Why Low-Cost ETFs Matter
Many investors focus primarily on returns while overlooking investment costs.
Even small fees can reduce portfolio performance over decades.
Example
Imagine two investors earning the same annual return.
- Investor A pays 0.03% annually
- Investor B pays 1.00% annually
After many years, Investor A may keep significantly more of their investment gains simply because of lower fees.
This is why low-cost ETFs remain attractive for long-term investors.
What Is an Expense Ratio?
The expense ratio represents the annual fee charged by an ETF.
For example:
- 0.03% expense ratio = $3 annually per $10,000 invested
- 1.00% expense ratio = $100 annually per $10,000 invested
Lower expense ratios generally allow investors to retain more of their returns.

Reduced costs help maximize long-term returns.
Simplicity
ETFs provide broad market exposure through a single investment.
Long-Term Growth
