About Your State Pension Estimate
This calculation provides an estimate based on your inputs and current State Pension rules. For a more accurate forecast, check your National Insurance record and get a personalized State Pension forecast from the UK Government website. The State Pension alone may not provide enough income for a comfortable retirement - consider supplementing it with workplace or private pensions.
Understanding the UK State Pension
New State Pension
The New State Pension applies if you reached State Pension age on or after 6 April 2016.
- Full New State Pension: £221.20 per week (2024/25)
- Requires 35 qualifying years of National Insurance contributions
- Need at least 10 qualifying years to get any State Pension
- Based on your own NI record (with some exceptions)
- Increases each year by the highest of inflation, average wage growth, or 2.5% (the 'triple lock')
Qualifying Years
A qualifying year is a tax year in which you've paid or been credited with enough National Insurance contributions.
- Working and earning above the Lower Earnings Limit (£6,240 for 2024/25)
- Receiving NI credits (e.g., for unemployment, illness, or caring responsibilities)
- Paying voluntary NI contributions
- Years are not necessarily consecutive
- You may be able to fill gaps in your record by paying voluntary contributions
State Pension Age
The age at which you can claim your State Pension is gradually increasing.
- Currently 66 for both men and women
- Increasing to 67 between 2026 and 2028
- Set to increase to 68 between 2044 and 2046 (but may be brought forward)
- You can check your specific State Pension age on the UK Government website
- You can defer claiming your State Pension to increase the amount you get
Maximizing Your State Pension
Check Your NI Record
Review your National Insurance record to identify any gaps in contributions. You can do this online through your personal tax account or by requesting a State Pension forecast from the UK Government.
Consider Voluntary Contributions
If you have gaps in your NI record, you may be able to pay voluntary Class 3 contributions to fill them. This is often cost-effective, as the increase in your State Pension over time typically exceeds the cost of the contributions.
Claim NI Credits
You may be entitled to National Insurance credits if you're unemployed, ill, a carer, or raising children. Some credits are applied automatically, while others you need to apply for. Check if you're eligible for any unclaimed credits.
Consider Deferring
You can increase your State Pension by deferring when you claim it. For each 9 weeks you defer, your State Pension increases by 1%. This works out as just under 5.8% for a full year of deferral.
Frequently Asked Questions
The New State Pension, for those reaching State Pension age on or after 6 April 2016, is calculated based on your National Insurance record:
- You need 35 qualifying years of National Insurance contributions or credits to get the full New State Pension
- You'll get a proportion of the New State Pension if you have between 10 and 35 qualifying years
- If you have fewer than 10 qualifying years, you generally won't receive any State Pension
The calculation may be more complex if you were contracted out of the Additional State Pension at some point before 6 April 2016, or if you built up entitlement to the Additional State Pension under the old system.
For the 2024/25 tax year, the full New State Pension is £221.20 per week (£11,502.40 per year). This amount typically increases each year under the 'triple lock' guarantee, which ensures it rises by the highest of:
- Inflation (as measured by the Consumer Prices Index)
- Average wage growth
- 2.5%
A qualifying year for National Insurance is a tax year in which you've paid or been credited with enough National Insurance contributions to count towards your State Pension.
Ways to build up qualifying years:
- Working and paying National Insurance: If you're employed and earning above the Lower Earnings Limit (£6,240 for 2024/25), you'll pay National Insurance and build up a qualifying year.
- Self-employment: Paying Class 2 National Insurance contributions if you're self-employed.
- National Insurance credits: These can be awarded automatically or you may need to apply for them. Credits can be given for:
- Claiming certain benefits (like Jobseeker's Allowance or Universal Credit)
- Caring for a child under 12 (Child Benefit related)
- Caring for someone who is sick or disabled
- Being unable to work due to illness or disability
- Being on jury service
- Being on an approved training course
- Voluntary contributions: Paying voluntary Class 3 National Insurance contributions to fill gaps in your record.
A tax year runs from 6 April to 5 April the following year. You normally need National Insurance contributions or credits for at least 10 qualifying years (not necessarily consecutive) to get any State Pension.
You can check your National Insurance record online through your personal tax account to see if you have any gaps and how you might be able to fill them.
'Contracting out' was a system that ended on 6 April 2016 where employees could give up their right to the Additional State Pension (also known as the State Second Pension or SERPS) in return for either:
- A higher private or workplace pension, or
- A rebate of National Insurance contributions into a personal pension
How contracting out affects your State Pension:
If you were contracted out before 6 April 2016:
- Your starting amount for the New State Pension may be reduced by a 'Contracted Out Pension Equivalent' (COPE) amount
- This is because you paid lower National Insurance contributions during the contracted-out period
- In exchange, your workplace or private pension should include an amount that replaces the foregone Additional State Pension
You may have been contracted out if you were a member of:
- A private sector defined benefit (final salary or career average) pension scheme
- A public sector pension scheme (like NHS, teachers, civil service)
- Some defined contribution (money purchase) pension schemes before April 2012
Even if you were contracted out, you can still build up qualifying years towards the full New State Pension for any years from 6 April 2016 onwards, as contracting out was abolished when the New State Pension was introduced.
You can check if you were contracted out by looking at your old payslips (which may have the letter 'D', 'E', 'L', 'N', or 'O' in your National Insurance number) or by checking with your pension provider.
Yes, if you have gaps in your National Insurance record, you may be able to increase your State Pension in several ways:
1. Pay Voluntary National Insurance Contributions:
- You can usually pay voluntary Class 3 contributions to fill gaps from the past 6 tax years
- Special arrangements currently allow some people to fill gaps further back (to 2006 in some cases)
- For the 2024/25 tax year, Class 3 contributions cost £17.45 per week (£907.40 for a full year)
- Each full year you buy typically adds 1/35th of the full State Pension to your weekly amount (about £6.32 per week in 2024/25)
2. Check for Missed National Insurance Credits:
- You might be entitled to NI credits for periods when you were:
- Claiming benefits due to unemployment or illness
- Caring for someone for at least 20 hours a week
- Raising children (via Child Benefit claims)
- On jury service
- On approved training courses
- Some credits are applied automatically, while others require an application
3. Continue Working or Getting Credits:
- If you haven't reached State Pension age yet, you can continue to build up qualifying years by:
- Working and paying National Insurance contributions
- Getting NI credits through benefits or other circumstances
- Paying voluntary contributions for current years
Before paying for any gaps, check if it will actually increase your State Pension by getting a State Pension forecast and contacting the Future Pension Centre. Not all gaps will affect your final pension amount, especially if you already have 35 qualifying years or will build them up before reaching State Pension age.
Use our Private Pension Calculator to see how much you might need to save additionally to ensure a comfortable retirement.
For most people, the State Pension alone will not provide enough income for a comfortable retirement:
Current State Pension rates (2024/25):
- Full New State Pension: £221.20 per week (£11,502.40 per year)
- Full Basic State Pension (old system): £169.50 per week (£8,814.00 per year)
Retirement income needs:
According to the Pensions and Lifetime Savings Association (PLSA), for a 'moderate' retirement lifestyle in 2024, a single person would need around £23,300 per year, while a 'comfortable' retirement would require about £37,300 per year.
The gap:
This creates a significant gap between the State Pension and recommended retirement income:
- For a 'moderate' lifestyle: Gap of approximately £11,800 per year
- For a 'comfortable' lifestyle: Gap of approximately £25,800 per year
Additional income sources:
To bridge this gap, you'll likely need additional sources of retirement income such as:
- Workplace pensions
- Private pensions (like personal pensions or SIPPs)
- Other savings and investments
- Property (rental income or equity release)
- Continuing to work part-time
