Common questions
Break-Even Calculator FAQs
Why must selling price exceed variable cost?
Otherwise each sale contributes nothing—or increases the loss—so fixed costs cannot be recovered.
What are fixed costs?
They are costs that do not change directly with units sold within the period, such as rent or base software subscriptions.
Is owner salary a fixed cost?
It can be if it is a planned, period-based cost. Classification depends on your business model.
