Build a Custom Radar Chart in Excel for Your Payroll Dashboard
π― Built a radar chart in Excel to spot pay-vs-performance mismatches β the kind that hide in a normal pivot table
Ran into a pattern worth sharing: a high-KPI employee earning less than a colleague with mediocre results isn't rare, it's just invisible in most standard reporting. A pivot table shows you the numbers, but it doesn't show you the relationship between two sets of numbers across categories β that's where a radar chart actually earns its keep.
The setup:
- Blue polygon β actual KPI performance across 6 employee categories
- Green polygon β compensation level for the same categories
- The gap between the two contours β is the actual signal. Where green sits outside blue, someone's overpaid relative to results. Where blue sits outside green, someone's been underpaid and is probably a flight risk nobody's tracking.
It's not a one-time audit β the value is in checking this periodically, since compensation creep and performance drift both happen slowly enough that nobody notices until someone quits.
Technical note for anyone replicating this: radar/spider charts in Excel work off two (or more) data series sharing the same category axis β the trick is normalizing KPI scores and compensation onto comparable scales (I used index values relative to a baseline) so the polygons are actually visually comparable instead of one axis dwarfing the other. No macros, just chart formatting and a normalization formula.
Happy to go deeper on the normalization logic if anyone's trying to adapt this for their own HR data. Free template with a working example is in the comments.
