The public provident fund (PPF) is a top choice when it comes to long-term financial planning. Launched by the Centre in 1986, it is a reliable, low-risk government backed savings scheme with consistent and guaranteed returns.

Among the safest investment options for tax planning and an effective wealth builder, you can open a PPF account at a post office or bank by submitting an application form, photo and stated KYC documents.

Public provident fund account for children

For children or minor applicants, a parent or guardian can open a joint PPF account which can be converted once the account holder turns 18 years old.

  • Withdrawals: Partial withdrawal is allowed after five years of opening an account only for specified reasons. Full withdrawal is allowed after the 15 years lock-in period ends.

How to maximise returns for your PPF investment?

Under PPF, interest is calculated on a monthly basis on the minimum balance between 5th and the end of the month. And, while interest is calculated on monthly basis, it is transferred to your account annually on 31 March. Thus, if you miss the deposit before 5 April, your money starts earning from the next month (i.e. May) and you miss out on one full month of interest.

Calculated as follows: For ₹1.50 lakh invested during the financial year interest of ₹887.5 per month is earned at the current interest rate of 7.1%. On an annual basis this is ₹10,650. So, investing after April 5 would lead to loss of one ₹887.5 installment from the total, giving you ₹9,762.5 on investment of ₹1.5 lakh, and so forth.

The impact is even bigger when you take into account the power of compounding: At 7.1% p.a. (assuming same rate for 15 years), investing ₹1.5 lakh by 5 April annually, over the full duration earns you an interest of ₹18.18 lakh. Missing the deadline even for one year, reduces your cumulative interest to ₹17.95 lakh (loss of ₹23,188).
