How this tool works

The calculator measures the shift from start to finish, handles an end time after midnight, subtracts the unpaid break and multiplies paid hours by working days. Monthly hours use 52 weeks divided by 12.

When it is useful

Useful for checking rotas, comparing job offers, estimating timesheets and understanding how breaks and overtime thresholds affect weekly pay.

Accuracy and unit standards

Pay is an estimate before tax, pension, holiday pay and other deductions or premiums. Different employers define overtime and paid breaks differently, so compare the result with your contract.
