What Goes Into a Labor Cost Calculation?

Labor cost in electronics manufacturing refers to the total expenses associated with workers involved in the production process. Accurate labor cost calculation is critical for competitive pricing and profitability. As reported by the Global Electronics Association, 54% of electronics manufacturers report rising labor costs, making accurate calculations essential for remaining competitive. To accurately calculate labor costs, you need to consider both direct and indirect labor, as well as other operational factors.

What Counts as Labor?

Labor includes any employee time spent on the production process. In electronics manufacturing, labor can be categorized as:

• Direct Labor: Employees who physically work on production, such as assembly line workers, engineers, and testers.
• Indirect Labor: Employees who provide support services, like supervisors, machine maintenance staff, and quality control personnel.

Calculating labor costs involves summing both direct and indirect labor hours, multiplied by their respective wage rates. Direct labor typically has a more direct impact on the product, while indirect labor contributes to overall operational efficiency.

What You Must Collect Before You Calculate

Before you begin, gather the following data:

1. Wage rates for each worker or group of workers.
2. Labor hours for direct and indirect labor, broken down by product or operation.
3. Overtime rates, if applicable, for workers exceeding their standard hours.
4. Employee benefits and additional costs, like taxes, insurance, and bonuses.

This data will give you the raw material for calculating labor costs and enable accurate quoting and cost analysis.

Formula to Calculate Labor Cost in Electronics Manufacturing

To calculate labor cost in electronics manufacturing, sum up both direct labor and indirect labor costs. The formula for calculating labor cost is:

Be sure to include overhead costs such as benefits, insurance, and taxes in the final calculation to ensure complete accuracy.

How Labor Cost Accuracy Affects Pricing, RFQs, Win Rate, and Margin?

Labor cost directly impacts product pricing, RFQs, and overall margins. Inaccurate labor costs can lead to underpricing or overpricing products, affecting both profitability and competitive edge. For instance, labor productivity and unit labor costs in electronics manufacturing have grown by 3.3% from 2019 to 2024, emphasizing how dynamic and critical labor cost management is

Accurate labor cost calculation helps create precise quotes, ensuring you cover all your expenses, boosting win rates, and maintaining healthy margins. This can also affect RFQs (Request for Quotes) since inaccurate pricing might make your offer uncompetitive.

• Pricing Accuracy: Accurate labor cost calculation helps create precise quotes, ensuring you cover all your expenses.
• Win Rate: If your labor cost estimates are too high, you might lose the bid, while if they’re too low, you risk undercutting your margins.
• Margins: Labor is a large part of the cost structure. If not properly calculated, it can significantly cut into your profit margin.

How to Build a Loaded Hourly Labor Rate?

A loaded hourly labor rate includes not just wages, but also additional costs like benefits, taxes, insurance, and overhead. To calculate it:

1. Add all employee benefits (health insurance, retirement contributions, etc.).
2. Include taxes and employer contributions (social security, workers' compensation).
3. Factor in overhead costs related to maintaining the workforce (e.g., recruitment, training).

This rate provides a clearer picture of how much it costs to employ a worker and helps in the accurate calculation of labor costs per unit.

How to Set Standard Time per Unit by Process Steps?

Setting the standard time per unit is essential for calculating accurate labor costs, especially in manufacturing processes like electronics production. This standard time represents the average time it takes to produce one unit of product under normal working conditions, factoring in labor, equipment, and materials. Here's a step-by-step approach to setting the standard time per unit by process steps:

1. Conduct a Time Study

The first step in setting the standard time is performing a time study. This involves observing and recording the time it takes for workers to complete each step in the production process. Ideally, the study should be conducted under normal production conditions, using workers with average skill levels and equipment that is in good working order.

• Time Study Methods: Use tools like a stopwatch or software to track the time spent on each process step (e.g., assembly, testing, packaging).
• Multiple Observations: Conduct multiple observations to account for variations in worker efficiency and machine performance. Typically, a sample of 20-30 cycles is used to gather a reliable time estimate.

2. Break Down the Production Process into Steps

Split the production process into individual, measurable steps. For example:

• Assembly
• Inspection
• Testing
• Packaging

Each of these steps will have its own time requirement, which contributes to the overall standard time per unit.

3. Calculate the Average Time for Each Step

Once you've gathered enough data from your time study, calculate the average time per step. For example, if you conducted 30 observations of a particular step and the times ranged from 2.5 minutes to 3.5 minutes, the average time would be calculated as the mean of all observed times.

4. Factor in Allowances for Delays

Not all time is productive, and some delays are inevitable (e.g., machine downtime, setup time, break times). Add an allowance factor to the standard time to account for these non-productive times. Common allowances might range from 10% to 20% of the observed time, depending on the complexity of the process.

For instance, if your average time for a step is 3 minutes, and you add a 15% allowance, the adjusted time for that step would be:

Adjusted Time = 3 × (1 + 0.15) = 3.45 minutes

5. Add Times for All Steps

Once you have the adjusted time for each process step, sum them up to get the total standard time per unit. For example, if the steps are assembly (5 minutes), testing (2 minutes), and packaging (3 minutes), the total standard time per unit would be:

Total Standard Time = 5 + 2 + 3 = 10 minutes

6. Review and Adjust for Production Variability

Standard times should be periodically reviewed and adjusted based on changes in production conditions, such as improved worker efficiency, machine upgrades, or changes in production volumes.

Why It Matters:

Setting a standard time per unit is critical because it:

• Provides a benchmark for labor cost calculations.
• Helps in optimizing production efficiency by identifying areas where time can be reduced.
• Assists in pricing accuracy, ensuring products are quoted at a competitive price while covering all production costs.
• Facilitates performance monitoring, allowing you to track if actual production time aligns with the standard time.

This method ensures that all aspects of labor, equipment, and potential delays are accounted for when calculating labor costs, making your cost estimates more accurate and reliable.

How to Treat Yield, Rework, and Scrap in Labor Cost?

In electronics manufacturing, yield, rework, and scrap are important factors that affect labor costs. Here's how each one should be treated when calculating total labor costs:

1. Yield

Definition: Yield refers to the percentage of products produced that meet quality standards without requiring rework or scrap.

Impact on Labor Cost: If the yield rate is low, it means more units are being rejected or needing further work. This increases the labor time required per unit, as more labor hours are spent on fixing defective products. Lower yield means higher labor costs per unit produced because labor is being spent on products that won’t contribute to the final deliverables.

2. Rework

Definition: Rework involves correcting defective products that didn’t meet quality standards in the initial production process. This can involve labor to fix issues, redo tests, or replace faulty components.

Impact on Labor Cost: Rework directly increases labor costs since additional hours are required to bring defective products up to standard. It’s crucial to account for rework labor as part of the overall labor cost. Depending on how frequent rework is, this can significantly increase the total labor cost for a product, especially if defects are widespread or take considerable time to fix.

3. Scrap

Definition: Scrap refers to products or components that are discarded during production because they cannot be repaired or reused. This could be due to defects, damage, or material waste.

Impact on Labor Cost: Scrap directly increases labor costs because labor is spent on creating products that ultimately have no value. When scrap rates are high, labor costs are effectively wasted on products that won’t be sold. It’s important to factor in the labor used in creating scrap parts when calculating total labor costs to reflect the inefficiency of the production process.

How to Calculate the Impact of Yield, Rework, and Scrap on Labor Cost?

Factor in extra labor for rework, scrap time, and lower yield rates to accurately calculate labor costs and adjust pricing accordingly. Go below and understand well:

1. Include Extra Labor for Rework: When calculating labor costs, ensure that the time spent on rework is accounted for separately. If rework is common, this could add significant labor costs to each unit.
2. Account for the Labor Used in Scrapped Parts: For scrap, the labor spent on producing defective parts should be included in the total labor cost calculation. Even though these parts are discarded, the time spent on them still contributes to the overall production cost.
3. Adjust Labor Rates for Lower Yield: If the yield is low, recalibrate your labor cost per unit to reflect the additional time required to produce the acceptable units. This means factoring in the additional labor hours spent on rejected units or on fixing them.

For example, if you are producing 1,000 units, but your yield rate is only 80%, you are producing 200 defective units that need to be scrapped or reworked. This additional labor time for fixing defects or handling scrapped units should be included in the labor cost for the remaining 800 units.

Table: Example of Yield, Rework, and Scrap in Labor Cost Calculation

Explanation:

• In the standard yield case, 200 units are defective but require 2 hours of rework per unit. There’s no scrap time.
• In the low-yield case, 400 units are defective, which increases the rework time to 3 hours per unit, and 0.5 hours are added for handling scrap.

Prototype vs Mid Volume Example

In electronics manufacturing, prototype and mid-volume production runs have distinct labor cost structures. Here’s how they differ:

Prototype Production:

• Setup Time: In prototype production, setup time is typically higher due to the need for specialized equipment, tooling, and testing. The process is often experimental and involves design adjustments, so it's not as efficient as mid-volume production.
• Labor Time Per Unit: The labor time per unit is longer in prototype production. Engineers and assembly workers may need to perform more manual tasks, troubleshoot, or adjust designs on the fly. The lack of standardized processes and lower production speed increase the labor cost per unit.
• Output: The number of units produced is low in prototype runs, which means labor costs are spread over fewer units, driving the cost per unit higher.

Mid-Volume Production:

• Setup Time: Setup time in mid-volume production is much shorter compared to prototype runs. By this stage, the design and processes are more refined, and there is less need for adjustments.
• Labor Time Per Unit: Labor time per unit is reduced in mid-volume production. The processes are more standardized, and the workforce becomes more efficient as they repeat similar tasks, which reduces the time required for each unit.
• Output: The production volume is significantly higher, which allows labor costs to be spread over more units. This means lower labor costs per unit, making mid-volume production more cost-effective.

Common Mistakes That Break Labor Costing

Mistakes in labor costing lead to inaccurate pricing, reduced profitability, and missed opportunities, ultimately harming competitiveness, margins, and overall financial performance. Here is a breakdown of common mistakes that break labor costing:

1. Failing to Include All Labor Types
   Ignoring indirect labor (such as supervisors and maintenance staff) can result in incomplete cost calculations, leading to inaccurate pricing.
2. Not Accounting for Overhead Costs
   Overhead costs like training, insurance, and facility maintenance are often overlooked. These should be factored into the labor cost to avoid underestimating overall expenses.
3. Misjudging Labor Hours
   Inaccurately estimating the number of labor hours required for production can significantly distort cost calculations, especially if based on outdated or generic data.
4. Overlooking Overtime and Shift Premiums
   Not including overtime pay or shift premiums (for evening or night shifts) can lead to lower-than-actual labor cost estimates, especially in high-demand production periods.
5. Neglecting Time for Downtime and Delays
   Downtime (due to machine failure, material shortages, etc.) is a common factor that should be included in labor cost estimates. Ignoring this can lead to inaccurate production cost predictions.
6. Ignoring Employee Benefits
   Only accounting for wages without considering employee benefits like health insurance, vacation pay, or retirement contributions can understate labor costs by a significant margin.
7. Failure to Track Labor for Rework or Scrap
   Labor used for reworking defective products or for scrap should be added to labor costs to reflect the total workforce investment in production.
8. Over-relying on Historical Data Without Adjustments
   Using historical data without considering current production conditions or changes in labor rates can lead to inaccurate costing. Regular updates and adjustments are necessary.
9. Not Factoring in the Variability of Labor Skills
   Labor costs vary based on the skill levels of workers. Assuming all workers cost the same, regardless of skill or experience, can lead to significant miscalculations.
10. Underestimating the Impact of Yield Rates
    Labor costs should reflect the yield rate of the production process. If the yield is low, more labor is required to meet production targets, increasing overall labor costs.

By avoiding these mistakes, you can ensure more accurate labor cost calculations, leading to better pricing, higher win rates, and improved profit margins.
