Expense Ratio = (Total Annual Operating Expenses ÷ Average Assets Under Management) × 100
Example
Suppose an ETF has:
- Total Annual Expenses: ₹5 Crore
- Average AUM: ₹2,000 Crore
Expense Ratio = (5 ÷ 2000) × 100 = 0.25%
That means investors pay ₹250 annually for every ₹1,00,000 invested, although the deduction happens daily through the ETF’s NAV.
