A ₹10,000 SIP sounds like a disciplined, sensible start. But when the goal is ₹1 crore in 15 years, the math can feel like a reality check. That is where the idea of Step-Up SIP comes in.
Meet Mr Parth, an IT professional in his early 40s. He decides to start a SIP of ₹10,000 per month with a clear goal: building a ₹1 crore fund in the next 15 years.
To test the goal, he uses an SIP calculator with these assumptions:
Outcome after 15 years (₹10,000 SIP at 12% CAGR):
• Total value: ₹50,45,760
• Invested amount: ₹18,00,000
• Estimated returns: ₹32,45,760
This gap is not because the SIP is “bad”. It is because ₹10,000 stays ₹10,000 for 15 years, while the goal quietly grows in the background due to inflation, lifestyle expectations, and time.
A Step-Up SIP is exactly what it sounds like. Instead of investing the same amount every month forever, you increase your SIP contribution at a fixed rate every year.
So, the SIP does not remain stuck at ₹10,000. It rises gradually, usually in line with income growth.
In Parth’s case, everything remains the same:
Only one thing changes:
Here is the same SIP plan, but with Step-Up SIP applied.
Outcome after 15 years (Step Up SIP at 13% annually and 12% CAGR):
• Total value: ₹1,04,28,130
• Invested amount: ₹48,50,268
• Estimated returns: ₹55,77,862
So, the outcome crosses ₹1 crore not because returns magically improved, but because the contribution grew with time.
In a normal SIP, the invested amount for Parth over 15 years is:
₹10,000 × 12 × 15 = ₹18,00,000
In a Step-Up SIP, the invested amount rises because the SIP keeps increasing every year, leading to:
₹48,50,268 invested across 15 years
That extra invested capital plays a big role in creating a higher final value, even with the same 12% CAGR assumption.
Parth’s story highlights a practical lesson: ambition is good, but numbers decide the route. A ₹10,000 SIP for 15 years at 12% CAGR can build a meaningful corpus of around ₹50.45 lakh. A Step-Up SIP with a 13% annual increase can push the final number near ₹1 crore, simply by investing more over time while letting compounding do its work.
