Calculates the negative inverse of the one-tailed TDIST function.

Sample Usage

T.INV(0.35, 1)

T.INV(A1, A2)


T.INV(probability, degrees_freedom)

  • probability - The probability associated with the t-distribution.

    • Must be greater than 0 and less than 1.

  • degrees_freedom - The number of degrees of freedom.

    • Truncated to an integer in the calculation if a non-integer is provided as an argument.

    • Must be greater than or equal to 1.


  • T.INV is to be used for the negative inverse of the one-tailed TDIST function.

  • Both arguments to T.INV must be numeric or a destination cell whose value is numeric.
