Cost of living in Tangier (Morocco) is 31% 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 1,353 prices entered by 131 different people.
For example, to keep the same standard of living that would require Dinar 1,800 in Amman you would need to make just about Dinar 1,244 (16,542 Dirham) in Tangier.
