Absence Rates Cost (Annual) Calculator
Estimate the annual cost of employee absence using your workforce size, absence rate, working days, daily employment cost and additional costs.
Overview
Use this annual absence cost calculator to estimate how much employee absence may cost your organisation. Enter your average workforce size, scheduled working days, annual absence rate, average daily employment cost and an allowance for additional absence-related costs.
How it works
The calculator first multiplies the workforce by scheduled working days to estimate total available working days. It applies the absence rate to calculate lost employee-days, then multiplies those days by the average daily employment cost. Finally, it adds the selected percentage for indirect or additional costs, such as overtime, temporary cover, management time or reduced output.
How to use this calculator
- 1Enter the average number of employees during the year.
- 2Add the typical scheduled working days for each employee.
- 3Enter your annual absence rate as a percentage.
- 4Provide an average daily employment cost per employee.
- 5Choose an additional cost rate and review the annual estimate.

Frequently asked questions
What is an annual absence rate?
An annual absence rate is the percentage of scheduled working time lost because employees are absent over a year. It is commonly calculated as lost working days divided by total scheduled working days.
What costs should be included in daily employment cost?
You may include basic pay and employer-paid employment costs, such as pension contributions, payroll taxes, insurance or benefits, depending on the purpose of your estimate.
What does the additional absence cost rate cover?
It can represent costs beyond normal pay, including overtime, temporary staff, rescheduling, administrative time, training cover and reduced productivity.
Why are absence days shown as a full-time equivalent?
The full-time equivalent figure converts total lost days into the approximate number of full-time employee-years those days represent, using your working-days assumption.
Does this calculator distinguish between short-term and long-term absence?
No. It uses one overall absence rate. You can run separate calculations for different absence categories if you have separate rates and cost assumptions.
How can I use the result to assess absence reduction?
Try a lower absence rate and compare the annual cost estimates. The difference indicates the estimated cost reduction under the same workforce and cost assumptions.
