Just to throw a few more figures at you guys, an ezy F/O on the cadet scale takes home on average 2k a month. Thats after your monthly loan repayment has gone out. For those with Uni debts to service, the student loan people have finally caught up with me and I'm paying somewhere between 100-150 quid a month. It is a lot of debt considering that your next priority is probably a mortgage once you are settled at your base but it is manageable long term.
All the best.
