Hello @Don Dom,
This risk score is calculated based on the weights you define in the calculator. According to your screenshot, the calculation currently considers only two parameters: Vulnerability Severity (80% weight) and Vulnerability Exploit Exists (20% weight). To see how this weighting affects your Risk Score and Risk Rating, please refer to the scenario in the "Risk Score Criteria" section. If you want to include other parameters, such as the EPSS Score, you will need to adjust the weights accordingly.
The final risk score is calculated using the following formula: (Vulnerability Severity Score * 0.80) + (Vulnerability Exploit Exists Score * 0.20)
The resulting output is detailed as follows
| Vulnerability Severity | Exploit Exists | Calculation | Final Risk Score |
| Critical | Yes | (100 * 0.80) + (100 * 0.20) | 100 |
| Critical | No | (100 * 0.80) + (0 * 0.20) | 80 |
| High | Yes | (75 * 0.80) + (100 * 0.20) | 80 |
| High | No | (75 * 0.80) + (0 * 0.20) | 60 |
| Medium | Yes | (50 * 0.80) + (100 * 0.20) | 60 |
| Medium | No | (50 * 0.80) + (0 * 0.20) | 40 |
| Low | Yes | (25 * 0.80) + (100 * 0.20) | 40 |
| Low | No | (25 * 0.80) + (0 * 0.20) | 20 |
| None | Yes | (0 * 0.80) + (100 * 0.20) | 20 |
| None | No | (0 * 0.80) + (0 * 0.20) | 0 |
