Is a Rs 10k monthly SIP for 30yr really enough to build a Rs 3Cr retirement corpus?

28M here. I keep seeing posts saying a Rs 10k SIP for 30yr at 12% will make me richer than Warren Buffett with a Rs 3Cr corpus.

I just started my career and this sounds like a great set-and-forget plan. But is this Rs 3Cr actually going to be enough for a comfortable retirement when I am 58?

The Rs 3Cr nominal figure you see on paper ignores the severe gravitational pulls that will drag your actual portfolio value down over the next 30yr. First, you have to account for mutual fund commissions and expense ratios. Even a conservative 1% commission over the lifespan of your investment will immediately drop your Rs 3Cr corpus to roughly Rs 2.5Cr.

Then comes the silent wealth destroyer which is inflation. While official CPI numbers might look tame, the real inflation rate for discretionary spending like healthcare, rent, and private education is much higher. If we assume a realistic lifestyle inflation rate of 6% to 9% for the Indian middle class, the real buying power of that Rs 2.5Cr plummets.

Adjusted for 9% inflation, the real value of your returns drops to just Rs 44L to Rs 45L in today's money. Finally, you must pay taxes on your returns. The LTCG tax on equities was recently hiked to 12.5%.

After adjusting for the Rs 1.25L annual exemption and paying the tax, your final take-home value shrinks even further. There is also no guarantee the government won't raise this tax to 15% or higher in the next decade.

The reality is that after deducting commissions, taxes, and inflation, your Rs 36L investment over 30yr will realistically yield a purchasing power equivalent to just Rs 45L to Rs 75L today. To fix this, you need to target a higher growth rate.
