Public Provident Fund - PPF Partial Withdrawal Rule
you can make one withdrawal per year starting from your seventh year. The first withdrawal can be done after the expiry of 5 full financial years from the end of the year in which your initial subscription was made. The amount of withdrawal will be limited to 50% of the balance at credit at the end of the fourth year immediately preceding the year in which the amount is to be withdrawn, or the balance at the end of the preceding year, whichever is lower, as per the PPF rulebook. Thereafter, you can make one withdrawal per year. The withdrawal amounts are not repayable.
