About Wealth Creation Engineering
Use compound mathematics and consistent investment discipline to engineer your path to financial independence.
The Math Behind Becoming a Crorepati
The path to ₹1 Crore is straightforward mathematically. The compound growth formula — combining a lumpsum and monthly SIP — allows precise calculation of your target date. The most powerful variable is time: starting 5 years earlier can reduce the required monthly investment by nearly half. Use the what-if table to see how your Crorepati date changes across different return scenarios.
Why Your Crorepati Date Matters
Having a specific target date transforms an abstract goal into a concrete milestone. Research in behavioral finance shows that people with specific financial deadlines save 2–3x more than those with vague goals. Whether it's ₹1 Crore, ₹5 Crore, or retirement corpus — pinning the date on your calendar creates accountability and motivation to stay consistent with your SIP.
- Start Early: Time is the most powerful factor in compounding.
- Stay Consistent: Missing even 2–3 monthly SIPs can delay your date by months.
- Step Up Annually: A 10% annual SIP increase can advance your Crorepati date by years.

How long does it take to become a Crorepati in India?
It depends on your current savings, monthly SIP, and expected return. With ₹2L savings and ₹10K/month SIP at 12% returns, you'd reach ₹1 Crore in approximately 15–16 years. Higher SIP amounts or earlier starts can significantly reduce this timeline.
What return rate should I assume?
Equity mutual funds in India have historically delivered 12–15% CAGR over 10+ year horizons. For planning purposes, 10–12% is a conservative but realistic assumption. The calculator allows you to test different scenarios.
What is binary search used for in this calculator?
The calculator uses binary search to solve for the number of months needed to reach your target, since the compound growth equation cannot be directly inverted for time. This gives an accurate answer in milliseconds.
