Dear Reena,
I have already explained the same. ESI is contributed from both sides: the Employee as well as the Employer. It is calculated based on the Gross salary per month, and the maximum ceiling is 10,000 Rs./Month. The contribution from both sides is as follows:
Employee Side - 1.75% of gross/month
So, if the gross of an employee is 8,000/month, then the ESI contribution would be 8,000 * 1.75% = 140 Rupees.
Employer Side - 4.75% of gross/month
ESI contribution would be 8,000 * 4.75% = 380 Rupees.
On the other hand, PF is also paid from both sides. Both the employer and the employee are required to pay 12% of the basic salary. Out of this 12% of the employer's contribution, 8.33% goes to the Pension fund, whereas the remaining 3.67% goes to the PF Fund itself.
Regards,
Amit Seth.
