Excel NORMSINV Function
The NORMSINV calculates and returns the inverse of the standard normal cumulative distribution that has an arithmetic mean of 0 and standard deviation of 1 with a given probability.
Note: NORMSINV has been replaced with NORM.S.INV. Although NORMSINV is still available in current versions of Excel, you should consider using the new function from now on, because NORMSINV may not be available in Excel’s future versions.
Syntax
=NORMSINV(probability)
Arguments
- probability (required): The probability corresponding to the normal distribution. It is the value at which you want to evaluate the inverse function.
Return Value
The NORMSINV function returns a numeric value.
Function Notes
- The #VALUE! error occurs if probability is nonnumeric.
- The #NUM! error occurs if probability ≤ 0 or probability ≥ 1.
Example
To get the inverse of the standard normal cumulative distribution with the probabilities as shown in the screenshot below, please copy or enter the formula below in the top cell C3, and press Enter to get the first result:
=NORMSINV(B3)
√ Note: After entering the formula, drag the fill handle down to apply the formula to the below cells.
Note that for the normal cumulative distribution (probability) that is calculated with NORM.S.DIST(z, TRUE), the NORMSINV function will return the z value based on the probability result. See screenshot:
