You invest ₹20,00,000; compounding adds ₹42,11,696

You invest ₹20.00 L upfront. At a 12% CAGR over 10 years, that becomes ₹62.12 L, so compounding adds ₹42.12 L on top of your investment. The longer you stay invested, the larger this gains-to-contribution ratio becomes; most of it lands in the later years.

₹62,11,696 in 10 years buys what ₹34,68,579 buys today

₹62.12 L in 10 years is not ₹62.12 L of today's purchasing power. After 6% average inflation, it buys what about ₹34.69 L buys today. That is still real growth: your money grows faster than prices, but the honest figure is the inflation-adjusted one, not the headline number.

One-shot redemption: ₹5,31,270 LTCG on ₹42,11,696 of gains

Equity mutual fund units held over 12 months qualify for long-term capital gains tax: 12.5% on gains above the ₹1.25 lakh annual exemption. On ₹42.12 L of gains, a one-shot redemption implies roughly ₹5.31 L in LTCG tax, leaving about ₹56.80 L. Redeeming in tranches across financial years uses the ₹1.25 lakh exemption each year and can reduce that figure materially.

10+ years give the 12% projection time to compound

A single deposit over 10+ years compounds at the projected 12%, while 6% inflation and LTCG tax trim the headline figure. Diversify across holdings and reduce the risk as the withdrawal date approaches.
