Absence Rates Salary (Annual) Calculator
Estimate an employee's annual absence rate and the salary cost of days lost from work.
Overview
Use this annual absence rate salary calculator to estimate the percentage of working days an employee has missed and the approximate cost of those absences. Enter annual salary, annual working days, absence days, and any employer or replacement-cost allowances.
How it works
The calculator divides annual salary by annual working days to estimate a daily salary cost. It multiplies that amount by absence days, then applies the employer on-cost percentage and any cover-cost uplift. The absence rate is calculated by dividing absence days by total working days and converting the result to a percentage.

Frequently asked questions
How is the annual absence rate calculated?
The annual absence rate is absence days divided by working days in the year, multiplied by 100.
What should I include in annual salary?
Use the employee's gross annual pay. You may include regular contractual allowances if they form part of the normal cost of employment.
What are employer on-costs?
Employer on-costs are costs in addition to salary, such as employer payroll contributions, pension payments, benefits, and insurance. The applicable costs vary by employer and location.
Should I include replacement or overtime costs?
If absence normally requires paid overtime, agency staff, or temporary cover, enter a reasonable estimated uplift. Leave it at 0% if no additional cover is expected.
Does this calculator include lost productivity?
No. It estimates direct salary-related costs and optional cover costs only. Indirect costs such as delayed work, administration, and service impact are excluded.
