State Pension Forecast Check: The Two-Minute Test Most People Skip

You are 42. Two children. A workplace pension you have not opened the statement for since the auto-enrolment reminder in 2018. An ISA you set up because the bank offered you a £50 bonus. A mortgage that is mostly interest for the next nine years. The retirement is one of those things you assume will sort itself out. You suspect you will probably be fine. You cannot prove it.

The State Pension forecast is the cheapest and fastest piece of clarity available. Two minutes. gov.uk. Your National Insurance number. The screen shows you the exact weekly amount you will get at State Pension age, the date it starts, and your NI record year by year. Most people who look are surprised by one of three things. The forecast is lower than they expected because of NI gap years. The forecast date is later than they expected because the State Pension age is higher than they thought. The forecast has gaps that can be filled with voluntary National Insurance contributions for a known cost and a known lifetime gain.

What the Forecast Actually Shows You

Three things. The first is your State Pension age. For people born between 6 April 1961 and 5 May 1978 it is 66. For people born between 6 May 1978 and 5 November 1978 it is between 66 and 67. For people born from 6 November 1978 onwards it is 67 today and rising to 68 by 2046. The State Pension age is not a single number any more. It is a date that depends on when you were born.

The second is your State Pension amount. The forecast gives you a weekly figure and an annual figure. If your NI record is complete, the figure is £241.30 a week. If your record has fewer than 35 qualifying years, the figure is reduced pro rata. A reader with 28 qualifying years on a 35-year full pension will get roughly 80 percent of the full amount, around £192 a week, or about £10,000 a year. The shortfall is silent. The pension just pays less.

The third is your year-by-year NI record. This is the part of the forecast most people do not read carefully. It shows every tax year from when you started work, the NI class that was credited, and whether the year counts as a qualifying year for the State Pension. Years with a green tick are qualifying. Years with a yellow warning are not. Most readers in their late thirties and forties have between three and seven yellow years they did not expect.

Where the Gap Years Come From

The four common causes, in rough order of how often they show up on a real forecast. Years spent at university before tuition fees were means-tested, when student loans did not count as NI. Years on a low salary below the Primary Threshold, common in the first year or two of a career and in any year that included a long unpaid break. Years self-employed with profits below the Small Profits Threshold of £7,105, where Class 2 NI was not paid automatically. Years living or working abroad, where the NI record stops accruing unless the reader was paying voluntary Class 2 or Class 3.

A less common cause is years caring for children or ill relatives before 2010 that did not pick up Home Responsibilities Protection automatically. A rarer cause still is a year where the employer failed to deduct NI, which shows up as a missing year on the record and can usually be fixed by contacting HMRC with the payslips. Most gap years are ordinary. They are not the reader's fault. They are not the system's fault either. They are just years where the reader was not paying NI and was not aware of the consequence.

The Cost and the Gain from Filling the Gaps

Voluntary Class 3 National Insurance contributions are the standard way to fill a gap year. The Class 3 rate for 2026/27 is £18.40 a week, or £956.80 a year per missing year. You can usually fill gaps for the previous six tax years. The deadline for the 2020/21 tax year is 5 April 2027. The earlier you fill, the cheaper the gap year, because the rate rises each year.

Each qualifying year added to your record adds 1/35 of the full new State Pension to your weekly amount. In cash terms for 2026/27, that is £241.30 divided by 35, or £6.89 a week, or £358.50 a year, for life, with annual uprating under the triple lock. A five-year gap filled now costs £4,784 in Class 3 contributions and adds £1,792.50 a year to the State Pension for the rest of your life. The break-even on the five-year fill is roughly two years and eight months.

When Filling Is Not Worth It

Three cases where the maths does not work out. You are within ten years of State Pension age with a record that already has more than 25 qualifying years. The Class 3 cost per year is similar, but the lifetime gain is shorter and the gap is harder to close. You were contracted out of the Additional State Pension before 2016 and your forecast already includes a protected payment that does not benefit from extra qualifying years in the same way. You have other debt at a higher interest rate than the implicit return on the State Pension uplift, in which case the Class 3 money is better used to clear the debt first.

The general rule for most readers between 35 and 55 with three or more gap years on the record is that filling is worth it. The cost is small. The lifetime gain is large. The break-even is short. Most readers in this age band who check the forecast and act on it will find the maths is on their side.

How to Do the Two-Minute Test

Go to gov.uk/check-state-pension. Sign in with your Government Gateway user ID, or create one if you do not have one (a five-minute job the first time, two minutes every time after). You will need your National Insurance number. The screen shows your State Pension age, your forecast amount, and your year-by-year NI record. Read the year-by-year section. Count the green ticks. Note the yellow warnings.

If the forecast is below £241.30 a week, scroll down for the Class 3 quote. The forecast page gives you the exact cost of filling each of the previous six tax years. Note the cost. Then decide whether to fill them before the 5 April 2027 deadline for the 2020/21 year. The decision does not have to be made today. The forecast and the quote are saved on the page.

What If You Are Already Past State Pension Age?

If you are within six months of State Pension age, contact the Future Pension Centre instead of using the online service. If you have already reached State Pension age, contact the Pension Service for advice on voluntary NI for the years before you claimed. The basic rules are the same. The Class 3 cost is the same. The lifetime gain calculation is the same. The relevant deadline for filling a gap year is six years from the end of that tax year, not 5 April 2027, so a reader aged 66 in 2026 has more time than a reader aged 42.

The One Thing to Do This Month

Before 28 September 2026, do the two-minute test at gov.uk/check-state-pension. Sign in. Read the forecast. Read the year-by-year NI record. Count the gap years. If there are no gap years, the test confirmed the floor is the full new State Pension of £12,547.60 a year. If there are gap years, scroll down for the Class 3 quote. Note the total cost. Note the lifetime gain. Decide before 5 April 2027 whether to fill them.

The two minutes is the cheapest piece of financial clarity available in the UK. The forecast page tells you what the State Pension will actually pay. The NI record tells you whether you have any decisions to make before the deadline. The Class 3 quote tells you what those decisions cost. Most readers will find the maths is on their side. Most readers will find the decision is small. Most readers will wish they had checked five years earlier.

The State Pension is the floor of the retirement maths. The forecast is the number that decides whether the floor holds or whether it quietly drops to 80 percent of what you expected. Get the number before the end of the month.
