ERFC function in Google Sheets

Returns the complementary Gauss error function of a value.

=ERFC(z)

ERFC syntax and parameters

One argument, one required.

  • znumberRequired

    The number for which to calculate the complementary Gauss error function.

ERFC examples

Formulas you'll actually reuse.

  1. The complementary error function 1 − ERF(x) — a Gaussian tail:

    =ERFC(B2)

    Result0.1573

  2. The two-sided tail probability of a z-score — P(|Z| > z):

    =ERFC(B2 / SQRT(2))

    Result0.3173
