Here is issue THREE of the calcs with pearls of wisdom incorporated.
This my revised understanding to run past you to see if these calcs are there or thereabouts for a family of 2.0 kids moving from UK for a five year stint in the sun.
Monthly salary - 55,000 AED (assuming 70 ish hours / month)
Less
Rent for nice 4 bed villa -21,000 AED (assume rental prices continue downward)
Utilities 5,500 AED
Schooling top up 1,200 AED (including one off reg fees,enterance fees,buses,uniform allowance and interest on debenture loan). This is on top of the Fly Dubai 45,000 / year secondary school allowance.
UK Travel top up 500 AED (personal choice this one)
26,800 AED / month for non housing expenses. X 60 months = 1,608,000 AED
I have assumed that furniture moving and UK visit costs are more or less balanced by the leaving bonus ie....
23,000 to get furniture shipped there and back (and/or buy in Dubai).
15,000 / year travel back to UK (twice) (assuming no staff travel) X 5 = 75,000 AED
Plus
A leaving bonus of 17,260 for each year X 5 = 86,300 AED
SO I would be paid 1,608,000 AED for five years work (£268,000 ). mortgage) - Give the mess the UK is in...and the extended recession I think 6 AED to the pound works over an average of five years.
Less - Voids / mgt fees and a top end rental market depression in the UK I will lose £500 (£30,000/year) a month on my own house (not a chance of selling it).
£238,000
In the UK I would earn £240,000.
IF (and I know it is a big if) I could live on the same in Dubai as in the UK I would have lost £2,000 at the end of five years :-(
Standing by for any fine further feedback to knock out issue four .
