SIP ₹10,000/Month for 20 Years: Real Returns

Most apps show you ₹99.91 L after 20 years on a ₹10,000/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%	₹76.57 L	₹52.57 L	₹23.87 L	₹21.79 L
12% (base)	₹99.91 L	₹75.91 L	₹31.15 L	₹28.13 L
15%	₹1.52 Cr	₹1.28 Cr	₹47.27 L	₹42.15 L

What You Invest vs What You Get

Over 20 years you contribute ₹24.00 L from your pocket (₹10,000 × 240 months). At a 12% CAGR that becomes ₹99.91 L, so compounding adds ₹75.91 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

₹99.91 L in 20 years is not ₹99.91 L of today's purchasing power. After 6% average inflation, it buys what about ₹31.15 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 ₹75.91 L of gains, a one-shot redemption implies roughly ₹9.71 L in LTCG tax, leaving about ₹90.21 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

₹10,000/month for 20 years. This is enough to build a useful base, but a flat contribution can fall behind as your income and goals grow. Link the SIP to a specific target and consider increasing it after a salary hike if expenses and emergency savings are already covered.

Step up the SIP. Raising ₹10,000 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.
