Clinical trial participation can come with significant out-of-pocket costs, including transportation, lodging, childcare, and lost wages from time off work. These logistical and financial burdens can limit access to trials, particularly for underrepresented populations, reducing diversity, recruitment, and retention. They may also hinder protocol compliance, ultimately impacting data quality.

The Participant Cost Calculator is designed to help participants, trial sites, sponsors, and other stakeholders better understand these financial burdens. It supports the development of fair and equitable compensation strategies that promote inclusive and sustainable trial participation.
