Which is the Best Date for SIP?

Over the last few years, Systematic Investment Plan (SIP) has become a household name.

Once the amount and time frame to invest has bee decided by the investor, the next important question comes to his mind – Which is the best date for SIP, so that he can maximize the returns.

Recently WhiteOak Capital Mutual Fund conducted a study, to address this important question.

Best SIP Date – Start of the month, End of the month – during Derivative expiry where markets tend to be volatile or Middle of the month? Or splitting the SIP amount into multiple dates?

An historical study of the BSE Sensex data since 1996 to 2025, suggests that there is no meaningful difference between the average returns of different dates.

To summarize, it doesn’t matter which date or frequency is selected, SIP which is started early, invested regularly and invested for long term takes you to the destination or your goal.
