The purpose of the Off Payroll Worker (OPW) calculator is to provide departments with an idea of the expected costs when engaging individuals captured by the OPW rules.

Where departments have agreed to cover the cost of the employers NI and the apprentice levy invoice details entered into column C will calculate a total cost to the department.

Where the employers NI and apprentice levy are to be included in the invoice total details entered into column E will calculate the figures to be entered on to the UPS4 form before sending to Shared Services for processing.

The calculator is not designed to calculate the deductions the worker can expect to pay themselves.
