The 15x15x15 SIP formula is not just a financial rule — it’s a mindset shift. It tells you that with patience, consistency, and smart planning, even an average person can become a crorepati (millionaire). You don’t need to chase hot stocks or time the market. Just pick a good mutual fund, set up a Rs 15,000 SIP, and let time and compounding do their job.
What is the 15x15x15 Rule in Mutual Funds?
The 15x15x15 rule is a simple investment formula that helps you understand the power of Systematic Investment Plans (SIP) in mutual funds:
- Invest Rs 15,000 per month
- For 15 years
- At an average annual return of 15%
By the end of 15 years, your investment can grow into a whopping Rs 1 crore. This is possible because of compound interest – where your earnings also earn interest, and the cycle keeps growing like a snowball over time.

How Does It Work? Let’s See an Example
Say you invest Rs 15,000 every month into a mutual fund SIP.
- In one year, you invest Rs 1.8 lakh.
- Over 15 years, the total money you put in is Rs 27 lakh.
- If the fund gives a 15% annual return (compounded), your money grows to around Rs 1 crore.
You didn’t need to double your income or win a lottery. Just regular investing and letting your money grow.
Why 15% Return? Is It Realistic?
Yes, 15% annual return might sound high, but it’s not unrealistic. Historically, equity mutual funds have given this kind of return over long durations. According to Value Research and AMFI, many large-cap and flexi-cap funds have delivered 12–18% CAGR (Compounded Annual Growth Rate) in the past 10-15 years.
Note: Returns are not guaranteed. Mutual fund returns are subject to market risks. Always check the past performance and scheme objectives before investing.

4. Ideal for Long-Term Goals
Perfect for goals like buying a home, children’s education, or building retirement corpus.

How to Start SIP with the 15x15x15 Strategy
Step 1: Choose a Reliable Mutual Fund Platform
You can invest through apps like Groww, Zerodha Coin, Paytm Money, Kuvera, or directly from AMC websites like SBI Mutual Fund, ICICI Prudential, HDFC, etc.
Step 2: Complete KYC
Online KYC is quick and paperless. You need PAN, Aadhaar, bank details, and a selfie.

For long-term wealth creation, opt for equity mutual funds (large-cap, flexi-cap, ELSS).
Step 4: Set Monthly SIP of Rs 15,000
You can automate it using auto-debit/UPI mandate.
Step 5: Track Your Investment Annually
Use platforms to check how your SIP is performing and rebalance if needed.
Bonus: What if You Continue Beyond 15 Years?
Let’s say you continue your Rs 15,000 SIP for 20 or 25 years:
- In 20 years: You can get over Rs 2.6 crore
- In 25 years: Your corpus may cross Rs 6.3 crore
That’s the true power of compounding. The longer you stay invested, the more exponential the growth becomes.
What If You Can’t Invest Rs 15,000 Per Month?
No problem! Start with what you can afford. Even a Rs 5,000 SIP for 15 years at 15% return gives you over Rs 35 lakh. The key is consistency. As your income increases, increase your SIP amount too (called SIP step-up).
