The Arkansas Semimonthly Family Support Chart is a tool used to determine the amount of child support to be paid based on the number of children in the family and the income of the parents. It is a chart that is updated twice a year to reflect the current cost of living in the state of Arkansas. The chart is divided into two types — Standard and Low-Income. The Standard chart is used for families with a combined gross income of more than $7,500 a month, while the Low-Income chart is for families with a combined gross income of less than $7,500 a month. The chart takes into account the number of children in the family, the age of the children, and the gross income of the parents. It then calculates a monthly support amount based on these factors and determines the amount of child support to be paid.
