In addition to the logic given by Rohit, the percentage of variable pay depends upon the company's philosophy, especially regarding incentives. If a company wants employees' motivation to achieve certain targets, goals, or expectations, a considerable portion of their CTC needs to be variable. Additionally, it needs to be weighed against market trends, the level of the employee, and the psychological comfort or surety expected from employees for a committed CTC.
Hence, as mentioned by the expert above, there is no "One Size Fits All" solution or "Manual" available for Variable Pay. Once implemented, you also need to review it regularly to arrive at the most effective variable pay policy for your organization, as the post-implementation scenario would provide you with feedback.
