Rule one: Period costs hit your income statement immediately. No hiding, no delay. Rule two: They include things like sales salaries, insurance, advertising, and even the office snacks. Yes, the snacks matter!
Compare that to product costs (like raw materials and factory labor) which sit on the balance sheet as inventory until sold. Period costs? They’re the here and now of business.
A Little Real-World Story
I once worked with a bakery owner who was baffled by her low profits. We found a huge period cost: she was paying for three different delivery services that overlapped. We cut the two redundant ones, and boom—her profit rose by 20% the next month.
She didn’t change a single recipe. She just understood where her money was going versus where it was sleeping in inventory. That’s the magic of period costs.
