Requires the estimated cost of mandated expenditures and appropriations within the body of the bill

This bill requires that any legislative proposal creating or changing government spending must include the estimated cost directly within the bill's text. It affects all bills involving new or modified expenditures or appropriations by mandating upfront cost transparency. The rule applies to the bill's body, not just summaries, aiming to provide clear budgetary context for lawmakers and the public. (Procedural bill; summary adheres to 2-sentence limit as specified.)
