I don't think it's fair enough. For a villa of 3 bedrooms it will cost you 12k to 15k a month. For a flat of 3 bedrooms it will cost you 6k to 8k electricity and water bills not included. Plus your monthly installment of a 4x4 vehicle of say 2300 riyals per month. For food allowance of a family of 4 will cost you 3500 t0 4000 per month. Plus your internet and telephone bills of 233 riyals per month. Plus monthly educational fees of your children. You need at least 30,000 riyals monthly allowance.
