Gain formula

The Gain formula is a concept used in various fields, including finance and engineering, to measure the effectiveness of a process or system. Essentially, it expresses how much output is produced relative to input. In finance, for example, it measures profit against investment. Mathematically, it's often represented as Gain = (Output - Input) / Input. This helps to understand how much better or worse something performs compared to its initial state. A higher gain indicates a more successful or efficient outcome, while a lower or negative gain suggests that the process needs improvement.
