ESI Calculation - How is ESI Computed?

So, what is ESI in salary? ESI full form in salary is Employee State Insurance (ESI). It is a contributory fund that receives payments from both the employer and the employee, allowing Indian employees to participate in a self-funded healthcare insurance fund. The Employee State Insurance Corporation, a government entity, administers the plan controlled by the ESI Act of 1948. Employees' Social Insurance (ESI) is the world's biggest integrated need-based social insurance program. It safeguards employees in the case of unforeseen and unpleasant circumstances. The program includes both monetary and medical benefits.

ESI applies to all non-seasonal factories with ten or more employees. ESI is available to all enterprises protected by the Factory Act, as well as Shops and Establishments. This Act applies to units with ten or more employees or those that are located in scheme-implemented regions. Therefore, let's delve into the different aspects of ESI in salary.

Contribution of ESI in salary

The ESI scheme is a contributory scheme; therefore, all employees in the factories or establishments to which the Act applies must be insured in accordance with the Act's provisions. In the case of an employee, the contribution payable to the Corporation will be made up of the employer's contribution and the employee's contribution at a certain rate.

The tariffs are updated regularly. Currently, the ESI contribution salary limit is as follows -

  • The employee contribution rate is 0.75% of earnings (effective July 1, 2019)
  • The employer contribution rate is 3.25% of wages paid/payable for employees in each wage period.
  • Employees who earn a daily average income of up to Rs.137/- are free from contributing. Employers, on the other hand, will contribute their fair share in the case of these workers.

ESI calculation on salary 

The ESI calculation on salary is based on the wages earned. Employee contributions are now 0.75% of earnings paid/payable, while employer contributions are 3.25% of wages paid/payable.

We can understand it with an example - 

Consider Mr Harsh, who works at a factory and earns Rs. 10,000 per month.

The following will be the ESI in salary slip:

  • Employee contribution = 0.75 percent x 10,000 = 75
  • Employer contribution = 3.25 percent x 10,000 = 325

As a result, a total donation of Rs. 400 will be made. The employer is responsible for deducting and paying the contribution. Within 15 days after the end of the calendar month in which the deduction is made, the employer must deposit the money. Deposits can be made online or at authorised SBI approved banks or other designated branches.

Contribution Collection of ESI in salary

An employer is responsible for paying their contribution for each employee and deducting employee contributions from wages. They must make these contributions to the Corporation at the above-stated rates within 15 days of the last day of the calendar month in which the contributions are due. The Corporation has allowed selected State Bank of India and other institutions to accept payments on its behalf.
