Formula Used
The calculator builds a residual risk index for each period, then evaluates trend direction, volatility, change percentage, and next-period projection.
1) Incident Factor
Incident Factor = min(Observed Incidents × 2, 10)
2) Base Weighted Score
Base Score = (Threat × Wt) + (Vulnerability × Wv) + (Impact × Wi) + (Asset × Wa) + (Incident Factor × Wn)
3) Residual Factor
Residual Factor = max(0.15, 1 − (Control Dampening × Control Effectiveness ÷ 100))
4) Residual Risk Index
Risk Index = Base Weighted Score × Residual Factor
5) Trend Measures
Overall Change % = ((Latest Risk − First Risk) ÷ First Risk) × 100
Volatility = Sample standard deviation of all period risk indices
Trend Slope = Linear regression slope across period numbers
Forecast = Regression estimate for the next period

Risk bands used here are Low under 4.00, Medium from 4.00 to 5.99, High from 6.00 to 7.49, and Critical from 7.50 upward.

How to Use This Calculator
Follow these steps to analyze directional cyber risk across reporting periods.
  1. Adjust the five scoring weights if your risk model values some factors more heavily than others.
  2. Set control dampening between 0 and 1 to define how strongly control maturity reduces residual risk.
  3. Enter six period labels, such as months, quarters, audit cycles, or release windows.
  4. For each period, fill threat likelihood, vulnerability severity, business impact, asset criticality, control effectiveness, and incident count.
  5. Press Analyze Risk Trend to display results below the header and above the form.
  6. Review the metric cards, detailed results table, and Plotly graph for direction, volatility, and forecast.
  7. Use the CSV and PDF buttons to export your calculated summary and detailed period analysis.
FAQs

1) What does this calculator measure?

It measures how residual cybersecurity risk changes across several reporting periods. It combines weighted threat, vulnerability, impact, asset criticality, incident pressure, and control effectiveness into a trend-focused risk series.

2) Why are weights normalized automatically?

Normalization keeps the scoring model consistent, even when your custom weight values do not sum to 1. This lets you focus on relative importance rather than manual balancing.

3) What is control dampening?

Control dampening determines how strongly control effectiveness reduces the base score. A higher dampening value means strong controls have more impact on lowering residual risk.

4) Why is there an incident factor cap?

The cap prevents unusually high incident counts from dominating the model. It keeps the score useful when one period has an extreme spike or a logging anomaly.

5) What does the trend slope mean?

The slope measures directional change over time. Positive slopes suggest rising risk, negative slopes suggest improvement, and values near zero indicate a relatively stable series.

6) How should I interpret volatility?

Volatility shows how uneven the risk series is. Higher volatility means larger swings between periods, which may signal unstable controls, inconsistent exposure, or changing threat conditions.

7) Is the forecast a guaranteed future value?

No. It is a simple next-period estimate based on linear regression. It is useful for planning, but it should support—not replace—expert judgment and current threat intelligence.

8) Can I use months instead of quarters?

Yes. The period labels are flexible. You can use months, quarters, sprints, audit windows, or any sequential review cycle that fits your security reporting process.
