Learn how to analyze workers’ compensation cost as a percentage of payroll month by month in Excel. In this lesson, you’ll see how to compare labor costs against payroll, spot high-risk periods, and build a clear visual that helps you monitor safety-related financial impact over time.

Start by identifying the three fields used in the analysis:
The video notes that even if your dataset includes employee names, hours worked, overtime, and other payroll details, this specific analysis only requires those three columns for the monthly view.
Before summarizing the data, create a total cost field for workers’ compensation.
This gives you the single workers’ comp cost field needed for the rest of the analysis.
Next, create the monthly structure for the summary table.
This creates the monthly list that drives the rest of the calculations.
Once the month list is ready, calculate payroll totals for each month.
This gives you the total payroll amount for each monthly period.
Now summarize the workers’ comp totals using the same monthly structure.
At this point, the table contains both payroll and workers’ comp totals for each month.
With both monthly totals in place, calculate the KPI percentage.
This creates the monthly Workers’ Compensation Cost % of Payroll series used in the chart.
The chart in the video includes a target line, so the next step is to build that into the table.
This makes the target line flexible without having to manually update every row.
With the summary table complete, build the chart.
This gives you the main KPI trend over time.
Instead of rebuilding the chart, the video shows a quick way to add the target series.
This adds the target line as a second series without having to manually edit chart ranges.
Once the chart is in place, clean up the title.
This makes the chart presentation-ready.
The video then adjusts the chart labels for a cleaner look.
This removes unnecessary decimal places and makes the chart easier to read.
To make the target line easier to distinguish from the actual KPI trend:
This helps the target act as a visual guide without overpowering the main data line.
Because the target series is linked to a single reference value, the chart can be updated quickly.
This is a simple way to test different thresholds.
Instead of labeling every point on the chart, the video highlights only the peaks.
This keeps the chart clean while still calling attention to the highest months.
If the labels are hard to read against the chart, adjust the formatting.
These small formatting touches make the important values stand out.
The final part of the video focuses on making the chart more compact and readable.
This helps the chart fit better on dashboards or presentations.
At the end, the completed chart shows:
The result is a simple monthly KPI chart that highlights peaks, valleys, and how actual performance compares to target.
Q1. What is Workers’ Compensation Cost % of Payroll?
Workers’ Compensation Cost % of Payroll is an HR and financial KPI that shows how much workers’ compensation expense you incur relative to total payroll. It helps businesses understand how workplace injuries and risk exposure affect labor costs and profitability.
Q2. Why is Workers’ Compensation Cost % of Payroll important?
This metric helps you connect employee safety performance with financial outcomes. When workers’ comp costs rise as a percentage of payroll, it can signal increased claims, higher risk exposure, or operational issues that may be affecting profitability.
Q3. How do I track Workers’ Compensation Cost % of Payroll in Excel?
You can summarize payroll and workers’ compensation costs by month, calculate the monthly percentage, and then visualize the results in an Excel chart. This makes it easier to identify trends, compare performance over time, and monitor whether your costs stay within target.
Q4. What does a target line add to this KPI chart?
A target line gives you a clear benchmark so you can quickly see whether your monthly workers’ compensation cost is above or below your desired threshold. It makes the chart more actionable and helps managers spot exceptions faster.
Q5. Who should monitor this KPI?
This KPI is useful for HR leaders, operations managers, finance teams, and business owners. It provides visibility into how employee-related risk affects both workforce management and overall financial performance.
Q6. Can this KPI help identify problem months or seasonal risk?
Yes. A month-by-month chart helps you spot peaks, valleys, and unusual spikes in workers’ compensation costs. That makes it easier to investigate whether certain periods, crews, or operating conditions are driving higher risk and expense.
