What is a Break Even Point?
The break even point is the level of sales at which your total revenue exactly equals your total costs — meaning you make neither a profit nor a loss. Every unit sold above the break even point generates profit. Every unit sold below it results in a loss. Understanding your break even point is one of the most fundamental concepts in business planning and financial management.
Our free break even calculator helps entrepreneurs, small business owners, students and financial analysts find the break even point instantly — in both units and revenue.
Break Even Formulas:
Contribution Margin = Selling Price - Variable Cost Per Unit
Contribution Margin % = (Contribution Margin / Selling Price) × 100
Break Even Units = Fixed Costs / Contribution Margin
Break Even Revenue = Fixed Costs / Contribution Margin %
Margin of Safety = Expected Sales - Break Even Units
Example:
Fixed Costs = $5,000/month
Selling Price = $25/unit
Variable Cost = $10/unit
Contribution Margin = $25 - $10 = $15/unit
Break Even = $5,000 / $15 = 334 units/month
Fixed Costs vs Variable Costs
Fixed costs remain constant regardless of how many units you produce or sell — rent, salaries, insurance and loan payments are examples. Variable costs change directly with production volume — raw materials, packaging, shipping and sales commissions are examples. Understanding the difference is critical to accurate break even analysis.
What is Contribution Margin?
Contribution margin is the amount each unit sold contributes toward covering fixed costs and generating profit. It is calculated as selling price minus variable cost per unit. A higher contribution margin means fewer units need to be sold to break even. Businesses with high contribution margins have more pricing flexibility and recover fixed costs faster.
How to Lower Your Break Even Point
- Increase your selling price — even a small price increase significantly lowers break even point
- Reduce fixed costs — renegotiate rent, reduce overhead or find cheaper suppliers
- Reduce variable costs — improve efficiency, negotiate bulk purchasing discounts
- Increase contribution margin — the most powerful lever for reducing break even point
- Focus on higher margin products or services in your product mix
Frequently Asked Questions
How do I calculate the break even point? +
Break even point in units = Fixed Costs / (Selling Price - Variable Cost Per Unit). The denominator is called the contribution margin. For example, if fixed costs are $5,000, selling price is $25 and variable cost is $10: Break even = $5,000 / ($25 - $10) = $5,000 / $15 = 334 units per month.
What is the break even point in sales revenue? +
Break even revenue = Fixed Costs / Contribution Margin Ratio. The contribution margin ratio = (Selling Price - Variable Cost) / Selling Price. For the example above: contribution margin ratio = $15/$25 = 60%. Break even revenue = $5,000 / 0.60 = $8,333. This means you need $8,333 in monthly revenue to break even.
What is margin of safety? +
Margin of safety is the difference between your expected or actual sales and your break even point. It shows how much sales can drop before you start making a loss. A higher margin of safety means your business is more financially secure. Margin of Safety = Expected Sales - Break Even Units. Expressed as a percentage: Margin of Safety % = (Margin of Safety / Expected Sales) × 100.
What is a good contribution margin? +
A good contribution margin varies by industry. Software and digital products often have contribution margins of 70-90%. Service businesses typically see 50-70%. Retail and manufacturing often see 20-40%. The higher the contribution margin, the fewer units you need to sell to break even and the faster profits accumulate above the break even point.
Can break even analysis be used for service businesses? +
Absolutely. For service businesses, replace units with hours or clients. Fixed costs are your overhead — office rent, salaries, software subscriptions. Variable costs are costs that increase with each client — materials, contractor fees, per-project expenses. Selling price is your hourly rate or project fee. The break even analysis works exactly the same way.
