PPF investment calculation
Suppose you invest ₹ 1.5 lakh per year in PPF. Currently the interest rate is 7.1%. If you invest money between 1st and 5th April, you will earn Rs 10,6506 for the entire 12 months. If you deposit money on or after April 6, you will get interest only for 11 months, that is, you will get only ₹ 9,763. That means if there is a delay of just one day, there will be a loss of about ₹ 887 in the first year itself. Now imagine, in a long investment of 15 years, this small mistake will reduce your lakhs of rupees.
