Spoiler alert: Longer time in the market trumps higher monthly contribution.
The Numbers That Make You Pause
-
₹15,000 per month for 20 years → corpus of ₹1.38 crores
-
₹20,000 per month for 15 years → corpus of ₹96 lakhs
The ₹15,000 SIP over 20 years actually yields ₹42 lakhs more than the larger SIP stretched over a shorter period — a whopping 44% greater outcome. This striking difference exemplifies the unrivaled power of compounding and time in the market.
Why Time Beats Amount
-
Compounding Magic: Even a modest monthly investment can grow massively if given enough time to compound.
-
Start Early, Reap Big: The longer your money stays invested, the greater the growth — regardless of incremental increases.
-
Patience is Key: The results visually— and numerically— show that investing longer offers more than investing more in a shorter time.
What Other SIP Insights Say
-
A modest SIP of ₹5,000 per month at an average 12% return:
-
20 years → approximately ₹33.99 lakhs
-
15 years → around ₹14.80 lakhs
-
-
With a higher assumed return (15%), ₹15,000 invested monthly for 20 years could grow to ₹2.27 crores
These numbers reinforce the same message: a longer investment horizon can dramatically amplify returns.
Key Takeaways for Investors
| Strategy | Benefit |
|---|---|
Start early, even with a smaller amount | Benefit from compounding over time |
Keep the SIP consistent | Regular investment beats sporadic heavy investments |
Be realistic about returns | Market-linked investments vary—expect around 10–12%, not always 15% |
| Avoid shortcuts | Viral formulas like "15-15-15 = ₹1 crore" can be misleading and don’t account for market volatility |
Final Word
If you're choosing between investing ₹15,000 monthly for 20 years or ₹20,000 monthly for 15 years, go with the longer timeline. A longer horizon doesn't just offer Security—it builds a significantly larger corpus. In finance, time is more powerful than the speed of investing more.
