Hi ask the tax man app will give you your net take home pay after tax, NI & pension contributions. £6.74/hr is taxed at 40%, £3.01 + £3.28 (voyage rate ie away from base) both take home approx .85p in the pound ie 15% is tax the rest is yours. The busy summer months you will do 85hrs + per month so you do the Maths 85x £6.74 less 40%, that is paid from push back to on chocks, the FDP is paid from check in to 1/2 an hour after chocks (£3.01 hr less your 15% tax ). Overtime (lots of it in the last few years) work on £300 take home after tax which includes both your flying pay (6.74) & your FDP(3.01) and you won't be far wrong, payments can range from 1-8 per month if you want it (we are only supposed to do two though : scheduling agreement but needs must mainly in summer ) so expect anything from (if your a first year F/O) £3300 upto £5000 + per month, there really is no exact figure to quote !!
