Maintenance and reliability teams can calculate common equipment, planning, downtime, cost, and compliance metrics without building spreadsheets first.
15 calculators available
Calculate availability, performance, quality, and overall equipment effectiveness from production time and count data.
Formula: Availability = Run Time / Planned Production Time; Performance = (Ideal Cycle Time x Total Count) / Run Time; Quality = Good Count / Total Count; OEE = Availability x Performance x Quality x 100
Calculate average repair time per repair event using total repair downtime and the number of repairs.
Formula: MTTR = Total Repair Downtime / Number of Repairs
Calculate average operating time between failures for repairable equipment using operating time and failure count.
Formula: MTBF = Total Operating Time / Number of Failures
Calculate average operating life before failure for non-repairable components using operating time and failed count.
Formula: MTTF = Total Operating Time / Number of Failures
Calculate planned maintenance percentage and the remaining reactive share from maintenance labor hours.
Formula: PMP = (Planned Maintenance Hours / Total Maintenance Hours) x 100
Calculate failures per hour or per day and estimate the average interval between failures when failures were recorded.
Formula: Failure Rate = Number of Failures / Total Operating Time
Calculate the percentage of direct hands-on maintenance time versus non-wrench time.
Formula: Wrench Time = (Direct Work Time / Total Time) x 100
Calculate annual maintenance spend as a percentage of replacement asset value without assuming one fixed currency.
Formula: Maintenance Cost as % of RAV = (Annual Maintenance Cost / Replacement Asset Value) x 100
Calculate total unplanned downtime, optional percentage of scheduled time, and optional estimated cost.
Formula: Total Unplanned Downtime = Number of Stops x Average Duration per Stop; Unplanned Downtime % = Total Unplanned Downtime / Total Scheduled Time x 100; Estimated Cost = Downtime in Hours x Hourly Cost
Calculate downtime percentage, uptime percentage, durations, and optional downtime cost from scheduled time.
Formula: Downtime % = (Total Downtime / Total Scheduled Time) x 100; Uptime = Total Scheduled Time - Total Downtime; Estimated Cost = Downtime in Hours x Hourly Cost
Calculate scheduled-time availability, available time, and downtime percentage from required time and downtime.
Formula: Availability = ((Scheduled Time - Downtime) / Scheduled Time) x 100
Calculate preventive maintenance compliance and the count of PM tasks that were not completed on time.
Formula: PMC = (Completed PMs on Time / Scheduled PMs) x 100
Calculate average maintenance cost per work order, repair, or intervention using total cost and event count.
Formula: MMC = Total Maintenance Cost / Number of Maintenance Events
Calculate backlog in weeks from ready backlog hours, technician count, and productive maintenance hours per technician per week.
Formula: Maintenance Backlog Weeks = Total Ready Backlog Hours / Available Weekly Maintenance Labor Hours
Calculate schedule compliance for all scheduled maintenance tasks, not only preventive maintenance.
Formula: Schedule Compliance = (Tasks Completed on Time / Tasks Scheduled) x 100
MaintBoard connects work orders, preventive maintenance, downtime, labor, parts and asset history so maintenance metrics can be reviewed from actual maintenance records.
