Prudential calculation is a term used to describe the process of assessing RISK in order to make a decision. It involves taking into account all potential risks and rewards associated with a particular action, and then making a decision based on the most prudent course of action. The term RISK, which is a four-letter word, is often used to describe this process. Prudential calculation is an important part of many business decisions, as it helps to ensure that the decision-maker is making the best possible decision for the company or organization.
