Well, I've enjoyed this zombie thread. I'm a nosy cow 
I have 6p left in my ISA. I did have a coin jar but it's been raided for all the 'good stuff' (silver) for bus fares to work, so with the copper that's left I'd estimate a quid or two. If I thought it was more I'd have paid the bus driver with the coppers as well- it's a bloody four hour round trip to work on foot!
I've £45 of my overdraft available, not sure I can count that as savings
Despite all this I am actually quite good with money, or at least I was when I had some money to be good with.
I've always been a careful saver, and never been interested in having new phones, clothes, gadgets and toys. I like travel, nice restaurants and such as much as the next person, but wouldn't go unless the cash was genuinely 'spare' for it, and day to day I can make a £10 food budget last just over a week (single and no kids!).
This thread has been really interesting. I think attitude to financial security combines with circumstances when it comes to how much you've got in the bank, and circumstances are definitely a dodgy variable to work with!
