A ₹20,000/month SIP at 12% compounds to ₹1,99,82,958 in 20 years. After 6% inflation, that buys what ₹62,30,781 buys today. Adjust the rate, amount, and years in the calculator to test your own scenario.

Return Rate	Maturity	Wealth Gained	Real Value (6% inflation)	After-Tax Real Value
10%	₹1.53 Cr	₹1.05 Cr	₹47.75 L	₹43.54 L
12% (base)	₹2.00 Cr	₹1.52 Cr	₹62.31 L	₹56.20 L
15%	₹3.03 Cr	₹2.55 Cr	₹94.54 L	₹84.24 L

You invest ₹48,00,000; compounding adds ₹1,51,82,958

Over 20 years you contribute ₹48,00,000 from your pocket (₹20,000 × 240 months). At a 12% CAGR that becomes ₹1,99,82,958, so compounding adds ₹1,51,82,958 on top of what you put in. The longer you stay invested, the larger this gains-to-contribution ratio becomes; most of it lands in the later years.

₹1,99,82,958 in 20 years buys what ₹62,30,781 buys today

₹1,99,82,958 in 20 years is not ₹1,99,82,958 of today's purchasing power. After 6% average inflation, it buys what about ₹62,30,781 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: ₹19,57,535 LTCG on ₹1,51,82,958 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 ₹1,51,82,958 of gains, a one-shot redemption implies roughly ₹19,57,535 in LTCG tax, leaving about ₹1,80,25,423. Redeeming in tranches across financial years uses the ₹1.25 lakh exemption each year and can reduce that figure materially.

Each part of the portfolio needs a job

At this size the portfolio should carry separate jobs: retirement, a child's education, a dated goal. Review each target once a year and raise the contribution after a salary increase, once expenses and emergency savings are covered.

Step up, stay invested, cut costs, redeem in tranches

Step up the SIP: raising ₹20,000 by 10% a year as income grows beats the flat amount over 20 years.
Stay the full tenure: the biggest compounding happens in the later years; stopping early forfeits most of the gains.
Keep costs low: a direct-plan Nifty 50 index fund (0.1–0.2% expense ratio) preserves more of the 12% than a high-cost regular plan.
Redeem in tranches: spreading withdrawals across financial years uses the ₹1.25 lakh LTCG exemption repeatedly.
