Also consider in your salary:
1. Accomodations allowance
2. Education for children
3. Transportation Allowance
4. US Foriegn Income Tax Exclusion Act (still file but pay no taxes if you stay out of the country for more than 330 days/year)

For young people or families, this is a great deal especially for the experience of having your kids go to a private school in another country. The good private schools are expensive and rigorous. Good luck.
