My estimate
Pay, pretty sure it is over 700. UBS was 2500+400 accomodation a month. So over 700 a week and UBS was among that group of banks who 'wage fixed'.
Over 10 weeks, you are 6250 wage and 1000 for accomodation. Paid 7250. 11% on NI, 800ish. Income tax on that above 5000ish, which is 20% now or something? Under the tax regime. So the 2250 over you pay 420ish.
Total tax - 1220ish
Rent - 140ish a week, so over the 10 weeks, 1400
(or you can live it up and easily spend more than double this)
The rest: food (20), phone (5), random expenditure (?), any travel (5), gym (8), other half (?!?!), booze (15) etc. 30- to 60+ a day.. Actually, to spend 30 2100- to 4200+
Total spend estimate, 4720- to 6820+
Total saved, 2500+ to f. all.
Which explains how some people saved a few grand pretty easily and other managed to finish with about nothing.
Figures are probably better looking for those in M&A. Could be significantly better/worse in trading if you have some flare. Try not to play too many trading games when drunk.
