State Pension is usually based on the number of years of NIC someone has paid. The minimum required is ten years.
Women needed to pay 39 years to get a full basic State Pension (bSP). Men needed 44 years. That five year difference is because women used to get their SP at 60 while men had to wait until 65.
That has now been equalised and the current SP age is 66 for both men and women. That will rise to 67 between 2026 and 2028, and then to 68 between 2044 and 2046.
Someone age 80 or over now who only paid NIC for ten years would be entitled to £45.24 pw. That’s the current rate of full bSP of £176.50 x (10/39). For last year, 2024/25, that would have been £169.50 x (10/39) £43.46 (which is why I think the example on the gov.uk pages refer to £43).
Note. The Over 80 Pension is NOT based on NIC but will give someone a pension of £105.70 pw irrespective of why they were getting less than this. The rules say:
You can claim the over 80 pension if all of the following apply:
•you’re 80 or over
•you do not get basic State Pension or your basic State Pension is less than £105.70 a week in 2025 to 2026
•you were resident in the UK for at least 10 years out of 20 (this does not have to be 10 years in a row) - this 20 year period must include the day before you turned 80 or any day after
•you were ‘ordinarily resident’ in the UK, the Isle of Man or Gibraltar on your 80th birthday or the date you made the claim for this pension, if later
Women born after 5 April 1953 need 35 years to get a full new SP currently £230.25. Someone with only ten years of NIC will get £65.78 - £230.25 x (10/35).
Note. There is NO similar top-up provision under the new SP rules i.e. if you reached SP age after 5 April 2016. The oldest women receiving new State Pension now are 72 (born after 5 April 1953) I have not heard of any plans to introduce a similar top up for them when they reach 80.
There is Pension Credit to top someone’s income up to minimum of £227.10. No single pensioner should have an income of less than this. That is only £3.05 less than the full nSP.
There is a lot of argument over the differential in basic SP and new SP, but as Doodledog explains, that isn’t taking into account the Additional State Pension (aSP) earned through paying into SERPS/SSP. That contribution scheme was abolished in 2016.
As others have said, nor does it take into the account the women who were expecting to receive their SP at 60 and had to wait (and work) up to another six years. I calculate I “lost” £40,000 due to that.
Nor (as DD says) does it take into account the much more generous spousal SP inheritance provisions for older pensioners. Some will have inherited both their husbands bSP and aSP. This chart and further links explain:
www.lcp.com/en/our-impact/inherited-state-pensions-for-widows-and-widowers
With spousal inheritance it is possible to receive a pension under the old system of well in excess of £300 pw even close to £400 pw.
Under the nSP provisions you can still inherit up to 50% of a spouses aSP but not if you were widowed before the age of 55 as I was. The rules for younger widowers are brutal. If I live to 83, I will have lost over £25,000 due to that. Because I was widowed at 51 I currently receive £25 week less pension than someone who was widowed at 55 based on exactly the same spousal SERPS.
Former Pensions Minister under the Coalition government Steve Webb, the architect of the single tier pension, and Moneybox’s Paul Lewis have both explained that the ultimate aim of the single tier pension (nSP) was that it would be cheaper in the long run for the government. That’s borne out by this article from Paul Lewis:

As he says there: Three million old state pensioners get more than the standard £221.20 a week the (then) new state pension. So comparing just the basic pensions of £221.20 and £169.50 is misleading. Most people get more or less than those standard amounts.
In answer to silverlinings question. If you work more than the maximum number of years needs to get a full pension you won’t get any more pension for it. I worked and paid NIC for 50 years. Only 35 count. I still don’t get a full SP due to a large rebate derived amount (RDA) due to being contracted out of SERPS. I do of course receive an occupational pension (although I worry about how long that may last if Reform come to power, cause a City meltdown as Truss did and pension funds fail as a result with no quantitative easing to save them this time - but that's another discussion).
As the expression goes - It’s complicated. The letter I requested and received from DWP asking for an explanation of how my SP is calculated runs to nine pages!
I don’t know, but I suspect the four year difference in the number of years required to get full bSP (39) or full nSP (35) is to do with changing lifestyles. The single tier pension is all anyone who entered the workplace after 5 April 2016 will receive. It’s more likely that they will enter the workplace at age 21 after university compared to previous generations who may have entered the workplace at 14, 15 or 16.
