Variable DA is subject to change based on fluctuations in the consumer price index. The base index will vary depending on the industry and the agreement reached by the respective state's minimum wages committee. VDA will be calculated based on each increase in the consumer price index from the fixed base. Thus, referencing the CPI is essential for monthly VDA payments. Typically, VDA is a component of determining the minimum wage. In a specific industry (such as plywood, coir, or leather sector), all employees will receive the same VDA regardless of their basic salary.
On the other hand, Fixed DA is a set percentage of the basic salary. Therefore, a higher basic salary will result in a higher FDA. Fixed DA may not remain constant for an extended period. It can be adjusted periodically in line with CPI changes, though not frequently. The FDA amount will vary based on the individual's basic salary.
