wages for esi contribution
The ESI calculation for the employerâs contribution would be calculated as: 9000*(4.75/100) = 428. Note: Employerâs contribution is 4.75 percent. In case the salary goes above Rs 15,000 per month during the contribution period, the ESI would be calculated on the higher salary. For example, if the salary of an employee is raised to Rs 17,000 per month during the ESI contribution period, then the ESI would be calculated on Rs 17,000 instead of Rs 15,000. source.
