The Family Resource Simulator (FRS) is a web-based tool developed by the National Center for Children in Poverty. It simulates the impact of federal and state “work support” benefits on the budgets of low- to moderate-income families. Work supports include earned income tax credits, child care subsidies, health care coverage, food stamps, and housing assistance. The FRS generates results that illustrate how a hypothetical family’s resources change as earnings and expenses change, taking public benefits into account.
