What You Invest vs What You Get

₹20 Lakh for 15 years. A retirement horizon can support growth assets when they fit your capacity for loss, but the calculator's return is still a projection. Diversify rather than depending on one holding, and reduce or rebalance risk as the date for withdrawals approaches.

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 Number Apps Don't Show: Real Value

₹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.

Tax on Your Gains (LTCG)

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 (Income Tax Act 2025). On ₹89.47 L of gains, a one-shot redemption implies roughly ₹11.47 L in LTCG tax, leaving about ₹98.00 L.
