Enter Work and Recovery Inputs
Formula Used
The calculator estimates fatigue with a weighted score from 0 to 100. Each input contributes a penalty based on load, stress, or weak recovery.
Work Fatigue Score = Hours Penalty + Sleep Penalty + Stress Penalty + Break Penalty + Commute Penalty + Intensity Penalty + Hydration Penalty + Recovery Penalty + Overtime Penalty + Weekend Work Penalty + Focus Drop Penalty + Discomfort Penalty
Core weights are capped so the final score stays within 0 to 100. Sleep debt and long work hours carry the largest influence because they strongly affect alertness, motivation, and sustainable performance.

FAQs
1. What does this calculator measure?
It estimates how strongly work demands and weak recovery combine to create daily fatigue pressure. The score helps you spot burnout risk patterns and workload imbalance early.
2. Is a higher score always bad?
A higher score means more fatigue strain, not personal failure. It signals that current work and recovery conditions may reduce focus, resilience, and sustainable performance.
3. Why are sleep and hours weighted heavily?
Sleep loss and long workdays strongly affect concentration, mood, reaction time, and recovery. They often amplify the impact of other stressors, so the model gives them more influence.
4. Can I use this for career planning?
Yes. It helps compare role demands, schedule designs, and personal energy limits. You can use repeated scores to decide whether a workload is sustainable over time.
5. Does this replace medical advice?
No. This tool is for self-assessment and planning only. Persistent exhaustion, sleep problems, or health symptoms should be discussed with a qualified professional.
6. How often should I calculate my score?
Weekly tracking works well for most people. Daily use can also help during intense projects, role transitions, or recovery periods when fatigue levels change quickly.
7. What is a good improvement target?
Aim to lower major fatigue drivers first, especially sleep debt, poor breaks, and extended hours. Even a ten-point improvement can reflect meaningful progress in recovery balance.
8. Why include commute and discomfort?
They add hidden strain that drains energy before or during work. These factors often raise fatigue even when headline workload numbers seem manageable.
