Hi Mohammad,
ESI is contributed from both sides, by the Employee as well as the Employer. It is calculated based on the Gross salary per month, with a maximum ceiling of 10,000 Rs. per month. The contributions from both sides are as follows:
On the Employee's side - 1.75% of gross per month. So, if the gross salary of an employee is 8,000 per month, the ESI contribution would be 8,000 * 1.75% = 140 Rupees.
On the Employer's side - 4.75% of gross per month. The ESI contribution would be 8,000 * 4.75% = 380 Rupees.
The same contribution structure applies to PF, which is also contributed by both the Employee and the Employer. Both contribute 12% of the Basic salary. The ceiling for the basic salary is 6,500 Rs. This means that those receiving more than 6,500 Rs. as basic salary can be part of PF, but the deduction would be only 12% of their basic salary.
During payroll processing, the employer deducts the sum of ESI contribution and PF contribution from the gross total.
I hope this explanation clarifies things for you.

Amit Seth.
