Project Risk Expected-Cost Reserve

How to use this tool

1. Enter your own assumptions using a consistent currency and period.
2. Review the scenario outputs and compare alternative inputs.
3. Check the stated model limits before using the result in an operating plan.

Try this example

{
  "risk_a_probability": 20,
  "risk_a_cost": 10000,
  "risk_b_probability": 10,
  "risk_b_cost": 20000,
  "risk_c_probability": 30,
  "risk_c_cost": 5000,
  "buffer": 1000
}

Accuracy and scope

Expected-value reserve only, not a confidence percentile. Correlations do not change the expected sum but materially affect tail losses and contingency adequacy.
