SIP ₹3,000/Month for 15 Years: Real Returns

Most apps show you ₹15.14 L after 15 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%	₹12.54 L	₹7.14 L	₹5.23 L	₹4.91 L
12% (base)	₹15.14 L	₹9.74 L	₹6.32 L	₹5.86 L
15%	₹20.31 L	₹14.91 L	₹8.47 L	₹7.73 L

What You Invest vs What You Get

Over 15 years you contribute ₹5.40 L from your pocket (₹3,000 × 180 months). At a 12% CAGR that becomes ₹15.14 L, so compounding adds ₹9.74 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

₹15.14 L in 15 years is not ₹15.14 L of today's purchasing power. After 6% average inflation, it buys what about ₹6.32 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 ₹9.74 L of gains, a one-shot redemption implies roughly ₹1.10 L in LTCG tax, leaving about ₹14.03 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 15 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 15 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.
