Cyber Risk Trend Calculator
Track cyber risk direction over time: period-on-period change, run rate, projected score and time to reach a target.
About Cyber Risk Trend Calculator
A single risk score is nearly meaningless; the direction and the rate are what tell you whether the programme is working. Comparing both to the previous period and to a year ago separates genuine improvement from seasonal noise, and the register burn-down is tracked independently because a falling score with a growing register usually means risks are being accepted rather than fixed. Boards fund trajectory, not position — a 62 that has fallen twelve points in a year is a well-run programme, and a 62 that has been 62 for three years is a stalled one.
Formulas
Cyber Risk Trend
monthlyRate = (currentScore − previousScore) ÷ periodMonths; monthsToTarget = (currentScore − targetScore) ÷ |monthlyRate| when the rate is negative.
- monthlyRate
- Points of risk reduction per month at the current pace
- projectedScore
- Current score plus twelve months at the current rate
- registerBurnRate
- Risks closed minus risks newly accepted per period
Register burn-down
registerMonths = openRisks × periodMonths ÷ (closed − new) — an infinite figure means the register is growing, whatever the score says.
- registerBurnRate
- Net risks removed per period
Worked example
With the default values below, Cyber Risk Trend Calculator returns Trend Direction of Improving consistently — risk is falling both this period and year on year. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 8 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax or fees or charges into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Cyber Risk Trend calculated?
monthlyRate = (currentScore − previousScore) ÷ periodMonths; monthsToTarget = (currentScore − targetScore) ÷ |monthlyRate| when the rate is negative. A single risk score is nearly meaningless; the direction and the rate are what tell you whether the programme is working. Comparing both to the previous period and to a year ago separates genuine improvement from seasonal noise, and the register burn-down is tracked independently because a falling score with a growing register usually means risks are being accepted rather than fixed.
Why does Cyber Risk Trend matter?
Boards fund trajectory, not position — a 62 that has fallen twelve points in a year is a well-run programme, and a 62 that has been 62 for three years is a stalled one.
What values do I need to enter?
This calculator takes 8 inputs: Current risk score, Score one period ago, Score a year ago, Length of one period, Target risk score, New risks accepted per period, Risks remediated per period, Open risks on the register. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
Why compare against both last period and last year?
Because quarterly movement is noisy — an audit, a new tool or a reclassification can move the score several points without anything real changing. The year-on-year figure is what confirms a trend.
What if the score improves while the register grows?
That is the classic warning sign that risks are being accepted rather than remediated, or that scoring is drifting. Trust the register burn-down over the score when the two disagree.
