Bradford Factor Calculator
Calculate Bradford Factor to assess employee absence patterns
Calculate Bradford Factor
Bradford Factor is typically calculated over a 52-week period
Each separate period of absence counts as one spell, regardless of duration
Total number of working days absent during the assessment period
Bradford Factor Analysis
Example Scenarios
Employee A (Jack)
Spells: 1
Days: 30
Bradford Factor: 1² × 30 = 30
One long vacation - Low impact
Employee B (Steve)
Spells: 2
Days: 20
Bradford Factor: 2² × 20 = 80
Two periods - Moderate impact
Employee C (Amanda)
Spells: 10
Days: 20
Bradford Factor: 10² × 20 = 2000
Frequent absences - High impact
Key Insight: Even though Steve and Amanda had the same total days absent (20), Amanda's Bradford Factor is much higher due to more frequent absences.

Understanding the Bradford Factor
What is the Bradford Factor?
The Bradford Factor is a human resource tool that measures employee absenteeism based on the principle that frequent short absences are more disruptive to business operations than fewer, longer absences. It was developed by the Bradford University School of Management.
Why Use the Bradford Factor?
- •Identifies patterns of problematic absence behavior
- •Provides objective measurement for HR decisions
- •Helps detect potential workplace or personal issues
- •Supports fair and consistent absence management
Advantages and Limitations
Advantages
- • Objective and mathematical approach
- • Identifies disruptive absence patterns
- • Supports structured HR processes
- • Easy to calculate and understand
Limitations
- • Doesn't consider reasons for absence
- • May penalize employees with chronic conditions
- • Can create stress and reduce sick leave usage
- • Should not be used in isolation
Best Practice
Use the Bradford Factor as one component of a comprehensive absence management strategy. Always consider individual circumstances, medical conditions, and legal requirements when making HR decisions.
Legal Considerations & Best Practices
Legal Compliance
⚠️ Disability Discrimination
The Bradford Factor can indirectly discriminate against employees with disabilities or chronic conditions. Ensure reasonable adjustments are made and consider excluding disability-related absences from calculations.
📋 Data Protection (GDPR)
Absence data is sensitive personal information. Ensure proper consent, data security, and retention policies are in place. Limit access to authorized personnel only.
⚖️ Employment Law
Follow proper disciplinary procedures. The Bradford Factor should support, not replace, fair dismissal processes. Document all decisions and ensure consistency across employees.
Implementation Best Practices
Clear Communication
Ensure employees understand how the Bradford Factor works and what it means for them.
Regular Training
Train managers on proper use, legal considerations, and when to seek HR guidance.
Contextual Analysis
Always consider underlying reasons for absences and individual circumstances.
Support Systems
Provide employee assistance programs and wellness initiatives to address root causes.
💡 Pro Tip
Consider using multiple metrics alongside the Bradford Factor, such as overall absence rate, employee wellbeing scores, and qualitative feedback to get a complete picture of workforce health.

Frequently Asked Questions
What is a good Bradford Factor score?
A Bradford Factor score of 0-50 is generally considered acceptable. Scores between 51-125 may warrant informal discussion, 126-200 require formal review, and above 200 may need disciplinary action. However, these thresholds should be adapted to your industry and organizational context.
Is the Bradford Factor legally enforceable?
The Bradford Factor itself is not a legal requirement, but a management tool. However, any disciplinary action based on Bradford Factor scores must comply with employment law, including considerations for disability discrimination and fair dismissal procedures.
How often should Bradford Factor be calculated?
Most organizations calculate Bradford Factor scores quarterly or annually. Some prefer rolling 52-week periods for more current data. The frequency should align with your absence management review cycles and organizational needs.
Should all absences be included in Bradford Factor calculations?
Not necessarily. Many organizations exclude certain types of absence such as maternity/paternity leave, disability-related absences, jury service, or pre-approved vacation time. The key is consistency and clear communication of what is included.
Can the Bradford Factor be used for performance reviews?
While Bradford Factor can inform attendance discussions, it should not be the sole basis for performance evaluations. Consider it alongside other performance metrics, individual circumstances, and overall contribution to the organization.
