so far so good...
It does depend on what you put away into share plans and pension. I am 10 plus year capt and take home around £4500. With that, I put 23% of my salary into the pension to add into what the company puts in (making a total around £2300 per month) and subscribe to the share plans (£500 per month) The takehome includes sector pay, so in summer it may go up a little. Every October, loyalty pay kicks in and I get 15%of my basic salary (£96600) in one fat lump sum, which swells the Oct paycheck to £11000.
Hope this helps.
