If you work through an umbrella company or are an employment agency managing temporary workers, accurately estimating pay is crucial. HM Revenue & Customs offers a reliable tool to help you determine both gross and net pay, along with the necessary deductions that apply to umbrella company arrangements.

Use this guide for a straightforward approach to calculating pay, ensuring financial transparency for both workers and agencies.

Materials and Information Required

Before you can estimate your pay, ensure you have the following:
  • The assignment rate (also called uplifted rate, umbrella rate, day rate, or hourly rate)
  • Basic worker details (age, employment status)
  • (If available) One or more of the following documents:
  • Your payslip
  • A pay/reconciliation statement
  • Assignment schedule
  • You can find the assignment rate in the job advert or by contacting your employment business or umbrella company.
