I know your figures are correct
They weren't correct. I forgot to change the assumptions in the calculator - I believe the TPS has a 50% spouse pension and is index linked to RPI. If you add in those benefits, the pot required grows to around £1.3 Million, and someone on £50K would have to save 43% of their salary for 40 years
and I know that, logically, things couldn't continue like that. But, in the same vein that Rog wrote earlier, it's a shitter when you are promised the final salary pension that your predecessors have been getting for years when you start out, only to have it taken away later. It's only human nature human nature to feel aggrieved. Her retirement age is now 67 and, to be honest, it's quite difficult to work out exactly what she will get. TPS website is still showing her benefits from the 1/80th contributions, so far about £13500 pa and a lump sum of, I think, around £35K. That's at 60, no mention of how it builds after that.
I understand people may think like that, but it's wrong thinking. If she was a member of the TPS prior to 2007, then she has a preserved pension age of 60. And assuming your wife was within 10 years of retirement in 2012, then she's still in the 1/60th scheme, with a scheme retirement age of 65.
https://www.teacherspensions.co.uk/reform/members/at-a-glance.aspxWhat usually happens when they change rules is that benefits built up to the date of the change are preserved, and then updated by statutory amounts - often CPI or RPI. They don't "have it taken away later". They just stop adding to it for future years. So your wife should have something like...
(Years prior to 2007)/80 * Salary in 2007 * (CPI from 2007-now) payable at 60
plus
(Years 2007-2015)/60 * Salary in 2015 * (CPI from 2015-now) payable at 60
plus
(years 2015-now) in whatever scheme she is in now - possibly still the 1/60ths one payable at 60.
Sometimes they can transfer your rights under the old scheme into equivalent rights in the new scheme - I don't know if the TPS did this. But the rights in the new scheme must be equivalent to those already built up in the old scheme - by Law.
Think of it this way - she was (till 2007) paying for roughly 25% of the true value of her pension. She is now paying roughly 50% of the true value of her pension. Most private sector employees would bite your arm off for that kind of deal.
