For a couple with no children or 1 small child:

• 10,000 QAR basic salary

• Your package should also include a furniture allowance, health and Medical Coverage, free tickets to your home country per year for at least yourself, spouse, and three children.
• Also if your child is in school you will need a subsidy on their education.This will allow you to live in a modest 2-bdrm apartment with a decent lifestyle and allow you to save some money per month - that amount will be dependent on yourself.
