FAQ
What is contribution margin?
Price minus variable cost per unit — the amount each sale contributes towards fixed costs and then profit.
Why does it say I can never break even?
Your variable cost per unit is equal to or higher than the price, so each sale loses money. Raise the price or cut unit costs.
