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.
