₹50 lakh Lumpsum Investment for 15 Years

Lumpsum or stagger it through an STP?

A lumpsum puts the entire ₹50 lakh to work immediately, which mathematically beats spreading it out in a rising market — and markets rise more often than they fall. The risk is timing: investing everything days before a 30% drawdown is painful even if the 15-year result eventually recovers.

The common middle path is a Systematic Transfer Plan: park the money in a liquid fund and move it into equity over 6-12 months. You give up a little expected return for a lot less regret risk.

What this actually earns after tax

Equity mutual fund gains held over a year are long-term capital gains, taxed at 12.5% beyond the ₹1.25 lakh annual exemption. On a gain of ₹2.24 crore, the tax would be roughly ₹27.80 lakh if redeemed in one go.

Redeeming across two financial years uses the exemption twice. That single piece of sequencing can save a meaningful amount at this size.

The inflation reality check

₹2.74 crore in 15 years buys what about ₹1.14 crore buys today. Against an FD, which would have produced ₹1.42 crore before tax and considerably less after, the equity route is still well ahead — but the gap narrows once you count tax and sequence risk.
