Why NAV is not just a number, but the key to understanding the value of the fund

Let's start with the main point: what the investor is actually buying

When you invest in a mutual fund or ETF, you are not just paying for the name. You are paying for the actual value of the assets owned by the fund, minus its liabilities. This amount is referred to as the net asset value — NAV (Net Asset Value). Think of NAV as an honest price list: it shows how much each share of your fund is actually worth.

How the actual cost is calculated

The formula is simple, but powerful:

NAV = (Total Assets - Total Liabilities) / Number of Shares Outstanding

Let's figure out what lies behind each part:

Assets are what the fund actually holds: stocks, bonds, cash, and other securities.

Liabilities are the debts of the fund, management fees, and other expenses that need to be deducted.

Outstanding shares — this is the total number of shares issued by the fund. It's important to understand here: this does not include treasury shares ( shares that the company has repurchased ).

By dividing the net assets by the number of shares, we get the value of one share — this is the NAV per share.

A specific example to make it clear

Imagine a fund that owns assets worth $500 million, while its expenses and debts amount to $50 million. There are 20 million shares of the fund outstanding.

Calculation:

Net assets = $500 million − $50 million = $450 million
NAV = $450 million / 20 million shares = $22.50 per share

This means that when you buy or sell shares of this fund, the price will be around $22.50 ( plus small fees ).

Three reasons why NAV matters

Performance Monitoring: NAV is updated every trading day. By comparing values over different periods, you can see how the fund is actually performing. If NAV is growing, the fund is making profits; if it is falling, something is going wrong.

Fair Price: NAV serves as a benchmark for setting the price when buying or selling mutual funds. Unlike the stocks of individual companies, the price of a mutual fund does not fluctuate throughout the day; it is fixed once, after the market closes.

Full transparency: NAV shows the real value of investments. This protects investors from manipulations and hidden fees.

Two Different Worlds: Open and Closed Funds

It is important to understand the difference here, because it changes everything.

Mutual funds and ETFs use NAV directly. Mutual funds buy and sell shares at the end of each trading day precisely at NAV. ETFs are traded on the exchange all day, but their price is still based on the NAV of the underlying assets.

Closed-end funds are a completely different story. After their initial placement (IPO), shares have a fixed number and trade like ordinary stocks. The price here is determined by supply and demand in the market, not NAV.

Result? Shares of a closed-end fund may trade:

With a premium (above NAV) — when investors are willing to overpay due to demand
At a discount ( below NAV) — when demand falls and the price drops

For example, if the NAV of a closed-end fund is $20, but the shares are trading at $22, that is a premium of $2. However, if they fall to $18 — a discount of $2. Experienced investors take advantage of these differences, but remember: the price does not always reflect the true value of the assets.

What Influences NAV in Real Time

NAV is a live indicator, it changes constantly:

Market movements play a key role. If the stocks and bonds in the fund's portfolio increase in value, the NAV increases as well. If they decrease, the NAV decreases.

Investment Income (dividends, interest) increases the value of the fund and, therefore, the NAV.

Fund Expenses (management fees, operating costs )reduce the NAV as they are deducted from the assets.

Since NAV is affected by both market fluctuations and internal expenses, this indicator is continuously updated and provides insight into the fund's performance in real time.

Practical Output

Net Asset Value (NAV) is not just a formula from a textbook. It is a tool that helps you make informed decisions when investing in mutual funds and ETFs. By understanding how NAV is calculated and what factors influence it, you will be able to better assess the fund's performance and understand what you are really paying for. NAV is the foundation for analyzing, comparing, and selecting funds, so do not overlook this indicator when making investment decisions.
