Can I use the Risk Calculator for more than two options?

No, the tool is designed to compare exactly two options at a time. You would need to run separate calculations for each pair of choices you want to evaluate.

What happens if I am not sure about the probability values?

The calculator requires you to input numerical probabilities and consequence severities. If you are uncertain, you may want to research historical data or use your best estimate based on available information to get the most meaningful result.

Does the tool consider the cost of the options themselves?

The Risk Calculator focuses on the probability of failure and the severity of consequences. It does not factor in the monetary cost or effort required to implement each option.

Is the result a percentage or a score?

The output indicates which of the two entered options has the lower overall risk based on the inputs provided. The specific format of the result may vary, but it is designed to show a clear comparative assessment rather than a single numerical score.

About this tool

What Risk Calculator does

The Risk Calculator helps users compare two options by evaluating the probability of failure and the severity of potential consequences. It processes these inputs to determine which choice presents a statistically lower overall level of risk, supporting decisions in areas like project planning or investment choices. The result is a clear comparative risk profile that quantifies the trade-offs between the alternatives. Omni Calculator’s version stands out for its straightforward side-by-side input layout and plain-language explanations of how each factor influences the final risk assessment. Unlike more complex statistical software, it requires no prior knowledge of probability theory, making the calculation accessible to anyone needing to weigh options quickly and objectively.
