Wherever the Minimum Wages as Applicable, there should not be split in Basic and DA in terms of percentile Calculation. It is only an assumption the Basic and DA shall be on percentage basis. No labour legislation recommends to have Basic and DA on percentage basis. At the same time, the social security benefits like EPF, Gratutity and bonus computations are based on the "Basic and DA" Wages.
If the employer prefers to contribute to EPF more than the cap limit (15,000), then we have to think of percentile based Basic and DA in other case it becomes meaningless.
