The Math of Long-Term Performance
Compounding Differences
Final\ Value = Initial\ Investment \times (1 + Annual\ Return)^{10}$10,000 Invested in 2014:
- 8% return = $21,589
- 10% return = $25,937
- 12% return = $31,058
- 15% return = $40,456
The Fee Impact Decade
Wealth\ Drag = (1 - \frac{High\ Fee\ Fund}{Low\ Fee\ Fund})^{10}Example:
- Fund A: 0.05% expense ratio
- Fund B: 0.75% expense ratio
Drag = (1 - \frac{0.9975}{0.9995})^{10} = 7.2\%\ underperformance
