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.

| 5 year | ₹8.25 lakh | ₹9.82 lakh | + ₹1.57 lakh |

-
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.
-
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.
-
No pressure of huge amount at young age: If you can’t do a SIP of ₹30,000 a month straightaway today, no worries. Start with a comfortable amount like ₹10,000 and increase it over time as per your financial capacity.
