❓ Frequently asked questions
What is the break-even point?
It is the sales level where total revenue exactly covers total costs — you make zero profit but also zero loss. Selling beyond it means profit.
How is break-even calculated?
Divide fixed costs by the contribution margin per unit (selling price minus variable cost). The result is the number of units you must sell to break even.
What counts as a fixed cost?
Fixed costs stay the same whatever you sell — rent, salaries, insurance. Variable costs like materials rise with each unit produced.
