Risk Matrix Calculator (5x5)
Score any risk by probability and impact on a 5x5 matrix. Get an instant risk score, severity band, and recommended action - the fast way to triage and prioritize your risk register.
Actively mitigate now. Reduce probability or impact, prepare a contingency, and escalate to leadership.
A matrix ranks risks; it cannot budget for them. Put dollars on them with the EMV calculator, or analyze your plan in Incertive.
From a quick estimate to a real decision
A risk matrix is perfect for triage: it tells you which risks deserve attention first. What it cannot do is add risks together, put a dollar figure on them, or tell you the probability your whole project succeeds - the 1-5 scales are ordinal, not real numbers.
That is the quantitative step: turn rated risks into money with the EMV calculator, or into a full outcome distribution with Monte Carlo simulation. Incertive does both from your actual plan.
AI can describe your risk. Incertive calculates it.
This calculator gives you one estimate. Incertive runs thousands of Monte Carlo scenarios on your actual plan - success probability, sensitivity analysis, and a Go/No-Go you can defend, reproducibly, the same way every time.

How is a risk matrix score calculated?
A risk matrix scores a risk by multiplying its probability rating by its impact rating, each on a 1 to 5 scale. Score = probability x impact, giving a value from 1 to 25. Higher scores mean higher priority. The score maps to a severity band - Low, Medium, High, or Critical - that tells you how urgently to act.
What do the colors and bands mean?
This 5x5 matrix uses four bands: Low (score 1-4, green) means accept and monitor; Medium (5-9, yellow) means plan a mitigation and assign an owner; High (10-14, orange) means actively mitigate and escalate; Critical (15-25, red) means stop and address before proceeding. The bands turn a number into a clear action.
What is the difference between a risk matrix and a quantitative analysis?
A risk matrix is qualitative: it ranks risks on ordinal 1-5 scales, which is fast and great for triage but cannot add risks up, compute a dollar figure, or model how they interact. A quantitative approach like Expected Monetary Value or Monte Carlo simulation puts real numbers and probabilities on the risks so you can budget a contingency.
How many levels should a risk matrix have?
A 5x5 matrix is the most common because it gives enough resolution to separate risks without false precision. Some organizations use 3x3 for quick triage or 4x4. The important thing is that everyone agrees on what each probability and impact level means, so ratings are consistent across the team.
Can AI build my risk matrix?
AI can suggest risks and describe the matrix, but the score is a simple, exact calculation you should not leave to a chatbot that answers differently each time. Use this calculator for the score, then let Incertive turn your rated risks into a probability of success and a contingency figure - the quantitative step a matrix cannot do.
