Enter your due date, your average pay, when you started with your employer and when you plan to start leave. The calculator checks the two tests for Statutory Maternity Pay, 26 weeks with your employer by the qualifying week and average earnings of at least £129 a week, then pays 90% of your average for 6 weeks and £194.32 or 90%, whichever is lower, for the next 33 weeks. It lists every pay week with dates, the qualifying week, the earliest leave start and when to tell your employer. If you do not qualify it estimates Maternity Allowance. Partners can switch to Statutory Paternity Pay, and anyone can add a company scheme and see a rough take-home figure for each stage.
