How to Interpret
Lower is better. Even a 0.5% difference compounds to 10β15% over 20 years. US index funds (Vanguard, Fidelity, Schwab) charge 0.03β0.10%, active funds 0.5β1.0%. International markets like India: index funds 0.10β0.30%, active equity funds 0.5β2.5%.
Typical Ranges
US index funds: 0.03β0.10% (some zero-fee). India index funds: 0.05β0.30%. Active equity (both markets): 0.5β1.5%. Above 1.5% (US) or 2% (India) is expensive.
