Most founders pile three different kinds of money into one number and call it their cost. Then they price off it, and the number lies to them. Pull the buckets apart and the real cost of one unit shows up.
Bucket 1 is the product. The factory price plus freight and duty. Together that is your landed cost, and it is the only cost that behaves like a true unit cost: make one more unit, pay it again. Every price you set and every quote you compare runs off this number.
Bucket 2 is the entry fee. Tooling, moulds, plates, samples, lab tests, artwork. You pay it once, whether the run is 200 units or 20,000. It looks like a unit cost only because you divided it by a small first run. Divide it by a bigger run and most of it disappears, which tells you it was never a property of the product.
Bucket 3 is the order. Pick, pack, postage and payment fees are charged when someone buys, and they scale with orders, not units. Someone who buys three units costs you one shipment, not three.
Why founders get this wrong. They add all three, divide by a 300-unit first run, and get a number that looks awful. Then they price too high, or they quit. The cost did not lie... the bucket did.
What this does not include: ads, software, your website, your time, and the units you give away. Those come out of margin later, which is exactly why margin has to be big.
