Lowest-Cost ETFs Available

Expense ratios have declined dramatically industry-wide, with several major providers now offering broad index ETFs at 0.03% or lower โ€” a meaningful factor in long-term returns.

Why Expense Ratios Matter So Much

Fees compound over time just like returns do โ€” a seemingly small difference between a 0.03% and 0.50% expense ratio can amount to tens of thousands of dollars over several decades on a substantial portfolio.

Low Cost Doesn't Mean Lower Quality

Broad index funds' low costs stem from passive management (simply tracking an index) rather than any compromise in underlying holdings quality โ€” these are widely-held, mainstream funds, not a discount alternative.

Common Mistakes

Focusing only on expense ratio without confirming the fund tracks an appropriately diversified index for your goals โ€” the cheapest fund isn't automatically the right fund if it doesn't match your intended exposure.

Frequently Asked Questions

How much does expense ratio actually matter?

Significantly over long time horizons โ€” even a 0.3-0.5% annual difference compounds to a meaningful amount over decades of investing, making low-cost funds a genuinely important factor.

Are the cheapest ETFs always the best choice?

Not automatically โ€” confirm the fund tracks an index that matches your actual investment goals before choosing based on cost alone, though among comparable funds, lower cost is generally preferable.
