Circular References In Financial Models

This topic practices a core modeling concept, understanding when a calculation depends on itself either directly or through a chain of linked formulas. In investment banking interviews, candidates are often tested on circularity because it comes up frequently in debt schedules, revolver modeling, and interest calculations, where one line item changes another input that then feeds back into the original formula. The question checks whether you can recognize the feedback loop, explain why it happens, and think clearly about how model dependencies are built.
