Cost Classification, Concepts and Terminology
Hello everyone! Welcome to the fascinating world of Cost Accounting. Don't worry, it's not as scary as it sounds! In this chapter, we're going to be like detectives for a business. Our mission? To figure out where all the money goes when a company makes a product or offers a service.
Understanding costs is super important. It helps a business set the right prices, control its spending, and make smart decisions to become more successful. Think of it like managing your own allowance – you need to know your costs (like for bubble tea or transport) to know if you can afford that new video game. Let's get started!
What is Cost Accounting and Why is it Important?
What is Cost Accounting?
Cost Accounting is the process of recording, classifying, and analysing a company's costs. It’s all about tracking the money spent to run the business, especially the money spent on creating products. It provides crucial information for managers inside the company to help them make decisions.
Why is it so Important for Decision-Making?
Cost accounting is the secret weapon for good managers. Here’s why:
1. Setting Selling Prices: To make a profit, a company must sell its products for more than they cost to make. Cost accounting tells them exactly what that cost is.
Example: A bakery needs to know the total cost of flour, sugar, electricity, and the baker's salary to decide the price of a cake.
2. Controlling Costs: By tracking all the costs, managers can spot areas where spending is too high and find ways to save money without sacrificing quality.
Example: If a factory's electricity bill suddenly goes up, managers can investigate why and maybe switch to more energy-efficient machines.
3. Planning and Budgeting: Businesses use past cost data to plan for the future. They can create a budget, which is a financial plan, to guide their spending for the next year.
4. Decision Making: It helps answer important questions like "Should we make this part ourselves or buy it from another company?" or "Should we accept a special order at a lower price?".
Key Takeaway: Cost accounting isn't just about recording numbers. It's about turning that financial data into useful information so managers can lead the company to success.
The Big Breakdown: Classifying Costs
Costs can be sorted into different groups, or "classified", in several ways. This helps us understand them better. It's like sorting your clothes: you can sort them by colour, by type (shirts, pants), or by season (summer, winter). We will look at three main ways to sort costs.
1. By Traceability: Direct Costs vs. Indirect Costs
This classification is about whether we can easily link a cost to a specific product.
Direct Costs
These are costs that can be easily and conveniently traced to a specific product, department, or activity (which accountants call a "cost object"). They are obviously part of the final product.
Analogy: Imagine you're building a wooden chair. The wood you use and the wages of the carpenter who physically puts that single chair together are direct costs. You know exactly how much wood went into that one chair.
Examples:
- Raw materials used (e.g., fabric for a dress).
- Wages of factory workers who assemble the product.
Indirect Costs
These are costs that are necessary for production but are NOT easily traced to a single, specific product. They are often shared among many products. Indirect costs are also known as overheads.
Analogy: For that same wooden chair, what about the rent for the whole factory? Or the salary of the factory supervisor who oversees 10 carpenters? You can't say exactly how much rent or supervisor salary "belongs" to that one single chair. These are indirect costs.
Examples:
- Factory rent.
- Electricity for the factory.
- Salary of a factory security guard.

Think about a bakery making a single birthday cake:
Direct Cost: The flour, eggs, and sugar used for THAT cake.
Indirect Cost: The electricity used by the oven that bakes many cakes all day.
2. By Behaviour: Fixed Costs vs. Variable Costs
This is all about how costs behave or change when the company produces more or fewer items. Don't worry if this seems tricky at first, the key is to look at the total cost.
Variable Costs
A variable cost is a cost whose total amount changes in direct proportion to the number of units produced. However, the variable cost per unit stays the same.
Analogy: You're selling cups of bubble tea. Each cup needs a plastic cup, a straw, tea, and pearls, costing $5 in total for materials.
- If you make 1 cup, your total variable cost is $5.
- If you make 100 cups, your total variable cost is $500.
The total cost changes, but the cost per cup is always $5.
Examples: Raw materials, packaging costs.
Fixed Costs
A fixed cost is a cost whose total amount stays the same, no matter how many units are produced (within a certain range). As you produce more, the fixed cost per unit goes down.
Analogy: The rent for your bubble tea shop is $10,000 per month.
- If you make 1 cup, the total rent is still $10,000.
- If you make 10,000 cups, the total rent is still $10,000.
The total cost is fixed. But the rent cost per cup is much lower if you sell 10,000 cups ($1 per cup) than if you only sell 1 cup ($10,000 per cup)!
Examples: Rent, insurance, annual salaries of managers.

Variable costs Vary in total.
Fixed costs have a Flat total.
3. By Function: Factory Overheads vs. Administrative Overheads
Remember we said overheads are just another name for indirect costs? Well, we can split them further based on where in the business they happen.
Factory Overheads
These are all the indirect costs related to the production process inside the factory. They are sometimes called 'manufacturing overheads'.
Think: If the cost happens IN the factory but isn't a direct material or direct labour, it's a factory overhead.
Examples:
- Rent for the factory building.
- Depreciation of factory machinery.
- Salary of the factory manager.
- Electricity and water used in the factory.
Administrative Overheads
These are all the indirect costs related to the general management and running of the business, usually happening in the main office, outside the factory floor.
Think: These are the costs to keep the whole company operating, not just the production line.
Examples:
- Rent for the head office.
- Salaries of accountants, HR staff, and the CEO's secretary.
- Office stationery (pens, paper, etc.).
- Legal and audit fees.
Common Mistake to Avoid
A common mistake is confusing a factory manager's salary with an office manager's salary. Remember to ask "WHERE does this person work?". If it's in the factory, their salary is a factory overhead. If it's in the main office, it's an administrative overhead.
Chapter Summary: Putting It All Together
You've learned the three main ways accountants classify costs. Let's recap!
1. Can you TRACE it to one product?
- Yes → Direct Cost (e.g., wood for one table)
- No → Indirect Cost / Overhead (e.g., factory rent)
2. Does the TOTAL cost CHANGE with production?
- Yes → Variable Cost (e.g., raw materials)
- No → Fixed Cost (e.g., insurance)
3. For Overheads, WHERE did the cost happen?
- Inside the Factory → Factory Overhead (e.g., factory supervisor's salary)
- Outside the Factory (in the office) → Administrative Overhead (e.g., accountant's salary)
Well done! Understanding these basic cost concepts is a huge first step in mastering accounting. Keep reviewing the examples, and you'll become a pro at classifying any cost that comes your way!
