How to use this number
The net margin is what actually lands in your pocket per unit. The gross margin is almost always misleadingly high on its own.
- Check it against the price points you're actually charging, not a round number you picked without checking. A five-cent difference in cost or a five-point difference in commission moves net margin more than it looks like it should on a low-ticket item.
- The fixed card fee matters more than the percentage on cheap items. Try dropping the shelf price toward $1.25 and watch the net margin percentage move. This is exactly why the fixed fee, not the headline rate, is the number to watch on small purchases. See vending machine card reader cost & how it works for the full fee breakdown.
- Run it for your worst-margin item, not your best one, before deciding whether it earns a slot in the machine at all.
