Quick answers
What if price is below variable cost?
Contribution margin turns negative and break-even is undefined — fix price or cost first.
What counts as fixed cost?
Costs that do not scale with each sale, such as rent, base salaries, and fixed tooling.
Does it work for SaaS?
Yes. A unit can be a subscription seat or monthly plan, not only a physical product.
