I have no idea what you are calculating.
40.000 eur basic per year
60 x 12 x 60 EUR per sector = 43200 EUR per year
total 83200 per year = 6933 gross per month before tax.
If you take home about 6000 you should count yourself very lucky. But I hope the tax authority won't come knocking on your door.
In the Netherlands you would need 130.000 gross a year to make a similar salary. Which happens to be the Capt salary in easyJet Amsterdam.
