No single fund can be called universally cheapest on the available figures: QQQM’s reported fee is one dated example, while the available iShares fee information is incomplete.
Start with what the ETF holds
The Nasdaq-100 is an index, not an investable fund. An ETF is one way to gain exposure to it; Nasdaq lists QQQ and QQQM among the ways investors can invest in the index (Nasdaq: Nasdaq-100). An ETF aims to deliver exposure to its benchmark, but it is a separate fund with its own expenses, trading costs, and implementation.
A supplement filed for QQQ and QQQM on April 30, 2026, describes the index as designed to include securities of 100 of the largest domestic and international non-financial companies listed on U.S. exchanges (SEC-filed QQQ/QQQM supplement). That is an index-design description, not a promise that an ETF holds exactly 100 securities at every moment.
Compare fund fees on the same basis
Check each candidate’s latest prospectus or official fund page for its gross expense ratio, net expense ratio, and any waiver or reimbursement. A waiver can make the currently charged net fee lower than the gross fee, but its terms and end date matter: compare the fee you would pay over your expected holding period, not just a headline figure.
#1 Best Overall
Invesco’s Q1 2026 product information reported a 0.15% total expense ratio for QQQM (Invesco QQQM product information). This is a dated figure; verify the current prospectus before investing or comparing it with another fund.
The iShares Nasdaq 100 ETF summary prospectus dated July 8, 2026, mentions a 0.02% fee waiver and/or expense reimbursement, but that figure is not the fund’s expense ratio. The available information does not establish its complete net fee or the waiver’s end date, so it cannot support a direct fee ranking against QQQM. Check the prospectus for the full gross and net expense ratios and waiver terms before comparing (iShares Nasdaq 100 ETF summary prospectus).
Estimate the costs of buying, holding, and selling
The expense ratio is only one part of ownership cost. Invesco identifies bid-ask spreads, trading commissions, and premiums or discounts to net asset value as additional factors (Invesco ETF cost information). A lower annual fee may not mean lower realized cost if you trade often or pay more to enter and exit.
- Bid-ask spread: The difference between the price available to buy and the price available to sell. It is a trading cost, and its size can vary; check live market data rather than assuming it is the same across funds.
- Commissions and account charges: Check your brokerage’s terms for the specific ETF and account. A commission-free trade does not eliminate the spread or other account costs.
- Premium or discount: An ETF’s market price can differ from its net asset value. Consider this alongside the spread when placing a trade.
For a long-term investor making few purchases, recurring fund expenses may deserve particular attention. For frequent traders, execution conditions can matter more. Compare the factors using your own account and trading pattern; current comparable spread data are not established here.

A fund’s return can differ from its index’s return because of expenses, transaction costs, securities it cannot obtain, or extraordinary circumstances. Invesco describes these potential sources of divergence in its fund information (Invesco QQQM product information).
When comparing funds, look at tracking difference—the gap between fund and benchmark returns—over the same dates and on a comparable basis. Confirm that each fund uses the same benchmark and compare like periods; a single short interval is not enough to establish a persistent advantage. Historical results do not guarantee future performance.
Understand the index rules and fund implementation
Index exposure depends on the rules used to select and maintain the index, as well as on how a fund implements those rules. Nasdaq says it implemented targeted Nasdaq-100 methodology updates on May 1, 2026, following a public consultation (Nasdaq methodology update). The QQQ/QQQM supplement also states that the changes take effect on that date (SEC-filed QQQ/QQQM supplement).
For a current comparison, check that you understand each fund’s stated benchmark and review its prospectus for implementation details. The methodology update is relevant context for how the index is maintained; it does not by itself predict returns or establish that one ETF will perform better.
Do these 3 things before closing this tab:

Share price can affect how conveniently you invest a fixed amount, especially if your account does not support fractional ETF shares. It does not indicate whether a fund is cheap relative to its holdings or whether it has a low total cost. Check whether your brokerage permits fractional purchases and compare the minimum practical purchase size with your budget.
A practical comparison checklist
- Confirm the benchmark. Verify that each ETF tracks the Nasdaq-100 and check its prospectus for the index and implementation details.
- Record current fees. Use official, current fund documents to note gross and net expense ratios. Record waiver or reimbursement terms and their end dates separately.
- Check trading costs. Review the bid-ask spread and any commissions or account charges for your broker, taking into account how often you expect to trade.
- Review price versus net asset value. Check whether the ETF is trading at a premium or discount when you plan to place an order.
- Compare tracking over matching periods. Use comparable date ranges and benchmark definitions rather than relying on one isolated performance figure.
- Match mechanics to your account. Consider share price, fractional-share availability, and your expected purchase size.
- Recheck before investing. Fees, waiver terms, and market conditions can change; use the latest prospectus and current trading information.
The figures and examples above do not establish a complete current ranking of Nasdaq-100 ETFs. Your time horizon, tax situation, trading habits, account costs, and existing portfolio concentration can all affect which fund is suitable.
