Enter one manager at a time. Select their level, work mode and number of direct reports. The tool benchmarks each one instantly against global organization design standards and tells you exactly where your spans are healthy, overloaded or under-utilized.
How to Use This Calculator
- Select your industry from the dropdown at the top. This applies industry benchmark adjustments to every span range in the tool.
- Enter the average salary of a direct report in your organization. Without this, cost impact figures will not generate.
- Add each manager using the + Add Manager button. You can assess as many or as few as needed.
- For each manager, select their leadership level, work mode (co-located, hybrid or remote) and enter their actual direct report count.
- The tool recalculates instantly. No submit button is required.
- Click See a Working Example to explore a pre-filled scenario before entering your own data.
- For the most useful read, run the whole management layer at once rather than one manager in isolation. Patterns only become visible at scale.
How to Read the Results
- The Span Health Score ring shows the percentage of your managers sitting within their adjusted optimal range. Anything below 75% warrants a structured review.
- The Adjusted Optimal Range column is your benchmark. It reflects SHRM tier standards modified for your industry and each manager's work mode.
- The Boundary Distortion % tells you how far outside the healthy range a manager sits. Zero means they are within the defined standard.
- A Healthy status means no action is required. Both Moderate and Critical flags generate a cost estimate. Critical flags represent the largest exposures and should be prioritized.
- The Cost Impact figures are conservative estimates based on PwC and BCG productivity benchmarks. Treat them as a directional signal, not a precise forecast.
- Focus remediation on Critical flags first, then cluster Moderate flags that share the same manager level or function.
- A high under-span count typically signals unnecessary management layers added over time. A high over-span count typically signals under-investment in management headcount.
Disclaimer: Results are based on published industry benchmarks and should be used as a directional guide and not a substitute for a full organizational design review.

- Where span distortion is concentrated in specific roles, the Responsibility & Authority Gap Calculator can help identify whether those managers also carry a structural imbalance between accountability and decision rights.
