Absence Rates Salary Calculator
Estimate the annual salary cost of employee absence using headcount, average salary, absence rate, working days and employer costs.
Overview
Use this Absence Rates Salary Calculator to estimate the annual salary cost of employee absence. Enter your workforce size, average annual salary, absence rate, scheduled working days and employer costs to see the estimated number of lost days and their salary value.
How it works
The calculator converts average annual salary into a daily salary by dividing it by the working days per year. It then applies the absence rate to calculate absent days per employee and multiplies this by the number of employees. Finally, it applies the employer-cost percentage to each absence day. The result is an estimate of the salary-related cost of paid time lost to absence; it does not measure the full business impact of absence.

Frequently asked questions
What is an absence rate?
An absence rate is the percentage of scheduled working time that employees miss over a stated period, usually a year. It can include sickness and other recorded absence, depending on your organisation's definition.
How is the cost of employee absence calculated?
This calculator estimates absent days from the absence rate, then multiplies those days by average daily salary and the employer-cost percentage you enter.
Does the calculation include the cost of replacement staff?
No. The result covers estimated salary-related cost only. Agency cover, overtime, training, productivity losses and administrative time should be assessed separately.
What should I include in employer costs?
You may include payroll taxes, pension contributions, insurance and similar costs paid by the employer. Use a rate that reflects your own payroll data where available.
How many working days should I enter?
Use the annual number of scheduled or paid working days that matches your salary calculation. A five-day work pattern is often around 260 weekdays before allowing for leave and holidays.
Can I use this calculator for a single department?
Yes. Enter the headcount, average salary and absence rate for that department rather than the whole organisation for a more targeted estimate.
