Cost Of Living in Oman
This questions a bit like how long is a peice of string but let's say that the average labourer earns approximately 150 Rials a month and management earns approximately 1000 Rials a month. The Dollars to Rials to conversion rate is approximately 2.5:1. So in normal speak that's 1 Rial buys you 2.5 US Dollars.
The standard of living is fairly high in Muscat but once you leave the capital conditions deteriorate considerably. Muscat is very beautiful and a beautification policy is in place in the city. They spend alot of money on making the city look attractive.
There are a number of big shopping centres in the city too that can give you much better prices than your local stores. Carrefour and Lu Lu are the two big shopping centres.
