Now here’s where it gets funny: you get to subtract things, too. If the supplier gave you a trade discount (like “buy 100 cases of soda, get a 10% break”), you take that off the invoice price. It’s like finding a coupon in your junk mail that actually works—rare, but glorious.
Also subtract any returns or allowances for damaged goods. If you sent back a pallet of squished tomatoes, you don’t pay for those sad little guys. And don’t forget purchase discounts for paying early—like when you pay your credit card bill before the due date and feel like a financial ninja.
The math that won’t make you cry
Here’s the formula, and I promise it’s simpler than assembling flat-pack furniture: Net Purchases = (Invoice Cost + Freight + Other Costs) – (Discounts + Returns + Allowances). That’s your cost of goods purchased. It’s the true price of all the stuff you bought, ready to be turned into money or dinner.

Picture this: you run a lemonade stand. You bought lemons, sugar, and cute paper cups. The lemons cost $10, the sugar $5, and the cups $3. But the farmer gave you a $2 discount for being a repeat customer, and you returned a bag of rotten lemons worth $1. Your cost of goods purchased is $10 + $5 + $3 – $2 – $1 = $15. That’s the number you would use to figure out if you’re making a profit—or just making yourself poor with thirst.
