The calculator uses the Expense Ratio formula:
Where:
Explanation: The formula calculates what percentage of the fund's assets are used to cover annual operating expenses. A lower expense ratio is generally better for investors.
Details: Expense ratio is a critical metric for investors to evaluate fund efficiency and cost-effectiveness. Lower expense ratios can significantly impact long-term investment returns due to compounding effects.
Tips: Enter total annual expenses and assets under management in USD. Both values must be positive numbers. The calculator will compute the expense ratio as a percentage.
Q1: What is considered a good expense ratio?
A: For index funds, ratios below 0.20% are excellent. For actively managed funds, ratios below 1.00% are generally considered reasonable.
Q2: How does expense ratio affect returns?

Q3: Are there different types of expense ratios?
A: Yes, common types include gross expense ratio (total costs) and net expense ratio (costs after fee waivers or reimbursements).
Q4: What expenses are included in the ratio?
