Maternity Pay and Tax Estimator UK

About the Maternity Pay and Tax Estimator UK

Planning for maternity leave? Understanding how much income you will receive during your time away from work is essential. The Maternity Pay and Tax Estimator for the UK gives you a fast and reliable way to calculate your Statutory Maternity Pay (SMP) and the amount of tax you might pay on it.

What Is Statutory Maternity Pay (SMP)?

SMP is the payment most employed women receive when they take maternity leave in the United Kingdom. It’s typically paid for up to 39 weeks and is subject to income tax and National Insurance. The payment structure is:

• 90% of your average weekly earnings before tax for the first 6 weeks
• Then £172.48 or 90% of your average weekly earnings (whichever is lower) for the next 33 weeks

How This Estimator Works

Our tool asks for your annual salary and your expected duration of maternity leave. It then calculates your weekly earnings and applies the SMP rules to determine your gross pay. You can also input your estimated tax rate, and the calculator will show your expected net maternity pay.
