Overtime Pay Quick Facts
Essential insights into UK extra hours compensation
Understanding Overtime Compensation
Calculating your true earning potential with extra hours is straightforward once you know your base rate and multiplier. Here is how the math works.
Calculate Regular Weekly Pay
Multiply your standard hourly rate by your contracted weekly hours to establish your baseline weekly income before any extra shifts.
Determine the Overtime Rate
Apply your contract’s overtime multiplier (e.g., 1.5 for time-and-a-half) to your base hourly rate to find your premium hourly wage.
Calculate Weekly Overtime Earnings
Multiply your new premium overtime rate by the number of extra hours you work each week to find your weekly overtime income.
Project Annual Total
Add your regular weekly pay and overtime weekly pay together, then multiply by the number of weeks you work per year (typically 52) for your gross annual total.
