ETF Expense Ratio Impact Calculator

How ETF Management Fees Eat Your Profits

When you invest in an ETF, you do not receive a bill for the management fees. Instead, the fund's **Total Expense Ratio (TER)** is deducted daily from the fund's Net Asset Value (NAV). If an ETF has a 0.50% TER, the fund value is reduced by 0.50%/365 every day.

The Compound Drag Explained

The real damage of fees is not just the cash paid to the fund manager. It is the **opportunity cost**. Every dollar deducted as a fee is a dollar that cannot compound in the stock market. Over 20 or 30 years, that lost compound growth makes a massive difference:

  • Cheap Index ETFs (0.05% - 0.20%): Usually track popular stock indices like the S&P 500 or MSCI World. They keep costs to a bare minimum, letting almost 100% of the market returns accrue to your portfolio.
  • Active Mutual Funds & Expensive ETFs (0.50% - 1.50%): Try to outperform the market but usually fail over long periods. A 1.0% fee might sound small, but over 30 years it can eat up **20% to 25% of your final nest egg**.

Example Impact Table

For a $100,000 starting portfolio growing at 8% gross over 30 years (without monthly deposits):

Scenario TER Final Balance Lost to Fees
Gross (Zero fees) 0.00% $1,006,265 $0
Low-cost Index ETF 0.07% $986,505 $19,760 (1.9%)
Active / High-fee Fund 0.75% $814,896 $191,369 (19.0%)
