You invest ₹50,00,000; compounding adds ₹2,23,67,829

You invest ₹50.00 L upfront. At a 12% CAGR over 15 years, that becomes ₹2.74 Cr, so compounding adds ₹2.24 Cr 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.

₹2,73,67,829 in 15 years buys what ₹1,14,19,639 buys today

₹2.74 Cr in 15 years is not ₹2.74 Cr of today's purchasing power. After 6% average inflation, it buys what about ₹1.14 Cr 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: ₹28,91,568 LTCG on ₹2,23,67,829 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 ₹2.24 Cr of gains, a one-shot redemption implies roughly ₹28.92 L in LTCG tax, leaving about ₹2.45 Cr. 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.
