Salary is a fixed amount of money paid to a worker for a particular work done usually on monthly or annual basis. When an employee is seeking employment, he's doing that majorly because he wants to work and at the same time get paid. CTC and Gross Salary talk about different types of ways the salary of an employee can be measured. CTC is the short form of Cost to Company. It simply means the total amount of money which an employee is going to receive from the employer in a year.
This also includes some additional benefits like bonuses apart from the real salary. It also includes all the money for different types of bills to be paid by the employees. Gross Salary, on the other hand, is the complete salary of an employee before any deduction will be made on it. It can also be seen as the amount of money an employee will be receiving as salary on monthly basis.
