How to Build a ₹2 Crore Fund by Age 50: CA Explains the SIP Formula You Just Need to Follow
If you are planning to start a Systematic Investment Plan (SIP) or wondering whether increasing your existing SIP can really make a difference, this strategy may completely change the way you look at long-term investing. A simple ₹18,000 monthly Step-Up SIP, when managed with discipline and patience, can help you build a ₹2 crore corpus by the age of 50—without chasing risky returns.
Chartered Accountant Nitin Kaushik recently explained this calculation in detail, showing how consistency, time, and compounding can quietly create massive wealth over two decades.
Why Small SIPs Are Often Underestimated
Many investors believe that investing a few thousand rupees every month is pointless. As a result, they delay starting their SIP or abandon it within a few years if returns look unimpressive. However, experts emphasize that the real power of SIP lies in long-term discipline, not short-term gains.
According to Nitin Kaushik, the magic of SIP does not show clearly in the first two or three years. But when you stay invested for 15–20 years, compounding starts working aggressively, transforming modest monthly investments into a large retirement fund.
The Step-Up SIP Strategy Explained
A Step-Up SIP means increasing your SIP amount every year, usually in line with salary growth or inflation. This method allows investors to start small and gradually invest more without feeling financial pressure.
Here’s the strategy explained step by step:
-
Start with a monthly SIP of ₹18,000
-
Increase the SIP amount by 6% every year
-
Stay invested for 20 years
-
Assume a realistic annual return of 10%
With these parameters, the numbers look surprisingly powerful.
How ₹18,000 Becomes ₹2 Crore
Over a 20-year period, an investor following this plan would invest a total of around ₹79.45 lakh. Thanks to compounding, the returns alone would cross ₹1.20 crore, taking the total corpus to approximately ₹2.00 crore.
Investment Summary
-
Monthly SIP (starting): ₹18,000
-
Annual Step-Up: 6%
-
Expected Annual Return: 10%
-
Investment Period: 20 years
-
Total Investment: ₹79.45 lakh
-
Total Returns: ₹1.20 crore+
-
Final Corpus: ₹2.00 crore (approx.)
This calculation highlights a crucial point—wealth creation is more about time in the market than timing the market.
Can This Corpus Generate Monthly Income After Retirement?
Building a large fund is only half the goal. The real question is whether it can support you after retirement. According to the analysis, a ₹2 crore corpus can generate a stable monthly income if withdrawals are planned smartly.
If an investor withdraws 5% annually (about ₹80,000 per month) and the remaining corpus continues to earn around 6% annual returns, the fund can last comfortably for decades.
Over a 30-year retirement period:
-
Total withdrawals can reach ₹2.88 crore
-
Remaining corpus after 30 years may still be close to ₹3.97 crore
This shows that disciplined investing not only builds wealth but also ensures long-term financial security.
Why This Strategy Works
There are three core reasons why this SIP plan succeeds:
-
Early Start – The sooner you begin, the more time compounding gets to work
-
Annual Step-Up – Helps beat inflation and increases savings without stress
-
Long-Term Discipline – Staying invested matters more than chasing high returns
Even with a modest 10% annual return, this approach delivers strong results due to consistency.
Final Takeaway
You don’t need to invest huge amounts or take extreme risks to become financially independent. A well-planned Step-Up SIP, started early and followed patiently, can help you build a ₹2 crore fund by age 50 and generate a steady post-retirement income.
The key lesson is simple: start early, increase gradually, and stay invested for the long term. That’s where real wealth is created.
