What You Invest vs What You Get

₹10 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 ₹10.00 L upfront. At a 12% CAGR over 15 years, that becomes ₹54.74 L, so compounding adds ₹44.74 L on top of your investment.

The Number Apps Don't Show: Real Value

₹54.74 L in 15 years is not ₹54.74 L of today's purchasing power. After 6% average inflation, it buys what about ₹22.84 L buys today.
