Your question relates to financial planning for your son's future, specifically investing through SIP (Systematic Investment Plan) to accumulate ₹4 crore in 25 years.

To achieve ₹4 crore in 25 years, you need to consider factors like the expected rate of return and the SIP amount. Equity mutual funds are often recommended for long-term goals like this due to their potential for higher returns, typically averaging around 12-15% annually over the long term.

A rough example: If you assume a 12% annual return, a monthly SIP of around ₹15,000 to ₹18,000 could help you reach ₹4 crore in 25 years. This is illustrative and actual amounts may vary based on market performance.

It is best to choose diversified equity mutual funds or large-cap and multi-cap funds with consistent performance for your SIP. Consulting a financial advisor for personalized recommendations tailored to your risk profile and financial goals is advisable.
