| 50+ years | 30-50% | 50-70% | Capital protection, income generation |
Advanced Financial Planning Concepts
1. The Power of Compound Interest
Einstein called compound interest the eighth wonder of the world. Here's why:
Example: The Tale of Two Investors
Early Bird (Age 25-35)
- Invests ₹5,000/month for 10 years
- Total investment: ₹6 lakhs
- Stops investing at 35, lets it grow
- Value at 60: ₹1.48 crores
Late Starter (Age 35-60)
- Invests ₹5,000/month for 25 years
- Total investment: ₹15 lakhs
- Invests 2.5x more money
- Value at 60: ₹1.32 crores
Result: Early Bird accumulates more wealth despite investing less money!
2. Dollar Cost Averaging (SIP) vs Lump Sum
Market timing is nearly impossible. SIPs help you benefit from market volatility through rupee cost averaging:
- Market High: You buy fewer units
- Market Low: You buy more units
- Result: Your average cost is smoothed out over time
