How Statutory Maternity Pay works

  • SMP is paid for up to 39 weeks.
  • The first 6 weeks are paid at 90% of average weekly earnings, with no upper limit.
  • The next 33 weeks are paid at the lower of £194.32 a week or 90% of average weekly earnings.
  • Average weekly earnings are the 8-week average your payroll works out.

Employers can put SMP on the payslip with the payslip generator, and the sick pay calculator and paternity pay calculator cover the other statutory payments. Confirm any individual case with the official calculator below.
