Index funds vs. ETFs: what is the real difference?

An index fund and an exchange-traded fund can hold exactly the same stocks. The difference is in the wrapper: mutual funds price once a day and let you invest exact dollar amounts, while ETFs trade all day like shares.

The case in plain English

In taxable accounts, ETFs have often been more tax-efficient because of how shares are created and redeemed. In a retirement account that edge disappears, and the better choice is usually whichever has the lower all-in cost at your provider.

None of this is a forecast, and past performance does not predict future results. Fees, taxes and time horizon matter at least as much as the product itself, and a plan you can stick with through a bad year usually beats a clever one you abandon.

Both track a market for a tiny fee, but how they trade, how they are taxed and how you buy them can differ in ways that matter.
