Excel BETA.INV function
Description
The Excel BETA.INV function returns the inverse of the cumulative beta probability density function for a specified beta distribution. This means that if probability = BETA.DIST(x,alpha,…), the BETA.INV(probability,alpha,…) returns x.

Return Value
The BETA.INV function returns a numeric value.
Errors
#VALUE! error value appears when any argument is nonnumeric.
#NUM! error value appears when one of below situations occurs:
- Argument alpha <= 0;
- Argument beta <= 0;
- Argument x < A;
- Argument x > B;
- Argument A = B.
Remarks
If the argument A and B are omitted, the BETAINV function uses the standard cumulative beta distribution, A = 0, B = 1.
Version
Excel 2013 and later versions.
Usage and Examples
Example1 basic usage
To return the inverse of cumulative beta probability density function based on the provided parameters in table C2:C6, please use the BETA.INV function as below:
=BETA.INV(C2,C3,C4,C5,C6)
Or you can directly type the arguments in the formula like:
=BETA.INV(0.6,1,6,5,10)
Press Enter key.
