I'm 39yrs old and this thread was a worrying read. Financial understanding is so key to life. So many don't plan ahead. If you want 30k/year in old age net of state pension, and apply the 4% draw down rule, you need 750k invested. You need to start early and keep at it. Or contribute more from a later date. State pension age will keep rising until it's all but phased out.
I started working at 25 after finishing my Masters. Bought a rough house with my wife in a good area at 27, did some DIY and flipped it on, did it again and now mortgage free in a 4 bed.
I started paying attention to my pension when I got to Director level at 37. If I hit my targets (which I do, coke hell or high water I make that happen) the bonuses and 20% salary contributions mean I max the annual allowance. Pot is only 200k now but can get close to 2m by 60 if I keep at it.
Shocks and saddens me that friends and colleagues haven't even considered how they will fund 30-40% of their lives, or what level of comfort and money they want, it's nuts.
Schools should teach this stuff. Aim high, push yourself, plan ahead.
If i was in my 50s, with a low pension, I'd remortgage the house. Go on Interest only. Put the cash in a pension over 3-4 years by maxing your contributions (60k a year) and top up your salary net pay from the mortgage money, once it's all (effectively) in the pension, the compounding will help a lot. Chip away at the mortgage with overpayments rather than an actual mortgage to maintain flex. Then when you retire at say 65 use the 25% tax free to clear any remaining mortgage. you'll have a much bigger private pension from the compounding on the mortgage lump you put in, to supplement the state pension.
