Now we will follow the same basic worked example as before, but this time using marginal costing. Again, we will be preparing the budget for the months of January to April inclusive, but we will also have to process some data from before and after these months.
But the monetary values of these inventories will be different because, under marginal costing, the product cost includes variable production costs only.
This book, (1) on the current state of standard costing, focuses on the methodology of Marginal Costing. Marginal Costing (1B) is a type of flexible standard costing that separates fixed costs from proportional costs in relation to the output quantity of the objects.
For this reason, we first need to look at how Marginal Costing is currently integrated into management accounting.
These new rules retain many of the familiar attributes of the FSC, such as determination of profits on a transactional basis, marginal costing
