I've been looking at this recently because I lived out of the UK for 17 years and am now a SAHM and hitting 50. I had a stress fest over this.
It used to be the case that anyone who paid a smidgen in NI got a state pension of some sort. Now you have to have paid in a minimum of 10 years to get anything. Then, depending on how many years you have, you get a pro rata or full pension.
The figure is £4.80 a week for every year you have paid in. Remember, you need to have 10 years and over to qualify. So, 4 years ago I checked and I had 10 years of NI before I left the UK. Phew.
So my pension if taken today would be £48.00 a week (£4.80 x 10).
Predictions are based on what you have paid so far and what it would be if you pay NI for the remaining, outstanding years to reach 35 NI years so I do not think they are accurate. I want to know what it is as of today.
When I moved back to the UK I heard that as a SAHM who doesn't qualify for CB, I could still register for CB, not get the cash and get NI contributions. I registered for CB, ticked the "don't want the cash" box and now I have 3 more years of NI. By the way, you can claim NI as a SAHM until youngest is 12.
So now my state pension as of today is 13 years of NI x £4.80 = £62.40 a week
According to the gov website, I can buy back 9 years. I've got 6 years to buy it back. This will cost me about £6K to buy, but I will be entitled to an extra £2,246.40 a year state pension if I do. So if I live till just shy of 71 I will have broken even. It's a gamble, but I think the alternative (pensioner poverty) is too risky. When I buy it back I will then have 22 years so my pension would be:
22 x £4.80 = £105.66 a week as of today
So, at 50, I will have 22 years. I am now working p/t and looking to up it so I could reach full state pension with consistent NI contributions. When I looked at this I panicked because I thought everyone got a state pension with minor differences. Not so and TBH I realise now that it is a pension scheme like any other and you have to pay into it. It's not a benefit like some of us think. You can't just move to the UK and get it. As a British Citizen who lived overseas, I am not entitled to it. I have to pay in as does everyone. Its not really any different to a normal pension plan except it is run by the government, is a bit shit and you won't get pay outs in advance or pass it on to your next of kin, although I believe you can inherit some of your partners state pension if you know what you are doing.
The state pension doesn't look a lot but that is not the way to view it. I see it as a very important base that can be built on. So if I reach the £168.60 a week, £674.40 a month, anything else I invest in a private pension is on top of that. With this base you only need to top it up by £325.60 privately to get £1K a month or great if you can top it up £825.60 to get £1,500 a month. I also want to put some distance between the 10 qualifying years and my own amount because I don't trust the government. They will move the goal posts by the time I retire.
OP, are you British? Have you lived here before? Have you paid any NI? Do you have 10 years? You may be able to buy some years to get you over the 10 and then get work to add to it.
Sorry for long post and hope my figures are correct.
