Hong Life CalculatorsUnderstanding the NAV calculator — concept and principle
Net asset value (NAV) is the value of one share of a mutual fund, ETF or other pooled fund. This calculator finds NAV per share from the fund's assets, liabilities and shares outstanding, adds any front-end sales load to give the offering price, and shows how many shares your investment buys and whether an exchange price is at a premium or discount.
How it is calculated
- Net assets = total assets − total liabilities.
- NAV per share = net assets ÷ shares outstanding.
- Offering price with a front-end load = NAV ÷ (1 − load), so the load is a share of what you pay.
- Shares you get = amount invested ÷ offering price.
- Premium or discount = market price ÷ NAV − 1 (only for exchange-traded funds and closed-end funds).
The principle
A fund is a pool of securities owned jointly by its shareholders. Valuing everything it owns at current market prices, subtracting what it owes (accrued fees, borrowings) and dividing by the number of shares gives each share's fair slice. US mutual funds compute NAV at least once each business day, usually after the market closes, and buy and sell shares at that price. ETFs and closed-end funds also trade on an exchange, where supply and demand can move the price away from NAV.
Worked example
Default inputs: assets 125,000,000 USD, liabilities 2,500,000 USD, 9,800,000 shares, no load, invest 10,000 USD, no market price.
- Net assets = 125,000,000 − 2,500,000 = 122,500,000 USD.
- NAV per share = 122,500,000 ÷ 9,800,000 = 12.50 USD.
- With 0% load, the price with the load is also 12.50 USD.
- Shares you get = 10,000 ÷ 12.50 = 800.
- No market price was entered, so the premium or discount shows —.
| Shares (units) outstanding | NAV per share |
|---|---|
| 2.45e+06 | $50.00 |
| 4.9e+06 | $25.00 |
| 7.35e+06 | $16.67 |
| 9.8e+06 | $12.50 |
| 1.22e+07 | $10.00 |
| 1.47e+07 | $8.33 |
| 1.96e+07 | $6.25 |
How to read the result
NAV itself does not tell you whether a fund is cheap or expensive; a fund with NAV 12.50 is not better value than one at 125. What matters is the fund's total return and costs. For closed-end funds, a persistent discount to NAV can be an opportunity or a sign of investor concerns. For ETFs, arbitrage usually keeps the price close to NAV.
Common mistakes
- Comparing funds by NAV per share instead of by returns.
- Forgetting that a front-end load means fewer shares for the same money.
- Expecting to trade a mutual fund at the price seen during the day; orders get the next computed NAV.
- Ignoring distributions, which reduce NAV on the ex-dividend date.
Frequently asked questions
How often is NAV calculated?
US mutual funds must calculate it at least once every business day, usually at the market close.
Why does NAV drop after a distribution?
Cash paid out to shareholders leaves the fund, so its net assets fall by the same amount.
What is a premium to NAV?
When an ETF or closed-end fund trades above the value of its holdings per share.
