Break-Even Point Calculator
Find how many units you need to sell to cover your fixed costs.
Cómo funciona
The break-even point is the number of units a business needs to sell before it starts making a profit — below that number, total costs exceed revenue; above it, the business turns a profit.
The calculation starts with contribution margin: price per unit minus variable cost per unit (the cost that scales with each additional unit made or sold, like materials and direct labor). This margin represents how much each sale contributes toward covering fixed costs (rent, salaries, equipment — costs that don't change with sales volume) before any profit begins.
Break-even units = fixed costs ÷ contribution margin per unit. For a business with $10,000 in fixed costs, selling a product at $50 with $20 in variable cost per unit, the contribution margin is $30, so break-even units = 10,000 ÷ 30 ≈ 334 units. Break-even revenue is simply that unit count times the price: 334 × $50 ≈ $16,700.
This is a foundational calculation for pricing and planning decisions: it shows exactly how sensitive profitability is to volume, price, and cost changes. Raising the price, or reducing variable cost per unit, both increase the contribution margin and lower the number of units needed to break even — while an increase in fixed costs raises the break-even point.
If variable cost per unit is greater than or equal to the selling price, break-even becomes mathematically impossible — every unit sold loses money (or contributes nothing), so no sales volume, however large, would ever cover fixed costs. This is an important early warning sign in evaluating whether a pricing structure or cost base is viable at all.
Real businesses often use break-even analysis alongside sensitivity testing — running the numbers again with a higher or lower price, or a different cost structure, to understand how much cushion exists between current sales volume and the break-even threshold, and how a cost increase (like a supplier price hike) would shift that threshold.
What if price is less than variable cost?
Break-even is impossible in that case — each sale loses money regardless of volume.
What's the difference between fixed and variable costs?
Fixed costs (rent, salaries, insurance) stay the same regardless of how much you sell; variable costs (materials, direct labor per unit, shipping per order) scale directly with sales volume.
What is contribution margin, exactly?
The amount each unit sold contributes toward covering fixed costs, calculated as price per unit minus variable cost per unit — once enough units are sold to cover all fixed costs, contribution margin from further sales becomes profit.
How does raising prices affect the break-even point?
Raising price increases the contribution margin per unit, which lowers the number of units needed to reach break-even, all else equal.
How does an increase in fixed costs affect break-even?
It raises the break-even point directly — more units must be sold to cover the higher fixed cost base before reaching profitability.
Is break-even analysis only useful for physical products?
No — the same framework applies to services, subscriptions, or any revenue-generating activity with identifiable fixed and variable costs, though 'units' may represent customers, subscriptions, or billable hours instead of physical items.
What does break-even revenue tell me that break-even units doesn't?
It converts the unit threshold into a dollar sales target, which is often more directly useful for setting sales goals or comparing against actual revenue figures.
How is break-even analysis useful for a new business plan?
It shows investors and founders exactly how much sales volume is needed before the business becomes profitable, helping assess whether a business model and pricing strategy are realistic given expected demand.
Does break-even analysis account for taxes?
No — this is a pre-tax operational calculation focused on covering costs, not a full profitability model including tax effects.
How is break-even in dollars different from break-even in units?
Break-even units tells you how many items to sell; break-even revenue converts that into a dollar sales target (units × price) — both describe the same underlying threshold, just in different terms.
Can a business have multiple break-even points?
If it sells multiple products at different prices and costs, each product line can have its own break-even point, and a combined analysis (using a weighted average contribution margin) is needed for the business as a whole.
