Here is the punchline. Once you know your Cost of Goods Purchased, you can calculate Gross Profit. That’s the money left over to pay for everything else.
Gross Profit = Sales – COGP. If your COGP is low, your profit is high. This is why billionaires obsess over pennies.
It’s like a video game. The lower your COGP (the health bar of expenses), the more coins you collect. Jeff Bezos didn’t get rich by ignoring this equation. He mastered it.

Next time you buy a pizza, think about the equation. The pizzeria bought dough, cheese, and pepperoni. That’s their COGP. They added a slice of profit.
If the price of cheese triples (crazy cow stuff), your pizza gets more expensive. You’re not mad at the pizzeria. You’re mad at the Cost of Goods Purchased.
See? It’s everywhere. It’s the invisible hand that shakes your wallet.
Go ahead. Tell a friend at dinner. “Hey, this taco’s price is a reflection of the vendor’s beginning inventory.” They’ll think you’re a genius. Or a weirdo. Both are fine.
Because now you know the secret. The equation isn’t boring. It’s the secret wiring of the whole economy. And you just read the manual.
