OP I'm not going to post my level of savings on here because I don't actually think thats helpful to you and I want to provide you with some context to offset the usual crap that's appeared on this thread with people immediately weighing in claiming savings amounts in 6 figures.
Please know, that is not the norm in the UK.
There are plenty of stats that indicate that 1 in 3 people in the UK have less than £1000 in savings, and the average savings figures (which are something along the lines of £20k) are heavily skewed by a tiny minority who have huge savings.
So take with a pinch of salt all the people claiming huge savings pots as its a fact those people are in a very small minority.
Most people, unless they are saving very specifically for a house deposit, can't afford to maintain huge pots of savings because they need most of their money to actually pay their rent/mortgage, bills, and living costs.
For years my partner and I, with young kids, could only afford to save modest amounts eg managing to keep a pot of 2-5k, the sort of amount to cover emergencies like the boiler breaking or whatever. And honestly we felt we were doing quite well managing to have a little nest egg of that size while also having to shell out on stuff like childcare costs.
Yes now that kids are older and we've managed to increase our income we are managing to save decent amounts but we are well aware we're in a much more comfortable position than most.
Don't beat yourself up if you don't have 600k in a savings account at the age of 37 or whatever.
