How do you calculate unit pricing?
We back into unit price using your cost per unit and target gross margin. Price per unit = cost / (1 - margin).
How do discounts affect gross margin?
Discounts reduce unit price while costs stay the same, so margins drop on higher tiers. The table shows the actual margin for each tier.
