PPF: The Public Provident Fund (PPF) is widely regarded as the top choice for long-term investments. The primary reason for this is its attractive interest rates combined with tax benefits. For the quarter of April to June 2026, PPF is providing an interest rate of 7.1%. However, many people are unaware that the timing of their PPF contributions can greatly affect their returns. If you haven’t set up a PPF account yet or if you invest on an annual basis, remember that making your deposit between April 1st and April 5th is the most advantageous. Discover how to maximize your benefits here.
How is interest calculated?
The interest on PPF is calculated based on the lowest balance recorded from the 5th of each month until the end of that month. This means that if you make a deposit by April 5th, your entire amount begins to earn interest from April itself.
Conversely, if you deposit funds on or after April 6th, you will not earn interest for that month, and your money will only start accruing interest the following month. This results in a loss of one month’s interest each year.
How much is the loss?
For instance, if you deposit Rs 1.5 lakh, making the deposit by April 5th allows you to earn a full year’s interest, which is around Rs 10, 650. However, if you deposit on April 6th, the interest you earn drops to about Rs 9, 763. This results in a difference of roughly Rs 800 to Rs 900 in the first year alone. While this difference may appear minor, it accumulates significantly over time.
A difference of millions in 15 years
If you consistently deposit Rs 1.5 lakh each year at the optimal time, that is, between April 1st and 5th, your total investment could grow from Rs 22.5 lakh to around Rs 40.68 lakh over 15 years. On the other hand, if you delay your investment each year, the same amount would only reach about Rs 37.8 lakh. This indicates that just the timing of your deposits could lead to a loss of approximately Rs 2.5 to Rs 3 lakh. Therefore, investing in PPF is not only essential, but ensuring you invest at the right time is equally important. Even a slight delay can diminish your returns.
