Absenteeism Rate Calculator
Absenteeism rate = absent days ÷ scheduled days × 100. A team of 25 with 22 working days and 18 absent days has an absenteeism rate of 3.27%. Calculate it for one person or a team, and see the hours and cost lost.
- Absenteeism rate = absent days ÷ (employees × workdays) × 100.
- Count unplanned absence; exclude approved vacation.
- Rates in the low single digits are typical in many industries.
- Bradford Factor = spells² × days — it highlights frequent short absences.
The absenteeism rate formula
Absenteeism rate = (total absent days ÷ total scheduled days) × 100, where scheduled days = employees × working days in the period. For hours-based teams use hours instead of days.
Example: 25 employees, 22 working days = 550 scheduled days. 18 absent days ÷ 550 = 3.27%. At 8 hours a day and $24 an hour, that is 144 lost hours and $3,456 in direct wage cost — before cover, overtime and missed work.

What counts as absenteeism
- Usually counted: sick days, no-shows, unauthorized absence, last-minute unpaid leave.
- Usually not counted: approved vacation and PTO, public holidays, bereavement, jury duty, parental leave and other legally protected leave.
- Partial days: late arrivals and early departures are often tracked separately as tardiness — see the tardiness calculator.
Be careful with protected leave: in the US, absence covered by laws such as the Family and Medical Leave Act or the ADA must not be held against employees in attendance policies.

The Bradford Factor
The Bradford Factor scores frequent short absences more heavily than one long absence: B = S² × D, where S is the number of separate spells and D the total days absent in a rolling 52 weeks. Ten one-day absences score 10² × 10 = 1,000; one ten-day absence scores 1² × 10 = 10. It is a prompt for a supportive conversation, not an automatic sanction — and it should exclude protected absences.
Worked examples
Real-world scenarios, worked through step by step.
Single employee
6 sick days out of 230 scheduled days: 2.61%.
Monthly team rate
40 staff, 21 workdays, 34 absent days: 34 ÷ 840 = 4.05%.
Cost
120 absent days a year × 8 hours × $22 = $21,120 in direct wages, plus cover costs.
Bradford Factor
4 spells totaling 6 days: 4² × 6 = 96.
Benchmarks
Absence rates vary by industry, season and how absence is defined. National statistics — such as the US Bureau of Labor Statistics data on absences from work — are useful context, but your own trend over time is more meaningful than a single benchmark. Track the rate monthly by team and look for changes, clusters (Mondays, Fridays, around holidays) and individuals with repeated short absences.
How to reduce absenteeism
- Measure it accurately first — attendance tracking records absence as it happens.
- Hold return-to-work conversations after every absence; they are supportive and they reduce casual absence.
- Look at workload and overtime: burnout drives sickness absence.
- Offer flexibility where the role allows it.
- Make the absence reporting process simple and clear.
- Review the trend monthly with team leads — the weekly manager reports include absence.
Track absence by type
| Absence type | Include in absenteeism rate? | Notes |
|---|---|---|
| Sickness (self-certified) | Yes | Main driver in most organizations |
| No-show / unauthorized | Yes | Track separately as well |
| Approved vacation / PTO | No | Planned absence |
| Public holidays | No | Not scheduled days |
| FMLA, disability, other protected leave | Report separately | Must not be used against employees |
| Bereavement, jury duty | Usually no | Policy-defined |
The return-to-work conversation
- Welcome backKeep it short and human — it is a check-in, not an interrogation.
- Check fitness for workIs the person ready, and do they need any adjustments?
- Update the recordConfirm the dates and reason for the absence record.
- Look at patterns gentlyIf there have been several absences, ask whether something underlying is going on.
- Agree next stepsSupport, referrals or a review date where needed.
Consistent return-to-work conversations are one of the most effective ways to reduce short-term absence, because they show absence is noticed and that support is available.
The full cost of absence
Direct wages for absent hours are only part of the cost. Add the cost of cover (overtime at 1.5× or agency staff), the lost output when cover is not available, the supervisor’s time rearranging work, and the effect on colleagues who pick up the slack. For shift-based operations the overtime premium alone can make an absence cost 1.5 times the wages. The overtime calculator shows the cover cost.
How different industries use it
- healthcare: High absence on clinical teams is often linked to fatigue; monitor consecutive shifts and short rest gaps alongside absence.
- call centers and bpos: Absence is built into staffing as “shrinkage” — measure the real rate so forecasts are right.
- construction and field service: An absent crew member can stop a job; quick cover decisions depend on knowing early.
- ecommerce and retail: Seasonal staff absence spikes around peak; plan a buffer from last year’s data.
- Office and remote teams: Unplanned absence is easier to hide remotely; consistent reporting matters more, not less.
What an absence rate means for a 100-person team
Absence rates translated into people and days, for 100 employees working 250 days a year at 8 hours a day:
| Absence rate | People absent on an average day | Absent days a year | Lost hours a year |
|---|---|---|---|
| 1.5% | 1.5 | 375 | 3,000 |
| 2.0% | 2.0 | 500 | 4,000 |
| 2.5% | 2.5 | 625 | 5,000 |
| 3.0% | 3.0 | 750 | 6,000 |
| 4.0% | 4.0 | 1,000 | 8,000 |
| 5.0% | 5.0 | 1,250 | 10,000 |
| 6.0% | 6.0 | 1,500 | 12,000 |
Moving from 4% to 3% recovers 250 working days a year — the equivalent of a full-time employee.

Frequently asked questions
How do you calculate absenteeism rate?
Divide absent days by scheduled days and multiply by 100.
What is a good absenteeism rate?
It depends on the industry; low single digits are common. Your own trend matters most.
Does vacation count as absenteeism?
No, approved vacation is normally excluded.
What is the Bradford Factor?
A score (spells² × days) that highlights frequent short absences.
Should protected leave be counted?
It should not be used against employees; exclude it from attendance discipline.
How much does absenteeism cost?
At least the wages for lost hours, plus cover, overtime and lost output.
What is the difference between absenteeism and tardiness?
Absenteeism is missing whole days or shifts; tardiness is arriving late.
How often should I measure absence?
Monthly by team, with a rolling 12-month view.
What causes high absenteeism?
Illness, burnout, workload, low engagement, caring responsibilities and poor management.
Can I use hours instead of days?
Yes — absent hours ÷ scheduled hours works the same way.
Is a 5% absence rate high?
It is higher than many organizations see, but compare with your industry and history.
How do I track absence automatically?
Use attendance tracking that records clock-ins against schedules.
How do I calculate absenteeism for a month?
Absent days in the month ÷ (employees × working days in the month) × 100.
How do I calculate absenteeism in hours?
Absent hours ÷ scheduled hours × 100. Use this for part-time or variable schedules.
What is a high Bradford Factor score?
Organizations set their own trigger points; any threshold should prompt a supportive conversation and exclude protected absences.
Does working from home reduce absenteeism?
It can reduce some short absences, but it can also hide unwellness. Track availability and wellbeing, not just presence.
What is unplanned absence?
Absence not approved in advance, such as sickness or no-shows.
How is absenteeism different from turnover?
Absenteeism is time missed by people who still work for you; turnover is people leaving. Rising absenteeism is often an early warning sign of turnover.
Should part-time employees be included?
Yes, using their scheduled days or hours, so the rate compares like with like.
