Break Even Point Calculator
Find out exactly how many units you must sell before your business turns a profit. Essential for pricing decisions, startup planning, and evaluating new product lines.
About this calculator
The break-even point is the sales volume at which total revenue exactly equals total costs — neither profit nor loss. The formula is: Break-Even Units = Fixed Costs / (Price per Unit − Variable Cost per Unit). The denominator, (Price − Variable Cost), is called the contribution margin — the amount each sale contributes toward covering fixed costs. Fixed costs are expenses that don't change with output (rent, salaries), while variable costs scale with each unit produced (materials, packaging). Once break-even is reached, every additional unit sold generates pure profit equal to the contribution margin. This analysis is fundamental in pricing strategy, business planning, and risk assessment.
How to use
Imagine a small bakery with $3,000 in monthly fixed costs (rent, equipment). Each loaf sells for $8, and the ingredients cost $3 per loaf. Contribution margin = $8 − $3 = $5. Break-Even Units = $3,000 / $5 = 600 loaves. The bakery must sell 600 loaves per month before making any profit. Enter your own fixed costs, price per unit, and variable cost per unit to instantly find your break-even threshold.
Frequently asked questions
What is the difference between fixed costs and variable costs in break-even analysis?
Fixed costs remain constant regardless of how many units you produce — examples include rent, insurance, and salaried wages. Variable costs change directly with production volume — think raw materials, hourly labor, and shipping costs. Break-even analysis separates these two categories because fixed costs must be fully recovered before any profit is possible, while variable costs are already accounted for in the contribution margin. Misclassifying costs is one of the most common mistakes entrepreneurs make when running this analysis.
How can I use the break-even point to set a competitive selling price?
Start by estimating your fixed and variable costs, then decide on a target sales volume that feels realistic given your market. Rearrange the formula: Price = (Fixed Costs / Target Units) + Variable Cost per Unit. This gives you the minimum price needed to break even at that volume. From there you can add a desired profit margin on top. Comparing this minimum price to competitor pricing reveals whether your cost structure is competitive or needs improvement.
Why is break-even analysis important before launching a new product?
Before committing resources, break-even analysis tells you how many units must sell just to recover costs — giving you a concrete target to evaluate against realistic demand forecasts. If the break-even quantity exceeds what the market can absorb, the product will lose money and should be reconsidered. It also highlights which cost drivers — fixed overhead versus variable production costs — have the greatest impact on profitability, guiding decisions about outsourcing, pricing, or scale. Investors and lenders often require break-even projections as part of a business plan.
