ERS Calculator

Toggle AIDEFEND defensive controls and adjust deployment context to see how they change the Effective Risk Score (ERS) in real time. For estimation and educational use. Unfamiliar with a term?

1

Set the scene

Pick the architecture and deployment context — or load the Finbot preset to start from the worked example.

2

Add your controls

Toggle the AIDEFEND techniques you've actually implemented. Each tag shows the sub-metrics it improves.

3

Read the result

Watch the ERS, severity, and layer breakdown update live on the right as risk drops.

Formula (simplified)

ERS = 1.5 + 8.5 × (1 − IVP) × CRMn × ACImod

Residual risk floor α = 0.15 (1.5 on 0–10 scale). Risk cannot be zeroed out.

This calculator uses a simplified affine calibration of the normative ERS formula (Framework Specification §5), anchored to the Finbot validation case (ERS = 10.0). Use the specification formula for assessments of record.
