Cost Accounting and Management Accounting Are Terms Which Are Often Used Interchangeably.
It is not correct to do so. Cost accounting is a part of management accounting.
Cost accounting is mainly concerned with:
Preparing statements (e.g., budgets, costing)
Cost data collection
Applying costs to inventory, products and services
Therefore, management accounting goes beyond cost accounting.
In general, cost accounting information is unsuitable for decision-making.
Cost Classification
Cost accounting is used for:
Preparing statements (e.g., budgets, costing)
Cost data collection
Applying costs to inventory, products and services

Direct Cost vs Indirect Cost
Direct cost is the cost incurred by the organization while performing their core business activity and can be attributed directly in the production cost like raw material cost, wages paid to factory staff etc., whereas Indirect cost is the cost that cannot be directly attributed to the production as these costs are incurred in general and can be fixed or variable in nature like the office expenses, salary paid to administration, etc.
Production Costs
- are costs identified with goods produced for resale.
- are all the costs involved in the manufacture of goods (costs incurred inside the factory)
For example:
Direct material
Direct labor
Direct expenses
Variable production overheads
Fixed production overhead
Non-Production Costs
- are not directly associated with production of manufactured goods (costs incurred outside the factory).
- are taken directly to the income statement as expenses in the period in which they are incurred.
Such costs consist of:
Administrative costs
Selling and distribution expenses
Finance costs
Administrative Costs
These include all the costs involved in running the general administration department of an organization.
Examples of administrative costs include:
Depreciation of office buildings and equipment.
Office salaries, including salaries of directors, secretaries and accountants.
Rent, rates, insurance, lighting, cleaning, telephone charges and others.
Selling Costs
Selling costs include all costs incurred in promoting sales and retaining customers.
Examples of selling costs are:
Salaries and commission of salesmen and sales department staff.
Advertising and sales promotion, market research.
Rent, rates and insurance of sales offices and showroom.
Distribution Costs
Distribution costs include all costs incurred in making the packed product ready for dispatch and delivering it to the customer.
Examples of distribution overhead are:
Delivery costs
Wages of packers, drivers and dispatch clerks.
Insurance charges, rent, rates and depreciation of warehouse.
Finance Costs
Finance costs include all the costs that are incurred in order to finance an organization, for e.g., loan interest.
Non-production costs are taken directly to the income statement as expenses in the period in which they are incurred.
Functional Costs
(a) Production costs are the costs which are incurred by the sequence of operations beginning with the supply of raw materials and ending with the completion of the product ready for warehousing as a finished goods item. Packaging costs are production costs where they relate to 'primary ‘packing (boxes, wrappers and so on).
(b) Administration costs are the costs of managing an organization; that is, planning and controlling its operations, but only insofar as such administration costs are not related to the production, sales, distribution or research and development functions.
(c) Selling costs, sometimes known as marketing costs, are the costs of creating demand for products and securing firm orders from customers.
(d) Distribution costs are the costs of the sequence of operations with the receipt of finished goods from the production department and making them ready for dispatch and ending with the reconditioning for reuse of empty containers.
(e) Research costs are the costs of searching for new or improved products, whereas development costs are the costs incurred between the decision to produce a new or improved product and the commencement of full manufacture of the product.
(f) Financing costs are costs incurred to finance the business, such as loan interest
Fixed Costs
A fixed cost is a cost that is incurred for an accounting period and which, within certain activity levels, remains constant.
Examples of fixed costs include the salary of the managing director, the rent of a building, and the straight-line depreciation of machinery.
Variable Cost
A variable cost is a cost which tends to vary directly with the volume of output. As total costs increase with activity levels, the variable cost per unit remains constant. By their nature, direct costs will be variable costs. Examples of variable costs include raw materials and direct labor.
Stepped Fixed Costs
A stepped fixed cost is only fixed within certain levels of activity. The depreciation of a machine may be fixed if production remains below 1,000 units per month. If production exceeds 1,000 units, a second machine may be required, and the cost of depreciation (on two machines) would go up a step.
Other stepped fixed costs include rent of warehouse (more space required if activity increases) and supervisors’ wages (more supervisors required if number of employees increase).
Examples of Semi-Variable Costs Includes
Electricity and Gas Bills
Fixed cost = standing charge
Variable cost = commission on sales made
Salesman's Salary
Fixed cost = basic salary
Variable cost = commission on sales made
Costs of Running a Car
Fixed cost = road tax, insurance
Variable costs = petrol, oil, repairs
The High-Low Method is a technique of cost accounting, which is used to split mixed costs into variable and fixed components.
High-Low Method
When applying the High-Low method for our cost model, we start by calculating the Variable Cost per unit, via the following formula:
Where:
AC is Activity Cost, or the costs at certain activity level.
AU is Activity Units, or the units at the same activity level.
Once we have calculated the Variable Costs (VC) per unit, we can now use it to calculate the Fixed Costs (FC). There are two ways to do that, either using the Highest Activity or the Lowest Activity:
This way, we can arrive at a simple cost model:
Remember that when figuring out the highest and lowest data points, we should not look at cost, but rather at unit volumes, as they are the driver behind the cost. What this means is that if we have a cost of 1,000 at a unit volume of 200 and a cost of 980 at 210 units, our high data point should be at 210 units, even if the value at 200 exceeds that.
Example: The High-Low Method Using Revenues
The following information concerning sales revenues for a development, Cool Blue, for the last four months have been as follows.
Required:
Calculate the revenues that should be expected in month five when hits is expected to be 75,000 units. Ignore inflation.
Solution:
Example: The High-Low Method with Stepped Fixed Costs
The following data relate to the overhead expenditure of contract cleaners (for industrial cleaning) at two activity levels.
Required:
Calculate the estimated overhead expenditure if 22,000 square metres are to be industrially cleaned.
Solution:
Example: The High-Low Method with Inflation
You may be asked to use the high-low method when cost inflation is included. You need to deflate (reduce) all the costs to a base year before the high-low method can be applied.
Required:
Establish a linear equation for total costs per annum (at Year 1 prices) using the high-low method.
Solution:
Linear Equations
Also known as Equation of a Straight Line
Equation of a straight line: y = a + bx
The equation of a straight line is y = a + bx
‘a’ – the intercept, i.e., the value of y when x = 0
‘b’ – the gradient of the line y = a +bx (the change in y when x increases by one unit)
‘x’ - the independent variable
Equation of a straight line: y = a + bx
‘y’ – the dependent variable
Cost Equation
‘a’ is the fixed cost per period
‘b’ is the variable cost per unit
‘x’ is the activity level
‘y’ is the total cost = fixed cost + variable cost
Illustration
Y = 10,000 + 50X
What is the total cost of 500 units and 700 units?
Solution:
y = 10,000 + 50 x 500
y = $35,000
y = 10,000 + 50 x 700
y = $45,000
Therefore, we can see that the change in cost between these two levels of activity is $45,000 - $35,000 = $10,000
Raw Material, Work-in-Progress, Finished Goods.
Raw Materials
"Raw materials” are purchased and processed into goods. Chemicals, flour, and wood are examples of raw materials. Supplier-manufactured components and parts can also be used as raw materials.
Work in Progress
"Work in progress" is a term for things that are not finished yet. They have progressed from the purchased stage (raw materials), but they are not yet finished.
Finished Goods
"Finished goods” are complete and ready for sale.
????? ???????? = ????? ???? − ??????? ????????? + ??????? ?????????
???????? ???????? = ????? ???????? x ???????? ??? ????
???????? ????ℎ???? = ???????? ???????? − ??????? ????????? ?? ???????? + ??????? ????????? ?? ????????
Free inventory = inventory on hand + inventory on order – inventory scheduled for use
Bin cards just record quantity, while store ledger card records values. This system is a perpetual inventory system.

Course Overview
Costing is one of the most important and fundamental knowledge area in any business. The ultimate objective of any business is supposed to be profit and certainly profit is a function of cost. The success of a business does not solely depend on its revenue but also more importantly on how a business manages its costs.
Businesses fail not due to lack of revenues but due to uncontrolled costs. In order to control the business costs it is important to first understand the costs. Costs lie within products, processes, systems, departments and activities.
