Mutual fund values update once per day, after the stock market closes at 4 p.m. Eastern time

The price you see for a mutual fund — called the Net Asset Value or NAV — is calculated only once each trading day, after 4 p.m. Eastern. This is different from individual stocks, which update constantly throughout the day. If you place an order to buy or sell a mutual fund at any time during the day, you will receive the NAV price calculated that same evening, not the price from when you submitted the order.

This daily-only pricing rule applies to almost all mutual funds, whether you hold them in a brokerage account, a retirement account, or through a workplace plan. The one exception is money market funds, which may calculate NAV more frequently, but even those typically post a single price per day for trading purposes.

Key Takeaways

  • Mutual fund NAV is calculated once per trading day after the stock market closes, not in real time like stock prices.
  • Any order you place — whether at 9 a.m. or 3:59 p.m. — will execute at that day's closing NAV, calculated after 4 p.m. Eastern.
  • The NAV reflects the total value of all the fund's holdings divided by the number of shares outstanding.
  • On days the stock market is closed, no NAV is calculated and no trades settle.

How the NAV is calculated and why it happens after market close

The NAV is the fund's total assets minus its liabilities, divided by the number of fund shares in circulation. To calculate it accurately, the fund company needs the closing price of every stock, bond, or other security the fund holds. Since the stock market closes at 4 p.m. Eastern, that is the earliest time all those prices are final and known.

Fund companies typically publish the NAV between 4 p.m. and 6 p.m. Eastern, depending on how complex the fund is and how many holdings it contains. A fund with 50 stocks may post NAV by 4:30 p.m., while a fund with international holdings or complex securities may take until 6 p.m. or later. Your brokerage or fund company will show you the previous day's NAV until the new one is posted.

What time your order executes if you trade during the day

If you submit a buy or sell order at 10 a.m., 2 p.m., or 3:59 p.m., it does not matter — you will receive that day's closing NAV. This is called forward pricing. Your order sits in a queue and executes at the NAV calculated after the market closes that same day.

If you place an order after the NAV has already been posted for the day — for example, at 7 p.m. Eastern — your order will execute at the next trading day's NAV. This is why timing within a single day does not affect your price, but the date you place the order does.

How NAV differs from the fund's market price on a stock exchange

Some mutual funds trade on stock exchanges like the Nasdaq or New York Stock Exchange, just like stocks do. When a fund trades on an exchange, its market price can move throughout the day and may differ from its NAV. This price difference is called a premium (if the market price is higher) or a discount (if it is lower).

Closed-end funds and exchange-traded funds (ETFs) commonly trade at premiums or discounts to NAV. If you buy a fund through an exchange during the trading day, you pay the market price, not the NAV. The NAV is still calculated once per day and published, but it is separate from what you actually paid. Most mutual funds sold through brokerages or directly from fund companies do not trade on exchanges and therefore do not have this issue.

NAV updates on weekends and market holidays

No NAV is calculated on days the stock market is closed — weekends, federal holidays, and days the exchange shuts early. If you place an order on a Saturday, it will not execute until the next trading day's NAV. The same applies to holidays like Thanksgiving, Christmas, and New Year's Day.

Some brokerages allow you to place orders on non-trading days, but those orders will sit until the market reopens. You will receive the NAV from the first trading day after you placed the order, not a price from the day you submitted it.

Why mutual fund pricing works this way

The daily NAV system exists to prevent fraud and ensure fairness. If mutual funds priced in real time like stocks, fund companies would have to value every holding constantly, which is expensive and creates opportunities for manipulation. The once-per-day pricing also prevents traders from exploiting time zone differences — for example, buying a fund based on morning stock prices and selling it after international markets move later in the day.

The Securities and Exchange Commission (SEC) requires this daily pricing structure for mutual funds. It is a trade-off: you do not get the exact price you want at the exact moment you want it, but you know the price is fair and calculated the same way for every investor.

What to expect when you check your fund's value online

When you log into your brokerage or fund company account during the trading day, you will see the previous day's NAV with a timestamp showing when it was calculated. Some platforms label this "Last NAV" or "Previous Close." This is the price your current shares are worth, but it is not live.

After 4 p.m. Eastern on a trading day, the new NAV will post. Your account value will update to reflect the new price. If you have set up price alerts or automatic rebalancing, those typically trigger after the new NAV is published, not during the day.

Frequently Asked Questions

If I place an order at 3:59 p.m., do I get today's NAV or tomorrow's?

You get today's NAV, calculated after the market closes at 4 p.m. The time you place the order during the trading day does not matter — all orders placed before the NAV is posted execute at that day's closing price. Orders placed after the NAV posts execute at the next trading day's NAV.

Can I see the NAV before the market closes?

No. The NAV cannot be calculated until all the fund's holdings have closing prices, which happens at 4 p.m. Eastern. Some platforms estimate what the NAV might be based on partial data, but the official NAV is published only after the market closes.

Why is my fund's market price different from its NAV?

This happens only if your fund trades on a stock exchange. Exchange-traded funds and closed-end funds can trade at a premium (higher than NAV) or discount (lower than NAV) because their prices are set by supply and demand during the trading day, not by the fund company's calculation.

Do international mutual funds update at a different time?

International funds still calculate NAV once per day after 4 p.m. Eastern, even though some of their holdings trade in other time zones. The fund waits for all markets to close and all prices to be final before calculating the NAV, which may take until 6 p.m. or later.

What happens to my order if I place it on a holiday?

Your order will not execute until the next trading day. It will sit in a queue and execute at that day's NAV. You will not receive a price from the holiday itself because no NAV is calculated when the market is closed.
