Comprehensive Guide: How to Calculate Maternity Pay in the UK
Understanding how maternity pay is calculated is crucial for expectant mothers to plan their finances during this important life transition. This guide explains the statutory maternity pay (SMP) system, eligibility criteria, calculation methods, and additional financial support options available in the UK.
1. Understanding Statutory Maternity Pay (SMP)
Statutory Maternity Pay is the legal minimum payment that eligible employees receive from their employer during maternity leave. The current SMP rates (as of 2023/24 tax year) are:
- 90% of your average weekly earnings (before tax) for the first 6 weeks
- £172.48 or 90% of your average weekly earnings (whichever is lower) for the next 33 weeks
SMP is paid for up to 39 weeks, which is the standard maternity leave period in the UK.
2. Eligibility Criteria for SMP
To qualify for Statutory Maternity Pay, you must:
- Be an employee (not self-employed or a worker)
- Have given your employer the correct notice (at least 8 weeks before you want your SMP to start)
- Have been continuously employed for at least 26 weeks up to the ‘qualifying week’ (the 15th week before your due date)
- Earn at least £123 per week (the lower earnings limit for National Insurance) on average in the 8 weeks (or 2 months if paid monthly) up to the qualifying week
Important: If you don’t qualify for SMP, you might be eligible for Maternity Allowance instead. This is paid by the government rather than your employer.
3. How SMP is Calculated
The calculation of SMP involves several steps:
- Determine your qualifying week: This is the 15th week before your expected week of childbirth (EWC). For example, if your due date is 15 June, your qualifying week would be the week beginning 10 March.
- Calculate your relevant period: This is usually the 8 weeks (or 2 months for monthly-paid employees) up to and including your qualifying week. Your average weekly earnings are calculated based on this period.
- Check if you meet the lower earnings limit: Your average weekly earnings must be at least £123 (2023/24 rate) to qualify for SMP.
-
Calculate your SMP:
- First 6 weeks: 90% of your average weekly earnings
- Next 33 weeks: The lower of either £172.48 or 90% of your average weekly earnings
4. When SMP Starts and How Long It Lasts
SMP can start:
- From 11 weeks before your due date (the earliest you can start your maternity leave)
- From the day after your baby is born (if this is earlier than planned)
- From the day after you’re absent from work for a pregnancy-related reason in the 4 weeks before your due date
SMP is paid for a maximum of 39 weeks, which is the standard maternity leave period. You can choose to take:
- Ordinary Maternity Leave (first 26 weeks)
- Additional Maternity Leave (next 26 weeks)
You don’t have to take all 52 weeks, but you must take at least 2 weeks of leave after your baby is born (4 weeks if you work in a factory).
5. SMP vs. Occupational Maternity Pay
Many employers offer occupational maternity pay that is more generous than the statutory minimum. This is often called:
- Enhanced maternity pay
- Contractual maternity pay
- Company maternity pay
| Feature | Statutory Maternity Pay (SMP) | Occupational Maternity Pay |
|---|---|---|
| Legal requirement | Yes, minimum employers must provide | No, at employer’s discretion |
| Payment amount | Up to £172.48 per week (or 90% of earnings) | Often full pay for several weeks/months |
| Duration | Up to 39 weeks | Varies, often 6-12 months |
| Eligibility | Based on length of service and earnings | Often requires longer service |
| Funding | Employer can reclaim most from HMRC | Fully funded by employer |
Always check your employment contract or company policy to understand what occupational maternity pay you might be entitled to.
6. Maternity Allowance for Those Not Eligible for SMP
If you don’t qualify for SMP, you might be eligible for Maternity Allowance, which is paid by the government. To qualify, you must:
- Have been employed or self-employed for at least 26 weeks in the 66 weeks before your due date
- Have earned at least £30 a week in 13 of those weeks
The standard Maternity Allowance rate is £172.48 per week or 90% of your average weekly earnings (whichever is less) for up to 39 weeks.
7. Additional Financial Support
In addition to SMP or Maternity Allowance, you might be eligible for other financial support:
- Healthy Start vouchers: If you’re on benefits or pregnant and under 18, you can get vouchers to spend on milk, fruit and vegetables.
- Sure Start Maternity Grant: A one-off payment of £500 if you’re on certain benefits.
- Child Benefit: £24 per week for your first child and £15.90 per week for additional children.
- Universal Credit: You might get extra amounts if you’re responsible for a child.
- Tax-Free Childcare: Up to £2,000 per year per child (or £4,000 for disabled children) to help with childcare costs.
8. Tax and National Insurance on SMP
SMP is treated as earnings, so:
- Income tax and National Insurance will be deducted as usual
- It counts towards your taxable income for the year
- It affects your entitlement to tax credits and Universal Credit
Your employer will deduct tax and National Insurance from your SMP payments in the same way as your normal wages.
9. Returning to Work After Maternity Leave
You have the right to return to the same job after:
- Ordinary Maternity Leave (first 26 weeks)
- Additional Maternity Leave (next 26 weeks), unless it’s not reasonably practicable (e.g., if your job no longer exists)
If you decide not to return to work, you normally have to repay any occupational maternity pay that was more than SMP, unless your contract says otherwise.
10. Shared Parental Leave and Pay
Instead of maternity leave, you and your partner might be able to take Shared Parental Leave (SPL) and Shared Parental Pay (ShPP). This allows you to:
- Share up to 50 weeks of leave
- Share up to 37 weeks of pay
- Take time off separately or together
- Take time off in blocks with periods of work in between
ShPP is paid at the same rate as SMP (£172.48 or 90% of your average weekly earnings, whichever is lower).
| Feature | Maternity Leave | Shared Parental Leave |
|---|---|---|
| Total leave available | Up to 52 weeks | Up to 50 weeks (plus 2 weeks compulsory maternity leave) |
| Who can take it | Only the mother | Either parent (or both) |
| Pay | SMP for up to 39 weeks | ShPP for up to 37 weeks |
| Flexibility | Must be taken in one continuous block | Can be taken in separate blocks |
| Notice required | 8 weeks before leave starts | 8 weeks before each period of leave |
11. Common Questions About Maternity Pay
Q: Can I work while receiving SMP?
A: You can work for up to 10 ‘keeping in touch’ (KIT) days during your maternity leave without losing your SMP. These days are optional and must be agreed with your employer.
Q: What if my due date changes?
A: If your due date changes, your qualifying week and payment dates will be recalculated based on the new due date. You should inform your employer as soon as possible.
Q: Can I get SMP if I’m adopted?
A: If you’re adopting, you might be eligible for Statutory Adoption Pay (SAP) instead, which has similar rules to SMP.
Q: What if I have twins or multiples?
A: You’ll still only receive one SMP payment, regardless of how many babies you have. However, you might be eligible for additional benefits like Child Benefit for each child.
Q: Can I claim SMP if I’m made redundant?
A: If you’re made redundant during pregnancy or maternity leave, you’re still entitled to SMP for the full 39 weeks, even if you’re no longer employed.
12. How to Claim Maternity Pay
To claim SMP:
- Tell your employer you’re pregnant by the 15th week before your due date
- Give your employer a MATB1 certificate (usually provided by your doctor or midwife around 20 weeks before your due date)
- Tell your employer when you want to start your maternity leave (at least 8 weeks before you want it to start)
- Your employer will calculate your SMP and start paying it to you
If you’re eligible for Maternity Allowance instead, you’ll need to claim it through the government’s website or by phone.
13. Planning Your Finances During Maternity Leave
Preparing for the financial impact of maternity leave is crucial. Here are some tips:
- Create a budget: Calculate your expected income during maternity leave and compare it with your essential expenses.
- Build an emergency fund: Aim to save 3-6 months’ worth of living expenses before your baby arrives.
- Check your benefits: Use benefit calculators to see what additional support you might be entitled to.
- Consider childcare costs: If you’re planning to return to work, research childcare options and costs in your area.
- Review your insurance: Check if you need to update your life insurance or income protection policies.
- Plan for unexpected expenses: Babies often come with unexpected costs, so having some financial flexibility is helpful.
14. Recent Changes and Future Updates
The UK government occasionally updates maternity pay rates and eligibility criteria. Recent and upcoming changes include:
- April 2023: SMP rate increased from £156.66 to £172.48 per week (or 90% of average weekly earnings if lower).
- April 2024: Expected increase in SMP rate in line with inflation (exact amount to be confirmed).
- Neonatal Leave: New legislation introducing up to 12 weeks of paid leave for parents whose babies require neonatal care is expected to come into force.
