Understanding Break-Even Analysis
The foundation of pricing and business planning.
🏗️
Fixed Costs
Expenses that stay the same no matter how much you sell — rent, salaries, software subscriptions.
🧮
Contribution Margin
Selling price minus variable cost per unit. It's what each sale "contributes" toward covering fixed costs.
⚖️
The Formula
Break-even units = Fixed costs ÷ Contribution margin. Sell more than that and every unit adds to your profit.
Frequently Asked Questions
Everything you need to know about break-even points.
What is a break-even point?
The sales level where total revenue equals total costs. Below it you lose money; above it you profit. It's the minimum your business must sell to survive.
How do I lower my break-even point?
Three levers: raise prices, reduce variable costs per unit, or cut fixed costs. Even small improvements compound — a $5 higher price can cut hundreds of break-even units.
Should I include my own salary in fixed costs?
Yes, if you want the business to truly sustain you. Include a reasonable owner's salary in fixed costs for a realistic picture.
