x $8 = $24.
So the profits will be different by 5000 x $24 = $120,000.
Because inventory is increasing, absorption profit will be higher than marginal profit, so the marginal profit is 526,000 – 120,000 = $406,000
Erica says
So here, we totally don’t look at opening inventory of finished goods 4000 units?
John Moffat says
You are only interested in the change in the inventory.
Erica says

(answer is 20,000 over-absorbed)

Erica says
So there’s nothing gotta to do with the opening inventory, production and closing?
John Moffat says
Yes it has. It is the change in inventory that is relevant.
If they produce more than they sell, the inventory will increase. If they sell more than the produce, then inventory will decrease.
