Cheapest ETFs With Ultra-Low Expense Ratios and Fees

BNY Mellon made ETF history when it launched BKLC and BKAG — the first funds to carry a permanent expense ratio of zero without temporary waivers. That milestone underscored a broader industry trend: the relentless compression of ETF fees, where even a fraction of a basis point separates one fund from another.

An expense ratio is the annual cost of running a fund, expressed as a percentage of assets. You never pay it out of pocket — it’s deducted from the fund’s assets, which means it quietly reduces your returns over time. Because these costs compound just like returns, a seemingly small difference can translate into tens of thousands of dollars over decades.

Who leads on cost? The cheapest ETFs with ultra-low expense ratios tend to come from a handful of providers:

  • Vanguard: Founded in 1975 with a client-owned structure, Vanguard offers nearly two dozen ETFs at 0.03%. Its downward pressure on industry fees is widely known as The Vanguard Effect®.
  • iShares (BlackRock): The iShares Core S&P 500 ETF (IVV) tracks the S&P 500 at an expense ratio of 0.03%.
  • SPDR (State Street): SPAB provides broad U.S. investment-grade bond exposure — Treasurys, corporates, and mortgage-backed securities — at 0.03%.
  • JPMorgan: The BetaBuilders U.S. Equity ETF (BBUS) charges just 0.02%, tracking U.S. large and mid-cap equities via the Morningstar US Target Market Exposure Index.
  • BNY Mellon: BKLC (equity, 504 stocks) and BKAG (bonds, thousands of holdings) both carry a 0.00% expense ratio — permanently, not through temporary waivers.

A general rule applies: the more specialized a fund, the more it costs. Broad-market index ETFs are the cheapest, while sector-specific, leveraged, or inverse funds tend to charge significantly more. The same pattern holds on the bond side — aggregate bond ETFs are cheaper than those targeting niche areas like high-yield or emerging-market debt.
