Standard costing system

Welcome to the World of Standard Costing!

Hello there! Today, we are diving into one of the most important tools in a management accountant's toolkit: Standard Costing. If you have ever tried to stick to a budget or wondered how a massive company like McDonald's ensures every burger costs roughly the same to make, you are already thinking like a management accountant!

In this chapter, we will learn how businesses set "target" costs, why they do it, and how they use these targets to keep the business on track. Don't worry if this seems a bit technical at first—we will break it down step-by-step using simple examples from everyday life.

1. What exactly is a Standard Cost?

A standard cost is essentially a "planned" or "predetermined" unit cost of a product or service. Think of it as a benchmark or a yardstick. It tells the business: "This is what one unit should cost us to make under specific conditions."

A Simple Analogy:
Imagine you are baking a cake. You know that to make one cake, you should use 500g of flour and it should take you 30 minutes. If flour costs \$2 per kg, your "standard cost" for flour for one cake is \( \$2 \times 0.5kg = \$1 \). If you end up using 600g of flour because you spilled some, you have "varied" from your standard!

The Components of a Standard Cost

To build a standard cost for a product, we usually look at three main areas:
\n1. Direct Materials: How much raw material do we need and what should it cost?
\n2. Direct Labor: How many hours should it take to make, and what is the hourly pay rate?
\n3. Variable and Fixed Overheads: The "hidden" costs like electricity or factory rent allocated to each unit.

Quick Review:
\nStandard Costing is used for budgeting, inventory valuation, and performance measurement.

2. Why bother with Standard Costing?

You might think, "Why not just wait until the end of the month and see what we spent?" While that tells you the actual cost, it doesn't tell you if you did a good job. Here is why standard costing is helpful:

\n- Prediction: It helps in setting prices for customers before the product is even made.
\n- Control: By comparing what should have happened with what actually happened, we can find and fix problems (this is called Variance Analysis).
\n- Efficiency: It encourages staff to work toward a target.
\n- Simplicity: It makes bookkeeping easier because we can value our inventory at a consistent "standard" price.\n

3. The Four Types of Standards

In your exam, you will often be asked about the different types of standards. Think of these as different "levels of difficulty" in a video game.

A. Ideal Standards

These assume perfect conditions. No waste, no machine breakdowns, and no human errors.
\n- The Problem: They are often impossible to achieve, which can demotivate employees. It’s like trying to get 100% on every single exam you ever take—very stressful!

B. Attainable Standards

These are the most common. They assume a high level of efficiency but allow for normal spoilage, breaks, and machine downtime.
\n- The Benefit: They are challenging but "doable," which keeps staff motivated.

C. Basic Standards

These are long-term standards that do not change for years.
\n- The Benefit: They are great for seeing long-term trends (e.g., "Are we getting more efficient over a 5-year period?").
\n- The Problem: They become outdated quickly and aren't useful for current budgeting.

D. Current Standards

These are based on current levels of efficiency (how we are performing right now).
\n- The Problem: They don't encourage anyone to improve; they just reflect the "status quo."

Memory Aid: Use the acronym "A-B-C-I" (Attainable, Basic, Current, Ideal) to remember the four types!

Key Takeaway: Attainable standards are usually the best for motivating staff because they are realistic yet require effort.

4. How do we set these standards?

Setting a standard isn't just a "best guess." It requires careful research. Businesses use different methods:

For Materials:

The Standard Quantity is determined by looking at product blueprints or recipes. The Standard Price is determined by talking to the purchasing department about expected supplier prices and discounts.

For Labor:

The Standard Time is often set using work study or time-and-motion studies (watching how long it takes a skilled worker to do the task). The Standard Rate is based on the wage agreements with employees.

For Overheads:

These are usually based on a Budgeted Overhead Absorption Rate (OAR).
\n\( \text{OAR} = \frac{\text{Budgeted Overheads}}{\text{Budgeted Activity Level (e.g., hours)}} \)

Did you know? Standard costs need to be reviewed regularly. If the price of fuel suddenly doubles, your "Standard Cost" for shipping becomes useless!

5. The Standard Cost Card

A Standard Cost Card is a document that lists all the standard costs for one unit of a product. You will often see these in exam questions.

Example of a Standard Cost Card for a "Super Widget":
\n- Direct Materials: (2kg @ \$5/kg) = \$10
\n- Direct Labor: (3 hours @ \$12/hour) = \$36
\n- Variable Overheads: (3 hours @ \$2/hour) = \$6
\n- Total Standard Variable Cost: \$52
- Fixed Overheads: (3 hours @ \$4/hour) = \$12
- Total Standard Cost: \$64

Common Mistake to Avoid: Make sure you match the units! If the material is measured in kg but the price is given per gram, convert them before calculating.

6. Summary and Final Tips

Standard costing is all about planning and control. By setting a "Standard," we have a benchmark to measure our actual performance against later.

Key Summary Points:

- Standard Cost = The "should-be" cost of one unit.
- Attainable standards are usually the best for motivation.
- Standard Cost Cards summarize all the costs (Materials, Labor, Overheads) for one unit.
- Variance Analysis (which you will learn next) is the process of comparing Actual costs to these Standards.

Final Encouragement: Don't worry if the math feels a bit heavy at first. Once you understand that a standard is just a "planned recipe," the calculations start to make much more sense. Keep practicing those standard cost cards!
