Thermogravimetric analysis (TGA) has been widely used as a tool to characterise the composition of materials such as Metal‐Organic Frameworks (MOFs). However, given their multifunctionality and structural complexity, examples of detailed methodologies for the exact calculation of the composition of complex MOF structures and MOF composites are lacking in the literature. Herein, we introduce a new straightforward methodology – based on the experimental ratio between the mass of a structure and its residue – for the exact calculation of the composition of almost any MOF material. We provide a detailed guide for the application of our methodology to different MOF materials, including MOFs in which multiple components decompose fully or partially within the same temperature range as the ligand, and diverse MOF composites, alongside with theoretical calculations demonstrating the exact mathematical determination. The methodology presented here can also be applied to many materials beyond MOFs.
