How does it work?

The SMP Calculator shows your monthly Statutory Maternity Pay after tax while on maternity leave. It can also work out your Enhanced Maternity Pay or Maternity Allowance and provides a monthly net pay amount after deducting your tax, national insurance, pension contributions and student loan.

You just need your due date and salary to see an initial Statutory Maternity Pay forecast. You can alter your pay details or maternity scheme to get a more accurate forecast afterwards.

The calculator makes a number of assumptions about your financial situation when calculating your forecast, you can find out more about these assumptions here.

The SMP Rates for 2020-2021 are
  • First six weeks: 90% of your average weekly earnings
  • The next 33 weeks: £151.20 per week or 90% of your average weekly earnings (whichever is less)
