Key takeaways
- Net Asset Value (NAV) represents a mutual fund's per-share value on a given business day.
- Mutual funds are priced only once per trading day after the market closes, unlike stocks that trade throughout the day.
- A lower NAV does not mean a fund is a bargain, and a higher NAV does not mean a fund is expensive.
- Comparing NAVs of different funds provides no meaningful insight into their quality or past performance.
What Is Net Asset Value
Net Asset Value, commonly known as NAV, represents a mutual fund's per-share value on a given business day. It is calculated by taking the total value of all the securities and cash held in the fund's portfolio, subtracting any liabilities, and dividing that result by the total number of fund shares currently owned by investors.
Unlike individual stocks that trade throughout the day on public exchanges, mutual funds are priced only once per trading day after the market closes. This means all buy and sell transactions executed on a specific day use that exact day's closing NAV, regardless of when the order was submitted during market hours.
Mutual Fund vs. Stock Pricing Frequency
How the Daily Calculation Works
At the end of every trading day, the fund's administrator prices every individual asset held within the portfolio using official closing market prices. If a fund holds hundreds of different securities, the total market value of all those holdings is summed up along with any dividend income and cash reserves.
Next, the fund subtracts operating expenses, management fees, and any other liabilities from that total asset value to determine the net assets. Dividing this final net asset figure by the total number of outstanding shares gives the final NAV per share published for that day.
Components of Daily NAV Calculation
| Calculation Step | Action Taken |
|---|---|
| Asset Pricing | Price every individual asset held within the portfolio using official closing market prices. |
| Total Valuation | Sum the total market value of all holdings along with any dividend income and cash reserves. |
| Liability Deduction | Subtract operating expenses, management fees, and other liabilities from the total asset value. |
| Per-Share Division | Divide the final net asset figure by the total number of outstanding shares to give the final NAV. |
Common Misconceptions About NAV
A common misunderstanding among investors is that a lower NAV means a fund is a bargain or that a higher NAV means a fund is expensive. In reality, NAV simply reflects the per-share value of the underlying assets, much like slicing a pizza into more or fewer pieces without changing the total amount of food.
Because NAV does not indicate whether a fund is cheap or expensive, comparing the NAVs of two different funds provides no meaningful insight into their quality or past performance. Instead, investors should focus on underlying holdings, expense ratios, investment objectives, and historical returns relative to appropriate benchmarks.
Evaluating a Mutual Fund Beyond NAV
Check underlying holdings
Examine the securities and assets actually held within the fund's portfolio instead of looking at the NAV.
Review expense ratios
Look at operating expenses and management fees deducted from the total asset value.
Assess investment objectives
Ensure the fund's goals align with your own investment strategy and time horizon.
Analyze historical returns
Review past performance relative to appropriate benchmarks rather than comparing NAV figures.

Frequently asked questions
What is Net Asset Value (NAV)?
NAV represents a mutual fund's per-share value on a given business day, calculated by taking total asset value minus liabilities, divided by total shares.
Does a higher NAV mean a fund is performing better?
No. NAV does not indicate whether a fund is cheap or expensive, nor does comparing NAVs of different funds provide insight into their quality or past performance.
When are mutual fund transactions processed?
All buy and sell transactions executed on a specific day use that exact day's closing NAV, regardless of when the order was submitted during market hours.
What factors are subtracted to find net assets?
Operating expenses, management fees, and any other liabilities are subtracted from the total asset value.

The bottom line
Net Asset Value measures a mutual fund's per-share value at the close of each trading day, but it should never be used as a metric to judge whether a fund is cheap, expensive, or high-performing.
