Your numbers

Used to derive your State Pension age. State Pension age is 66 if you were born before April 1960, 67 if born 1960-1977, and 68 if born after 1977 (under current law).

Your actual figure is on your gov.uk record. As a rough guide, you accrue one qualifying year for each tax year you've paid NI (including most years you've claimed Child Benefit for a child under 12).

"Yes" covers employment, self-employment paying Class 2 NI, and qualifying credits (Child Benefit, Universal Credit, caring credits). "No" assumes you stop accruing qualifying years from today.

0

Each missing year can be filled by paying ~£907 in Class 3 voluntary NI. One year buys roughly £303/year of State Pension for life. The breakeven is reached in about three years of receipt.

This tool uses 2026/27 rates: full new State Pension £241.30/week (£12,547.60/yr) and Class 3 voluntary NI at ~£907.40/year. Future State Pension rates rise with the triple lock and may be meaningfully higher by your access age.

How the UK State Pension actually works

The full new State Pension (for anyone reaching State Pension age after 6 April 2016) pays £241.30 a week in 2026/27, which is £12,547.60 a year. To get the full amount you need 35 qualifying years of National Insurance contributions or credits. Below 10 years you get nothing. Between 10 and 35 years the pension is pro-rated: 20 qualifying years gets you 20/35 of the full rate.

Qualifying years are simpler than most people think. You accrue one for each tax year you:

  • Work as an employee earning above the Lower Earnings Limit (£123/week in 2026/27, even if no NI is actually deducted because earnings are below the Primary Threshold).
  • Work self-employed and pay Class 2 voluntary NI.
  • Claim Child Benefit for a child under 12 (the parent gets an NI credit).
  • Claim Universal Credit, Jobseeker's Allowance, Employment and Support Allowance, or carer credits.
  • Are on maternity, paternity, or shared parental leave.

Many people who think they're missing years actually aren't, because the credit system catches most situations where someone wasn't earning. The most common genuine gap is time spent abroad working in a country without a UK NI reciprocal agreement, or long-term unemployment without a benefit claim.

State Pension age explained

State Pension age (SPA) is the age from which you can claim your State Pension. It has risen steadily for both sexes since the 1990s and is on a published schedule to rise further. Under current law (April 2026):

BornState Pension age
Before 6 April 196066
6 April 1960 to 5 April 197767
After 5 April 197768 (subject to review)

Statutory reviews are scheduled for every five years and historically the trend has been one direction only. Anyone born after 1980 should probably plan around an SPA of 69 or 70 even though current law says 68 - the political reality is that life expectancy and Treasury cost projections push the line later each review cycle.

Voluntary Class 3 National Insurance: usually a no-brainer

If you have a gap in your NI record, you can pay Class 3 voluntary contributions to fill it. The 2026/27 rate is around £17.45/week, or about £907.40 per year of cover. Each year of cover adds 1/35 of the full new State Pension (£303/year) to your future entitlement for life.

The arithmetic is genuinely remarkable. Spend £907 once, get £303 a year for life from State Pension age. Breakeven at three years of receipt. The State Pension rises with the triple lock so the £303 also rises - meaning the real return is higher than the nominal arithmetic suggests. Almost no other DIY pension move in UK personal finance has a payback this fast.

The main constraint: you can only buy back gaps from the last 6 tax years under normal rules. A separate extended window (announced in 2023 and now running) lets people fill gaps back to 2006, but that closes on 5 April 2027. If you have older gaps and meet the eligibility criteria, the next 11 months are the last chance.

Worker-protective frame: this is one of the few cases where the UK pension system actually rewards the small saver disproportionately. A £907 spend that returns £303/year for life is a return profile no commercial pension product matches. The reason it exists is that the Treasury benefits from increased NI revenue today and the cost of the future pension uplift is spread across many decades of future taxpayers. The retail saver wins on the immediate maths.

Bridging from work to State Pension age

For early-retirement planners, the State Pension shows up partway through retirement - somewhere between 8 and 20 years after you stop working depending on when you stop. The portfolio has to bridge the gap. Once the State Pension kicks in, your portfolio withdrawal can drop by the State Pension amount, dramatically extending pot longevity.

A retiree spending £30,000/year with a full £12,500 State Pension only needs the portfolio to fund £17,500 once SPA hits. At a 4% sustainable withdrawal rate that's a £437,500 target instead of £750,000 - a 42% reduction in the portfolio you actually need.

The FI number calculator handles the two-phase maths if you want a precise number. The drawdown calculator models the year-by-year impact of the State Pension on pot longevity.

Frequently asked questions

How many qualifying years do I need for the full UK State Pension?
35 qualifying years of National Insurance contributions or credits, under the post-2016 new State Pension rules. Below 10 years you get nothing at all; between 10 and 35 years you get a pro-rated amount; above 35 years the entitlement is capped at the full rate.
How much is the full new State Pension in 2026/27?
£241.30 a week, which is £12,547.60 a year. The rate rises annually under the triple lock (the higher of CPI inflation, wage growth, or 2.5%). By the time someone aged 30 today reaches their State Pension age, the rate will be materially higher in cash terms - but planning in real (today's pounds) terms is the safer approach.
What is my State Pension age?
For most people retiring in the next few years it is 66 or 67. Born before 6 April 1960: SPA 66. Born 6 April 1960 to 5 April 1977: SPA 67. Born after 5 April 1977: SPA 68 under current law, but anyone born after 1980 should probably plan around 69-70 as future reviews push the line later.
Should I buy back missing NI years with Class 3 voluntary contributions?
Almost always yes if you have gaps. Each year of Class 3 voluntary NI costs ~£907 and adds £303/year of State Pension for life. Breakeven is reached in roughly three years of receipt. No commercial pension product offers a return profile this fast. Check your gov.uk NI record for gaps and act before the extended buyback window closes on 5 April 2027.
How is this different from the official gov.uk State Pension forecast?
The official forecast at gov.uk/check-state-pension uses your actual NI record from HMRC, which is the authoritative source. This tool gives a quick what-if estimate based on figures you supply. Use this for scenario planning ("what if I keep working another 5 years"); use gov.uk for your actual position. Sign in to gov.uk with your Government Gateway account to see the real number.
Does the State Pension count toward my FI / retirement target?
Yes, and significantly. A full State Pension of ~£12,500/year reduces what your portfolio has to fund from State Pension age onwards by exactly that amount. For a £30k/year retirement spend with a full State Pension at 67, the portfolio only needs to fund £17,500/year from 67 - a target of £437,500 at a 4% withdrawal rate instead of £750,000. Build this into your FI planning early; many UK FIRE plans underweight the State Pension and over-save as a result.
What about claiming a State Pension if I worked abroad?
If you worked in an EU country, the EEA, or a country with a bilateral social security agreement with the UK, your foreign contributions can count toward UK State Pension entitlement under the totalisation rules. Most non-EU countries don't have these agreements, so working in (for example) Australia, the US, or much of Asia typically doesn't add UK qualifying years. You can usually buy back those years via Class 3 voluntary NI from the UK side, though.
