When it comes to businesses and their inventory and accounting methods for managing it, there are a few different ways to approach the task. The three different options to value inventory/implement cost flow assumptions, include: Last In, First Out (LIFO); First In, First Out (FIFO); and Weighted Average Cost Accounting (WAC). This article will focus only on the WAC method.

Weighted Average Cost (WAC) Method

The Importance of Auditing

Auditing typically refers to an objective review of a company’s financial statements, which consists of the cash flow statement, the income statement and the balance sheet. It analyzes the level of accuracy that the business has characterized its financial records. The process looks at how a business documents investing, financing and operating ventures.

Depending on the type of audit and what it aims to accomplish, it can be conducted by internal employees or independent, third-party examiners like a Certified Public Accountant (CPA) firm or a government agency such as the Internal Revenue Service. When it comes to the United States, the Generally Accepted Accounting Principles (GAAP) is what auditors look to when analyzing financial statement preparation. External audits are guided by the American Institute of Certified Public Accountants’ (AICPA) Auditing Standards Board (ASB). The AICPA requires that the generally accepted auditing standards (GAAS) are followed by external auditors to ensure proper protocol is followed.

When it comes to regulations, the Sarbanes-Oxley Act of 2002 requires publicly traded companies to have their internal controls’ impacts reviewed. It also states that companies that do not implement and enforce their internal controls may be subject to criminal charges.

Defining Internal Controls

These can be thought of as how businesses can manage operations by regulating permissions, documentation, congruency, protection/safety and partitioning of responsibilities for business processes. These are broken into preventative and detective activities.

Sometimes referred to as protective activities, responsibilities are compartmentalized and distributed among different individuals to dissuade mistakes or deceit from occurring.

It also integrates highly detailed written procedures and validation procedures for further cautionary measures. It’s meant to verify that no sole person is able to approve, document or be responsible for monetary transactions and final products. Permitting invoices and validation of expenses are examples of internal controls. Only permitting appropriate access to the fewest employees necessary and the fewest required business equipment is one way to implement this type of internal control.

Detective Controls Defined

These are redundant systems that are put in place to intercept issues that might have fallen through the initial round of quality control measures. Looking to reconciliation procedures, which matches data in question against known accurate data sets, it’s used to fix discrepancies.

Internal Audits

This type of audit is usually conducted by the business’ employees, primarily performed as a way to evaluate internal operations and internal controls. It looks to identify any deficiencies or weaknesses in the business’ operations, often occurring before an external auditor reviews its financial statements. It’s also meant to review and identify any legal or regulatory compliance issues.

External Audits

This type of audit occurs when an independent auditor, such as a third-party CPA firm, assesses a business’ internal controls and financial statements. It is performed to provide an objective opinion that an audit conducted by the business itself cannot. With a “clean opinion” or “unqualified opinion” provided by the independent auditor, businesses can provide those looking at financial statements confidence that such financial statements are reliable. It enables the outside entity to focus on the financials, the business’ internal controls, etc. by providing a conflict-of-interest-free perspective.

Government Audits

This type of audit is done to ensure that businesses have accurately reported their taxable income to respective government agencies. This can include federal agencies such as the Internal Revenue Service (IRS) and Canada Revenue Agency (CRA), which are the U.S. and Canada’s respective tax collection agencies.

When an IRS audit has concluded its review, there may be a few different preliminary results and resulting paths. The tax return may see no modification. There may be a modification the taxpayer agrees to, which could result in additional money being owed. The third result occurs when the filer doesn’t agree with the change, and it is worked out through an appeal process.

Whether it’s an investor for a publicly traded company or a business looking for creditors for help with money, materials, etc., having audited financial statements provides confidence that they’ll see a return on their investment or a high likelihood of their debts being satisfied in the future.

Financial accounting is how accounting professionals document, compile and outline how a business performs financially over a discrete period of time. Unlike cost accounting, which is used primarily for internal short and long-term strategic planning, financial accounting focuses primarily on producing relevant documentation for outside parties interested in short- and long-term financial performance.

Small businesses, large corporations and nonprofits use the following financial statements produced for relevant parties: the Balance Sheet, the Cash Flow Statement and the Income Statement. When it comes to publicly traded companies, their financial accounting standards are overseen by generally accepted accounting principles (GAAP). It’s one way to provide a standardized means to communicate the business’s monetary details to potential and current shareholders, lenders, government oversight and tax enforcement agencies.

Balance Sheet

As the U.S. Securities and Exchange Commission (SEC) explains, the balance sheet is a financial statement that informs readers about a business’s assets, financial obligations and shareholders’ equity. It’s how a business documents its asset valuation, its financial obligations and cash holdings. It provides owners, lending institutions and investors a way to analyze a business. The current ratio shows the ratio of current assets to current liabilities. This is a way to evaluate a business’ ability to manage financial obligations over the next year. Shareholders’ equity represents how much cash would remain if the business satisfied all creditors and all assets were liquidated; whatever remains would be the property of the shareholders.

Income Statement

Released once a month, every quarter or once per year, an income statement reports revenue, expenses, and net earnings or losses of a company for a given period. A company’s net revenue is calculated by subtracting allowances for uncollectable accounts, discounts, etc. from a business’s gross sales or revenues. From there, subtract the cost of sales, or how much the lot of products or services cost to make for the accounting period, from the net revenues figure. This results in gross profit or gross margin. Depreciation, along with amortization, or the cost of machinery and equipment losing life over time, is subtracted from the gross profit figure.

From there, operating expenses, which aren’t directly attributable to product or service production but are running day-to-day operations, are deducted from the resulting gross profit figure. This number is now called income from operations or operating profit before interest and income expense. Depending on the number, the interest income or interest expense is either added or subtracted from operating profits to arrive at the operating profit before income tax. Finally, income tax is deducted, resulting in net profit (net income or net earnings) or net losses. For publicly traded companies, it gives investors insight as to how much the company is making per share, so-called “earnings per share” (EPS).

Cost accounting is a type of accounting that analyzes a business’ complete production costs by looking at both variable and fixed costs. This includes the concepts of marginal costing, lean accounting, standard costing and activity-based costing. It’s used by a business’ management to evaluate fixed and variable costs involved in the manufacturing operations.

The initial step is to assess and document such costs one-by-one. Once production is finished, it will contrast projected costs to what actual costs ended up being and see how processes can be improved. Management gleans information on how funds are used, revenue is earned, and where funds might be misdirected. It can help businesses create greater productivity and financial efficiencies after analyzing such information.

Looking at it more in-depth, there are different types of costs analyzed. The first is fixed costs, such as a monthly mortgage or lease payment, or those that are static regardless of the production level. The next is a variable cost that correlates directly with the production level. Operating costs can be either fixed or variable, depending on each business’ type of operation. Other types of costs include direct or directly connected; and indirect costs, which are costs such as administrative expenses that are less directly associated with production.  

Variable Cost Ratio

Variable Cost Ratio (VCR) looks at what percentage a business’ variable production costs is of its net sales. Businesses can calculate the VCR by:

VCR = Variable Costs / Net Sales. Net sales is a business’ gross sales after subtracting any discounting, customer returns and allowances.

It can also be calculated this way: VCR = 1 – Contribution Margin

If each widget’s variable unit cost is $40 and it sells for $200 individually, the VCR equals 0.2 or 20 percent. It’s also possible to be completed within a certain time frame. For example, if a single month’s total variable production costs are $6,000, and the business has revenues of $30,000 within that same month, the variable cost ratio is 0.2 or 20 percent.

The VCR shows if a company is able to earn a higher rate of revenues and a slower growth in input costs. It can help businesses determine when it hits an equilibrium between a loss and profit. It’s also important to note that fixed costs are excluded.

Marginal Costing

Marginal costing, or cost-volume-profit analysis, is a way to determine how much more it would cost a company to increase its manufacturing by one more widget.

It helps analyze the impact of varying levels of costs and volume on operating profit. This calculation looks at potentially profitable new products, sales prices to establish for existing products, and the impact of marketing campaigns. It assumes that the retail price and the variable and fixed costs per unit don’t change. It’s a way for businesses to calculate when they’ve developed a price point to cover all expenses. It also can indicate when the business can obtain profits at a particular price point and mix of manufacturing output. It’s a way for businesses to determine which levels are unprofitable, break-even and make a profit.

When it comes to determining how much sales volume a business needs to break even, the formula is as follows:

Sales Volume = Fixed Costs / Contribution Margin (Contribution Margin = Sales – Variable Costs)

If a business is looking to determine its break-even sales revenue figure, it must determine what its fixed costs are and its contribution margin. This calculation would be as follows:

$210,000 in fixed costs and a contribution margin of 30 percent = 210,000 / 0.30 = $700,000

However, it’s important to note that there’s no profit with the first calculation. If the business wanted to make $100,000 in profit, it would add that to the $210,000 in fixed costs. This would be calculated as follows: $310,000 / 0.30 = $1,033,333.33

Considerations of Marginal Costing/Cost-Volume-Profit Analysis

This formula tells a company if a widget is profitable. The contribution margin is what’s left over after each item or a lot of items is sold after deducting the variable costs for the respective number of units sold. When the contribution margin exceeds the fixed cost for the item or respective number of units sold, this signifies a profit. 

Companies that have the time and resources to analyze their performance beyond the traditional financial statements can see what’s right with their processes; but can more importantly, they can find out what’s wrong and how to fix it going forward.

Whether it’s tariffs, trade wars, or post-pandemic inflation caused by kink-ridden supply chains and what many experts believe to be excess money printing, inflation is an insidious drag on businesses’ operations. When it comes to energy’s contribution to inflation, the U.S. Energy Information Administration (EIA) reports that crude and natural gas prices in 2022 have increased on an annualized and weekly basis. Looking at the snapshot of 7/21/2022, WTI crude on the futures market was $96.35 a barrel. This was up more than $26 compared to 12 months ago, and $0.57 higher than a week earlier. For the same time frame, natural gas futures were $7.932/MMBtu, an increase of $3.973 from 12 months ago and an increase of $1.332 from a week earlier.

When it comes to businesses using any type of commodity, they’re faced with the question of how to raise retail prices when their prices increase. However, many business owners are hesitant to increase prices on their goods and services as they fear it will drive away customers. But in light of increasing input prices, not implementing price increases correctly will impact a business’s earnings and profitability.

As McKinsey & Company explains, there are many considerations why businesses have had trouble with mitigating costs in light of rising input costs. It’s important to monitor raw material costs with a fine-tooth comb. Businesses that bury costs of commodities, labor or tariffs under general accounting categories hide spikes in input costs due to factoring ancillary costs. If volatile input or uncontrollable factors, however, like tariffs can be monitored independently and in real time, businesses are more likely to be able to increase prices – and do so more gradually. With this in mind, McKinsey & Company highlighted four practices that businesses can implement to combat pressure from input costs and pushback from customers who question the reason for price increases.

1. Create a Database of Dynamic Costs

By looking at historical records going back as far as 36 months, businesses can determine trends and keep track of increases or decreases of input materials to share with the sales and customer service department, who can then communicate with customers. Along with looking at how contracts are written and if there are escalator clauses that permit conditions to adjust for increases in input materials, taking steps to accurately measure the impact of raw material costs can be helpful for price increase considerations.

It could look at costs by department. If a plating department at a manufacturing company plates 50,000 pieces of metal a month, incurs $200,000 of direct material costs and has $50,000 in labor and overhead costs, it can be broken down into a per unit cost of $4 for materials and $1 of labor and overhead costs. If the per unit cost of materials fluctuates, investigation can occur through the supply chain from the supplier to the price of futures contracts to see if prices can be negotiated or must be increased for customers.

2. Mind the Economy

Businesses are advised to keep an eye on current economic conditions. This is how companies can set a dynamic pricing strategy. Building on the first step, it’s advised to index prices to those of commodities to reduce the lag time between when companies experience changes in costs for their input materials and when retail prices actually reflect the true cost to the company. Be it fuel, wood, coffee or metals, understanding how the price of commodities fluctuates in real time is essential to determine when and how to adjust prices for retail customers. It also can help businesses determine how competitors are adjusting their pricing to customers, how far prices could increase, and how to augment delivery of goods or services to stay competitive and profitable.  

In addition to escalation clauses, companies adapting to changing input material prices could, for example, introduce shorter-term contracts, look for more competitive suppliers, or substitute different but equal quality/performance materials.

3. Coaching Staff to Educate and Explain Price Fluctuations

Continual evaluations for sales teams are imperative. Supervisors must see what accounts have (and have not) been informed of price increases. They should focus on what accounts have accepted price increases (and what level of price increases have been accepted). They also should look at what accounts are likely to accept price increases and what accounts are not likely to accept price increases. Businesses also must factor in the business cycle for the sales process and how each account is performing relative to its price increase targets due to cyclical increases in input commodity prices and interest rates for financing availability. Ongoing coaching should be implemented to identify major issues and ways to resolve them. Anticipating and preparing sales representatives for customer questions through role playing can help better prepare employees to explain why price increases are a part of doing business.

4. Managing Performance

Businesses must play the long game after products or services have been priced accordingly to commodity and input prices. Since inflation follows the economic cycle, upside and downside pricing dynamics can catch companies off guard. Consistently updated product or service pricing systems and prepared sales teams can lead to more profitable margins and hopefully the ability to weather volatile and long-term price spikes.

Much like the price of commodities and labor fluctuate based on dynamic market conditions, finding ways to adapt one’s business practices can increase chances of surviving and thriving in a challenging economy.
