How the overtime calculation works
The calculator finds an approximate basic hourly rate from your annual salary and contracted weekly hours. It multiplies this by your overtime hours and overtime rate, then estimates the difference in annual PAYE take-home pay.
Important limits
This is designed for regular overtime with the same pattern all year. A real payslip can differ because overtime might be paid in only some periods, pensionable pay rules vary, and PAYE or National Insurance are calculated through payroll. Check your contract for the overtime rate and whether unpaid breaks count as working time.
PAYE and National Insurance estimates follow HMRC's 2026/27 employer rates and thresholds.
