Mutual Fund Wealth Secret: ₹10,000 will become ₹2 crore in a month! You just have to press this ‘secret button’ in SIP; This powerful calculation of compounding will surprise you


Most salaried people and investors start a fixed SIP of ₹5,000 or ₹10,000 every month and keep the same amount running for years. While even a simple SIP creates wealth in the long run, it has one major drawback—your income and salary grow by 8% to 12% every year, but your investments remain the same!

When setting up a SIP on mutual fund platforms (like Groww, Zerodha, Kuvera or CAMS) there is an option—’Step-up SIP’ or ‘Top-up SIP’. This is the same ‘secret button’, once activated, your monthly installment automatically increases every year as per your wish (like 10% or ₹ 1,000). This small change takes your final fund straight from ₹1 crore to ₹2 crore in 15 to 20 years.

  1. Direct coordination with salary increment: Your salary increases every year. If you top up only a part of the increased money in SIP instead of spending it immediately, then your lifestyle is not affected and the savings automatically increase.

  2. Brahmastra to defeat inflation: A normal ₹10,000 will not have the same value after 15 years as it does today. Step-up SIP does not allow the purchasing power of your investments to fall with inflation.
