Comparative shows year-on-year growth percentages, common size restates everything as a percentage of a base, like total revenue. Most folks will tell you to use comparative for trends and common size for structure. But I leaned way too hard on comparative statements early on, chasing those growth percentages like they were high scores. It took me missing a major cost creep in my own household budget—dadi's medicine and the damn electricity bill eating up more of my salary each month—to learn you need common size to really see what's *shrinking or swelling* inside the total. Now I run both, side by side, or you're not seeing the full picture.
