Break Even Calculator

Break-Even Calculator — Free Business Revenue & Fixed Cost Analyzer

Calculate business break-even sales volumes (in units and currency) directly in your browser. Operating 100% client-side, this calculator projects profitability thresholds without transmitting business cost data.

Mathematical Formulas

1. Break-Even Volume (Units):

$$\text{BEP}_{units} = \frac{\text{Total Fixed Costs}}{\text{Selling Price per Unit} - \text{Variable Cost per Unit}}$$

2. Contribution Margin Ratio:

$$\text{CM Ratio} = \frac{\text{Selling Price} - \text{Variable Cost}}{\text{Selling Price}}$$

3. Break-Even Revenue Currency:

$$\text{BEP}_{revenue} = \frac{\text{Total Fixed Costs}}{\text{CM Ratio}}$$

How to Calculate Break-Even Step-by-Step

1. 1Enter Total Fixed Costs: Input overhead expenditures (rent, salaries, insurance, software).
2. 2Enter Unit Selling Price: Input retail or wholesale price charged per item.
3. 3Enter Unit Variable Cost: Input direct materials, shipping, and manufacturing cost per item.
4. 4Review Threshold: Inspect minimum unit sales required to reach zero net loss.

Practical Business Use Cases

• Product Launch Feasibility: Evaluate how many units a new product line must sell to cover R&D overhead.
• Pricing Strategy: Test how raising or lowering retail unit prices impacts required break-even volume.
• Business Loan Applications: Demonstrate clear financial profitability milestones to investors and banks.

Frequently Asked Questions (FAQs)

What is the difference between Fixed and Variable costs?

Fixed costs remain constant regardless of sales volume (e.g. rent). Variable costs change directly with production volume (e.g. raw materials, packaging).
