Overtime Cost as % of Payroll

Overtime pay as a percentage of total payroll, flagging unsustainable workload or understaffing

What is Overtime Cost as % of Payroll?

Overtime cost as a percentage of payroll is the share of total payroll paid as overtime. It shows how much extra labour is being bought through additional hours.

Some overtime is normal, but consistently high levels can signal understaffing, poor scheduling, higher cost and risk of burnout.

How to calculate it

Divide total overtime pay by total payroll cost, and multiply by 100.

For example, if overtime pay was 120,000 and total payroll was 2,000,000, the share is 6%.

Look at overtime by team and season, and compare with the cost of hiring additional staff.
