Understanding Overapplied and Underapplied Manufacturing Overhead
Manufacturing overhead is a key concept in cost accounting that can significantly impact how companies analyze and report their production costs. One of the most important aspects to manage is whether overhead is overapplied or underapplied. Knowing how to detect, calculate, and correct for overapplied or underapplied overhead is critical for maintaining accurate business records and ensuring effective decision-making.
In this article, you’ll learn exactly how to tell if your manufacturing overhead is overapplied or underapplied, step-by-step methods for calculation, best practices, and practical insights. By the end, you’ll be able to recognize overhead variances, understand their causes, and know how to handle them efficiently.
What Is Manufacturing Overhead?
Manufacturing overhead refers to all the indirect costs required in the production of goods. This includes items such as:
- Indirect materials (e.g., lubricants, cleaning supplies)
- Indirect labor (e.g., supervisory salaries, quality control)
- Utilities for the factory (e.g., electricity, water)
- Depreciation on manufacturing equipment
- Maintenance and repairs on production equipment
These costs are not directly traceable to specific products, so they are pooled together and allocated to products using a predetermined overhead rate (POHR).
Predetermined Overhead Rate (POHR): The Foundation
Before you can identify if overhead is overapplied or underapplied, you need to understand the predetermined overhead rate. Here’s how it works:
- Estimate Total Overhead Costs for the upcoming period.
- Estimate Total Activity Level (usually in machine hours or labor hours) for the period.
- Calculate POHR:
- Formula:
POHR = Estimated Total Overhead Costs / Estimated Activity Level
During production, overhead is applied to products based on this rate, multiplied by the actual amount of activity (like machine hours used).
Actual vs. Applied Overhead: The Key Difference
- Applied Overhead: The estimated amount of overhead assigned to products using the POHR.
- Actual Overhead: The true costs incurred for overhead during production.
At the end of the period, you’ll compare these two numbers to determine if overhead has been overapplied or underapplied.
Overapplied and Underapplied Overhead Explained
What Is Overapplied Overhead?
- Occurs when the applied overhead exceeds the actual overhead incurred.
- In simple terms, you thought (and recorded) that your products needed more overhead cost than was actually spent.
What Is Underapplied Overhead?
- Occurs when the applied overhead is less than the actual overhead incurred.
- This means you allocated less overhead cost to your products than you actually paid.
Steps to Determine If Overhead Is Overapplied or Underapplied
Let’s break down the process into clear, actionable steps:
- Gather Data:
- Total applied overhead for the period.
-
Actual overhead costs incurred during the period.
-
Compare the Two Amounts:
-
Subtract the actual overhead from the applied overhead:
- Overapplied Overhead = Applied Overhead – Actual Overhead
- Underapplied Overhead = Actual Overhead – Applied Overhead
-
Interpret the Result:
- If the result is positive (applied is greater), overhead is overapplied.
- If the result is negative (actual is greater), overhead is underapplied.
Example:
| Applied Overhead | Actual Overhead | Result | |
|---|---|---|---|
| Scenario A | $100,000 | $90,000 | Overapplied ($10,000) |
| Scenario B | $100,000 | $110,000 | Underapplied ($10,000) |
Why Does Overapplied or Underapplied Overhead Occur?
Several factors can cause differences between applied and actual overhead:
- Inaccurate Estimates: Initial estimations of either overhead costs or activity levels may be off.
- Unexpected Events: Sudden repairs or spikes in utility costs can raise actual overhead.
- Production Variances: If production volume is higher or lower than expected, applied overhead can differ.
Impact of Overapplied or Underapplied Overhead on Financial Statements
Overapplied or underapplied overhead affects both your cost of goods sold (COGS) and your inventory valuations:
- Overapplied overhead means you have assigned too much cost to your products, inflating inventory values and lowering COGS.
- Underapplied overhead leaves some costs out of inventory, leading to understated inventory values and higher COGS.
Businesses must adjust these amounts for accurate financial reporting.
Disposing of Overapplied and Underapplied Overhead
At the end of the period, companies need to “dispose of” the balance in the overhead account. There are two main methods:
1. Close Entirely to Cost of Goods Sold
This is the simplest and most common method, especially when the variance is small.
– If Overapplied:
Decrease COGS by the overapplied amount.
– If Underapplied:
Increase COGS by the underapplied amount.
2. Prorate Among Inventory Accounts
If the balance is significant, it may be prorated among:
– Work in Process (WIP)
– Finished Goods
– Cost of Goods Sold
This method is more accurate but involves more calculations.
Journal Entries: Recording Overapplied and Underapplied Overhead
Let’s see how to record these variances in your accounting system.
For Overapplied Overhead
- Journal Entry:
Dr. Manufacturing Overhead
Cr. Cost of Goods Sold
This reduces your Cost of Goods Sold and brings the balance in overhead to zero.
For Underapplied Overhead
- Journal Entry:
Dr. Cost of Goods Sold
Cr. Manufacturing Overhead
This increases your Cost of Goods Sold, again balancing the overhead account.
Practical Tips for Managing Overhead Variances
Managing overhead is both an art and a science. Here are some practical tips:
- Review Estimates Regularly: Update your activity levels and cost estimates frequently.
- Monitor Overhead Activities: Track factory utilities, maintenance, and labor for unusual patterns.
- Analyze Variances Promptly: When you spot a significant variance, investigate and address the cause.
- Communicate Across Departments: Ensure production, accounting, and management are aligned on overhead expectations.
Common Challenges in Overhead Application
Navigating overhead can bring several challenges, such as:
- Volatility in Costs: Unexpected spikes in utilities or unplanned repairs can skew actual overhead.
- Inaccurate Forecasts: Imprecise estimates for activity levels or costs lead to larger variances.
- Allocation Base Selection: Choosing the wrong allocation base (labor hours vs. machine hours) can distort product costs.
- Excessive Complexity: Overcomplicating the overhead allocation process consumes resources and may confuse results.
Being aware of these pitfalls helps you design better systems for overhead control.
Benefits of Monitoring Overapplied and Underapplied Overhead
Staying on top of these variances brings tangible benefits:
- Improved Cost Accuracy: Ensures financial reports reflect true production costs.
- Better Pricing Decisions: Helps set prices that cover costs and maximize profitability.
- Enhanced Inventory Valuation: Leads to more accurate reporting of asset values.
- Identifying Inefficiencies: Highlights areas for potential cost savings and process improvements.
Best Practices for Effective Overhead Management
To prevent recurring problems, follow these best practices:
- Implement Standard Cost Systems: Use consistent, repeatable methods for allocating overhead.
- Leverage Technology: Use accounting software to automate tracking, calculation, and reporting.
- Conduct Regular Variance Analysis: Schedule monthly or quarterly reviews of overhead variances.
- Educate Your Team: Train staff in the importance and mechanics of overhead application.
Frequently Asked Questions (FAQs)
1. What does it mean if my overhead is overapplied?
If your overhead is overapplied, it means you applied more overhead costs to your products than you actually incurred. In other words, the overhead charged to products using the predetermined rate was more than the actual overhead expenses for the period.
2. How do I calculate if overhead is overapplied or underapplied?
Subtract the actual overhead costs from the applied overhead. If the result is positive, you have overapplied overhead. If negative, it’s underapplied.
Formula:
Overapplied/Underapplied Overhead = Applied Overhead – Actual Overhead
3. Why is it important to adjust for overapplied or underapplied overhead?
Adjusting for these variances ensures your financial statements accurately reflect production costs, inventory values, and profit. Ignoring them can lead to misleading financial reports and poor business decisions.
4. What causes underapplied overhead?
Underapplied overhead can result from higher actual costs (like repairs or utility spikes) or lower production activity than expected. Inaccurate estimates in the planning phase are a common culprit.
5. Can overapplied or underapplied overhead be carried to the next year?
Generally, no. Most companies close the balance to Cost of Goods Sold or allocate among inventory accounts at year-end. This practice maintains accurate financial records and prevents “carry-over” errors.
In Summary
Telling if manufacturing overhead is overapplied or underapplied starts with understanding the difference between what was applied vs. what was actually spent. Calculating the variance is straightforward: compare applied and actual overhead to see if you need to adjust cost records. Regular monitoring, prompt variance analysis, and adjustments are essential for accurate accounting and sound business decisions.
With these insights, you’re well-equipped to manage manufacturing overhead confidently and ensure your company’s financial statements paint a true and fair picture.
