How's the latest post in the series Playing with Fire UK? Has it helped in any way? I can imagine your plan being so watertight that there wouldn't have been much for you to learn from it.
Great question
@never give up - I started a whiny post about how annoying it was to have so much in my pension rather than the ISA but then cooked some delicious food instead and shook myself out of it. The last Monevator case study was not dissimilar to how I was thinking about my savings in the past. The thing that caught me out was my last job move that massively raised my salary which moves the pension/tax needle and is an amazing problem to have that I am grateful for and won't beat up my previous non-psychic self about.
I've been playing with the excellent Engaging Data chart (highly recommended, this is not financial advice). For my current situation (as in right now), with a shift to 70/30 stocks/bonds,
this is what my success chances look like. I've assumed 10% spending flexibility and a PPAA of 55. That tiny red slice, that's the chances of this going wrong. Significantly more chance I'll be dead. (Caveats, US data, past performance, blah blah).
In two years' time, with no spending flexibility,
it looks like this. No red slice, would have worked in all the historic cases (caveats, past performance, blah blah).
This is exciting! If the PPAA shifts later, the chance of failure increase pretty quickly, BUT, that is assuming that the PPAA increases immediately the day before I turn 55 and I can't do anything about it. I'm comfortable that any pension changes won't happen immediately, and it doesn't take much spending flexibility to nudge that down.
These charts to show that the vulnerable bit is going to be just before the PPAA, which is what I suspected in my gut, but it's nice to have a chart confirm it. The charts aren't modelling that the mortgage costs won't increase with inflation, which will have the biggest impact just before the PPAA. It also doesn't account that the mortgage will cease entirely at some point - but that doesn't really impact the success chances unless the PPAA gets above 60.
All that does bring me to thinking that if I could get a competitive repayment remortgage on a longer term that could do a similar thing to an IO or offset mortgage that is harder to come by and remortgage. There seems to be talk about a 35-year-term being the new 25-year-term. I'd need to check what kind of awkward questions might be asked about expected retirement age though!
