Management Accounting Flashcards
three rationales of management accounting
planning, decision-making, and controlling
define a relevant cost
list the three criterias a cost must qualify to be relevant
a cost that is going to be affect by a particular decision
its for one-off decisions
For a cost to be relevant it has to satisfy three criteria:
- Has to be a cashflow
- Has to be in the future
- There has to be a difference (increment)
Examples:
- an additional cash inflow
- an additional cash outflow
- an existing cash inflow lost
- an existing or potential cash outflow saved or avoided
non-relevant costs
+ examples
a cost will remain unaltered regardless of the decision
- Sunk or past costs
- Fixed overheads
- Committed costs
- you’ve already signed a contract, hence can’t change it
- Depreciation
- because it is not cashflow
opportunity cost
the loss of other alternatives when one alternative is chosen
a special type of relevant cost
avoidable costs
if it can be avoided, it’s a relevant cost
(Costs of an activity or sector of a business which would be avoided if the activity or sector did not exist.)
differential / incremental cost
- The difference in total costs between alternatives
- Useful to highlight the consequences
It’s the difference between the cost of two alternative decisions, or of a change in output levels. The concept is used when there are multiple possible options to pursue, and a choice must be made to select one option and drop the others.
analysing the cost of an item (formula)
a physical quantity measurement x a price measurement
Example
To manufacture Product X, we need 200 hours of labour time at a rate of £4 per hour. Labour cost = £800
(physical quantity is hours)
Variable costs vs. Fixed Costs
Variable costs increase in direct proportion to the increased level of activity.
Fixed costs do not vary whatever the level of activity, in the short-run.
Direct Costs vs. Indirect Costs
-
Direct costs are directly traceable to an activity of the business
- Costs directly related to a product, or a service, or a location
-
Indirect costs are spread over a number of activities of the business
- Costs not directly related to a product, or service, or location and have to be apportioned on a basis
Product Costs vs. Period Costs
Product costs (manufacturing costs) are costs associated with goods or services purchased, or produced, for sale to customers.
- These include direct materials, direct labour, and indirect manufacturing costs such as salaries for timekeepers, supplies of materials for repairs and maintenance
Period costs (non-manufacturing costs) are those costs which are treated as expenses in the period in which they are incurred.
- These costs are not included in the cost of sales (like a temporary external consulting task force)
- Examples: administrative and marketing costs
cost centers
- Something you want to find a cost for.
- A unit of organisation in respect of which a manager is responsible for costs under his or her control
- A location, or a function, or a group of machines
- Must be a homogeneous unit carrying out a single form of activity
profit centers
- Something you want to find out the cost and revenue.
- A unit of organisation in respect of which a manager is responsible for revenue and costs
investment centers
- Where the manager has autonomy on where and how the finance of an activity takes place.
- Should I expand oversees, open a new factory?
- A unit of organisation in respect of which a manager is responsible for capital investment decisions, revenue and costs
prime costs
costs directly traceable to the relevant jobs / each unit of product
(cutting glass for the phone)
aim of (traditional) absorption costing
Trying to attach indirect costs to the product.
- rent
- supervisor’s salary
The manufacturing overheads will be spread across a range of jobs, not directly traceable to each individual job.
Problems arise when we try to allocate the production overheads to the jobs.
absorption costing: allocate
assign a whole item of cost/revenue to a single cost unit, centre, account
Allocating should be the first thing to do, if enough information is available.
absorption costing: apportion
where there isnt enough data to allocate, spread costs over two or more cost units, centres, accounts
absorption costing: absorb
absorb (take onboard) overhead costs into products or services
absorption costing: three steps overview
- allocate/apportion indirect costs/production overheads to the cost centres
- apportion service cost centre to production cost centre
- absorb overhead costs into product
Limitations of Absorption Costing
- Major difficulty in traditional costing is the inclusion of fixed costs (attaching the heating cost to the product)
- Methods used to apportion these costs are arbitrary/subjective
- Different O/H base resulted in different O/H rates, resulted in different departmental costs and product costs
marginal costing aka. variable costing
Marginal costing assigns only the marginal costs (direct costs), costs which vary with the level of production, to the products.
Marginal costing is about decision-making, especially concerning short-term decisions - a lot better than absorption costing.
The main difference between absorption costing and marginal costing approach is the way we treat the Indirect Manufacturing Costs.
For absorption costing, we will apportion and absorb the Indirect Manufacturing Costs into the product to arrive at the Production Costs.
But for Marginal Costing, the Indirect Manufacturing Costs are treated as Period costs, not as part of the Product Costs.
Under marginal costing, the indirect manufacturing costs will be treated as ‘Other Expenses’, and will not be charged to the product to form part of the ‘Cost of good sold / Production Costs’
