What the specialists actually think about margin analysis

Why profitability feels harder than it should

Most of us analyze profitability with tools built for a different era. Spreadsheets overflow with tabs no one remembers creating, formulas break when someone adds a column, and by the time you reconcile the data, the quarter has already changed. Kieran Flaherty once told me his team spent more time fixing their model than using it.

The real trouble is not calculation—it is context. You can measure margin down to the decimal, but if you do not know which products subsidize others or where overhead lands unevenly, the number just floats there, unhelpful. What matters is knowing which levers to pull and what happens when you do.

When analysis becomes interpretation instead of archaeology, decisions stop feeling like guesses. That shift does not require new theory—just better alignment between the data you have and the questions you keep asking.
