What Is Cost Allocation?

What is cost allocation?

Cost allocation is the process of identifying and assigning costs to business objects, such as products, projects, departments or individual company branches. Business owners use cost allocation to calculate profitability. Costs are separated or allocated, into different categories based on the business area they impact. These amounts are then used in accounting reports. 

For example, say you’re a small clothing manufacturer. Your product line’s cost allocation would include materials, shipping and labor costs. It would also include a portion of the operation’s overhead costs. Calculating these costs consistently helps business leaders determine if profits from sales are higher than the costs of producing the product line. If not, it can help the owner pinpoint where to raise prices or cut expenses.

For a larger company, cost allocation is applied to each department or business location. Many companies also use cost allocation to determine annual bonuses for each area.

Types of costs

If you’re starting a business, the cost allocation process is relatively straightforward. However, larger businesses have many more costs that can be divided into two primary categories: direct and indirect costs:

• Direct costs: These expenses are directly related to a product or service. In your business’s financial statements, these costs can be linked to items sold. For example, in a small clothing manufacturing business, direct costs can include the following:
  • Purchased inventory
  • Materials used to make inventory
  • Supplies
  • Direct labor costs for employees who make inventory
• Indirect costs: These expenses are not directly related to a product or service but are necessary to create the offering. Indirect costs can include the following:
  • Payroll for those who work in operations
  • Manufacturing overhead, including rent, insurance and utilities costs
  • Other overhead costs, including expenses that support the company but aren’t directly related to production, such as marketing and human resources

What is a cost driver?

A cost driver is a variable that affects business costs, such as the number of invoices issued, employee hours worked or units of electricity used. Unlike cost objects, such as units produced or departments, a cost driver reflects the reason for the incurred cost amounts. 

How to allocate costs

While cost objects vary by business type, the cost allocation process is the same regardless of what your company produces. Here are the steps involved.

1. Identify your business’s cost objects.

Determine the cost objects to which you want to allocate costs, such as units of production, number of employees or departments. Remember that anything within your business that generates an expense is a cost object. Review each product line, project and department to ensure you’ve gathered all cost objects for which you must allocate costs.

2. Create a cost pool.

Next, create a detailed list of all business costs. Categories should cover utilities, business insurance policies, rent and any other expenses your business incurs.

3. Choose the best cost allocation method for your needs.

After identifying your business’s cost objects and creating a cost pool, you must choose a cost allocation method. Several methods exist, including the following standard ones: 

• Direct materials cost method: This cost allocation method assumes all products have the same allocation base and variable rate.
• Direct labor cost method: This cost allocation method is most helpful if labor costs can be allocated to one product or if expenses vary directly with labor costs.
• High/low method. This cost allocation method is best if you have more than one cost driver and each driver has different fixed or variable rates.
• Step-up or step-down method: With this cost allocation method, departments are first ranked and then the cost of services is allocated from one service department to another in a series of steps. 
• Full absorption costing (FAC): This cost allocation method combines direct material and direct labor costs with a predetermined FAC rate based on company historical data or industry standards.
• Variable costing: Consider this cost allocation method if your business has many variable cost allocations (costs that vary by quantity) and uses significant direct labor.

4. Allocate costs.

Now that you’ve listed cost objects, created a cost pool and chosen a cost allocation method, you’re ready to allocate costs. 

Here’s a cost allocation example to help you visualize the process: 

Dave owns a business that manufactures eyeglasses. In January, Dave’s overhead costs totaled $5,000. In the same month, he produced 3,000 eyeglasses with $2 in direct labor per product. Direct materials for each pair of eyeglasses totaled $5.

Here’s what cost allocation would look like for Dave:

Direct costs: $5 direct materials + $2 direct labor = $7 direct costs per pair

Indirect costs: Overhead allocation: $5,000 ÷ 3,000 pairs = $1.66 overhead costs per pair

Direct costs: $7 per pair

+ Indirect costs: $1.66 per pair

Total cost: $8.66 per pair

As you can see, cost allocation helps Dave determine how much he must charge wholesale for each pair of eyeglasses to make a profit. Larger companies would apply this same process to each department and product to ensure sufficient sales goals.

5. Review and adjust cost allocations.

Cost allocations are never static. To be meaningful, they must be monitored and adjusted constantly as circumstances change.

What are the benefits of cost allocation?

Accurate, regular cost allocation can bring your business the following benefits: 

• Helps you run your business: The information you glean from cost allocation reports helps you perform vital functions like preparing income tax returns and creating financial reports for investors, creditors and regulators. 
• Informs business decisions: Cost allocation is an excellent business decision tool that can help you monitor productivity and justify expenses. Cost allocation gives a detailed overview of how your business expenses are used. From this perspective, you can determine which products and services are profitable and which departments are most productive. 
• Helps produce accurate business reports: Tax accounting, financial accounting and management accounting all require some kind of cost allocation. This information is the foundation of accurate business reports. 
• Can reveal accurate production costs: Knowing what it costs to create a product, including all expenses allocated to it, is essential to making good pricing decisions and allocating resources efficiently.
• Helps you evaluate staff: Cost allocation can help you assess the performance of different departments and staff members. If a department is not profitable, staff productivity may need improvement. 

Common cost allocation mistakes

To get the most from cost allocation, avoid these common mistakes:

• Equal or inflexible allocation: Cost allocation is not as simple as allocating any given cost over different product lines or departments. Some cost objects require more time, expense or labor than others, for example.
• Missing costs: Costing is meaningless if it doesn’t include all expenses. Don’t forget costs, such as overhead, time spent and intangible expenses.
• Failing to adjust as needed: Costs and priorities in business are changing constantly. Be sure your cost allocations are monitored and adjusted to meet your information needs.
• Not considering fluctuating revenue with indirect costs: If your business is seasonal or fluctuates over time, it’s important to account for that when allocating costs. 

Cost allocation and your business

Even if you operate a very small business, it’s essential to properly allocate your expenses. Otherwise, you could make all-too-common mistakes, such as charging too little for your product or spending too much on overhead. Whether you choose to start allocating costs on your own with software or with the help of a professional small business accountant, cost allocation is a process no business owner can afford to overlook.
