Managerial Accounting 6.7: Using Variable Costing to Make Decisions
Summary
TLDRIn this educational video, Professor Kurt Heisinger from Sierra College explains the differences between absorption costing and variable costing in manufacturing. Absorption costing includes both fixed and variable manufacturing costs in inventory until sold, aligning with GAAP, whereas variable costing expenses fixed costs immediately, only inventorying variable costs. The key distinction lies in the treatment of fixed manufacturing costs. Variable costing, though not GAAP compliant, offers advantages for internal decision-making, enabling cost-volume-profit analysis and preventing profit inflation through increased production.
Takeaways
- 📚 Absorption costing includes both fixed and variable manufacturing costs in inventory until the goods are sold, complying with GAAP.
- 🏭 Fixed manufacturing costs, such as the lease on a factory, are considered part of the product costs in absorption costing.
- 🔄 Variable manufacturing costs, like direct materials, are included in inventory under absorption costing until sold.
- 💼 Nonmanufacturing costs are treated as period costs and expensed immediately, not included in inventory.
- 📊 Variable costing only includes variable manufacturing costs in inventory, expensing fixed costs as incurred, unlike absorption costing.
- 📉 Fixed costs in variable costing are recognized as period costs on the income statement, not carried in inventory.
- 🔑 The primary difference between the two costing methods is the treatment of fixed manufacturing costs.
- 📈 Variable costing supports effective cost-volume-profit analysis, aiding in determining break-even points and profit margins.
- 🚫 Variable costing prevents managers from inflating profits by increasing production and inventory levels, a potential issue with absorption costing.
- 🛑 While variable costing does not comply with GAAP, it is beneficial for internal decision-making and management purposes.
- 🧐 Both costing methods treat all other costs the same, highlighting that the key distinction lies in how fixed costs are handled.
Q & A
What is the main difference between absorption costing and variable costing in a manufacturing environment?
-The main difference lies in the treatment of fixed manufacturing costs. In absorption costing, both fixed and variable manufacturing costs are included in inventory until the goods are sold. In contrast, variable costing includes only variable manufacturing costs in inventory, while fixed manufacturing costs are expensed as incurred.
According to the script, which costing method complies with GAAP?
-Absorption costing complies with GAAP, as it includes all manufacturing costs, both fixed and variable, in the inventory until the goods are sold.
What are the examples of fixed manufacturing costs mentioned in the script?
-The script mentions the lease on the factory where products are produced as an example of fixed manufacturing costs.
What are the examples of variable manufacturing costs mentioned in the script?
-Direct materials that go into the product being made are given as an example of variable manufacturing costs.
How are nonmanufacturing costs treated under absorption costing?
-Nonmanufacturing costs, such as selling, administrative, and marketing costs, are treated as period costs under absorption costing. They are expensed in the period in which they are incurred and do not go into inventory.
Why might a company prefer to use variable costing over absorption costing?
-A company might prefer variable costing for internal decision-making purposes, as it enables effective cost-volume-profit analysis and prevents managers from increasing production solely to inflate profits.
What is the potential issue with using absorption costing and increasing production?
-The potential issue is that increasing production can lead to inflated profits by spreading fixed costs over more units in inventory, rather than recognizing them as expenses on the income statement, which might not reflect the actual sales performance.
How does variable costing help in cost-volume-profit analysis?
-Variable costing helps in cost-volume-profit analysis by clearly separating fixed and variable costs, allowing managers to determine break-even points, target profit points, and the margin of safety more accurately.
What is the primary distinction between absorption costing and variable costing as per the script?
-The primary distinction is the treatment of fixed manufacturing costs. In absorption costing, these are considered product costs and go into inventory, while in variable costing, they are treated as period costs and expensed immediately on the income statement.
Why does the script mention that variable costing does not comply with GAAP?
-The script mentions that variable costing does not comply with GAAP because it does not include fixed manufacturing costs in inventory, which is a requirement under GAAP for absorption costing.
How does the treatment of fixed manufacturing costs differ between absorption and variable costing in terms of financial reporting?
-In absorption costing, fixed manufacturing costs are included in inventory and are not expensed until the goods are sold. In variable costing, these costs are expensed immediately on the income statement as they are incurred, and do not contribute to the inventory valuation.
Outlines
🔍 Introduction to Costing Methods
In this introductory paragraph, Professor Kurt Heisinger outlines the purpose of the video, which is to explain the differences between absorption costing and variable costing in a manufacturing setting. The video will first discuss absorption costing, followed by variable costing, and then compare the two methods. The paragraph sets the stage for a deeper dive into costing principles that are essential for understanding financial accounting and managerial decision-making.

Highlights
Absorption costing includes all manufacturing costs, both fixed and variable, in inventory until goods are sold.
Fixed manufacturing costs refer to expenses like the lease on the factory.
Variable manufacturing costs include direct materials used in production.
Absorption costing complies with GAAP, making it a standard in financial accounting.
Nonmanufacturing costs, such as selling and marketing, are treated as period costs and expensed immediately.
Variable costing only includes variable manufacturing costs in inventory, expensing fixed costs as incurred.
Fixed costs like factory rent are expensed immediately under variable costing, not carried in inventory.
The primary difference between the two costing methods is the treatment of fixed manufacturing costs.
Variable costing is advantageous for internal decision-making despite not complying with GAAP.
Variable costing facilitates effective cost-volume-profit analysis, aiding in determining break-even points and target profits.
Variable costing prevents managers from inflating profits by increasing production unnecessarily.
Absorption costing can lead to issues if managers increase inventory levels to spread fixed costs, potentially inflating profits.
Variable costing treats fixed manufacturing overhead costs as period costs, expensing them immediately.
In absorption costing, fixed manufacturing overhead costs are considered product costs and go into inventory.
All other costs are treated the same in both costing methods, regardless of whether absorption or variable costing is used.
The choice between costing methods ultimately hinges on how fixed manufacturing costs are treated and the company's goals.
Transcripts
This is Kurt Heisinger, accounting professor at Sierra College and author of Managerial
Accounting. This video describes the difference between absorption costing and variable costing
in a manufacturing environment. We will start by looking at absorption costing on this
slide. And the next slide we'll take a look at variable costing and then we'll compare the two.
So absorption costing includes all manufacturing costs, fixed and variable, in inventory until the
goods are sold. So when we say fixed manufacturing costs, we're talking about for example, the lease
on the factory where we produce our products. And we're talking about variable manufacturing costs
we're talking about things like direct materials that go into the product that we are making. This
method does comply with GAAP so if you've had financial accounting you've followed this method,
this is absorption costing method. Also all nonmanufacturing costs, things like selling
costs, and administrative costs, marketing costs for example to promote our products, are treated
as period costs. And what that means is those costs are expensed in the period in which they
are incurred. They do not go into inventory, but they appear on the income statement as
an expense. So let's look at variable costing next. As the name implies, variable costing, this costing
method includes all variable manufacturing costs ininventory until the goods are sold,
just like absorption costing in terms of what we do with variable manufacturing costs, however the
difference is that all fixed manufacturing costs are expensed as incurred. Meaning they
are on the income statement as an expense in the period in which they are incurred. So costs again
like the rent on the factory building, that's a fixed cost, those costs are expensed as incurred.
They are not attached to the product, they do not go into inventory, they go directly to the
income statement as an expense. So with variable costing, variable manufacturing costs, they go
in to inventory until the goods are sold then they become expensed. But fixed manufacturing costs are
expensed immediately. This chart summarizes the difference between absorption costing and variable
costing. And you'll notice that really the only difference is with fixed manufacturing costs
and how those fixed manufacturing costs are fixed manufacturing overhead is handled. So if you look
at absorption costing, fixed manufacturing costs are considered to be product costs. And if you
look at variable costing, the fixed manufacturing costs are period costs. So you'll see those fixed
manufacturing costs here, we call them fixed manufacturing overhead cost, same thing
as fixed manufacturing costs, and you'll see here that they are period costs. Which means
that fixed manufacturing overhead in a variable costing scenario, go directly to the income
statement as an expense. That's what you see over here on this side. And with absorption
costing, fixed manufacturing overhead costs go into inventory, or considered to be product cost.
So that's the primary distinction. All other costs are treated the same, whether we use absorption
costing or variable costing. So it all comes down to how fixed manufacturing costs are treated.
What are the advantages then of using variable costing. We know that variable
costing does not comply with GAAP but it's great for internal decision making purposes. So variable
costing, it does lead to effective what we call cost-volume-profit analysis. If you go back to
my lectures on YouTube related to cost volume profit analysis, you'll see how it's helpful
to have fixed cost and variable cost broken out, so we can figure out things like break-even points, or
target profit points, or the margin of safety. So variable costing enables us to do that. And then
secondly, variable costing prevents managers from increasing production solely for the purpose of
inflating profit. There can be some real issues if we use absorption costing with increasing
production, and increasing our inventory levels, which is not always a good thing if we're not
selling the product. We increase our inventory levels and those fixed costs essentially are
kind of hidden in inventory and don't go to the income statement until the goods are sold, and it's
a way to spread out those fixed costs over more units in inventory on the balance sheet rather
than putting them in an expense account on the income statement. So it creates issues, potential
issues, for managers to inflate profit. And that's why some companies prefer to use variable costing.
