Mean Time Between Repairs

  1. This calculator can be used to determine the mean time between repair (MTBR) of a population of machines. [M] is the total machine count, [R] is the total number of repairs in the reporting period, and [T] is the reporting time interval. If you enter any three of these variables as inputs, the calculator will determine the fourth variable.

Input 3 of 4 variables to solve for the unknown.
