Frequently asked questions
What is the break-even formula?
Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit).
What counts as a fixed cost versus a variable cost?
Fixed costs stay the same regardless of sales volume (like rent), variable costs scale with each unit sold (like materials), correctly separating the two is essential for an accurate break-even number.
