What is contribution margin?

It's the price per unit minus the variable cost per unit — the amount each unit sold contributes toward covering fixed costs before you start making profit.

What happens if price is lower than variable cost?

Break-even is impossible — every unit sold loses money, so the result shows as unavailable until price exceeds variable cost.

Are fixed and variable costs different from the Profit Calculator's cost fields?

Yes — this tool is specifically about per-unit economics (fixed vs. variable costs), while the Profit Calculator works from a single period's total revenue and costs.
