The system comprises contributory benefits and non-contributory benefits. Contributory benefits are payable to those unemployed persons with a minimum of 12 months' contributions over a period of 6 years preceding unemployment. The benefit is payable for 1/3 of the contribution period. The benefit amount is 70% of the legal reference salary plus additional amounts for persons with dependants. The benefit reduces to 60% of the reference salary after 6 months. The minimum benefit is 497 euros per month and the maximum is 1087.20 euros per month for a single person. The non-contributory allowance is available to those persons who are no longer entitled to the contributory pension and who do not have income above 75% of the national minimum wage. Sweden uses the Ghent system, under which a significant proportion of unemployment benefits are distributed by union unemployment funds. Unemployment benefits are divided into a voluntary scheme with income related compensation up to a certain level and a comprehensive scheme that provides a lower level of basic support. The voluntary scheme requires a minimum of 12 months membership and 6 months employment during that time before any claims can be made. Employers pay a fee on top of the pre-tax income of their employees, which together with membership fees, fund the scheme (see Unemployment funds in Sweden). The maximum unemployment benefit is (as of July 2016) SEK 980 per day. During the first 200 days, the unemployed will receive 80% of his or her normal income during the last 12 months. From day 201–300 this goes down to 70% and from day 301–450 the insurance covers 65% of the normal income (only available for parents to children under the age of 18). In Sweden tax is paid on unemployment benefits, so the unemployed will get a maximum of about SEK 10,000 per month during the first 100 days (depending on the municipality tax rate). In other currencies, as of June 2017, this means a maximum of approximately £900, $1,150, or €1,000, each month after tax. Private insurance is also available, mainly through professional organisations, to provide income-related compensation that otherwise exceeds the ceiling of the scheme. The comprehensive scheme is funded by tax. Saudi Arabia is an economic welfare state with free medical care and unemployment benefits. However, the country relies not on taxation but mainly oil revenues to maintain the social and economic services to its populace. Payment: 2000 SAR (US$534) for only 12 months for an unemployed person from ages 18–35  External links  By law, legally employed workers, regardless of their citizenship are eligible for unemployment benefits given that they are at least 18 years old, the employees contribute 1% to unemployment funds while the employers contribute 2%, and the workers are eligible to receive benefits after 600 days of contributions within the preceding 3 years of employment. the benefit payment is 50% for the average daily earnings based on the last 4 months and cannot be higher than the minimum wage (per industry).
