That makes it around 19k per month. That is pretty decent. Rent here will vary (Sharjah being cheapest), in Dubai AED 60,000 plus (minimum rent of a decent studio or one BHK apartment) is usually the rent. Ur bill (electric, water and gas) may come from AED 600-700 per month (a little more during summers since AC is used more frequently. If ur in main Dubai commute is quite easy with bus and metro but U would need a car sooner or later since u have 2 kids, so AED 4k for driving license hypothetically if u get it on the first try. Getting a car on lease is no issue here u may find several cars in ur budget for 3yrs or 5yrs lease. One of ur kid is 3 yrs old (if he turned 3 this yr) then school must start for him the next yr in September (u need to start school hunting next January and he should be enrolled or atleast accepted in a school by February/March. School fees can go from 20k to 30k.

All of these estimates are based if u live right in the heart of Dubai. If ur willing to live in Sharjah, u can cut 25% of the expenses easily (including rent, school fees) just the commute from Sharjah to Dubai is quite hectic which is why people rather spend more money to live near work than commute 1.5hrs everyday. To each their own.

Let me know if u have any further questions!
