SIP ₹3,000/Month for 20 Years: Real Returns

Most apps show you ₹29.97 L after 20 years on a ₹3,000/month SIP and stop there. Here's the complete picture: nominal corpus, real (inflation-adjusted) value, post-tax outcome, and conservative-to-optimistic return scenarios.

Return Rate	Maturity	Wealth Gained	Real Value (6% inflation)	After-Tax Real Value
10%	₹22.97 L	₹15.77 L	₹7.16 L	₹6.57 L
12% (base)	₹29.97 L	₹22.77 L	₹9.35 L	₹8.47 L
15%	₹45.48 L	₹38.28 L	₹14.18 L	₹12.68 L

What You Invest vs What You Get

Over 20 years you contribute ₹7.20 L from your pocket (₹3,000 × 240 months). At a 12% CAGR that becomes ₹29.97 L, so compounding adds ₹22.77 L on top of what you put in. The longer you stay invested, the larger this gains-to-contribution ratio becomes.

The Number Apps Don't Show: Real Value

₹29.97 L in 20 years is not ₹29.97 L of today's purchasing power. After 6% average inflation, it buys what about ₹9.35 L buys today. That's still real growth: your money grows faster than prices, but the honest figure is the inflation-adjusted one, not the headline number.

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 ₹22.77 L of gains, a one-shot redemption implies roughly ₹2.80 L in LTCG tax, leaving about ₹27.18 L. Redeeming in tranches across financial years lets you use the ₹1.25 lakh exemption each year and can reduce this materially.

How to Improve This Outcome

₹3,000/month for 20 years. The main advantage at this stage is time. A small automatic contribution builds the investing habit while giving you experience with market rises and falls. If broad equity exposure suits your goal, time horizon, and risk tolerance, a low-cost index fund can keep the first portfolio simple.

Step up the SIP. Raising ₹3,000 by 10% every year as your income grows beats a flat amount by a wide margin 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.
