Lost Time Case Rate Calculator

The Lost Time Case Rate (LTCR) is a workplace safety metric used to calculate the number of work-related injury or illness cases that result in time away from work. It is expressed per 100 full-time employees and helps organizations assess how frequently serious incidents are occurring that lead to lost productivity.

Tracking LTCR enables companies to monitor trends in lost-time incidents and take corrective action to reduce workplace risks.

Why is Lost Time Case Rate (LTCR) Important?

Measuring Lost Time Case Rate is crucial for:

  • ๐Ÿ“‰ Identifying trends in serious workplace injuries
  • โš ๏ธ Highlighting areas where corrective action is needed
  • ๐Ÿงพ Maintaining compliance with OSHA and safety reporting requirements
  • ๐Ÿ“Š Benchmarking safety performance across sites or departments
  • ๐Ÿš‘ Reducing costly downtime and insurance claims

The standard formula to calculate LTCR is:

Numberย ofย Lostย Timeย Cases X 200,000 / Totalย Hoursย Worked

Where:

  • Lost Time Cases = Number of incidents that caused employees to miss one or more full shifts.
  • Total Hours Worked = Total employee work hours during the reporting period.
  • 200,000 = Represents hours worked annually by 100 full-time employees (40 hours/week ร— 50 weeks/year ร— 100 employees).

Reducing your LTCR requires a proactive safety approach:

  • ๐Ÿงฐ Provide comprehensive safety training
  • ๐Ÿ› ๏ธ Maintain equipment and eliminate known hazards
  • ๐Ÿงโ€โ™‚๏ธ Encourage early reporting and injury intervention
  • ๐Ÿ“‹ Investigate all incidents to prevent recurrence
  • ๐Ÿ”„ Rotate repetitive or physically demanding tasks
