You invest ₹20,00,000; compounding adds ₹89,47,132

You invest ₹20.00 L upfront. At a 12% CAGR over 15 years, that becomes ₹1.09 Cr, so compounding adds ₹89.47 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.

₹1,09,47,132 in 15 years buys what ₹45,67,856 buys today

₹1.09 Cr in 15 years is not ₹1.09 Cr of today's purchasing power. After 6% average inflation, it buys what about ₹45.68 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: ₹11,46,877 LTCG on ₹89,47,132 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 ₹89.47 L of gains, a one-shot redemption implies roughly ₹11.47 L in LTCG tax, leaving about ₹98.00 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.
