Lost Time Case Rate Calculator
Formula: LTCR = (Lost Time Cases × 200,000) ÷ Total Hours Worked
What is Lost Time Case Rate (LTCR)?
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:
- 📉 Identifying trends in serious workplace injuries
- ⚠️ Highlighting areas where corrective action is needed
- 🧾 Maintaining compliance with OSHA and safety reporting requirements
- 📊 Benchmarking safety performance across sites or departments
- 🚑 Reducing costly downtime and insurance claims
Lost Time Case Rate Formula
The standard formula to calculate LTCR is:
Number of Lost Time Cases X 200,000 / Total Hours 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 × 50 weeks/year × 100 employees).
How to Reduce Lost Time Case Rate
Reducing your LTCR requires a proactive safety approach:
- 🧰 Provide comprehensive safety training
- 🛠️ Maintain equipment and eliminate known hazards
- 🧍♂️ Encourage early reporting and injury intervention
- 📋 Investigate all incidents to prevent recurrence
- 🔄 Rotate repetitive or physically demanding tasks
