- Enter fixed costs. Use costs for one consistent period, such as one month.
- Enter the average selling price. Use the net price after normal discounts.
- Enter variable cost per unit. Include product cost and other costs that rise with each sale.
- Review the threshold. Compare break-even units and revenue with realistic demand.
Retail Break Even Calculator
The Retail Break Even Calculator estimates the sales volume and revenue a store needs to cover its fixed and variable costs. It separates expenses that remain stable, such as rent and software, from costs that rise with each unit sold, such as product cost, packaging, and transaction fees.
Retail owners, category managers, and pop-up operators can use the result to set minimum sales targets, assess a new location, or test whether a planned price leaves enough contribution per unit. The calculator also shows contribution margin per unit and the margin ratio so you can see how strongly each sale helps absorb overhead. The result is a planning threshold, not a guarantee of profit, because actual product mix, discounts, returns, and cost changes can shift the break-even point.

Break-even revenue—
Contribution per unit—
Contribution margin ratio—
Break-even units = Fixed costs ÷ (Selling price per unit − Variable cost per unit)
Break-even revenue = Break-even units × Selling price per unit
Contribution margin ratio = (Selling price − Variable cost) ÷ Selling price
The model assumes one representative product or a stable blended average across products.
What the result means
The main result is the minimum whole number of units that must be sold during the selected period before operating profit becomes positive.
If price is not greater than variable cost, each sale does not contribute toward fixed costs and a finite break-even point cannot be calculated.
Given: fixed costs of $12,000, a $50 selling price, and $30 variable cost per unit.
Calculation: Contribution per unit = $50 − $30 = $20. Break-even units = $12,000 ÷ $20 = 600 units. Break-even revenue = 600 × $50 = $30,000.
Result: The store must sell 600 units, generating about $30,000 in revenue, to cover the modeled costs.
Should sales tax be included in the selling price?
Usually no. Use net revenue retained by the business, excluding taxes collected for authorities.
How should I handle several products?
Use weighted average selling price and variable cost based on the expected sales mix, or calculate each major product line separately.
Why is the result rounded up?
A partial unit cannot normally be sold, so break-even units are rounded up to the next whole unit.
Do owner wages count as fixed costs?
Include them when they are a recurring business expense for the period being analyzed.
How is break-even different from a sales target?
Break-even covers modeled costs only; a sales target may also include desired profit, cash needs, and a safety margin.
