Frequently Asked Questions
What is a break-even point?
The break-even point is where your total revenue equals your total costs — you're not making money or losing money. Every unit sold beyond this point generates profit.
How do you calculate break-even?
Break-even units = Total Fixed Costs ÷ (Selling Price per Unit - Variable Cost per Unit). The denominator is called the contribution margin — the amount each unit contributes toward covering fixed costs.
What's the difference between fixed and variable costs?
Fixed costs stay the same regardless of how many units you sell (rent, salaries, insurance). Variable costs change with each unit produced or sold (materials, shipping, labor per unit).
Why is break-even analysis important?
Break-even analysis tells you the minimum sales needed to avoid losses. It helps with pricing decisions, cost management, and understanding how changes in costs or prices affect profitability.
