Understanding the 15 15 15 Rule
The 15 15 15 rule suggests that if you invest ₹15,000 every month for 15 years in a mutual fund that offers 15% annual returns, you can accumulate over ₹1 crore. Let’s break it down:
- Monthly SIP: ₹15,000
- Investment Tenure: 15 years
- Expected Returns: 15% annually
At the end of 15 years, your corpus will be approximately ₹1,00,27,601. But here's where it gets exciting. If you continue this investment for another 15 years with the same return rate, your corpus can grow to ₹10.38 crore. That’s the real power of compounding.

The Power of Compounding in Mutual Funds
Compounding means earning returns not just on your principal but also on the returns you’ve already earned. It creates a snowball effect the longer you stay invested, the more your wealth grows.
For instance, by continuing your ₹15,000 SIP beyond 15 years:
- The first ₹1 crore grows without additional effort.
- With just ₹27 lakh of additional investment over the next 15 years, your wealth could multiply 10x to over ₹10 crore.
This is why starting early, staying consistent, and letting time do the magic is critical in mutual fund investing.

How Does Compounding Actually Work?
Let’s look at a simple example of how the power of compounding works. Imagine two friends, X and Y:
- Y chooses a safe investment offering 7% interest.
- X chooses equity mutual funds with a long-term return potential of 15%.
Both invest ₹10,000/month for 10 years. While Y earns steady but modest returns, X faces market ups and downs, and sometimes his portfolio even falls. But over time, thanks to market recovery and growth, X’s investments outperform Y's significantly.
After 10 years:
- Y’s portfolio: ₹39.6 lakh (7% return)
- X’s portfolio: ₹1.13 crore (15% return)
Despite volatility, X ends up with nearly three times more than Y, all because of patience, discipline, and compounding.
Key Takeaways from the 15*15*15 Rule
- Start Early: The earlier you begin, the more time compounding has to work its magic.
- Be Consistent: Even in market downturns, stick to your SIP investments because it will help you in the long run.
- Think Long-Term: Wealth creation is a marathon, not a sprint.
- Choose Smartly: Pick mutual funds with strong track records and low expense ratios.
- Avoid Panic: Markets fluctuate, but long-term trends typically favour patient investors.
Is the 15*15*15 Rule Right for You?
Absolutely, if you're committed to long-term wealth building. The 15*15*15 rule in mutual funds shows that you don’t need to be rich to become wealthy. All you need is ₹15,000 per month, patience for 15 years, and a disciplined approach to achieve 15% returns. While returns aren’t guaranteed, equity mutual funds have historically delivered strong long-term performance.
Remember: “Paisa paise ko kheechta hai” money attracts more money when invested wisely. Be like Investor X: consistent, focused, and future-ready.
