An ETF (exchange-traded fund) is a basket of securities, such as stocks or bonds, that trades on an exchange throughout the day like a stock -- many track a broad index such as the S&P 500, giving instant diversification in a single purchase. A savings account is a bank deposit that pays interest and is typically government-insured, making it one of the lowest-risk places to hold cash, though with more limited growth potential than an ETF.

A savings account trades higher potential returns for stability and same-day access to your money. An ETF that tracks the broad stock market trades that stability for the potential of significantly higher long-term growth, along with exposure to price swings, including the possibility of short-term losses. The right choice depends on your time horizon, how soon you may need the money, and your comfort with watching your balance move up and down.

A savings account tends to make more sense for money you may need on short notice -- an emergency fund, a near-term down payment, or any goal where a market dip right before you need the cash would be a real problem. An ETF tends to make more sense for long-term goals five or more years away, like retirement, where there is time to ride out short-term declines. Historically broad-market ETFs have delivered stronger average annual returns than savings accounts over long periods, though with year-to-year volatility a savings account does not have.

ETFs charge an ongoing expense ratio, a small annual percentage of your investment deducted to cover fund management, and you may also pay a brokerage commission or spread when buying or selling shares. Savings accounts generally carry no comparable ongoing fee, though some may have minimum balance requirements. Even small expense-ratio differences between ETFs can compound meaningfully over long holding periods.

Over long stretches of history, broad-market ETFs tracking indexes like the S&P 500 have generally outperformed savings accounts on an average annual basis, largely because equities carry more risk and investors are compensated for bearing it. Past performance over any historical window, including the one you selected above, does not predict future results, and shorter windows can show savings outperforming an ETF or vice versa purely due to timing.

Unlike a savings account, money invested in an ETF is not insured and can lose value, including the possibility of losing a significant portion of your principal during a market downturn. The calculations on this page use historical ETF adjusted closing prices, which already reflect reinvested dividends, and exclude the ETF's expense ratio, trading fees, taxes, and any recurring contributions, so real-world brokerage results will differ.
