About Break Even Units Calculator Online
This tool tells you how many units of a product you need to sell to cover your costs. Enter the fixed costs (rent, salaries, equipment), the variable cost per unit (materials, packaging), and your selling price per unit, and it calculates the break-even quantity.
Break-even analysis is fundamental for product launches, business plans, and pricing decisions. Below the break-even quantity, the business loses money; above it, every additional sale contributes to profit. Knowing this number is essential before committing to a manufacturing run or pricing strategy.
Use it to test pricing scenarios: lowering your price requires more units to break even, while raising it may price you out of the market. Try several variations to find the sweet spot.
How to use this tool
How to compute break-even units
Enter fixed costs
"Fixed costs" is the period's total cost that does NOT scale with units sold — rent, salaries, software, baseline marketing. Use the period (monthly / quarterly / yearly) consistently across all fields.
Price per unit
"Price / unit" is the average revenue per unit sold (after discounts, before taxes). For SaaS, this is ARPU; for physical goods, it's the typical sale price.
Variable cost per unit
"Variable cost / unit" is everything that scales 1:1 with units — COGS, payment processing fees, shipping, per-unit royalties. Must be less than price; otherwise contribution margin ≤ 0 and the tool errors out.
Press Run
Result returns breakEvenUnits = ceil(fixedCosts / (price − variableCost)). The ceiling means "the first whole unit that covers fixed costs" — fractional units round up because you can't ship half a product.
