13.61% is not the administrative charges.
Administrative charge is 1.10%
There is something called EDLI (Employee deposit linked insurance)
EDLI This is an insurance scheme to provide life insurance benefits to the employees of the establishments covered by the EPF & MP Act, 1952
1. On the death of an employment while in service a lump sum insurance amount is payable to his nominee or family members.
2. The insurance amount is equal to the average balance in the account of the deceased employee in the Provident Fund during a period of 12 months immediately preceding his death. In case the average balance exceeds Rs.50,000/- the insurance amount payable is Rs. 50,000/- plus 40% of the amount in excess of Rs. 50,000/- subject to a ceiling of Rs. 1,00,000/-. As per the 18th june, 2010 amendment
So for this EDLI Employer will contribute 0.5% on Basic + D.A and its administrative charge is 0.01 % on Basic + D.A
So
EPF (employer contribution) - 12%
Administrative charge for EPF - 1.10%
EDLI - 0.5%
Administrative charge on EDLI - 0.01%
TOTAL - 13.61%
And if you add employee’s contribution of 12 % it will be 25.61%
Contribution for Administrative charge will be from employer side
dont confuse with 6500 that is the ceiling, if you are getting more than 6500 as your basic and DA you can contribute 780 i.e 12 % of 6500 which is the minimum amount or you can contribute 12% on what you get (Basic + D.A)
