How to use

Threshold and Top-K

The threshold is the lever you use to decide how wide the safety net is. The total savings number shows the trade-off: at lower thresholds, you’re spending more but preventing more turnover losses; at higher thresholds, you spend less but miss savings opportunities. The economically optimal threshold — the point where this trade-off yields the maximum net benefit — is key to maximizing your return.
Top-K is an alternative to the threshold that treats the highest-risk K% of employees. It’s often more profitable than a fixed threshold as it targets the highest-risk people, but it can be less transparent.

Intervention cost – average cost per person for your retention program
Effectiveness – chance the program prevents an otherwise likely leaver
Replacement cost – cost to replace a leaver (recruitment + onboarding + lost productivity)

Breakeven

A person becomes economically worth treating when
risk ≥ cost / (effectiveness × replacement_cost).

2) Pick an intervention strategy

Threshold: treat everyone above a chosen risk.
Top-K: treat the highest-risk K% (e.g., top 15%).
Coverage %: the portion of that group you can actually reach.

Note: The economically optimal threshold will often maximize net benefit, but you may adjust the threshold or Top-K percentage for practicality, budget constraints, or operational capacity.

3) Explore what-if levers

Reduce workload score – simulate capacity relief
Improve manager quality – simulate coaching/leadership support

The charts update instantly. Use the Δ Net savings and Risk change panels to judge ROI.

4) Interpret the results

Net savings (base) – expected savings with current settings before applying what-ifs.
Net savings (scenario) – expected savings after applying what-ifs.
Δ Net savings – difference between scenario and base (positive = better).
Threshold-free savings – reflects the probability-weighted expected value across the selected treated group (whether defined by Top-K or Threshold), providing a more comprehensive view beyond a single cut-off.

5) Decide & act

Start with Top-K targeting and a modest Coverage to pilot based on capacity.
