SIP ₹1,000/Month for 20 Years: Calculator Scenario

20 years of ₹1,000/month at 12% ends at ₹9,99,148. Subtract 6% inflation a year and the real figure is ₹3,11,539. 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% ₹7.66 L ₹5.26 L ₹2.39 L ₹2.23 L
12% (base) ₹9.99 L ₹7.59 L ₹3.12 L ₹2.86 L
15% ₹15.16 L ₹12.76 L ₹4.73 L ₹4.26 L

You invest ₹2,40,000; compounding adds ₹7,59,148

Over 20 years you contribute ₹2,40,000 from your pocket (₹1,000 × 240 months). At a 12% CAGR that becomes ₹9,99,148, so compounding adds ₹7,59,148 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.

₹9,99,148 in 20 years buys what ₹3,11,539 buys today

₹9,99,148 in 20 years is not ₹9,99,148 of today's purchasing power. After 6% average inflation, it buys what about ₹3,11,539 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: ₹82,439 LTCG on ₹7,59,148 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 ₹7,59,148 of gains, a one-shot redemption implies roughly ₹82,439 in LTCG tax, leaving about ₹9,16,709. Redeeming in tranches across financial years uses the ₹1.25 lakh exemption each year and can reduce that figure materially.

Time is the main asset

At this stage the main asset is time: a small automatic contribution builds the habit while you watch markets rise and fall. If broad equity suits your horizon, a low-cost index fund keeps the first portfolio simple.

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

  • Step up the SIP: raising ₹1,000 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.

At 12% CAGR (Nifty 50 long-term average), a ₹1,000/month SIP for 20 years grows to ₹9.99 L. You invest ₹2.40 L and gain ₹7.59 L. In conservative (10%) and optimistic (15%) scenarios it becomes ₹7.66 L and ₹15.16 L respectively.
What is the real (inflation-adjusted) value of ₹1,000 SIP after 20 years?
The ₹9.99 L maturity has the purchasing power of about ₹3.12 L in today's money, after 6% average inflation. Nominal numbers always look bigger than what they can actually buy.
How much tax do I pay on a ₹1,000 SIP maturing in 20 years?
Equity mutual fund gains held over 12 months are taxed as LTCG at 12.5% above the ₹1.25 lakh annual exemption (Income Tax Act 2025). On total gains of ₹7.59 L, the indicative LTCG tax is ₹82,439, leaving roughly ₹9.17 L post-tax. Actual tax depends on how you redeem (staggered exits use the exemption each year).
Is ₹1,000/month SIP enough?
It depends on your goal. ₹1,000/month for 20 years builds ₹9.99 L at 12%. Increasing the SIP by 10% each year (step-up) as your salary grows can substantially raise the final corpus versus a flat amount.
