Understanding Total Manufacturing Overhead Cost
When you run or manage a manufacturing business, knowing exactly how much it costs to produce goods is crucial. One of the most important components you have to consider is the manufacturing overhead. But what exactly is total manufacturing overhead cost, and how do you find it? Whether you’re a small business owner, production manager, or student, understanding how to calculate this figure is essential for proper pricing, budgeting, and profitability.
Let’s dive into what manufacturing overhead is, how to calculate it step-by-step, and why it matters for your business success.
What Is Manufacturing Overhead?
Manufacturing overhead, often called factory overhead or indirect production costs, includes all the costs associated with manufacturing a product that are not directly tied to raw materials or direct labor. These are necessary expenses that keep your production running but don’t form part of the actual product.
Common Examples Include:
- Factory rent or mortgage payments
- Depreciation on manufacturing equipment and facilities
- Utilities like electricity, water, and gas used in the factory
- Maintenance and repairs on production equipment
- Factory supplies (lubricants, cleaning materials, small tools)
- Quality control and inspection costs
- Salaries of supervisors and maintenance staff
- Property taxes and insurance for the production site
All these costs are considered indirect because they support the production process but aren’t traced to a specific product or batch.
Why Is Calculating Total Manufacturing Overhead Important?
Understanding your manufacturing overhead allows you to:
– Determine product pricing more accurately
– Pinpoint opportunities to improve efficiency
– Properly assess overall production profitability
– Build more precise budgets and forecasts
– Meet compliance and financial reporting requirements
When overhead costs aren’t captured accurately, you risk underestimating your real production expenses. This can lead to setting too-low prices, underfunding departments, or falling short of your profit goals.
How to Find Total Manufacturing Overhead Cost
Finding your total manufacturing overhead isn’t as complicated as it seems. With a systematic approach, you can gather all the necessary data and calculate the right number.
Step 1: List All Indirect Production Costs
Start by identifying every indirect cost involved in your manufacturing process. Focus on costs that:
– Are necessary for production to happen
– Aren’t directly linked to raw materials or hands-on labor involved in making each product
Types of Overhead to Consider:
- Fixed Overheads: These remain constant regardless of production volume (e.g., rent, supervisor salaries).
- Variable Overheads: These change with production levels (e.g., utility bills may rise if output increases).
- Semi-variable Overheads: Have both fixed and variable elements (e.g., maintenance costs might have a basic fee plus extra for frequent repairs).
Step 2: Gather the Data
For a specific period (often monthly or yearly), collect records of your overhead expenses. This typically involves pulling data from:
– Your accounting records (ledgers, invoices)
– Utility bills
– Payroll statements for non-direct labor
– Maintenance and repair logs
– Insurance documents
Step 3: Add Up All Overhead Expenses
Now, sum up all the amounts you’ve gathered from your indirect cost categories. This gives you your total manufacturing overhead for that period.
Simple Formula
Here’s the basic formula you can use:
Total Manufacturing Overhead Cost = Sum of All Indirect Manufacturing Expenses
Let’s see this in action with an example.
Example Calculation
Suppose, for the month of June, you have:
– Factory rent: $8,000
– Equipment depreciation: $2,500
– Utilities (electricity, water, gas): $1,200
– Maintenance and repairs: $600
– Supervisor salaries: $3,000
– Factory supplies: $400
Add them together:
$8,000 + $2,500 + $1,200 + $600 + $3,000 + $400 = $15,700
Your total manufacturing overhead cost for June is $15,700.
Step 4: Double-Check for Completeness
Review your calculations and expense categories to ensure you’ve included everything relevant. Double-check for any indirect costs you may have missed, as this step ensures accuracy.
Tips for Accurately Calculating Manufacturing Overhead
Getting your manufacturing overhead right is essential. Here are some tips and best practices to make sure your calculations are spot-on:
- Categorize Expenses Regularly: Set up your accounting system to tag and track indirect expenses that relate to manufacturing overhead.
- Use Accounting Software: Digital tools can help automate tracking and reduce errors.
- Distinguish Direct from Indirect Costs: Always be clear on what is a direct cost (materials, direct labor) versus indirect.
- Review Periodically: Overheads can change over time, so review categories and expenses at least quarterly.
- Allocate Costs Based on Usage: For utilities and mixed-use supplies, use meter readings or logical allocation bases for more accurate cost assignment.
Assigning Manufacturing Overhead to Products
Knowing your total manufacturing overhead is step one. Step two, especially for costing and pricing products, is allocating or applying overhead to each unit produced.
Common Allocation Methods
- Direct Labor Hours
- Divide total manufacturing overhead by total direct labor hours for the period.
- Apply the resulting overhead rate to each product based on how many labor hours it took.
- Machine Hours
- Similar to labor hours, but uses the number of machine hours spent producing goods.
- Units Produced
- Spread overhead evenly across all units produced.
Example (Direct Labor Hours):
If your total manufacturing overhead for July is $20,000 and you logged 1,000 direct labor hours:
- Overhead Rate = $20,000 / 1,000 = $20 per direct labor hour
If Product A took 4 labor hours, it’s allocated 4 x $20 = $80 in manufacturing overhead.
Benefits of Tracking and Calculating Manufacturing Overhead
Taking the time to understand and calculate your manufacturing overhead brings several key advantages:
- Improved Cost Control: Pinpoint areas where you can reduce unnecessary expenses.
- Accurate Pricing: Avoid underpricing products by factoring in all true costs.
- Greater Profitability: Prevent profit erosion by properly covering overhead in your pricing strategy.
- Better Planning: Forecast expenses more reliably and adapt budgets as needed.
- Strategic Decision-Making: Know when to invest in new equipment, negotiate supplier contracts, or scale operations.
Common Challenges in Calculating Manufacturing Overhead
Like any business process, calculating manufacturing overhead can have its bumps. Here are a few challenges you might face, with suggestions to overcome them:
1. Distinguishing Indirect Costs
Some expenses can seem indirect but are actually direct (e.g., labor for product assembly). Keep clear definitions within your company’s accounting practices.
2. Fluctuating Utility Costs
Utility bills can spike unexpectedly. To manage this, average utility costs over several months or use a flexible allocation method.
3. Mixed-Use Resources
Offices within your factory, for instance, may use shared electricity. Use logical allocation bases (e.g., square footage) to assign costs more fairly.
4. Overhead Creep
Small, overlooked expenses add up. Regularly review all expense categories and investigate unexplained increases.
Best Practices for Managing Manufacturing Overhead
Manufacturing overhead costs are unavoidable, but smart management can keep them under control. Consider these strategies:
- Regularly Audit Overhead Costs: Schedule periodic reviews to identify hidden or rising expenses.
- Negotiate Fixed Costs: Where possible, negotiate longer-term contracts for rent and utilities for cost predictability.
- Leverage Automation: Use technology to reduce manual work, control overtime, and flag inefficiencies.
- Encourage Team Awareness: Train your staff about what affects overhead and how they can contribute to efficiency.
- Continuously Benchmark: Compare your overhead percentages against industry averages to spot areas where you may be overspending.
Bringing It All Together
Calculating your total manufacturing overhead cost may not be the flashiest part of running a production business, but it’s foundational for healthy financial management. By tracking, categorizing, and periodically reviewing these costs, you can ensure your products are priced right, your profitability is protected, and your operational decision-making is robust.
If you want to get the best out of your production process, make manufacturing overhead calculation a regular habit. Use clear systems, check your math, and educate your team — your bottom line will thank you.
Frequently Asked Questions (FAQs)
What is the difference between manufacturing overhead and total manufacturing cost?
Manufacturing overhead includes only indirect production costs, such as factory rent, utilities, and supervisor salaries. Total manufacturing cost includes direct material, direct labor, and manufacturing overhead, representing all costs to make a product.
How often should I calculate my manufacturing overhead?
It’s best to calculate overhead monthly or quarterly. Regular reviews help you capture changes in expenses, adjust product pricing as needed, and keep your budgets accurate throughout the year.
What are some common mistakes in calculating manufacturing overhead?
Common mistakes include misclassifying direct costs as overhead, overlooking small recurring expenses, relying on outdated allocation bases (like old labor hour estimates), and failing to update for changes in rent or utilities.
Can overhead costs be reduced?
Yes! Regular audits, investing in energy-efficient equipment, renegotiating supplier contracts, consolidating shipments, and streamlining processes can help reduce your overhead burden over time.
Why do I need to allocate overhead to each product?
Allocating overhead ensures each product “pays its fair share” of total production costs. Without allocation, you may underprice goods, leading to lost profits, or misjudge which products are most profitable.
