System Availability Calculator

Author(s): Elise Min, Melanie Davy

System failures are a serious issue that all companies should examine due to the related and considerable costs that result. Use this tool to calculate the key metrics for system availability in order to evaluate current system capabilities, identify vulnerable areas, and improve overall reliability.

This tool will assist with the calculation of:

  • MTBF: Mean Time Between Failure
  • MTTR: Mean Time to Repair
  • Availability
  • Downtime
  • Combined values for systems in a series or parallel configuration

Measuring and tracking system availability is essential to evaluate current system capabilities, identify vulnerable areas, and improve overall reliability.
