You invest ₹10,00,000; compounding adds ₹21,05,848

You invest ₹10.00 L upfront. At a 12% CAGR over 10 years, that becomes ₹31.06 L, so compounding adds ₹21.06 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.

₹31,05,848 in 10 years buys what ₹17,34,289 buys today

₹31.06 L in 10 years is not ₹31.06 L of today's purchasing power. After 6% average inflation, it buys what about ₹17.34 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: ₹2,57,510 LTCG on ₹21,05,848 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 ₹21.06 L of gains, a one-shot redemption implies roughly ₹2.58 L in LTCG tax, leaving about ₹28.48 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.
