Provident Fund Calculating

Hi,
Please help me: I want to claim my PF from a Previous Employer, I only know that PF was deducted and I was employed for 14 months in 07/2004 - 08/2005 , My salary advice shows PF deduction, (various amounts)
How do I know if the Employer Contributed ?
How do I calculate the interest (to date) ?
Can I do a calculation with only this info ?
Please Help
Thanks In Advace

Hi,
1.Ask your PF A/c no from previous employer.
2.When you will get PF A/c no then you can view through EPFO portal balance and interest credited in your A/c.
