Confused About PF and ESI Calculations? Let's Discuss Employer Contributions!

Dear HR Experts,

On which amount (Basic or Gross) should PF and ESI be calculated? What should be the employer's contribution?

Thank you.

ESI is deducted on gross salary at 1.75% employee contribution and 4.75% employer contribution, totaling 6.5%.

EPF is deducted on basic salary plus DA at 12% employee contribution and 12% employer contribution, along with 0.85% for administration and 0.5% for EDLI, with an additional 0.01% for administration on EDLI, payable by the employer.
