Maternity Leave Calculator

Updated: Sep 30

Maternity leave is a period of time (up to 52 weeks) during which an employee is granted a period of absence before and after the birth of her child. During this period, if eligible, she will receive maternity pay for the first 39 weeks. You can use the calculator below to check and plan your employee maternity leave entitlement. You can also use our Maternity Pay Calculator to check how much paid leave your employee (if any) is entitled to.

Statutory Maternity Leave

Maternity leave is 52 weeks long and it is made up of:

  • Ordinary maternity leave - first 26 weeks

  • Additional maternity leave - last 26 weeks

The employee has the right to return to the same job on the same terms after ordinary maternity leave. If the employee stays on maternity leave for more than 26 weeks, she still has the right to return to the same job. If this is not possible as the business experienced significant changes, she may be offered a similar job. However, the job terms cannot be worse than before (e.g. salary, benefits, annual holiday allowance, seniority etc.)

Statutory Maternity Pay (SMP)

While on maternity leave, the employee may be entitled to 39 weeks of paid leave. For the first 6 weeks, the employer must pay 90% of the employee's average weekly earnings. For the remaining 33 weeks, the employer needs to pay the minimum between 90% of the employee's average weekly earnings and £156.66 per week. To find out more, read our maternity pay guide
