Chartered Accountant Nitin Kaushik emphasizes the importance of managing increased income wisely to avoid lifestyle creep, which can undermine long-term wealth. He highlights that many individuals fail to adjust their investments in line with salary increases, leading to stagnation in wealth accumulation. Kaushik presents a compelling case for adjusting Systematic Investment Plans (SIPs) annually by 10%. For instance, a fixed monthly SIP of ₹10,000 can grow to approximately ₹23.2 lakh over ten years at a 12% return. However, if investors increase their contributions by 10% each year, the total could rise to nearly ₹33.7 lakh, illustrating the significant impact of small, consistent changes. Kaushik advocates for redirecting a portion of salary increases into investments rather than allowing them to be absorbed by lifestyle upgrades, reinforcing the idea that wealth creation is driven by disciplined habits over time.
