PF and EPF are the same things. 12% of the amount is being deducted from the employee's salary, and the same amount is contributed by the employer. However, the rule has changed post COVID-19. The employer's contribution amount is now 10% of the gross salary, deposited into the PF account every month.
If you want to know the difference between PPF and EPF:
PPF is a public provident fund that can be opened by any Indian citizen in a post office, government bank, or some private banks like ICICI Bank, HDFC, Axis, etc.
For PPF, the minimum compulsory contribution per year is Rs. 500, and the maximum amount one can deposit is Rs. 1.5 lakh per annum. The interest rates are declared quarterly. PPF has a lock-in period of 15 years, but after seven years, partial withdrawals are allowed.
EPF is mandatory, while PPF is voluntary.
