Before you write

  • Reporting an error? The page and the source that contradicts it are the two things that let it be fixed the same day
  • Want a calculator on your own site? The embed page has the code, free and with no sign-up
  • Wondering how a figure is worked out? The methodology page may already answer it

We cannot advise on your own situation — the calculators do not know your contract. For that, Acas is on 0300 123 1100.
