Excel - LOGNORMDIST Function



What is LOGNORMDIST Function?

The Excel LOGNORMDIST function retrieves xs cumulative lognormal distribution, where ln(x) indicates the normally distributed data with the remaining parameters mean and standard deviation. This function can be extremely helpful in analyzing enormous logarithmic data, finance management, especially stock market data, risk management, and the medical field. You may benefit tremendously from the LOGNORMDIST, which streamlines your logarithmic data.

Compatibility

This advanced excel function is compatible with the following versions of MS-Excel −

  • Excel for Microsoft 365
  • Excel for Microsoft 365 for Mac
  • Excel for the web
  • Excel 2021
  • Excel 2021 for Mac
  • Excel 2019
  • Excel 2019 for Mac
  • Excel 2016

The LOGNORMDIST function replaces the LOGNORM.DIST function in Excel 2010.

Syntax

The syntax of LOGNORMDIST function is as follows −

LOGNORMDIST(x,mean,standard_dev)

Arguments

You can use the following arguments with the LOGNORMDIST function −

Argument Description Required / Optional
X It specifies the numeric value to compute the LOGNORMDIST function. Required
Mean It indicates the ln(x)s mean. Required
Standard_dev It indicates the ln(x)s standard deviation. Required

Points to Remember

  • If any argument is other than numeric, the LOGNORMDIST function retrieves the #VALUE! Error.
  • If the x value is negative or equal to 0, then the LOGNORMDIST retrieves the #NUM! Error.
  • If Standard_dev's value is zero or negative, the LOGNORMDIST will return the #NUM! error.

Examples of LOGNORMDIST Function

Practice the following examples to learn the use of the LOGNORMDIST function in Excel.

Example 1

Assume the sample dataset where the X, Mean, and standard deviation values are specified. You can enter the formula =LOGNORMDIST(B3,B4,B5) in the B6 cell.

Excel LOGNORMDIST Function 1

After that, press the Enter key to get the computed value.

Example 2

If any argument is other than numeric, the LOGNORMDIST function retrieves the #VALUE! Error.

Solution

Excel LOGNORMDIST Function 2

Excel LOGNORMDIST Function 3

Example 3

Either the value of x is negative or equal to 0, then the LOGNORMDIST retrieves the #NUM! error.

Solution

You may enter the formula = LOGNORMDIST(B3,B4,B5) in the B6 cell and press the Enter tab. Here, the value of x is negative, that is, -31.

Excel LOGNORMDIST Function 4

Therefore, the #NUM! error is retrieved as the value of the x parameter is less than 0.

Excel LOGNORMDIST Function 5

Example 4

If Standard_dev's value is zero or negative, the LOGNORMDIST will return the #NUM! error.

Solution

You may enter the formula = LOGNORMDIST(B3,B4,B5) in the B6 cell and press the Enter tab.

Excel LOGNORMDIST Function 6

Therefore, the #NUM! error is obtained after executing this function.

Troubleshooting Issues with the LOGNORMDIST Function

  • You need to carefully write the syntax of the LOGNORMDIST function with the correct arguments; otherwise, incorrect results may arise.
  • Missing parameter values lead to the error.
  • Make sure the Standard deviation contains a positive value.
  • You need to provide the correct references inside the LOGNORMDIST function to get the correct results.
