About This Calculator
Break-even analysis is the foundation of small business financial planning. Before investing in a business, you should know exactly how many units or how much revenue is needed to cover all costs. The break-even point separates loss from profit — every unit sold above break-even contributes directly to profit. Understanding contribution margin (price minus variable cost) shows how much each sale contributes toward covering fixed costs.
Industry Insights
- Breakeven in units is: Fixed Costs / (Price per Unit - Variable Cost per Unit). But breakeven in time is what matters for cash flow planning. If your fixed costs are $5,000/month and each sale contributes $50, you need 100 sales per month to stay alive.
- Most small businesses underestimate fixed costs by 20-30%. Include: rent, insurance, loan payments, subscriptions, accounting fees, licenses, owner salary (yes - pay yourself), and a 10% contingency buffer. Optimistic fixed cost estimates cause premature scaling.
- Breakeven analysis assumes linear relationships, but many businesses have stepped fixed costs. Your first employee is a $40,000+ step in fixed costs. Calculate a new breakeven point for each growth stage before committing to the expense.

Frequently Asked Questions
How do you calculate the break-even point?
Break-Even Units = Fixed Costs / (Price per Unit - Variable Cost per Unit). The denominator is called the contribution margin. For a $75 product with $35 variable cost and $8,000 fixed costs: $8,000 / ($75 - $35) = 200 units to break even. Break-even revenue = Break-Even Units × Price = 200 × $75 = $15,000/month.
What counts as a fixed cost vs variable cost?
Fixed costs stay the same regardless of sales volume: rent, salaries, insurance, software subscriptions, loan payments. Variable costs change with each unit sold: raw materials, packaging, shipping, sales commissions, payment processing fees. Semi-variable costs (like utilities) have a fixed base plus a variable component.
How do I use break-even analysis for pricing?
Work backwards: if you need $15,000/month to cover fixed costs and you can realistically sell 150 units, your price must generate at least $100/unit contribution margin ($15,000 / 150). Add your variable cost ($35) and you need a minimum price of $135. Compare this to what the market will bear.
How does break-even analysis help with business planning?
Break-even analysis answers the critical question: 'How many sales do I need to not lose money?' It helps evaluate whether a business model is viable, how sensitive profitability is to price changes, how much volume you need to justify adding fixed costs (hiring, new equipment), and what your margin of safety is above break-even.
