Dear All,
The terms Basic and CTC need not be interrelated at all. The Basic salary is fixed by the employer at his own free will. While fixing the basic, one needs to ensure that the company follows the Minimum wages for the category of employment only. The Minimum Wages Act, which is amended from time to time for various industries, forms the guideline for fixing Basic and DA. If you pay above the act, then there is no need to link it either with the Gross Wages or CTC. However, some companies follow this pattern, but it is not mandatory or statutory.
Trust the matter is clear.
