Is 15% Return Realistic? Historical Data Analysis

- HDFC Top 100 Fund: 12.8%
- ICICI Pru Bluechip: 13.1%
- SBI Bluechip Fund: 11.9%
Verdict: 15% is optimistic for large caps. 12–13% is more realistic.
Flexi Cap / Multi Cap Funds
Average CAGR: 14.6%
- Parag Parikh Flexi Cap: 16.2%
- HDFC Prudence: 13.8%
- Kotak Flexi Cap: 14.1%

Mid Cap Funds
Average CAGR: 15.4%
- Axis Mid Cap: 16.7%
- Canara Robeco Mid Cap: 15.2%
- Nippon India Growth: 14.9%

Frequently Asked Questions (FAQs)
Is the 15x15x15 rule accurate?
It’s a simplified guideline. At 15% CAGR, ₹15,000/month for 15 years yields ₹1.13 crore. However, 15% returns are aggressive—12% is more realistic for diversified portfolios.
What if I can only invest ₹5,000/month?
You can still reach ₹1 crore by either extending the duration to 25+ years or increasing returns through smart asset allocation. Alternatively, use a step-up SIP to grow contributions over time.
Which funds should I choose for 15% returns?
Consider a mix of flexi-cap and mid-cap funds with a 10-year+ track record. Examples: Parag Parikh Flexi Cap, Axis Mid Cap, and HDFC Mid-Cap Opportunities. Always check expense ratio and portfolio concentration.
Are SIPs safe during market crashes?
Yes. SIPs use rupee cost averaging—buying more units when prices fall. This reduces average cost and enhances long-term returns. Staying invested through downturns is key.
Final Verdict: Should You Follow the 15x15x15 Rule?
The 15x15x15 SIP strategy is a powerful behavioral tool that encourages disciplined investing. While 15% returns aren’t guaranteed, the core message—consistent investing leads to wealth creation—is rock-solid.
✅ Do: Use it as motivation to start investing early and stay consistent.
