Frequently Asked Questions
What are fixed versus variable costs?▾
Fixed costs stay constant regardless of how many units you sell, such as rent, salaries and insurance. Variable costs scale with output, such as raw materials, packaging and per-unit labour.
Why round break-even units up?▾
You cannot sell a fraction of a unit, so the break-even point is the smallest whole number of units that makes profit non-negative. Selling any fewer leaves you at a loss.
