How to Use This Calculator
  1. Enter functional capacity evaluation result (%), job demand level (sedentary to heavy), and days off work.
  2. Enter current pain level (0-10 numeric rating scale).
  3. Read the return-to-work recommendation: 1 = not ready, 2 = modified duty, 3 = full duty.
  4. Review estimated return-to-work timeline based on functional capacity and job demands.
  5. Use results to develop a phased return-to-work plan with gradual demand escalation.

What each input means

Functional capacity (%)
Functional capacity evaluation result (0-100%).
Job demand level (1-4)
1=sedentary, 2=light, 3=medium, 4=heavy physical demands.
Days off work
Number of days absent from work due to injury.
Pain level (0-10)
Current pain level on numeric rating scale.

What each result means

Recommendation (1-3)
1=not ready, 2=modified duty, 3=full duty.
Full duty ready (0/1)
1 = functional capacity meets job demands.
Modified duty capacity (%)
Percentage of job demands the worker can perform.
Est. weeks to full duty
Estimated weeks until full duty return.
Chronicity risk (0-100)
Risk of injury becoming chronic/long-term disability.
Max hours per day
Recommended maximum work hours per day.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Functional capacity (%) = 70, Job demand level (1-4) = 2, Days off work = 30, Pain level (0-10) = 3 = 4 input(s) provided
  2. Calculate Recommendation
    3 = 3
  3. Calculate Full duty ready
    Full duty ready
    1 = 1
  4. Calculate Modified duty capacity
    Modified duty capacity
    100 = 100%
