SPY vs VOO: Which S&P 500 ETF Is Better in 2026?

SPY vs VOO is not a battle between two totally different investments. Both funds track the S&P 500, both own the same large U.S. companies, and both can work as the stock core of a long-term portfolio.

The decision in 2026 is practical: choose VOO if you are a long-term investor who mainly cares about low cost. Choose SPY if you trade often, use options, or need the most liquid S&P 500 ETF on the market.

SPY vs VOO: 2026 Snapshot

The biggest difference is cost. On a $100,000 position, VOO’s 0.03% expense ratio is about $30 per year. SPY’s 0.0945% expense ratio is about $94.50 per year. That $64.50 annual gap is not dramatic in one year, but it compounds if you hold for decades.

The biggest advantage for SPY is tradability. SPY is the older, iconic ETF used by institutions, hedge funds, short-term traders, and options desks. That can matter if you place large trades, trade during volatile markets, or use options strategies. It matters much less if you buy once a month and hold.

Which Is Better for Long-Term Investors?

For most long-term investors, VOO wins. The funds are trying to deliver the same S&P 500 return before expenses. When the underlying index is the same, lower costs give the cheaper fund a small but persistent advantage.

VOO is also easy to pair with a simple investing plan. You can buy it on most major brokerages, reinvest dividends, and keep adding money over time. If you are automating contributions, the Dollar Cost Averaging Calculator can help model how recurring purchases may grow.

SPY is not a bad long-term holding. It is large, seasoned, and highly liquid. The case against it is simply that most patient investors do not need to pay the higher fee for the trading features that make SPY famous.

Which Is Better for Traders?

SPY wins for traders. When you care about intraday volume, bid-ask spreads, options chains, and execution flexibility, SPY’s scale is hard to beat. Many active investors use SPY because everyone else uses SPY, which creates more liquidity.

VOO is still liquid enough for normal investors. A person buying a few shares or investing a few thousand dollars usually will not notice a meaningful execution problem. The difference becomes more important for institutions, very active traders, options users, and investors placing large market-sensitive trades.

If you are not trading options, do not let liquidity distract you from cost. A fund can be liquid enough without being the single most liquid ETF in the category.

Fees: Why VOO Usually Wins on Cost

Expense ratios are the cleanest SPY vs VOO difference. Vanguard lists VOO at 0.03%, while State Street lists SPY at 0.0945%. Both numbers are low compared with many mutual funds, but VOO is meaningfully cheaper between these two.

The fee difference is small in dollars at first. It becomes more meaningful as your balance grows. A $10,000 position has an annual fee gap of roughly $6.45. A $500,000 position has a gap of roughly $322.50 per year, before any future expense-ratio changes.

This is why the boring answer is also the useful answer: if you want S&P 500 exposure for years, the lower-cost version is usually the better default.

Dividends and Yield

SPY and VOO pay similar dividends because both funds own S&P 500 companies. Any dividend difference is usually small and can move around with share price, timing, fund expenses, and the exact distribution schedule.

In September 2026, Vanguard’s VOO profile showed a 30-day SEC yield near 1%, and widely available SPY data also showed a yield around 1%. That does not make either fund an income fund. These are growth-oriented broad-market ETFs that happen to distribute dividends from the companies they own.

If your plan is to reinvest those dividends, remember that dividends in a taxable brokerage account can still be taxable even when reinvested. For a deeper compounding model, try the DRIP Calculator.

Taxes and Fund Structure

Both SPY and VOO are ETFs, which usually helps taxable investors compared with many traditional mutual funds. But they are not built exactly the same way. SPY is an older unit investment trust. VOO is a Vanguard open-end ETF share class of a larger fund structure.

For most investors, this structure difference is less important than account type, holding period, and whether you sell at a gain. Still, VOO’s structure is generally cleaner for long-term taxable investors because it gives the fund more operational flexibility.

If this holding sits in a taxable account, compare it with your broader asset location plan. Our asset location guide explains why broad stock ETFs often fit well in taxable brokerage, while bonds and high-income funds may belong elsewhere.

Overlap: SPY and VOO Are Basically the Same Portfolio

SPY and VOO both track the S&P 500. That means you should not buy both expecting meaningful diversification. Owning both mostly gives you two wrappers around the same large-cap U.S. stock exposure.

This matters if your portfolio already has VTI, IVV, SPLG, FXAIX, or another large U.S. index fund. You may already own most of the same companies. Use the ETF Overlap Calculator before adding another fund that looks different but behaves almost the same.

If you are deciding between the S&P 500 and total U.S. stock market exposure, read VTI vs VOO. VOO focuses on large U.S. companies. VTI adds mid-cap and small-cap exposure too.

Decision Guide: Which Should You Pick?

Pick VOO if…

• You are a buy-and-hold investor.
• You want the lower expense ratio.
• You are building a simple S&P 500 position for retirement.
• You use recurring contributions or dollar cost averaging.
• You do not need the deepest options chain.

Pick SPY if…

• You trade actively.
• You use S&P 500 ETF options.
• You place large orders where maximum liquidity matters.
• You care more about execution tools than the lowest long-term fee.
• Your strategy specifically references SPY.

A Simple Rule for Beginners

If you are asking which one to buy for a long-term investing plan, choose VOO and move on. The lower fee is useful, the fund is huge, and the portfolio is the same basic S&P 500 exposure people are looking for when they search SPY vs VOO or VOO vs SPY.

If you are building your first portfolio, also read how to invest in index funds. The fund choice matters, but your savings rate, time horizon, diversification, and ability to stay invested usually matter more.

For many frugal investors, the final answer is simple: use VOO as the long-term core, avoid owning duplicate S&P 500 funds by accident, and keep the portfolio boring enough that you can stick with it.
