How to use this SIP calculator
Investing ₹15,000 every month through a SIP for 15 years at an assumed 12% annual return could grow to roughly ₹71,38,971. Of that, ₹27,00,000 is your own contribution and about ₹44,38,971 is estimated compounding growth.
The longer you stay invested, the larger the share that comes from growth rather than your deposits — which is the core advantage of starting a ₹15,000 SIP early.
What ₹15,000 a month becomes over time
Holding the monthly investment at ₹15,000 and the assumed return at 12%, the projected corpus grows sharply with the investment period:
In 10 years it could grow to about ₹33,60,538 (you invest ₹18,00,000 and the estimated gain is ₹15,60,538).
In 15 years it could grow to about ₹71,38,971 (you invest ₹27,00,000 and the estimated gain is ₹44,38,971).
In 20 years it could grow to about ₹1,37,97,860 (you invest ₹36,00,000 and the estimated gain is ₹1,01,97,860).
In 25 years it could grow to about ₹2,55,33,099 (you invest ₹45,00,000 and the estimated gain is ₹2,10,33,099).
Why the return assumption matters
These figures use a steady 12% return for illustration, but real equity returns fluctuate year to year. Treat the result as a planning range, not a guarantee, and test a lower return to see your downside.
Fund expense ratios and long-term capital-gains tax on equity gains above the annual exemption will also reduce the final amount you receive.
Making your ₹15,000 SIP work harder
Stepping up your SIP each year as your income grows usually builds a far larger corpus than chasing a higher return on a flat ₹15,000.
Link the SIP to a specific goal and stay invested through market dips — the automatic rupee-cost averaging of a monthly SIP works best over full market cycles.
