Confused About My PF Balance SMS: Why Doesn't It Match My Calculations?

I received an SMS regarding my PF balance. The EE amount is 1768, and the ER amount is 541. However, this is for a period of 4 months. After that, my company transferred me to another company. My PF deduction per month from my salary is 500. Based on my calculations, my balance should be at least 4000, but I can't understand what the SMS means.

Dear Payal, Your EPF contribution will be divided into EE and ER. EE is the employee's contribution, the amount that is deducted from your salary. The other is ER, i.e., the employer's contribution. 8.33% out of 12% of the ER amount will fall under the pension fund, which is not displayed. Only 3.67% out of 12% of ER will be displayed. If you withdraw your PF amount before 10 years, you can withdraw EE and ER along with the amount that has fallen under the pension fund. If you continue the same account for more than 10 years, then automatically your pension account will be activated, and you can enjoy the benefits under the pension scheme.

As of now, your PF amount in your account is 1768 + 541 (3.67% of EE) + 1228 (8.33% of EE) = 3537 Rs approximately.
