When investing in mutual funds, it’s easy to focus on returns without considering the cost of managing your investment. Mutual funds charge an expense ratio, which is an annual fee expressed as a percentage of your investment. This fee covers management, administrative, and operational expenses.

Formula Used for Expense Ratio Calculation
1. Annual Expense Amount
Annual Expense = Investment Amount × (Expense Ratio ÷ 100)
2. Cumulative Expense Over Time
Total Expense = Investment Amount × (Expense Ratio ÷ 100) × Number of Years
3. Adjusted Investment Growth (Optional)
If considering compounding returns, adjust the investment for annual growth minus expense:
Adjusted Investment Value = P × (1 + r − ER)ⁿ
Where:
- P = Principal investment
- r = Expected annual return (as a decimal)
- ER = Expense ratio (as a decimal)
- n = Number of years
Step-by-Step Example
Example 1: Single-Year Investment
- Investment = $10,000
- Expense ratio = 0.75%
Step 1: Annual expense = 10,000 × 0.0075 = $75
✅ Result: Annual fee = $75
Example 2: Five-Year Investment with Compounding Consideration
- Investment = $20,000
- Expense ratio = 1%
- Expected annual return = 8%
- Duration = 5 years
Step 1: Adjusted annual growth = 8% − 1% = 7%
Step 2: Adjusted investment value after 5 years = 20,000 × (1 + 0.07)⁵ ≈ $28,051
Step 3: Total expense = 20,000 × 0.01 × 5 = $1,000
✅ Result: Net investment after 5 years ≈ $28,051, cost of fees = $1,000
