CTC means the financial cost to the company per employee. It covers all components. Many employers do consider in CTC,contribution to PF by employer, Gratuity, Bonus, cost of the housing provided by the company if HRA is not paid, leave encashment etc. Hence, based on these facts, you can work out CTC for any employee.

Thanks for the explanation Mr.Babu Alexander. But what is the special allowance amount.
See first need to find the Gratuity then PF then ESI after that only know the special allowance. Please help reverse calculation.
