Primary issue:The Atlanta Fed's CLIFF tools provide greater transparency to workers about potential public assistance losses when their earnings increase. The tools estimate eligibility for public assistance programs and the dollar amount of benefits, both in the current year and for future years along a career path. These features are intended to help a worker estimate the financial impact of a proposed earnings increase, reducing uncertainty and allowing the worker to plan for potential losses in public assistance. The CLIFF Tools National Pilot Implementation Evaluation was conducted to get feedback on tool functionality and to identify challenges that organizations face when adopting benefit cliff calculators like CLIFF.
