Control Limit Calculator

Enter the control mean, the control limit and the standard deviation into the calculator to determine the control limit LCL and UCL.

Control Limit Formula

The following formula can be used to calculate the upper and lower control limits.

LCL = x – (l*x*s)

UCL = x – (-l*x*s)

  • Where LCL is the lower limit
  • UCL is the upper limit
  • x is the mean
  • s is the standard deviation
  • l is the control limit
