As the new financial year FY 25 began yesterday, personal finance enthusiasts should take note that the benefits of schemes like the Public Provident Fund (PPF) and Sukanya Samriddhi Yojana (SSY) can be maximised by starting investment between April 1 and April. This is because the interest calculation of PPF and SSY will be done on the lowest balance in the account at the end of the fifth day of a month and the month's end. By investing Rs. 1.5 lakh within the initial five days of April in PPF or SSY, investors can make the entire 1.5 lakh earn interest for the entire financial year, thus maximising the effect of compounding. It is common knowledge that both these schemes work their magic through the power of compounding.
