Cost of living in Tangier (Morocco) is 44% cheaper than in Amman (Jordan)
This comparison is lacking data. It provides a decent comparison, but it is not yet reliable. It is based on 1,055 prices entered by 115 different people.
For example, to keep the same standard of living that would require Dinar 2,100 in Amman you would need to make just about Dinar 1,174 (15,772 Dirham) in Tangier.
